You can easily parse command line arguments into the $_GET variable by using the parse_str() function.
<?php
parse_str(implode('&', array_slice($argv, 1)), $_GET);
?>
It behaves exactly like you'd expect with cgi-php.
$ php -f somefile.php a=1 b[]=2 b[]=3
This will set $_GET['a'] to '1' and $_GET['b'] to array('2', '3').
Even better, instead of putting that line in every file, take advantage of PHP's auto_prepend_file directive. Put that line in its own file and set the auto_prepend_file directive in your cli-specific php.ini like so:
auto_prepend_file = "/etc/php/cli-php5.3/local.prepend.php"
It will be automatically prepended to any PHP file run from the command line.

Check directly without calling functions:
<?php
if (PHP_SAPI === 'cli')
{
// ...
}
?>
You can define a constant to use it elsewhere
<?php
define('ISCLI', PHP_SAPI === 'cli');

Parsing command line: optimization is evil!
One thing all contributors on this page forgotten is that you can suround an argv with single or double quotes. So the join coupled together with the preg_match_all will always break that :)
Here is a proposal:
#!/usr/bin/php
<?php
print_r(arguments($argv));
function arguments ( $args )
{
array_shift( $args );
$endofoptions = false;
$ret = array
(
'commands' => array(),
'options' => array(),
'flags' => array(),
'arguments' => array(),
);
while ( $arg = array_shift($args) )
{
// if we have reached end of options,
//we cast all remaining argvs as arguments
if ($endofoptions)
{
$ret['arguments'][] = $arg;
continue;
}
// Is it a command? (prefixed with --)
if ( substr( $arg, 0, 2 ) === '--' )
{
// is it the end of options flag?
if (!isset ($arg[3]))
{
$endofoptions = true;; // end of options;
continue;
}
$value = "";
$com = substr( $arg, 2 );
// is it the syntax '--option=argument'?
if (strpos($com,'='))
list($com,$value) = split("=",$com,2);
// is the option not followed by another option but by arguments
elseif (strpos($args[0],'-') !== 0)
{
while (strpos($args[0],'-') !== 0)
$value .= array_shift($args).' ';
$value = rtrim($value,' ');
}
$ret['options'][$com] = !empty($value) ? $value : true;
continue;
}
// Is it a flag or a serial of flags? (prefixed with -)
if ( substr( $arg, 0, 1 ) === '-' )
{
for ($i = 1; isset($arg[$i]) ; $i++)
$ret['flags'][] = $arg[$i];
continue;
}
// finally, it is not option, nor flag, nor argument
$ret['commands'][] = $arg;
continue;
}
if (!count($ret['options']) && !count($ret['flags']))
{
$ret['arguments'] = array_merge($ret['commands'], $ret['arguments']);
$ret['commands'] = array();
}
return $ret;

Ok, I've had a heck of a time with PHP > 4.3.x and whether to use CLI vs CGI. The CGI version of 4.3.2 would return (in browser):
---
No input file specified.
---
And the CLI version would return:
---
500 Internal Server Error
---
It appears that in CGI mode, PHP looks at the environment variable PATH_TRANSLATED to determine the script to execute and ignores command line. That is why in the absensce of this environment variable, you get "No input file specified." However, in CLI mode the HTTP headers are not printed. I believe this is intended behavior for both situations but creates a problem when you have a CGI wrapper that sends environment variables but passes the actual script name on the command line.
By modifying my CGI wrapper to create this PATH_TRANSLATED environment variable, it solved my problem, and I was able to run the CGI build of 4.3.2

Just a note for people trying to use interactive mode from the commandline.
The purpose of interactive mode is to parse code snippits without actually leaving php, and it works like this:
[root@localhost php-4.3.4]# php -a
Interactive mode enabled
<?php echo "hi!"; ?>
<note, here we would press CTRL-D to parse everything we've entered so far>
hi!
<?php exit(); ?>
<ctrl-d here again>
[root@localhost php-4.3.4]#
I noticed this somehow got ommited from the docs, hope it helps someone!

