this code has some unexpected behavior:

while (OCIFetchInto($stmt,$row,OCI_RETURN_LOBS)){
  reset($formq[columns]);
  while($col=each($formq[columns])){
    $retrow[$col[value]]=$row[$col[key]];
  }
  $ret[]=$retrow;
}

if ocifetchinto returns a null into $col[x], then assigning to retrow["index"] has no effect on retrow (i.e. retrow["index"] is not instantiated... doing an each over retrow will not yeild an index "index")  I assume the expected behavior should be to instantiate retrow["index"] with an empty string.

here's my workaround:
$retrow[$col[value]]=sprintf("%s",$row[$col[key]]);

php 3.0.8 is the only non-standard module compiled into my apache server 1.3.4
