Aiutatemi a cambiare qusta riga - upload?

[king size slim]

cambia

If($random_name){
$file_name[$i]=time()+rand(0,100000).".".$ext;
} Else {
$file_name[$i]=$_FILES['file']['name'][$i];
} 

con

$file_name[$i]=$_FILES['file']['name'][$i]; 

e sei a posto

oppure ancora più semplicemente

$random_name = false;

If($random_name){
$file_name[$i]=time()+rand(0,100000).".".$ext;
} Else {
$file_name[$i]=$_FILES['file']['name'][$i];
}
