Question

My bash script call a php file

#!/bin/bash
data=$(./getconfig.php)

The file getconfig.php is:

#!/usr/bin/env php
<?php
$array = array();
...

How can I return the $array from the php file in order to manipulate this array in the bash script?

Answer 1

As per documentation, an array is initialized with the following syntax:

farm_hosts=(web03 web04 web05 web06 web07)

So all you need to do is implode your $array:

echo implode(' ', $array);
