What are the best practices for configuring database connections in PHP scripts for optimal performance on a Raspberry Pi?

To optimize database connections in PHP scripts on a Raspberry Pi, it is recommended to use persistent connections, limit the number of connections, and properly close connections after use to prevent resource exhaustion. 

// Establish a persistent database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$connection = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Perform database operations

// Close connection
mysqli_close($connection);
