problemas con php

[ahaugas]

NO ME FUNCIONA o no lo estoy poniendo bien HE PUESTO ESTO como me has dicho

Código PHP:

if ($content = curl_init("http://www.megavideo.com/xml/videolink.php?v=".$megavideo_id."&u=XXXXXXXXXXXXXXXXXXXXXXXX--XXXXX")){
    curl_setopt($content, CURLOPT_RETURNTRANSFER, true);
    $var = curl_exec($content);
    curl_close($content);
 

el codigo original es este

Código PHP:
