How can PHP be optimized for performance when dealing with logging and debugging functionalities?

To optimize PHP performance when dealing with logging and debugging functionalities, it is recommended to use conditional statements to only execute logging or debugging code when necessary. This can help reduce the overhead of logging and debugging operations during normal execution of the application.

// Example of optimizing logging by using a conditional statement
if ($debugMode) {
    error_log("An error occurred: " . $errorMessage);
}
