problems with scalars

Hello everyone -
I wrote a function that handles uploads, and to call it variables are
defined like this:
function handleupload($gofile, $name, $size, $usersname) {
// the action goes here
}
However, I need to use the $_files array to call the uploaded files in a for
function. The first uploaded file is $_FILES['file1']['tmp_name'], and the
second is $_FILES['file2']['tmp_name'], and so on. How do I use the $i
scalar used in the for loop to replace 1 and 2 in the $_FILES array? I tried
these but they didnt work:

handleupload("$_FILES['file".$i."']['tmp_name']",
"$_FILES['file".$i."']['name']", "$_FILES['file".$i."']['size']",
$_COOKIE['cookie']['id']);
handleupload("$_FILES['file$I']['tmp_name']",
"$_FILES['file$i']['name']", "$_FILES['file$i']['size']", $username);

This is probably simple, but I'm new to this. So, how can I incorporate the
name of a scalar in another scalar's name in order to call a function?

Thanks,
Matt

Here's an example:

for ( $fileIndex = 0; $fileIndex < $max_file_uploads; ++$fileIndex ) {
move_uploaded_file($_FILES["file$fileIndex"]["tmp_name"], '../incoming');
}

In place, of ["file$fileIndex"] you may also use:

['file' . $fileIndex]

See <http://us2.php.net/manual/en/language.types.string.php> for
explanations on how to handle string interpolation.
