如何根据PHP变量中包含的值应用CSS类？

Question

I'm using PHP, MySQL, HTML and CSS. Depending upon value in my PHP variable I want to apply a CSS class to an

element. How should I do this? My code snippet of PHP and HTMl( element) is as follows:

<?php
$e=$_POST['users']; //$e should have either employee_id or a string "All"
?>
<li><p align="center"><a href="salary_report.php">Salary Report(Individual)</a></p></li>
      <li><p align="center"><a href="salary_report_combined.php">Salary Report(Combined)</a></p></li>

Now the scenario is if $e=="All" then I have to apply a CSS class "class="active" to following

<li><p align="center"><a href="salary_report_combined.php">Salary Report(Combined)</a></p></li>

and if not then aapply the same CSS class to the other

<li><p align="center"><a href="salary_report.php">Salary Report(Individual)</a></p></li>

My issue is how should I use a condition depending upon PHP variable and apply a specific class to an HTML element? Can anyone help me in this regard? Thanks in advance.

You could do it like this:

<li class="<?php echo $e == "all" ? 'active' : ''; ?>><p align="center"><a href="salary_report_combined.php">Salary Report(Combined)</a></p></li>
