Global Navigation With Active Selector (php)

Instead of repeating the navigation bar code in every page I want to write a single snippet of PHP code for the navigation menu bar and include that file in the relevant pages. My

Solution 1:

Check if the current script file name is part of the url that is being displayed in the navigation. If so, then assign active class to it.

foreach($items as $item) {

if(stristr($item['url'],__FILE__)===FALSE)
  {
    $html .= "<li><a href='{$item['url']}' ><span><B>{$item['text']}</B></span> </a></li>";
  }
  else
  {
    $html .= "<li class='active'><a href='{$item['url']}' ><span><B>{$item['text']}</B></span> </a></li>";
  }

}
