MySQL Connect
PHP offers multiple methods to connect to a MySQL database, each with its own features and use cases. Below are the primary methods for connecting PHP to MySQL:
1. MySQLi (MySQL Improved Extension)
MySQLi is a modern, improved extension for working with MySQL databases in PHP. It supports both procedural and object-oriented approaches.
Example - Procedural Style
Example - Object-Oriented Style
connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
Advantages of MySQLi:
- Offers both procedural and object-oriented styles.
- Allows multiple statements in a single query.
2. PDO (PHP Data Objects)
PDO is a database abstraction layer that supports multiple database types (not just MySQL). It's a great choice if your project might need to switch between databases in the future.
Example
setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
} catch (PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
?>
Advantages of PDO:
- Supports over 12 different database systems (e.g., PostgreSQL, SQLite).
- Allows easy error handling using exceptions.
