dallo stesso script io ho adattato questo, buono studio:
Codice PHP:

//change to fit your need eg. files, upload .... etc.
$upload_dir = "images/";
//number of files to upload.
$num_files = 5;
//the file size in bytes.
$size_bytes =52428800; //51200 bytes = 50KB.
//Extensions you want files uploaded limited to.
$limitedext = array(".gif",".jpg",".jpeg",".png",".txt",".nfo",".doc",".rtf",".htm",".dmg",".zip",".rar",".gz",".exe",".rar",".zip");
//check if the directory exists or not.
if (!is_dir("$upload_dir")) {
die ("Error: The directory [b]($upload_dir)[/b] doesn't exist");
}
//check if the directory is writable.
if (!is_writeable("$upload_dir")){
die ("Error: The directory [b]($upload_dir)[/b] is NOT writable, Please CHMOD (777)");
}
//if the form has been submitted, then do the upload process
//infact, if you clicked on (Upload Now!) button.
if (isset($_POST['upload_form'])){
echo "<h3>Upload results:</h3>";
//do a loop for uploading files based on ($num_files) number of files.
for ($i = 1; $i <= $num_files; $i++) {
//define variables to hold the values.
$new_file = $_FILES['file'.$i];
$file_name = $new_file['name'];
//to remove spaces from file name we have to replace it with "_".
$file_name = str_replace(' ', '_', $file_name);
$file_tmp = $new_file['tmp_name'];
$file_size = $new_file['size'];
#-----------------------------------------------------------#
