Answer 1

if you want to return something from an include_once call you have to return something in the file. See Example 5.

<?php // return.php
    $var = 'PHP';
    return $var;
?>

vs.

<?php // noreturn.php
     $var = 'PHP';
?>

gives

<?php
    $foo = include 'return.php';
    echo $foo; // prints 'PHP'

    $bar = include 'noreturn.php';
    echo $bar; // prints 1
 ?>
