Nothing obvious that I can see, except a little inefficiency.  Where do
$keyword and $table come from? -- is this a register_globals issue?

I'd replace all of the above with:

        $criteria = "colName like '%"
                   . str_replace(' '
                                , "%' and colName like '%"
                                , $keyword)
                   . "%'"
                   . " and col2 = '$foo' "

What's your error_reporting level?  HAve you tried cranking it up to E_ALL
to see if any relevant warnings are being generated that you're not
currently seeing?

Cheers!
