   Warning

   This function is EXPERIMENTAL. The behaviour of this function, the
   name of this function, and anything else documented about this
   function may change without notice in a future release of PHP. Use
   this function at your own risk.

   dbplus_curr() will read the data for the next tuple for the given
   relation, will make it the current tuple and will pass it back as an
   associative array in tuple.

   The function will return zero (aka. DBPLUS_ERR_NOERR) on success or a
   db++ error code on failure. See dbplus_errcode() or the introduction
   to this chapter for more information on db++ error codes.

   See also dbplus_first(), dbplus_curr(), dbplus_next(), and
   dbplus_last().
