php_stream_copy_to_stream -- あるストリームから別のストリームへデータをコピーする

説明

size_t php_stream_copy_to_stream ( php_stream * src, php_stream * dest, size_t maxlen)

php_stream_copy_to_stream() attempts to read up to maxlen bytes of data from src and write them to dest , and returns the number of bytes that were successfully copied.

If you want to copy all remaining data from the src stream, pass the constant PHP_STREAM_COPY_ALL as the value of maxlen .

注意 This function will attempt to copy the data in the most efficient manner, using memory mapped files when possible.
