What are potential solutions for the "MySQL Server has gone away" error when using PHP to interact with a MySQL database?

The "MySQL Server has gone away" error occurs when the connection to the MySQL server is lost or timed out. To solve this issue, you can increase the `max_allowed_packet` value in your MySQL configuration file or set a longer `wait_timeout` value to keep the connection alive. 

// Increase max_allowed_packet value
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
$pdo->exec("SET GLOBAL max_allowed_packet=1073741824");

// Set a longer wait_timeout value
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
$pdo->exec("SET GLOBAL wait_timeout=3600");
