How to redirect the user to a specific page with PHP? [duplicate]

You should use the header function, for example:

/** Redirecionar o usuário para /home.php: */
header('Location: /home.php');

Link to documentation .

One important note:

You can only use this function before sending any response to the client, given that it is a response header.

To learn more, consider reading this question and answer .

It is best if you create Tags for each user and check the tags, but if you want a basic thing you can use this code:

if($nome == "diego.santos" && $password == "12345"){
header('Location: id1.php');
}else if($nome == "santos.diego" && $password == "12345"){
header('Location: id2.php');
}

This is a quick example and is not a correct way to login
