What are common methods for highlighting the current step in a PHP form navigation system?

One common method for highlighting the current step in a PHP form navigation system is to use a combination of HTML and PHP to dynamically add a CSS class to the current step link. This can be achieved by checking the current step against the step number in the navigation menu and applying a specific class to the corresponding link. 

```php
<ul>
    <li<?php echo ($currentStep == 1) ? ' class="active"' : ''; ?>><a href="step1.php">Step 1</a></li>
    <li<?php echo ($currentStep == 2) ? ' class="active"' : ''; ?>><a href="step2.php">Step 2</a></li>
    <li<?php echo ($currentStep == 3) ? ' class="active"' : ''; ?>><a href="step3.php">Step 3</a></li>
</ul>
```

In this code snippet, the `$currentStep` variable represents the current step in the form navigation system. The `active` class is conditionally added to the `<li>` element of the current step link based on the comparison with the `$currentStep` variable. This allows for visual highlighting of the current step in the navigation menu.
