Although there are infinite ways of accomplishing this task, I usually turn to CGI variables to help with this.

For example, I'll set up a standalone php file and call it config.php...

// Set Base Path by getting the CGI script_name variable

// Remove the .php extension from the script_name variable, and set it to $file variable
$file = basename($bodyID, ".php");

// Adds class to nav items when you're on a given page
function nav_function($body_id) {
  // change scope of file so it can be used inside this function.
  global $file;
  // if the body_id and the script_name are the same, then print 'class="selected"
  if($file == $body_id) {
    print 'class="selected"';

Then, I'd include config.php before the head of my document:

<?php include('config.php'); ?>
<!doctype html>
<body id="<?php print $file; ?>">
  <ul class="nav navbar-nav navbar-right ">
    <li><a href="ourvision.php" <?php nav_function(ourvision); ?>>Our Vision</a></li> 
    <li><a href="bags.php" <?php nav_function(bags); ?>>Products</a></li>
    <li><a href="contact.php" <?php nav_function(contact); ?>>contact</a></li>

Here's a php quick start repo that I posted several months ago... Please feel free to download and tweak it as you find necessary.
