Can you tell about a case when you proposed or implemented an important improvement or innovation?

In one of my PHP projects, I noticed that the code for connecting to the database and handling errors was often repeated. I proposed implementing a wrapper class for database operations that centralizes connection, query execution, and exception handling.

This allowed:

• To reduce code duplication.
• To improve readability and maintainability.
• To detect and handle errors more quickly.

An example of a simplified class:

class Database {
    private $pdo;

    public function __construct($dsn, $user, $pass) {
        $this->pdo = new PDO($dsn, $user, $pass);
        $this->pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    }

    public function query($sql, $params = []) {
        $stmt = $this->pdo->prepare($sql);
        $stmt->execute($params);
        return $stmt->fetchAll(PDO::FETCH_ASSOC);
    }
}

This improvement increased the stability and ease of working with the database in the project.
