If you tired of having nasty little conditional comments like this “<!–[if lte IE 6]>…<![endif]–>” in your clean markup. Here is a quick and simple PHP function for checking what version of explorer your visitor has.

function isIE($version) {
   if ( preg_match('/MSIE (6|7)\.0/', $_SERVER['HTTP_USER_AGENT'], $ver) ) {
     if ($ver[1] == $version) return true;
   } else { 
     return false;
   }
}

And here is how you use it:

<?php if (isIE(6)): ?>
<link href="ie6.css" rel="stylesheet" type="text/css" media="screen" />
<?php endif ?>

Simply change the number to test for IE7! Now your markup doesnt have those nasty hack comment/conditional statements and you can sleep easy at night.
