whats the difference between ob_flush and ob_end_flush?

Question

i am confused about the PHP functions ob_flush() and ob_end_flush(). About the function ob_flush the manual says

The buff         


        

Answer 1

ob_end_flush() displays everything from the buffer, then destroys the buffer. ob_flush does the same, but does not destroy the buffer just clears it.

ob_flush() =

ob_end_flush();
ob_start();