If you want to be interactive with the user and accept user input, all you need to do is read from stdin.
<?php
echo "Are you sure you want to do this? Type 'yes' to continue: ";
$handle = fopen ("php://stdin","r");
$line = fgets($handle);
if(trim($line) != 'yes'){
echo "ABORTING!\n";
exit;
}
echo "\n";
echo "Thank you, continuing...\n";

How to change current directory in PHP script to script's directory when running it from command line using PHP 4.3.0?
(you'll probably need to add this to older scripts when running them under PHP 4.3.0 for backwards compatibility)
Here's what I am using:
chdir(preg_replace('/\\/[^\\/]+$/',"",$PHP_SELF));
Note: documentation says that "PHP_SELF" is not available in command-line PHP scripts. Though, it IS available. Probably this will be changed in future version, so don't rely on this line of code...
Use $_SERVER['PHP_SELF'] instead of just $PHP_SELF if you have register_globals=Off

Using CLI (on WIN at least), some INI paths are relative to the current working directory. For example, if your error_log = "php_errors.log", then php_errors.log will be created (or appended to if already exists) in whatever directory you happen to be in at the moment if you have write access there. Instead of having random error logs all over the place because of this behavior, you may want to set error_log to a full path, perhaps to the php.exe directory.

If your php script doesn't run with shebang (#!/usr/bin/php),
and it issues the beautifull and informative error message:
"Command not found." just dos2unix yourscript.php
et voila.
If you still get the "Command not found."
Just try to run it as ./myscript.php , with the "./"
if it works - it means your current directory is not in the executable search path.
If your php script doesn't run with shebang (#/usr/bin/php),
and it issues the beautifull and informative message:
"Invalid null command." it's probably because the "!" is missing in the the shebang line (like what's above) or something else in that area.

For those of you who want the old CGI behaviour that changes to the actual directory of the script use:
chdir(dirname($_SERVER['argv'][0]));
at the beginning of your scripts.

You can also call the script from the command line after chmod'ing the file (ie: chmod 755 file.php).
On your first line of the file, enter "#!/usr/bin/php" (or to wherever your php executable is located). If you want to suppress the PHP headers, use the line of "#!/usr/bin/php -q" for your path.

In 5.1.2 (and others, I assume), the -f form silently drops the first argument after the script name from $_SERVER['argv']. I'd suggest avoiding it unless you need it for a special case.

i use emacs in c-mode for editing. in 4.3, starting a cli script like so:
#!/usr/bin/php -q /* -*- c -*- */
<?php
told emacs to drop into c-mode automatically when i loaded the file for editing. the '-q' flag didn't actually do anything (in the older cgi versions, it suppressed html output when the script was run) but it caused the commented mode line to be ignored by php.
in 5.2, '-q' has apparently been deprecated. replace it with '--' to achieve the 4.3 invocation-with-emacs-mode-line behavior:
#!/usr/bin/php -- /* -*- c -*- */
<?php
don't go back to your 4.3 system and replace '-q' with '--'; it seems to cause php to hang waiting on STDIN...

Spawning php-win.exe as a child process to handle scripting in Windows applications has a few quirks (all having to do with pipes between Windows apps and console apps).
To do this in C++:
// We will run php.exe as a child process after creating
// two pipes and attaching them to stdin and stdout
// of the child process
// Define sa struct such that child inherits our handles
SECURITY_ATTRIBUTES sa = { sizeof(SECURITY_ATTRIBUTES) };
sa.bInheritHandle = TRUE;
sa.lpSecurityDescriptor = NULL;
// Create the handles for our two pipes (two handles per pipe, one for each end)
// We will have one pipe for stdin, and one for stdout, each with a READ and WRITE end
HANDLE hStdoutRd, hStdoutWr, hStdinRd, hStdinWr;
// Now create the pipes, and make them inheritable
CreatePipe (&hStdoutRd, &hStdoutWr, &sa, 0))
SetHandleInformation(hStdoutRd, HANDLE_FLAG_INHERIT, 0);
CreatePipe (&hStdinRd, &hStdinWr, &sa, 0)
SetHandleInformation(hStdinWr, HANDLE_FLAG_INHERIT, 0);
// Now we have two pipes, we can create the process
// First, fill out the usage structs
STARTUPINFO si = { sizeof(STARTUPINFO) };
PROCESS_INFORMATION pi;
si.dwFlags = STARTF_USESTDHANDLES;
si.hStdOutput = hStdoutWr;
si.hStdInput = hStdinRd;
// And finally, create the process
CreateProcess (NULL, "c:\\php\\php-win.exe", NULL, NULL, TRUE, NORMAL_PRIORITY_CLASS, NULL, NULL, &si, &pi);
// Close the handles we aren't using
CloseHandle(hStdoutWr);
CloseHandle(hStdinRd);
// Now that we have the process running, we can start pushing PHP at it
WriteFile(hStdinWr, "<?php echo 'test'; ?>", 9, &dwWritten, NULL);
// When we're done writing to stdin, we close that pipe
CloseHandle(hStdinWr);
// Reading from stdout is only slightly more complicated
int i;
std::string processed("");
char buf[128];
while ( (ReadFile(hStdoutRd, buf, 128, &dwRead, NULL) && (dwRead != 0)) ) {
for (i = 0; i < dwRead; i++)
processed += buf[i];
}
// Done reading, so close this handle too
CloseHandle(hStdoutRd);

