Keywalla PHP is a creative Locksmith Service web template built on PHP 8.1 with a clean MVC architecture, Bootstrap 4, and MySQL database integration. It ships with 20 server-rendered pages, a filterable case studies gallery, a full locks & keys shop module with cart and checkout, an appointment booking form, and a blog module, all powered by PHP with PDO database abstraction and Composer autoloading — fully ready for shared hosting deployment.

Built for PHP developers delivering locksmith, key cutting, and lock & security service websites where server-side rendering, dynamic content management, and database-backed functionality are required. The MVC structure separates routing, controllers, models, and view templates cleanly. PDO prepared statements protect every database query against SQL injection, and all user input is sanitised before output. No Node.js, no build step — deploy directly to any cPanel or Plesk host.

Everything in the Package

• 20 server-rendered PHP pages with MVC routing

MVC Architecture and File Structure

• Router: app/Router.php — maps URL paths to controller methods via regex route matching
• Controllers handle request logic and pass typed data arrays to view templates
• Models wrap PDO queries with typed return objects — swap MySQL for PostgreSQL by changing the DSN
• Views: templates/ directory with reusable partials — header.php, footer.php, navbar.php
• All user input sanitised with htmlspecialchars() before output and PDO bindings before DB queries
• CSRF tokens generated with bin2hex(random_bytes(32)) on form render, validated on POST
• Folder structure: app/Controllers/, app/Models/, app/Router.php, templates/, public/, config/, database/
