添加多个实例

Question

So I have this code that detects what page the user is on and then spits out a class of "active" if necessary.

<li <?php if (stripos($_SERVER['REQUEST_URI'],'index.php') {echo 'class="active"';} ?>>

So just to clarify, this code checks if the url has index.php in it, and if it does, it spits out the "active" class. What I need to do and don't know how to is add multiple instances to this code. So instead of just detecting index.php it needs to be able to detect other pages like about.php for example.

Sorry if this comes a very simple question to most of you but I am new to PHP.

Split your code from the layout.

Possible solution:

   <?php 
    $active_flags = array('index.php','about.php','test.php');
    $active = '';
    foreach($active_flags as $item) {
        if(stripos($_SERVER['REQUEST_URI'],$item)!==false) {
           $active='active';
           break;
        }
    }
    ?>
   <li class="<?php echo $active?>">Your list Item</li>
