ob_end_clean
(PHP 4, PHP 5)
ob_end_clean — Clean (erase) the output buffer and turn off output buffering
說明
This function discards the contents of the topmost output buffer and turns off this output buffering. If you want to further process the buffer's contents you have to call ob_get_contents() before ob_end_clean() as the buffer contents are discarded when ob_end_clean() is called.
Return值
如果成功則回傳 TRUE，失敗則回傳 FALSE。 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).
錯誤/例外
If the function fails it generates an E_NOTICE.
