Conditional Statement in PHP

1

Alright, So I’m trying to use PHP to look at the users browser and if they have IE6 or below it shows them one page and everything else is shown another.

I did an online search for the correct code but none of the browsers read the code properly:

<?php
	 
	 	if(browser_detection('browser') == 'ie6')
		{
            include 'ienavi.html';
			}
		else{
            include 'ffnavi.html';
			}
	?>
