What is the challenge of passing the $_FILES[] array after multiple uploads within a file in PHP?

When multiple files are uploaded within a single form field in PHP, the $_FILES[] array will have a slightly different structure compared to uploading files separately. To access these files, you need to loop through the array and handle each file individually. You can use a foreach loop to iterate over the $_FILES array and process each file accordingly. 

foreach($_FILES['file']['tmp_name'] as $key => $tmp_name) {
    $file_name = $_FILES['file']['name'][$key];
    $file_size = $_FILES['file']['size'][$key];
    $file_tmp = $_FILES['file']['tmp_name'][$key];
    
    // Process each file here
}
