How can reloading impact the performance of a PHP script that interacts with a MySQL server?

Reloading a PHP script that interacts with a MySQL server can impact performance by creating unnecessary connections to the database, increasing server load, and potentially causing delays in processing requests. To mitigate this issue, it's recommended to establish a persistent connection to the MySQL server using PHP's MySQLi extension. This allows the script to reuse the same connection for multiple requests, improving performance and reducing the overhead of establishing new connections. 

// Establish a persistent connection to the MySQL server
$mysqli = new mysqli('localhost', 'username', 'password', 'database', null, null, MYSQLI_CLIENT_COMPRESS);

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Perform database operations using $mysqli
