Tell me more about your experience with PHP and projects where you applied it.

Although my main specialization is Golang, I have significant experience working with PHP, especially in web development projects and external API integration. I have created RESTful services in PHP, optimized existing code, and written unit tests.

For example, in one project, I developed a content management system where PHP was used for backend logic, form processing, and interaction with a MySQL database. I also implemented caching with Redis to improve performance.

<?php
// Example of a simple REST API in PHP
header('Content-Type: application/json');

if ($_SERVER['REQUEST_METHOD'] === 'GET') {
    echo json_encode(['status' => 'success', 'data' => 'Hello from PHP API']);
} else {
    http_response_code(405);
    echo json_encode(['error' => 'Method not allowed']);
}
?>
