For example, I have a page where php and html are mixed together, and a variable is stored in the php part:

$class = "active";

In HTML I want to use this variable in the attribute of an element:

<p class="">helloworld</p>

For example, here I want to make the value of class of this p be active, which is just stored in the $class variable in php String.
what should I do then? Does JavaScript need to be used?

This is implemented in the PHP stage. It is impossible for the JavaScript code to read the value of the PHP variable.

<?php
……
$class = 'active';
……
?>
<html>
<head>……</head>
<body>
……
<p class="<?=$class?>">helloworld</p>
……
</body>
</html>
