ob_end_clean
(PHP 4, PHP 5)
ob_end_clean — Clean (erase) the output buffer and turn off output buffering
说明
bool ob_end_clean
( void
)
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.
返回值
如果成功则返回 TRUE,失败则返回 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).
错误/异常
If the function fails it generates an E_NOTICE.
