ob_flush

Flush (send) the output buffer

&reftitle.description; `void` `ob_flush`

This function will send the contents of the output buffer (if any). If you want to further process the buffer's contents you have to call `ob_get_contents` before `ob_flush` as the buffer contents are discarded after `ob_flush` is called.

This function does not destroy the output buffer like `ob_end_flush` does.
