Call a PHP script from bash

Requeriments:

At least one Meshlium

Sometimes people have asked us about the possibility of call PHP scripts within a shell script. This how to will show some tricks to do that.

First we need to have a PHP script accesible from a web navigator. For this examples we will assume that a folder named my_php_scripts is under /var/www.

Trick 1: Just call a script and forget about it's output

	#!/bin/bash
	wget -q http://localhost/my_php_scripts/script_1.php -O /dev/null

Trick 2: Call a script and save it's output in /tmp/output

	#!/bin/bash
	wget -q http://localhost/my_php_scripts/script_1.php -O /tmp/output

Trick 3: Call a script and store it's output in a variable

	#!/bin/bash
	VAR=$(wget -q -O - http://localhost/my_php_scripts/script_1.php)
	echo $VAR
