This example describes how PHP uses Simple_html_dom to parse HTML. Share to everyone for your reference, specific as follows:

Today, I wrote two reptiles, one using Python, one using PHP, and to be honest, both implementations are convenient.

Here's an open source class that uses Simple_html_dom to parse the HTML code:

1. Download Simple_html_dom:
