How can I redirect a page with a 301 header in PHP?

Question

How can I redirect

example.com/script.php?id=567

to

example.com/script2.php?id=5677&something=anotherthing&something2=anotherthing2

in php using a header 301 redirect?

Answer 1

The code itself is simple:

<?php
if($_SERVER['REQUEST_URI']=='/script.php?id=567'){
    header ('HTTP/1.1 301 Moved Permanently');
    header ('Location: http://example.com/script2.php?id=5677&something=anotherthing&something2=anotherthing2');
    die();
}
?>

You can also use $_SERVER['HTTP_HOST'] to get the hostname example.com . And you also have to make sure your script doesn't have any output before calling header() .

Answer 2

If you have access to the file script.php then you can add the following code on top:

<?php
$id = $_GET['id'];

//Get your extra params from the database if needed...

header ('HTTP/1.1 301 Moved Permanently');
header ('Location: http://example.com/script2.php?id='.$id.'&something=anotherthing&something2=anotherthing2'); //Append params retrieved from database here.
die();
?>
