What is the best way to initiate a download of a zip file using PHP?

To initiate a download of a zip file using PHP, you can use the header() function to set the appropriate content type and disposition headers. This will prompt the browser to download the file instead of displaying it. You can also use readfile() function to read the contents of the zip file and output it to the browser. 

<?php
$file = 'example.zip';

header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename="' . basename($file) . '"');
header('Content-Length: ' . filesize($file));

readfile($file);
exit;
?>
