Just a quick question. Say I have a column in my database that could contain NULLS, empty spaces, or an actual value. If I do: $my_query = "SELECT my_column FROM my_database WHERE 1 = 1"; $my_result = ifx_query($my_query, $connect_id); while($row = ifx_fetch_row($my_result)) { $my_column = trim($row['my_column']); if ($my_column != "") { echo "Test"; } } The way PHP assigns the query results to the $my_column variable, wouldn't; if ($my_column != "") not do anything for the rows that contained NULLS or empty spaces?
