How can PHP beginners approach the task of generating and managing files for user download on a website?

To generate and manage files for user download on a website, PHP beginners can use the header() function to set the appropriate content type and headers for file downloads. They can also use file handling functions like fopen(), fread(), and fclose() to read files from the server and output them to the user for download.

<?php
$file = 'path/to/file.pdf';

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

readfile($file);
exit;
?>
