What is the significance of the $_FILES variable in PHP upload scripts?

The $_FILES variable in PHP upload scripts is significant because it contains information about a file that has been uploaded via a form. This variable allows you to access details such as the file name, file type, file size, and temporary location of the uploaded file. By using the $_FILES variable, you can process the uploaded file, move it to a permanent location, and perform any necessary validations or checks on the file before saving it. 

<?php
if(isset($_FILES['file'])){
    $file_name = $_FILES['file']['name'];
    $file_tmp = $_FILES['file']['tmp_name'];
    $file_size = $_FILES['file']['size'];
    $file_type = $_FILES['file']['type'];
    
    // Process the uploaded file here
    
    move_uploaded_file($file_tmp, "uploads/" . $file_name);
}
?>
