How can PHP programmers access uploaded files using the $_FILES array and what information does it provide?

To access uploaded files using the $_FILES array in PHP, programmers can use the 'name', 'type', 'tmp_name', 'error', and 'size' keys provided in the $_FILES array. This information allows programmers to handle the uploaded file, such as moving it to a specific directory, checking its file type, and validating its size. 

<?php
if(isset($_FILES['file'])){
    $file_name = $_FILES['file']['name'];
    $file_type = $_FILES['file']['type'];
    $file_tmp_name = $_FILES['file']['tmp_name'];
    $file_error = $_FILES['file']['error'];
    $file_size = $_FILES['file']['size'];
    
    // Further processing of the uploaded file
}
?>
