ob_start question

[johnnnn]

I've started looking into the output buffering functions in the manual, I think I sort of understand what they're user for, but I'm not 100% sure.

For example:

PHP Code:

<?php
if(is_authorized()) {
ob_start();
echo "Hello, your are logged in!";
} 

if(isSet($_GET['action']) && $_GET['action'] == 'home') {
ob_end_flush();
// some more out put here! 
}

ob_end_clean();

?>

Is that a correct way to use these functions...can someone please explain?!

Thanks! :]

Do you really need to use that function? It's not a good practice to rely much on this as it may take more resources from server. You could avoid use of it by a wise design of your system.
