$argcThe number of arguments passed to script


Contains the number of arguments passed to the current script when running from the command line.

Informacja: The script's filename is always passed as an argument to the script, therefore the minimum value of $argc is 1.

To find out are you in CLI or not, this is much better in my opinion:
if (PHP_SAPI != "cli") {

You can use php_sapi_name() to check whether it is cli or not

To decide whether my script is run from CLI I simply create a PHP script that handles only CLI invocations.

File cron.php:

// Set environment variables your application depends on
$_SERVER[ 'HTTP_HOST' ] = 'domain.tld';
// $_SERVER[ 'REQUEST_URI' ] = '/some/URI/if/needed';

// Use the environment to read out required values
$task = $_SERVER[ 'argv' ][ 1 ];

// Instanciate the dispatcher or whatever you use
$dispatcher = new Dispatcher();
$dispatcher->handle( $task );


This way my application doesn't have to know about CLI at all.

Note: when using CLI $argc (as well as $argv) are always available, regardless of register_argc_argv, as explained at http://docs.php.net/manual/en/features.commandline.php
