[PHP] $_FILES help. Counting help

[Didier McGillis]

I have three file fields in a form.  I need it to upload those three items 
or two or one.  I can get it to upload one, but not all three, habing 
trouble with the for loop and how I get a value of $i.

if(isset($_POST['upload'])){
   if (!empty($_FILES['file']['name'])){
           $formats = array('mp3','exe');
           
if(in_array(strtolower(substr($_FILES['file']['name'],-3)),$formats)) {
               echo "<font face=\"verdana,arial,helvetica\" size=\"2\" 
color=\"#000000\"><b>Sorry! MP3's and .EXE's are disallowed!</b></font>";
           }else{
               //mkdir("upload/" . $_POST['dir'],0777);
               copy($_FILES['file']['tmp_name'], "images/" . 
$_FILES['file']['name']);
               unlink($_FILES['file']['tmp_name']);
               echo "<font face=\"verdana,arial,helvetica\" size=\"2\" 
color=\"#000000\"><b>".$i." File(s) Uploaded Successfully to <b>" . 
$_POST['dir'] . "</b> directory!</b></font>";
           }
   }else{
       echo "<font face=\"verdana,arial,helvetica\" size=\"2\" 
color=\"#000000\"><b>You must specify a file to upload</b></font><br>\n";
       echo "<font face=\"verdana,arial,helvetica\" size=\"2\" 
color=\"#000000\"><a href=\"javascript:history.back()\">< < 
back</a></font><br>\n";
       exit();
   }
}

$i =$_FILES['file']['name'];
is it for ($i=1;$i<4;i++) {
run code
}
or am I way off, help please.

thanks,
