PHP URL routing uses .htaccess for clean URLs.

Introduction to PHP URL Routing

PHP URL routing is a technique used to create clean, readable URLs that enhance user experience and improve SEO. By using .htaccess files, developers can map URL patterns to specific PHP scripts, enabling dynamic content generation based on the URL structure.

Setting Up .htaccess for URL Routing

The .htaccess file is a configuration file for Apache servers that allows developers to make server-side changes without altering the server configuration files. Here’s how you can set up URL routing using .htaccess:

Creating a PHP Router Script

Once the .htaccess file is set up to route all requests to index.php, the next step is to create a PHP script to interpret the URL and load the appropriate resources. Below is an example of a simple router script:

Dynamic Routing with Parameters

To handle dynamic routes, such as those with parameters, you need to extract parts of the URL and use them within your script. This can be done using regular expressions or by parsing the URL path.

Conclusion

PHP URL routing is a powerful technique that can significantly enhance the structure and accessibility of your web applications. By configuring .htaccess and creating a routing script, you can transform complex URLs into clean, user-friendly ones.