TIP: If you want different versions of the configuration file depending on what SAPI is used,just name them php.ini (apache module), php-cli.ini (CLI) and php-cgi.ini (CGI) and dump them all in the regular configuration directory. I.e no need to compile several versions of php anymore!

To hand over the GET-variables in interactive mode like in HTTP-Mode (e.g. your URI is myprog.html?hugo=bla&bla=hugo), you have to call
php myprog.html '&hugo=bla&bla=hugo'
(two & instead of ? and &!)
There just a little difference in the $ARGC, $ARGV values, but I think this is in those cases not relevant.

Parsing commandline argument GET String without changing the PHP script (linux shell):
URL: index.php?a=1&b=2
Result: output.html
echo "" | php -R 'include("index.php");' -B 'parse_str($argv[1], $_GET);' 'a=1&b=2' >output.html
(no need to change php.ini)
You can put this
echo "" | php -R 'include("'$1'");' -B 'parse_str($argv[1], $_GET);' "$2"
in a bash script "php_get" to use it like this:
php_get index.php 'a=1&b=2' >output.html
or directed to text browser...
php_get index.php 'a=1&b=2' |w3m -T text/html

dunno if this is on linux the same but on windows evertime
you send somthing to the console screen php is waiting for
the console to return. therefor if you send a lot of small
short amounts of text, the console is starting to be using
more cpu-cycles then php and thus slowing the script.
take a look at this sheme:
cpu-cycle:1 ->php: print("a");
cpu-cycle:2 ->cmd: output("a");
cpu-cycle:3 ->php: print("b");
cpu-cycle:4 ->cmd: output("b");
cpu-cycle:5 ->php: print("c");
cpu-cycle:6 ->cmd: output("c");
cpu-cylce:7 ->php: print("d");
cpu-cycle:8 ->cmd: output("d");
cpu-cylce:9 ->php: print("e");
cpu-cycle:0 ->cmd: output("e");
on the screen just appears "abcde". but if you write
your script this way it will be far more faster:
cpu-cycle:1 ->php: ob_start();
cpu-cycle:2 ->php: print("abc");
cpu-cycle:3 ->php: print("de");
cpu-cycle:4 ->php: $data = ob_get_contents();
cpu-cycle:5 ->php: ob_end_clean();
cpu-cycle:6 ->php: print($data);
cpu-cycle:7 ->cmd: output("abcde");
now this is just a small example but if you are writing an
app that is outputting a lot to the console, i.e. a text
based screen with frequent updates, then its much better
to first cach all output, and output is as one big chunk of
text instead of one char a the time.
ouput buffering is ideal for this. in my script i outputted
almost 4000chars of info and just by caching it first, it
speeded up by almost 400% and dropped cpu-usage.
because what is being displayed doesn't matter, be it 2
chars or 40.0000 chars, just the call to output takes a
great deal of time. remeber that.
maybe someone can test if this is the same on unix-based
systems. it seems that the STDOUT stream just waits for
the console to report ready, before continueing execution.

To display colored text when it is actually supported :
<?php

echo "\033[41m".$myvar; // red background
?>
To reset these settings :
<?php
echo "\033[0m";

More fun :
<?php
echo "\033[5;30m;\033[48mWARNING !"; // black blinking text over red background

This posting is not a php-only problem, but hopefully will save someone a few hours of headaches. Running on MacOS (although this could happen on any *nix I suppose), I was unable to get the script to execute without specifically envoking php from the command line:
[macg4:valencia/jobs] tim% test.php
./test.php: Command not found.
However, it worked just fine when php was envoked on the command line:
[macg4:valencia/jobs] tim% php test.php
Well, here we are... Now what?
Was file access mode set for executable? Yup.
[macg4:valencia/jobs] tim% ls -l
total 16
-rwxr-xr-x 1 tim staff 242 Feb 24 17:23 test.php
And you did, of course, remember to add the php command as the first line of your script, yeah? Of course.
#!/usr/bin/php
<?php print "Well, here we are... Now what?\n"; ?>
So why dudn't it work? Well, like I said... on a Mac.... but I also occasionally edit the files on my Windows portable (i.e. when I'm travelling and don't have my trusty Mac available)... Using, say, WordPad on Windows... and BBEdit on the Mac...
Aaahhh... in BBEdit check how the file is being saved! Mac? Unix? or Dos? Bingo. It had been saved as Dos format. Change it to Unix:
[macg4:valencia/jobs] tim% ./test.php
Well, here we are... Now what?
[macg4:valencia/jobs] tim%
NB: If you're editing your php files on multiple platforms (i.e. Windows and Linux), make sure you double check the files are saved in a Unix format... those \r's and \n's 'll bite cha!

