When working with databases in PHP, how can patterns like Active Record be utilized to streamline query execution and improve overall performance?

When working with databases in PHP, patterns like Active Record can be utilized to streamline query execution and improve overall performance by encapsulating database logic within model classes. This allows for easier manipulation of database records and reduces the need for writing complex SQL queries manually. 

// Example of implementing Active Record pattern in PHP

class User {
    private $id;
    private $username;
    private $email;

    // Constructor
    public function __construct($id, $username, $email) {
        $this->id = $id;
        $this->username = $username;
        $this->email = $email;
    }

    // Save method to insert or update user data in database
    public function save() {
        // Database connection code here
        if ($this->id) {
            // Update query
        } else {
            // Insert query
        }
    }

    // Getters and setters for class properties
    public function getId() {
        return $this->id;
    }

    public function getUsername() {
        return $this->username;
    }

    public function getEmail() {
        return $this->email;
    }

    public function setUsername($username) {
        $this->username = $username;
    }

    public function setEmail($email) {
        $this->email = $email;
    }
}

// Example usage
$user = new User(1, 'john_doe', 'john.doe@example.com');
$user->save();
