What are the advantages and disadvantages of closing database connections with MySQLi?

When working with MySQLi in PHP, it is important to properly close database connections to avoid potential issues such as running out of available connections or slowing down the server. While closing connections can help free up resources, it can also add overhead if connections need to be reopened frequently. It is generally recommended to close connections when they are no longer needed to ensure efficient resource management. 

// Open a connection to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Perform database operations

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