How to get, in which page i posted my data in php?

Question

How do I get, from which page/url the data in the $_POST variable come from :$_SERVER['HTTP_HOST'] ?

Answer 1

You must use

$_SERVER['HTTP_REFERER']

Answer 2

The super-global $_SERVER could be useful for you, specifically $_SERVER['REQUEST_URI']:

        echo '<pre>';
        print_r($_SERVER);

//    [DOCUMENT_ROOT] => 
//    [REMOTE_ADDR] => 
//    [REMOTE_PORT] => 
//    [SERVER_SOFTWARE] => 
//    [SERVER_PROTOCOL] => 
//    [SERVER_NAME] => 
//    [SERVER_PORT] => 
//    [REQUEST_URI] => /f1 <-----------------
//    ...
