Doctrine DBAL (Database Abstraction Layer) is a library for database connectivity and querying in PHP. It comes with a powerful ORM (object-relational mapping) system and query builder.
The Connection class is the main entry point for using Doctrine DBAL. It establishes a connection to the database and provides all methods for querying and interacting with it. Here are some code examples:
$sql = "SELECT * FROM users WHERE id = ?"; $stmt = $conn->executeQuery($sql, array(1)); $user = $stmt->fetch();
echo $user['name'];
3. Updating database records:
$sql = "UPDATE users SET name = ? WHERE id = ?"; $stmt = $conn->executeUpdate($sql, array('John Doe', 1));
echo $stmt . ' row(s) updated.';
In these examples, we are using the Doctrine DBAL Connection class to connect to a MySQL database, query for a user record, and update a record's name field.
This library belongs to the Doctrine project and is available as a separate package called "doctrine/dbal" via Composer.
