How to find all forms on the site?

Question

PHP

Guys, there is a site example.ru
It has about 500 pages. And on it you need to find all the forms for sending mail.
To do it manually is very long and there is not much time.
Do not tell me how to find all these forms.
I tried to write a php script, it didn’t work out very well (((
It’s worth linux.
Tell me a ready-made solution or can it be solved somehow
?

Answer 1

Roughly what you need is this.
This will find all the forms submitted by the post. Among them, with your eyes, you will find those that are associated with sending mail.
