PHP redirect function (301 / 302)

Apr 30, 2008

I'm often asked how to do 301 redirects in PHP. It's not hard, but it's a pain having to remember the exact syntax every time. Here's a little function I wrote for Jojo CMS for making redirects easy.

Usage

Add one line of code whenever you need to do a redirect.

301 redirects...

redirect('http://www.domain.com');
or
redirect('http://www.domain.com', 301);

302 redirects...

redirect('http://www.domain.com', 302);

The function

You will need to include this code in your PHP script to be able to use this redirect function.
function redirect($url, $type=301)
{
if ($type == 301) header("HTTP/1.1 301 Moved Permanently");
header("Location: $url");
echo 'This page has moved to <a href="'.$url.'">'.$url.'</a>';
exit();
}

Jojo users

This function is available as part of Jojo CMS. Simply place "Jojo::" before the function call eg...
Jojo::redirect('http://www.domain.com');

Not so hard

There we go. A little function that makes a reasonably simple job very simple. It's saved me lots of time having to remember the exact syntax for a 301 redirect.

There's no need to remember the exact syntax every time. I always start a site with a predefined .htaccess that is saved on my email :) ... which include this:

<code>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]
</IfModule>
</code>

Hi Harvey,

I use Joomla for my website, where should I put the code in the php files? I know a little bit php and html, but not a php programmer. Can you explain it a little bit in detail?

By the way, it was very nice to meet you on Search Master siminar today. thank very much you for help!
