html - Turning a <div> content into a $variable in php

Question

I have this website were you can order products.
The title of the products you can order are in HTML:

   <div class="whatever"> Title </div>

I want to retrieve this "title" and set my php variable $product to the value "Title".
I have search a lot on the internet but somehow I am not able to find my answer.
How can I do it?

Answer 1

You can use DOMDocument->loadHTML();

Ex:

<?php
$doc = new DomDocument();
$doc->loadHTML('<div class="whatever"> Title </div>');

This is assuming that your source is available to php. It would probably be more pragmatic to extract the value with javascript in the client and send it with the page request. If your app is well structured, the logic that renders the title into the page in the first place is probably where you should be looking to retrieve the information rather than trying to parse the html separately.
