Highlight current item in the heading php - php

Question

So I was wondering how do you highlight the current page in the heading of the website. I used the include method to call the heading in all of the pages, but how do I highlight the current page while maintaining the include method in every page.
HEADER.PHP
<div id="site-content">
<header class="site-header">
<div class="container">
<a href="index.php" id="branding">
<img src="images/logo.png" alt="Company Name" class="logo" width="100">
<div class="branding-copy">
<h1 class="site-title" style="font-size:60px;">Benedicto Law</h1>
<small class="site-description">Justice In Words</small>
</div>
</a>
<nav class="main-navigation">
<button type="button" class="menu-toggle"><i class="fa fa-bars"></i></button>
<ul class="menu">
<li class="menu-item">Home</li>
<li class="menu-item">Attorney</li>
<li class="menu-item">Service</li>
<li class="menu-item">Contact</li>
</ul>
</nav>
<nav class="mobile-navigation"></nav>
</div>
</header> <!-- .site-header -->
then I only used
<?php include_once('header.php') ?> for calling it to other pages.
I wanted it to highlight the current menu item where the user is in.
For example:
The user pressed Attorney button the Attorney button in the heading should have a highlight.
Any help is appreciated thanks

You have at least 2 options.
1. Pass the data in PHP manually
Before your include(header statement, create a variable for the onPage and set it. Then use it in your include.
For example:
<?php
$onPage = 'attorney';
include_once('header.php') ?>
Then in header.php, check for it like this:
<li class="menu-item <?php if ($onPage == 'attorney') echo 'active'; ?>">Attorney</li>
2. Automatically detect it
In header.php
$onPage = $_SERVER['PHP_SELF'];
// make sure it's getting just the page, no directory
$onPage= explode("/",$onPage);
$onPage = $onPage[count($onPage-1)];
// remove .php and make sure its lower case
$onPage = str_replace(".php", "", strtolower($onPage));
// for /directory/Attorney.php this will give you 'attorney'
The check for it like before
<li class="menu-item <?php if ($onPage == 'attorney') echo 'active'; ?>">Attorney</li>
