ob_end_flush

Flush (send) the output buffer and turn off output buffering

&reftitle.description; `bool` `ob_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 output buffer must be started by `ob_start` with PHP_OUTPUT_HANDLER_FLUSHABLE and PHP_OUTPUT_HANDLER_REMOVABLE flags. Otherwise `ob_end_flush` will not work.

This function is similar to `ob_get_flush`, except that `ob_get_flush` returns the buffer as a string.

&reftitle.parameters; &no.function.parameters;
&reftitle.returnvalues;

&return.success; 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).

&reftitle.errors;

If the function fails it generates an `E_NOTICE`.
