bootstrap php navigation bar highlight active - php

Question

I have a problem with highlighting using php include.
Here's my navigation bar:
<?php
echo '
<link rel="stylesheet" href="css/index-css.css" type="text/css">
<link rel="stylesheet" href="css/bootstrap.min.css">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<div class="container">
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="/womsy/index.php">Womsy</a>
</div>
<ul class="nav navbar-nav">
<li <?php echo $active[1] ?>Home</li>
<li <?php echo $active[2] ?>Blog</li>
<li <?php echo $active[3] ?>Projects</li>
<li <?php echo $active[4] ?>Contact</li>
<li class="active">About</li>
</ul>
</div>
</nav>';
$active[$current] = "class=active";
?>
I made this with bootstrap, and am trying to highlight via this: http://webdevjunk.com/coding/css/17/php-menu-includes-with-css-style-to-highlight-active-page-link/
<?php
$current = 1;
include 'php/menu.php';
?>
This is what I use on the page, but it doesn't highlight, but when I change the class in the <li> it does work.
Can someone help me figure this out?

Answer 1

function setActive($pageName)
{
if (stripos($_SERVER['REQUEST_URI'], $pageName)) {
echo 'class="active"';
}
}
//$pageName will be home ,blog,projects and contacts

Answer 2

Declare page variable at the very top of each individual page.
Example: <? $page="home";?> goes at top of homepage and <? $page="blog";?> would go on top of blog page, etc.
For each list item in your menu add if statement with corresponding variable and active class.
Example: <ul><li class="<?if($page=="home"){?>active<?}?>"><b>Home</b></li><li class="<?if($page=="blog"){?>active<?}?>"><b>Blog</b></li></ul>
What this does is assign each page a variable. The variable is compared in the if statements in the nav bar to determine which li gets the active class.
