Salve ragazzi il mio script mi dà quest'errore:

Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in c:\programmi\easyphp1-8\www\igem\menu.php on line 104


in seguito a questo mio codice:
$altez=0;
$larg=0;
size(&$altez,&$larg,$path);

<?
function size($altezza,$larghezza,$path){
$size[0]=getimagesize("$path");
$size[1]=getimagesize("$path");
$larghezza=$size[0];
$altezza=$size[1];
}
?>




Come mai non effettua il passaggio per indirizzo???
