multiple file upload controls for uploading to different locations PHP

See if the below helps:

Edited. The above will give you a basic upload however if you want to upload the files to 2 different folders on the server then alter the php script as below:

<?php
if(isset($_POST['submit'])){

// Count total files
$countfiles = count($_FILES['file']['name']);

// Looping all files

for($i=0;$i<$countfiles;$i++){
$filename = $_FILES['file']['name'][$i];
$folder_1 = 'uploads_1/' . $filename;
$folder_2 = 'uploads_2/' . $filename;

// Upload file
move_uploaded_file($_FILES['file']['tmp_name'][$i], $folder_1);
copy($folder_1, $folder_2);
}

}
?>

Of course this is as basic as it gets. You'd probably want to do a check as to which file extensions are allowed to be uploaded, max-size allowed etc.
