How does PHP handle file uploads and processing?

PHP handles file uploads and processing by using the $_FILES superglobal array to access uploaded file information and the move_uploaded_file() function to move the uploaded file to a specified directory on the server. Additionally, PHP provides various functions for file manipulation, such as file_get_contents() and file_put_contents(), to read and write file contents. 

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