What do you mean calls arrays? Does your mysql field hold array-type data, e.g. 1,5,8,9? Do you want the result written to the mysql table? You can certainly do simple maths with just MySQL query, no need to use php, e.g.

SELECT 
myfield, IF(someotherfield <> 0,somotherfield*2,0) AS myresultfield
FROM
mytable

The above with provide a recordset with two fields: "myfield" and "myresultfield". The "myresultfield" will have a value of 0 if the field, "someotherfield" is 0, otherwise it will have a value of "someotherfield" multiplied by 2. The "myresultfield" is known as a calculated field. You can build very complex mathematical expressions and functions using MySQL.
