Find and replace class in php. How to implement?

Question

PHP

Hello!
In JS there is such a thing as:
$("#id1").addClass("name") (i.e. find an object with id="id1" and add class="name" to it)
Is there the same in php ?

Answer 1

I will offer phpQuery - https://habrahabr.ru/post/69149/
Unless of course I understand the question correctly.

If I were you, I would start with a deeper study of the formation of pages in php, as Stalker_RED already wrote . If the task is on fire - well, insert ajax and change through js, for example.
