How can PHP developers optimize their file upload scripts to handle larger file sizes more efficiently and effectively?

Issue: PHP developers can optimize their file upload scripts to handle larger file sizes more efficiently by increasing the PHP configuration settings related to file uploads, such as `upload_max_filesize` and `post_max_size`, and by using server-side validation to check the file size before processing it. 

// Increase PHP configuration settings for file uploads
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');

// Server-side validation to check file size before processing
if ($_FILES['file']['size'] > 20971520) {
    echo 'File size exceeds the maximum limit.';
    exit;
}

// Process the file upload
// Add your file upload code here
