how to make a PHP file run-able only through CLI mode?

Question

It's available to browser,

but I don't want it to execute when browsed by user,

say,when browsed should exit,

is there a way to detect whether it's currently Cmmand Line Mode?

Answer 1

Here is what i'm using, for a long time now... (since php 4 iirc)

(PHP_SAPI !== 'cli' || isset($_SERVER['HTTP_USER_AGENT'])) && die('cli only');

to be used as first line of the php script.

Answer 2

Here is a trick:

You can check for the $argc/$argv parameters which are always available in CLI mode.

#!/usr/bin/php
<?php 

ini_set('register_argc_argv', 0);  

if (!isset($argc) || is_null($argc))
{ 
    echo 'Not CLI mode';
} else {
    echo 'CLI mode';
}

register_argc_argv

$argc

Answer 3

Another trick, $_SERVER has variables that are only set in CLI mode.

Answer 4

if (!defined('STDIN')) {
    // accessed through the web browser
    die();
}

I use this when creating PHP CLI scripts. Works very well.
