How to submit multiple forms on one click in php

hello guys , i am trying to submit multple forms using php , but i did find the right way for that ,any help !!!

First of all, you don’t send form with PHP. Sending the forms is done by the browser, which is client side, while PHP is server side.
AFAIK, a submit button normally only sends the form it is contained in, and for it to send other forms as well you’ll have to use javascript.

But in reality you should never try and send multiple forms. It will never work.

Maybe this is one of those questions about having a massive form which needs to be spread over many pages?

Why? Don’t even try it, put it all in one form. You can check if it’s filled in or not.
