doctrine/dbal 3.6.3

Doctrine DBAL (Database Abstraction Layer) is a powerful PHP tool for handling database operations. It provides a uniform interface for different types of databases, which allows developers to switch databases seamlessly. Furthermore, Doctrine DBAL offers a comprehensive toolkit for database schema introspection and management, making it much simpler to work with and modify your database structure.

To get started with Doctrine DBAL in your PHP project, you first need to install it using Composer:

composer require doctrine/dbal

After installation, you can initiate a database connection and start executing queries like so:

<?php
require_once 'vendor/autoload.php';

use Doctrine\DBAL\DriverManager;

$connectionParams = [
    'dbname' => 'mydb',
    'user' => 'user',
    'password' => 'secret',
    'host' => 'localhost',
    'driver' => 'pdo_mysql',
];

$conn = DriverManager::getConnection($connectionParams);

$sql = "SELECT * FROM users";
$stmt = $conn->query($sql);

while ($row = $stmt->fetch()) {
    echo $row['username']."\n";
}

In this example, the $connectionParams array holds the db connection details. The DriverManager::getConnection method establishes the connection and returns a connection object. The $conn->query($sql) method is used to execute SQL queries.

Remember, this is a basic example. You can perform more complex operations like transaction management, schema manipulation, and more with Doctrine DBAL.

Complete documentation for the Doctrine DBAL library can be found at its dedicated documentation website - DBAL Documentation. This documentation is a comprehensive guide for using Doctrine DBAL. It covers topics such as connection details, configuration settings, query builder usage, schema management, transaction operations, detailed API information, and much more. Have a look at it to get up and running with Doctrine DBAL effectively.
