Quick Question on build a simple PHP app

So I've completed the the second chapter of build a simple PHP app ( creating the menu and footer ).

The part of the code that I don't understand is which part made it underlined when i was on the page.

I know that the { echo "on"; } has something to do with it, but I don't understand why it underlines it.

Any help would be awesome. Here's the code at question.

<li class="shirts <?php if ($section == "shirts") { echo "on"; } ?>"><a href="shirts.php">Shirts</a></li>

there is a css class .on where text-decoration: underline is define.

the variable $section is stocking the page name and the if condition is evaluating each link.

then php adds the class .on to the list element if condition is true.

Good response. Gave it a plus one

It's about you setting the $section variable on that page you are on, and the same code in the same header will respond to what you set that one variable too.

Take a look at your source code, and you'll see what HTML the PHP generated.
