How can the use of persistent connections in PHP mitigate the occurrence of the "MySQL Server has gone away" error during database interactions?

The "MySQL Server has gone away" error commonly occurs in PHP when there is a timeout or disconnection between the PHP script and the MySQL server during database interactions. One way to mitigate this issue is by using persistent connections in PHP, which allows the connection to remain open and re-used for multiple requests, reducing the likelihood of the server timing out. 

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

// Check if the connection was successful
if ($mysqli->connect_error) {
    die('Connection failed: ' . $mysqli->connect_error);
}

// Perform database operations using the persistent connection
// For example, querying data from a table
$result = $mysqli->query("SELECT * FROM table_name");

// Close the connection when done
$mysqli->close();
