How can the separation of ob_- commands into different methods in PHP be optimized for better code structure and efficiency?

Separating ob_- commands into different methods in PHP can be optimized for better code structure and efficiency by creating individual methods for each ob_- command. This allows for better organization of code and easier maintenance. Additionally, using separate methods can improve readability and reusability of the code.

function startOutputBuffer() {
    ob_start();
}

function getOutputBuffer() {
    return ob_get_clean();
}

function flushOutputBuffer() {
    ob_end_flush();
}
