# ob_flush

(PHP 4 CVS only)

ob_flush -- Flush (send) the output buffer

## Description

``void ob_flush` (void)`

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.

See also ob_get_contents(), ob_clean(), ob_end_flush() and ob_end_clean().
