(Because it's Friday???)

  Hello all,
  I'm simply trying to get a list of the field names of a layer...
  I'm using php & mapscipt 4 and accessing my MapInfo data (OGR)
  Here's my code that's not working (I get "Undefined offset" error when =
accessing the array):
  I have my results and my layer set; the result of my echo =
sizeof($flds) is 20 which is good. The item that I am querying does have =
data in all 20 fields.

                      $oRes =3D $oLayer->getResult($iRes);
                      $oShape =3D =
$oLayer->getShape(-1,$oRes->shapeindex);
                     =20
                      $flds=3D$oShape->values;
                      echo "numfields: ".sizeof($flds)."<br>";
                      for ($fieldcount=3D0; $fieldcount < sizeof($flds); =
$fieldcount++)
                          {
                             echo $flds[$fieldcount];
                          }

  should that not spit me out my field names?

  Thanks
