In the context of PHP file uploads, what considerations should be made when processing multiple files using arrays?

When processing multiple files using arrays in PHP file uploads, it is important to loop through the array of files and handle each file individually. This allows for separate processing of each file, such as validation, saving to a database, or moving to a specific directory. By iterating over the array of files, you can ensure that each file is processed correctly without any conflicts or issues. 

<?php
if(isset($_FILES['files'])){
    $files = $_FILES['files'];
    
    foreach($files['tmp_name'] as $key => $tmp_name){
        $file_name = $files['name'][$key];
        $file_size = $files['size'][$key];
        $file_tmp = $tmp_name;
        $file_type = $files['type'][$key];
        
        // Process each file here (e.g. validate, save, move)
        
        // Example: move uploaded file to a specific directory
        $upload_dir = 'uploads/';
        move_uploaded_file($file_tmp, $upload_dir . $file_name);
    }
}
?>
