Hi, i have just finished coding a design into html / css. I have spit the code up into php includes for the HEADER, NAVIGATION and the FOOTER

I have coded my navigation so that when a tab (page) is selected from navigation it has a different style. I have declared this style in the css called .selected

Can someone help me write a simple IF statement, that will work like this:

IF the current page is 'contact.php' echo '.selected' ELSE do nothing

I was hoping to past this IF statement into the code for each tab / button so it would use the .selected class if it was on that page, thanks in advance for your help...
