Bug description: COM does not support variant type 1 (NULL)
Currently, COM does not support variant type 1. This is type NULL.
This should be easy to fix as we can make it equivalent to false. Does PHP support null as a
constant?
The bug can be replicated by accessing a database with nulls in the records using ADO.
<?
$dbc = new COM("ADODB.Connection");
$dbc->open ("driver={Microsoft Access Driver
(*.mdb)};dbq=d:/test/DB/guestbook.mdb;uid=Admin");
$rs = $dbc->Execute("select * from guestbook");
$i = 0;
while (!$rs->EOF) {
$i += 1;
$fld0 = $rs->Fields(0);
$fld1 = $rs->Fields(1);
$fld2 = $rs->Fields(2);
print "$fld0->value $fld1->value $fld2->value<BR>";
$rs->MoveNext();
}
$rs->Close();
?>
