This class can be use to access data objects in a database using PDO.

It provides a base class that should be extended by application data access classes to execute queries to store and retrieve objects in database table records.

The base class can establish database connections, execute queries and store error messages when the queries fail.

Example

<?php

require_once 'DAO.php';

// Your own class
// Tu clase propia
class UserDao extends DAO
{
    public function get_user(int $id)
    {
        // If method is executeGet(), it will return result set from database
        // Si el método es executeGet(), devolverá los datos de la base de datos
        $this->executeGet("SELECT * FROM users WHERE id = :id", ['id' => $id]);
    }
    public function save_user($name)
    {
        // Use execute() method to store data and set_msj() method to create custom message
        // Usar método execute() para insertar datos y el método set_msj() para crear un mensaje
        $this->execute("INSERT INTO users (name) VALUES (:name)", ['name' => $name]);
        $this->message("User saved successfully!");
    }
}

$user = new UserDao;

// Get user with id = 1
$user->get_user(1);

if (!$user->result['error']) {
    /* If correct, print name of user. Index 0 means get first element of array response
       Si no hay error imprimir el nombre del user
       El índice 0 indica que se obtiene el primer elemento del array de respuesta */
    echo $user->result['data'][0]['name'];
}
else {
    // If error, print error message
    // Si hay error imprimir el mensaje
    echo $user->result['data'];
}

// Close MySQL connection
// Cierra la conexión a MySQL
$user->close();
