In what scenarios would using the InnoDB engine over MyISAM be beneficial for PHP developers working with MySQL databases?

Using the InnoDB engine over MyISAM would be beneficial for PHP developers working with MySQL databases in scenarios where transactions and data integrity are important. InnoDB supports ACID (Atomicity, Consistency, Isolation, Durability) properties, which ensure data consistency and reliability in case of crashes or errors. In contrast, MyISAM lacks support for transactions and foreign key constraints, making it less suitable for applications that require these features. 

// Connect to MySQL database using InnoDB engine
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "mydatabase";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Set InnoDB as the default storage engine for the database
$sql = "SET default_storage_engine = 'InnoDB'";
$conn->query($sql);

$conn->close();
