$argc

(PHP 4, PHP 5, PHP 7, PHP 8)

$argcThe number of arguments passed to script

Description

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

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

Note: This variable is not available when register_argc_argv is disabled.

Examples

Example #1 $argc example

<?php
var_dump
($argc);
?>

When executing the example with: php script.php arg1 arg2 arg3

The above example will output something similar to:

int(4)

Notes

Note:

This is also available as $_SERVER['argc'].

To find out are you in CLI or not, this is much better in my opinion:
<?php
if (PHP_SAPI != "cli") {
exit;
}
?>
