streamWrapper::stream_flush — Flushes the output
This method is called in response to fflush() and when the stream is being closed while any unflushed data has been written to it before.
If you have cached data in your stream but not yet stored it into the underlying storage, you should do so now.
此函数没有参数。
Should return TRUE
if the cached data was successfully stored (or
if there was no data to store), or FALSE
if the data could
not be stored.
Note:
If not implemented,
FALSE
is assumed as the return value.
