Redirect existing url .php to new url

Question

How to redirect existing url to new url?

Sample : I have www.a.com/help.php

in google/yahoo : when visitor click this link "www.a.com/help.php" on address bar automatically change be www.a.com/help.

Because in .htaccess I was rewrite www.a.com/help and this condiction is success.

The problem is how to change automatically on address bar www.a.com/help.php --> www.a.com/help

Using .htaccess or other tricks?

Thanks.

Answer 1

You could use

<?php
header("Location: http://www.a.com/help");

That should change the addressbar.

With .htaccess you could try

redirect 301 /help.php /help
