How to declare more than one header on PHP

Question

I want to send my users to different pages based on user action. So I made multiple functions at the top of the page like so:

Answer 1

Try something like this:

<?php

$page = // use an if statement or whatever you need to figure out 
        //which page you need (pagea.php, etc.)

fnx($page)

function fnx($page) {
    header("location: " . $page);
}

?>

or

<?php

$page = // use an if statement or whatever you need to figure out 
        //which page you need (pagea.php, etc.)

header("location: " . $page);

?>

Answer 2

function one() {
     return "location: pagea.php";
}
function two() {
     return "location: pageb.php";
}
function three() {
     return "location: pagec.php";
}

header(one()); // for example

Maybe something like that?

Answer 3

Here is how i like to do when i need to send multiple headers :

$headers = array(
   'Location' => 'http://www.stackoverflow.com',
   'Content-Type' => ' application/pdf',
);

foreach ($headers as $headerType => $headerValue)
{
   header($headerType . ': ' . $headerValue);
}

Use headers_sent() to check if you'll be able to send headers or not.