If you edit a php file in windows, upload and run it on linux with command line method. You may encounter a running problem probably like that:
[root@ItsCloud02 wsdl]# ./lnxcli.php
Extension './lnxcli.php' not present.
Or you may encounter some other strange problem.
Care the enter key. In windows environment, enter key generate two binary characters '0D0A'. But in Linux, enter key generate just only a 'OA'.
I wish it can help someone if you are using windows to code php and run it as a command line program on linux.

Assuming --prefix=/usr/local/php, it's better to create a symlink from /usr/bin/php or /usr/local/bin/php to target /usr/local/php/bin/php so that it's both in your path and automatically correct every time you rebuild. If you forgot to do that copy of the binary after a rebuild, you can do all kinds of wild goose chasing when things break.

In *nix systems, use the WHICH command to show the location of the php binary executable. This is the path to use as the first line in your php shell script file. (#!/path/to/php -q) And execute php from the command line with the -v switch to see what version you are running.
example:
# which php
/usr/local/bin/php
# php -v
PHP 4.3.1 (cli) (built: Mar 27 2003 14:41:51)
Copyright (c) 1997-2002 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2002 Zend Technologies
In the above example, you would use: #!/usr/local/bin/php
Also note that, if you do not have the current/default directory in your PATH (.), you will have to use ./scriptfilename to execute your script file from the command line (or you will receive a "command not found" error). Use the ENV command to show your PATH environment variable value.

I was looking for a way to interactively get a single character response from user. Using STDIN with fread, fgets and such will only work after pressing enter. So I came up with this instead:
#!/usr/bin/php -q
<?php
function inKey($vals) {
$inKey = "";
While(!in_array($inKey,$vals)) {
$inKey = trim(`read -s -n1 valu;echo \$valu`);
}
return $inKey;
}
function echoAT($Row,$Col,$prompt="") {
// Display prompt at specific screen coords
echo "\033[".$Row.";".$Col."H".$prompt;
}
// Display prompt at position 10,10
echoAT(10,10,"Opt : ");
// Define acceptable responses
$options = array("1","2","3","4","X");
// Get user response
$key = inKey($options);
// Display user response & exit
echoAT(12,10,"Pressed : $key\n");
?>
Hope this helps someone.

One of the things I like about perl and vbscripts, is the fact that I can name a file e.g. 'test.pl' and just have to type 'test, without the .pl extension' on the windows command line and the command processor knows that it is a perl file and executes it using the perl command interpreter.
I did the same with the file extension .php3 (I will use php3 exclusivelly for command line php scripts, I'm doing this because my text editor VIM 6.3 already has the correct syntax highlighting for .php3 files ).
I modified the PATHEXT environment variable in Windows XP, from the " 'system' control panel applet->'Advanced' tab->'Environment Variables' button-> 'System variables' text area".
Then from control panel "Folder Options" applet-> 'File Types' tab, I added a new file extention (php3), using the button 'New' and typing php3 in the window that pops up.
Then in the 'Details for php3 extention' area I used the 'Change' button to look for the Php.exe executable so that the php3 file extentions are associated with the php executable.
You have to modify also the 'PATH' environment variable, pointing to the folder where the php executable is installed
Hope this is useful to somebody

I've just found that the fact that the CLI does *not* change the current directory will make include() and require() calls with relative paths fail. This is because they are relative to the current directory, not to the current executing file, the documentation notwithstanding. In CGI mode, this is the same because it changes the current directory.
One solution is to call the CGI binary rather than the CLI one. A better solutions is to use dirname(__FILE__) in your path names.

