Htaccess Revert URL Encoding

Facebook, and twitter rewri开发者_如何学Pythonte urls and replace characters(like ? or /) with code.

Original URL - http://example.com/article.php?title=hi/how-are-you?

URL after(social network redirect): http://example.com/article.php?title=hi%2Fhow-are-you%3F

I use a hosted comment system(Disqus) which uses the URL as the thread identifier, which means I will get two threads for one page because of this variation.

Is there anyway that I can revert the characters through htaccess or another method?

You could use rawurldecode.

You can get the right line back with php-function:

$_GET['title'] = urldecode($_GET['title']);

So you can pass all urls thorough some rewriter.php with this function via .htaccess. .htaccess:

    RewriteEngine on
    RewriteCond %{REQUEST_FILENAME} !-d [NC]
    RewriteCond %{REQUEST_FILENAME} !-f [NC]
    RewriteRule ^(.*)$ /rewriter.php [QSA]

rewriter.php:

<?php 
    $_GET['title'] = urldecode($_GET['title']);
    include('index.php');
?>

This method allows to use some statistics, redirects or other manipulations.
