Are there any best practices to follow when implementing persistent connections in PHP?

When implementing persistent connections in PHP, it is important to properly manage the connections to prevent resource exhaustion and ensure efficient use of resources. One best practice is to use connection pooling to limit the number of connections opened at once and reuse connections whenever possible. 

// Establish a persistent connection to the database using connection pooling
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";

$connection = mysqli_connect($servername, $username, $password, $dbname, null, '/path/to/mysql/socket');
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Use the connection for database operations

// Close the connection when done
mysqli_close($connection);
