How can PHP be optimized for efficient download speeds?

To optimize PHP for efficient download speeds, you can enable Gzip compression to reduce the size of files before they are sent to the client's browser. This can significantly decrease download times and improve overall performance. 

// Enable Gzip compression
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) {
    ob_start("ob_gzhandler");
} else {
    ob_start();
}
