URL Rewriting in PHP: A Step-by-Step Guide

Implementing URL rewriting in PHP is a straightforward process that involves leveraging the capabilities of web servers and PHP frameworks. This guide will provide you with a step-by-step procedure to implement URL rewriting in your PHP application and discuss the advantages and disadvantages of different URL structures.

Step-by-Step Procedure

1. Enable mod_rewrite: Ensure that mod_rewrite is enabled on your web server.
2. Create a .htaccess file: Create a file named ".htaccess" in the web directory where you want to implement URL rewriting.

3. Add rewrite rules: Add the following rewrite rules to the .htaccess file to redirect the specified URLs:

   RewriteRule ^videos/play/([^/]+)$ videos/play.php?title= [L]
   RewriteRule ^videos/play/(\d+)/([^/]+)$ videos/play.php?id= [L]

4. Configure PHP: In your PHP script, use the $_GET superglobal to retrieve the value of the query parameters, such as $_GET['title'] and $_GET['id'].

SEO Considerations

Both URL structures mentioned in the question have their pros and cons from an SEO standpoint:

1. http://example.com/videos/play/google-io-2009-wave-intro

• Pros:

  • Keyword-rich
  • Human-readable

• Cons:

  • Poor for database management (e.g., using database tables for video metadata)

2. http://example.com/videos/play/203/google-io-2009-wave-intro

• Pros:

  • Database-friendly
  • Enables post-processing of the video (e.g., transcoding)

• Cons:

  • Not keyword-rich
  • Less intuitive for end-users

Generally, URL structure 2 is preferred for SEO as it allows for more accurate tracking and reporting. However, URL structure 1 may be more user-friendly and intuitive.
