The new position is determined by adding the offset to the position indicated by whence. If whence is set to SEEK_SET, SEEK_CUR or SEEK_END the offset is relative to the start of the stream, the current position or the end of the stream, respectively. php_stream_seek() returns 0 on success, but -1 if there was an error. Notatka: Not all streams support seeking, although the streams API will emulate a seek if whence is set to SEEK_CUR and offset is positive, by calling php_stream_read() to read (and discard) offset bytes. The emulation is only applied when the underlying stream implementation does not support seeking. If the stream is (for example) a file based stream that is wrapping a non-seekable pipe, the streams api will not apply emulation because the file based stream implements a seek operation; the seek will fail and an error result will be returned to the caller.
