Navigation Higlighting using PHP

Here is a simple script that can be used to highlight an individual link on a page using PHP

Example Code

Enter the following code into a file named functions.php
<?php function getCSS($page, $normalCss, $highlightCss) { $scriptName = $_SERVER['SCRIPT_NAME']; $arr = split ("/", $scriptName); $css = $normalCss; for($i = 0; $i < count($arr); $i++) { if($arr[$i] == $page) { $css=$highlightCss; } } return $css; } ?>

Create pages named test.php, test2.php, test3.php, test4.php and enter the following code into each of them.
<?php include("functions.php"); ?> <?php include("nav.php"); ?>

Create a file named nav.php and enter the following code.
<a href="test.php" class="<?php echo (getCSS('test.php','',' select')) ?>">Test</a><br/> <a href="test2.php" class="<?php echo (getCSS('test2.php','',' select')) ?>">Test2</a> <a href="test3.php" class="<?php echo (getCSS('test3.php','',' select')) ?>">Test3</a><br/> <a href="test4.php" class="<?php echo (getCSS('test4.php','',' select')) ?>">Test4</a><br/>

Now copy all of the files to the root of your web directory and browse to test.php. Notice that the class on the "Test" link is select and the rest are blank. This is all you need to highlight an individual link on a page.
