This can be made also via jQuery or JavaScript

PHP is server side, so it will return the same thing at the same speed regardless of what computer you're on. The user can't see the code typically, so it's better for manipulating sensitive data. You would use PHP for things that happen on page load, since it can't really do much once it's served you the html.

Javascript runs on the users computer, making it reliant on their hardware and installed version. Anybody can see what you've written in Javascript with little effort. But, it is necessary for things you want to happen after the page is already loaded, such as AJAX requests to the server and animations.

For simple operations, use javascript to minimize operations on your server or php for reliability. Or just use whatever you happen to be writing in when the operation comes up.
