How to set titles for php links?

Question

PHP

They asked for some help with optimizing the site. You need to write titles, and links to categories are loaded from the php file and look like "uslugi.php?categories=Repair%20mobile%20phones" - accordingly, they inherit the title from the "uslugi.php" page. Site fixall.com.ua

Or write a banal switch case and wind up your own unique title.
