Translation: You could save yourself all that mess and just take advantage of MySQL http://www.mysqltutorial.org/sql-union-mysql.aspx.

This is very good advice on one condition: Check out this line from the doc:

The column list of each individual SELECT statement must have the same data type.

Which I am not sure if that works in their specific instance... so union might be a total win, but might be not feasible.

JanDoToDo: could you post the clean code you wrote with array_merge_recursive, so that future readers will ignore my hideous latenight example.
