init.inc.php

    <?php  $path = dirname(__file__);  include("youtube_api.inc.php");  ?> 

videos.php

<?php  header('content-type: text/plain');  include('init.inc.php');  print_r(get_latestvideo('thegigglesquid'));  ?> 

this last file supposed print $videos array.

you never return function.

try adding:

return $videos; 

at end of function, outside of if() {} else {} statement.

function get_latestvideo($username) {         $videos = array();     if (true || (time() - filetime("{$globals['path']}/cache/video_cache.txt")) > 3600) {         // ...     } else {         // ...     }     return $videos; // <-- important! }
