how can php know which html-file called it

If we have 2 html files (i.e. one.html and two.html) and within both we have a form which calls the same php file on submit, like:

<form method="post" action="example.php">

, how can example.php know which html file called it?

I'm new to php so any comments are appreciated.

There are some ways to solve this problem. It is possible to read the referer from $_SERVER['HTTP_REFERER'].

Or you set a parameter in your form to identify from where you come.

<form method="post" action="example.php?id=xy">

in your example.php you can read the $_GET['id'] and do something with a if statement or a switch.

See http://php.net/manual/en/reserved.variables.server.php

The $_SERVER['HTTP_REFERER'] variable, while not trustworthy from a security standpoint, will provide you what you want in most cases.

You could also put a hidden input in your form and pass a variable with the form name or some id that you could use.
