i have a mysql column that looks like this: groups ------- 12,7,10,6,14,11,2 is it possible to select the row if groups contain 7 or 14? trying to avoid running two queries and running explode() on it.

I would think a more efficient strategy would be a simple string search. If you append a comma to the beginning and the end of your list so it becomes:

        ,12,7,10,6,14,11,2,

then you can search for:

        ,#,

where # is the desired integer. Therefore you could use the MySQL syntax:

        WHERE CONCAT(',', groups, ',') LIKE '%,7,%'
           OR CONCAT(',', groups, ',') LIKE '%,14,%'
