# ob_flush

(PHP 4 >= 4.2.0, PHP 5)

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.

### Return Values

No value is returned.
