(PHP 4, PHP 5, PHP 7, PHP 8)
$argc — The number of argumens passed to script
Contains the number of argumens 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 reguister_argc_argv is disabled.
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)
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;
