Question

I wanted to use PHP do do a little thing, but I needed to know how to get a variable from an external document (say external.php) and use it in a function in a PHP document (internal.php).
I was thinking maybe something like this:

Code for external.php

$variable = "true";

Code for internal.php

if ($GETFROM{'/external.php'}['variable']) 
echo "It worked";

Is there any possible way to do something like this?

If you want to include a specific value from an include file directly into a variable in your current document, you can also include a PHP file which returns the value.

For example:

inc.php

<?php
    return "Hello, world!";
?>

index.php

<?php
    $var = include "inc.php";

    if(isset($var) && !empty($var)) {
        echo "It worked!\n";
        echo "Value: {$var}";
    }
    else {
        echo "It failed!";
    }
?>
