URL Rewriting in PHP with mod_rewrite and Kohana

To implement URL rewriting in your PHP application, you can leverage mod_rewrite and the Kohana framework.

Step 1: Enable mod_rewrite
Ensure that the mod_rewrite module is enabled on your web server. Typically, this can be done by editing the .htaccess file in the web directory.

Step 2: Create .htaccess File for Kohana
Add the following code to a .htaccess file in your Kohana installation directory:

# Turn on URL rewriting
RewriteEngine On

# Installation directory
RewriteBase /rootDir/

# Protect application and system files
RewriteRule ^(application|modules|system) - [F,L]

# Allow existing files to be displayed
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# Rewrite remaining URLs to index.php
RewriteRule .* index.php/<pre class="brush:php;toolbar:false"># Redirect play/google-io-2009-wave-intro
RewriteRule ^videos/play/([a-zA-Z0-9-]+)$ /videos/play.php?title= [R]

# Redirect play/203/google-io-2009-wave-intro
RewriteRule ^videos/play/([0-9]+)/([a-zA-Z0-9-]+)$ /videos/play.php?id= [R]

[PT,L]

Step 3: Redirect URLs

SEO-Friendly URL Choice
Regarding SEO, the second URL format, "http://example.com/videos/play/203/google-io-2009-wave-intro," is generally preferred due to its use of a numeric ID, which Google considers more informative. It also allows for numbered permalinks, facilitating the creation of chronological archives.
