Are there specific circumstances in which it is recommended to close database connections in PHP before script termination?

It is recommended to close database connections in PHP before script termination to free up resources and prevent potential issues with database server connections becoming exhausted. This is especially important in long-running scripts or when dealing with a large number of database connections. By explicitly closing the connection, you ensure that resources are properly released and connections are not left open unnecessarily. 

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Perform database operations

// Close the database connection
$pdo = null;
