file.php?id=somevalue need redirecting to /folder/somevalue.php

Hey, after a little help here please I know its bad for SEO having duplicate pages and after flicking a few pages in to a 'Site:' search on google I've found that Google has indexed both urls so I need a permanent redirect from 'file.php?id=somevalue' to '/folder/somevalue.php' so Google will remove the duplicates from its search engine.

 

with .htaccess:

RewriteEngine On
RewriteRule ^file.php?id=(.*) folder/$1.php

with PHP:

if($_GET['somevalue']){
header("Location: folder/".$_GET['somevalue'].".php");
}

 

you must write .htaccess for this process.

You write code inside of php page.
if($_GET['url']){
header("Location: folder/".$_GET['url'].".php");
}

and you write httacess rewite module.


RewriteEngine On
RewriteRule ^file.php?id=(.*) folder/$1.php

That or make an alias directory . Then only the server knows it is one file. EVeryone else sees 2 files from 2 different directories.

 

If you want search engines to de-list the old one, a rewrite rule without any parameters -- such as that provided by @loop isn't going to do it; the page will load transparently as if it still exists! Completely missing the point

Redirect 301 ^file.php?id=(.*) folder/$1.php

Code (markup):

or

RewriteEngine On
RewriteRule ^file.php?id=(.*) folder/$1.php [L,R=301]

Code (markup):

A 301 Permanently moved on the other hand... that should do what you are asking.
