I would like to correct the above documentation.  I am able to get results from ora_numcols after a parse & exec sequence and before a fetch:


ora_parse($curs,$query);


ora_exec($curs);





$numfields = ora_numcols($curs);





for($col=0;$col<$numfields;$col++){


  echo ora_columnname($curs,$col);


}


while(ora_fetch($curs)){


etc.........................


}
