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?