Hi,
This function clears the screen, like "clear screen"
<?php
function clearscreen($out = TRUE) {
$clearscreen = chr(27)."[H".chr(27)."[2J";
if ($out) print $clearscreen;
else return $clearscreen;
}
?>

Example 43-2 shows how to create a DOS batch file to run a PHP script form the command line using:
@c:\php\cli\php.exe script.php %1 %2 %3 %4
Here is an updated version of the DOS batch file:
@c:\php\cli\php.exe %~n0.php %*
This will run a PHP file (i.e. script.php) with the same base file name (i.e. script) as the DOS batch file (i.e. script.bat) and pass all parameters (not just the first four as in example 43-2) from the DOS batch file to the PHP file.
This way all you have to do is copy/rename the DOS batch file to match the name of your PHP script file without ever having to actually modify the contents of the DOS batch file to match the file name of the PHP script.

This took me all day to figure out, so I hope posting it here saves someone some time:
Your PHP-CLI may have a different php.ini than your apache-php. For example: On my Debian-based system, I discovered I have /etc/php4/apache/php.ini and /etc/php4/cli/php.ini
If you want MySQL support in the CLI, make sure the line
extension=mysql.so
is not commented out.
The differences in php.ini files may also be why some scripts will work when called through a web browser, but will not work when called via the command line.

In the notes it there is an example of running 1 line of PHP using:
php -r 'print_r(get_defined_constants());'
This might work on a UNIX machine but unfortunately on windows it produces the following error message:
Parse error: parse error in Command line code on line 1
Instead of using ' (single quotes) to encompass the PHP code use " (double quotes) instead. You can safely use ' within the code itself however such as:
php -r "echo 'hello';"

I'm figuring out how to pipe an email to a php script with postfix. For the email user@example.com:
I created the following line in /etc/aliases:
user: "|/www/file.php"
file.php is chmod 755
This works fine. But I wanted to test this without having to send an email every time. And this took some searching to figure out, yet it's oh-so simple:
To pipe the file email.txt to the script, write the following in the terminal window:
user@host: php file.php < testepost.txt
I was confused by the | in the aliases file, and didn't get what came after what, etc etc.

If a module SAPI is chosen during configure, such as apxs, or the --disable-cgi option is used, the CLI is copied to {PREFIX}/bin/php during make install otherwise the CGI is placed there.
versus
Changed CGI install target to php-cgi and 'make install' to install CLI when CGI is selected. (changelog for 5.2.3)

If you want to get the output of a command use the function shell_exec($command) - it returns a string with the output of the command.

You could use the Linux way of knowing that everything went ok by dying with a numeric code: 0 if everything went ok and practically anything else if something goes terribly wrong. That way;
<?php // hello.php
echo 'hello';
exit(0);
?>
<?php // bye.php
echo 'bye';
exit(1);
?>
<?php // hello-again.php
echo 'hi world!';
exit(0);
?>
calling:
php hello.php && php bye.php && php hello-again.php
would only execute the first two scripts, the last one doesn't get executed because an error ocurred in that script.
Greetings.

To pass more than 9 arguments to your php-script on Windows, you can use the 'shift'-command in a batch file. After using 'shift', %1 becomes %0, %2 becomes %1 and so on - so you can fetch argument 10 etc.
Here's an example - hopefully ready-to-use - batch file:
foo.bat:
---------
@echo off
:init_arg
set args=
:get_arg
shift
if "%0"=="" goto :finish_arg
set args=%args% %0
goto :get_arg
:finish_arg
set php=C:\path\to\php.exe
set ini=C:\path\to\php.ini
%php% -c %ini% foo.php %args%
---------
Usage on commandline:
foo -1 -2 -3 -4 -5 -6 -7 -8 -9 -foo -bar
A print_r($argv) will give you all of the passed arguments.

use " instead of ' on windows when using the cli version with -r
php -r "echo 1"
-- correct
php -r 'echo 1'
PHP Parse error: syntax error, unexpected ''echo' (T_ENCAPSED_AND_WHITESPACE), expecting end of file in Command line code on line 1

For command-line option definition and parsing, don't forget about the beauty of getopt().
There's a php-native version (http://php.net/getopt) and a PEAR package -- Console_GetOpt (http://pear.php.net/package/Console_Getopt).

