My first attempt was to use $result=array_merge($result1,$result2) - doesn't work. 'not a valid resource' I have two databases with different connections, so MySQL UNION query would not work. How do I merge the result set of the queries in that case?

You're going to have to merge the results within PHP. "not a valid resource" is an error you get when you try to read from a result set and what you pass it isn't a resource for a result set. I think you're doing something along the lines of: $result1 = query_database_one($somequery); $result2 = query_database_two($someotherquery); $result = array_merge($result1, $result2); while (mysql_fetch_row($result)) {

while reading I thought, would this: while (($row = mysql_fetch_row($result)) || ($row = mysql_fetch_row($result2))) { // just do it. √ } .. work (due to shortcircuiting)? and how ugly is it?

    // foo

}
