How can the choice of database engine, like InnoDB or MyISAM, impact the performance of PHP applications?

The choice of database engine, such as InnoDB or MyISAM, can impact the performance of PHP applications due to differences in locking mechanisms, transaction support, and scalability. InnoDB is generally preferred for applications requiring ACID-compliant transactions and better concurrency control, while MyISAM may be suitable for read-heavy applications with low write operations. 

// Example of connecting to a MySQL database using InnoDB engine
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "mydatabase";

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
