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

Ho开发者_开发百科w 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?

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().

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();
?>
