Note that rewind($fd) is exactly the same as fseek($fd, 0, SEEK_SET)

rewind() just moves the location inside the file to the beginning, nothing more. Check if your stream is "seekable" before planning to use fseek/rewind.

As with fseek(), the rewind() function may not be used on file pointers returned by fopen() if they use the "http://" or "ftp://" formats.
