ob_end_flush Flush (send) the output buffer and turn off output buffering boolob_end_flush This function will send the contents of the topmost output buffer (if any) and turn this output buffer off. If you want to further process the buffer's contents you have to call ob_get_contents before ob_end_flush as the buffer contents are discarded after ob_end_flush is called. The function returns &true; when it successfully discarded one buffer and &false; otherwise. Reasons for failure are first that you called the function without an active buffer or that for some reason a buffer could not be deleted (possible for special buffer). This function is similar to ob_get_flush, except that ob_get_flush returns the buffer as a string. The following example shows an easy way to flush and end all output buffers: ]]> If the function fails it generates an E_NOTICE. The boolean return value was added in PHP 4.2.0. See also ob_start, ob_get_contents, ob_get_flush, ob_flush and ob_end_clean.
