What are the potential benefits and drawbacks of using sessions to prevent a PHP function from being executed multiple times?

Using sessions to prevent a PHP function from being executed multiple times can help ensure that the function is only run once per session, thus avoiding duplicate executions. However, this approach can also introduce overhead and potential conflicts if not managed properly. 

session_start();

if(!isset($_SESSION['function_executed'])){
    // Run your PHP function here
    $_SESSION['function_executed'] = true;
}
