XMLWriter::flush -- xmlwriter_flush — Flush current buffer
面向對象風(fēng)格
$empty = true): string|int過(guò)程化風(fēng)格

xmlwriter僅用于過(guò)程調用。被修改的 XMLWriter 實(shí)例對象。此資源來(lái)自于對 xmlwriter_open_uri() 或 xmlwriter_open_memory() 的調用。
empty
Whether to empty the buffer or not. Default is true.
If you opened the writer in memory, this function returns the generated XML buffer, Else, if using URI, this function will write the buffer and return the number of written bytes.