If you are using Windows XP (I think this works on 2000, too) and you want to be able to right-click a .php file and run it from the command line, follow these steps:
1. Run regedit.exe and *back up the registry.*
2. Open HKEY_CLASSES_ROOT and find the ".php" key.
IF IT EXISTS:
------------------
3. Look at the "(Default)" value inside it and find the key in HKEY_CLASSES_ROOT with that name.
4. Open the "shell" key inside that key. Skip to 8.
IF IT DOESN'T:
------------------
5. Add a ".php" key and set the "(Default)" value inside it to something like "phpscriptfile".
6. Create another key in HKEY_CLASSES_ROOT called "phpscriptfile" or whatever you chose.
7. Create a key inside that one called "shell".
8. Create a key inside that one called "run".
9. Set the "(Default)" value inside "run" to whatever you want the menu option to be (e.g. "Run").
10. Create a key inside "run" called "command".
11. Set the "(Default)" value inside "command" to:
cmd.exe /k C:\php\php.exe "%1"
Make sure the path to PHP is appropriate for your installation. Why not just run it with php.exe directly? Because you (presumably) want the console window to remain open after the script ends.
You don't need to set up a webserver for this to work. I downloaded PHP just so I could run scripts on my computer. Hope this is useful!

Use PHP as Scripting Language in Windows Vista and 7:
ASSOC .phs=PHPScript
FTPYE PHPScript=[path to]\php.exe -f "%1" -- %*
optional set PATHEXT=.phs;%PATHEXT%
now you can execute any php-script (ext: .phs) from the shell like a .vbs or .cmd.
"c:\testscript.phs arg1 arg2" or with the optional step "c:\testscript arg1 arg2"
i hope this helps somebody.

I had problems running php as CGI in thttpd. I have followed instructions posted by db at digitalmediacreation dot ch, but I was still getting "500 Internal Error" answer from the server. However, I had no problems running php as CLI using a simple wrapper file named index.cgi:
#!/usr/bin/php
<?php
require_once 'index.php';
?>
but i needed to pass user data through GET and POST, and this method couldn't handle it. I have spent 2 hours figuring out how to run the CGI mode properly, until I finally gave up, and done it in "manual" way. I have just added some code to the wrapper that reads GET and POST data into the proper variables:
#!/usr/bin/php
<?php
//parse the command line into the $_GET variable
parse_str($_SERVER['QUERY_STRING'], $_GET);
//parse the standard input into the $_POST variable
if (($_SERVER['REQUEST_METHOD'] === 'POST')
&& ($_SERVER['CONTENT_LENGTH'] > 0))
{
parse_str(fread(STDIN, $_SERVER['CONTENT_LENGTH']), $_POST);
}
require_once 'index.php';
?>
It works well for me. It may be useful if someone else have similar problem.

Here's <losbrutos at free dot fr> function modified to support unix like param syntax like <B Crawford> mentions:
<?php
function arguments($argv) {
$_ARG = array();
foreach ($argv as $arg) {
if (preg_match('#^-{1,2}([a-zA-Z0-9]*)=?(.*)$#', $arg, $matches)) {
$key = $matches[1];
switch ($matches[2]) {
case '':
case 'true':
$arg = true;
break;
case 'false':
$arg = false;
break;
default:
$arg = $matches[2];
}
/* make unix like -afd == -a -f -d */
if(preg_match("/^-([a-zA-Z0-9]+)/", $matches[0], $match)) {
$string = $match[1];
for($i=0; strlen($string) > $i; $i++) {
$_ARG[$string[$i]] = true;
}
} else {
$_ARG[$key] = $arg;
}
} else {
$_ARG['input'][] = $arg;
}
}
return $_ARG;
}
?>
Sample:
eromero@ditto ~/workspace/snipplets $ foxogg2mp3.php asdf asdf --help --dest=/var/ -asd -h
Array
(
[input] => Array
(
[0] => /usr/local/bin/foxogg2mp3.php
[1] => asdf
[2] => asdf
)
[help] => 1
[dest] => /var/
[a] => 1
[s] => 1
[d] => 1
[h] => 1
)

If you are trying to set up an interactive command line script and you want to get started straight away (works on 4+ I hope). Here is some code to start you off:
<?php
// Stop the script giving time out errors..
set_time_limit(0);
// This opens standard in ready for interactive input..
define('STDIN',fopen("php://stdin","r"));
// Main event loop to capture top level command..
while(!0)
{
// Print out main menu..
echo "Select an option..\n\n";
echo " 1) Do this\n";
echo " 2) Do this\n";
echo " 3) Do this\n";
echo " x) Exit\n";
// Decide what menu option to select based on input..
switch(trim(fgets(STDIN,256)))
{
case 1:
break;
case 2:
break;
case 3:
break;
case "x":
exit();
default:
break;
}
}
// Close standard in..
fclose(STDIN);
?>
