Script formmail con allegati su altervista funziona altrove no

Ciao a tutti, ho un piccolo problema con uno script in php per mandare email con un allegato.
Con il sito hostato su altervista la cosa funzionava, mi arrivavano gli allegati integri, mentre con il nuovo hosting mi arrivano allegati danneggiati, ovvero con una dimensione pari a 0kb....
Non so se è un problema di codice perchè su un hosting funziona tutto bene sull'altro no.

Sotto posto il codice, non pretendo che ve lo leggiate, più che altro mi basta un consiglio su cosa vedere di sistemare o fare

function get_ext($key) { 
    $key=strtolower(substr(strrchr($key, "."), 1)); 
    // Cause there the same right? 
    $key=str_replace("jpeg","jpg",$key); 
    return $key; 
} 
 
function phattach($file,$name) { 
    global $boundary; 
     
    $fp=@fopen($file,"r"); 
    $str=@fread($fp, filesize($file)); 
    $str=@chunk_split(base64_encode($str)); 
    $message="--".$boundary."\n";
