MySQL results in array with PHP?

Question

I generate a dynamic pdf in which one section relies on a system 'indicator' value for what it actually prints.

The system queries a member table which each member has a Type of 0,1, or 2 (thousands of rows).

At the end of the full query, I need the script to set a variable which is indicative of the whole of results returned by that type field.

For example:

• if in ANY of the type results returned there are values of 0, 1 AND 2, then set $result = 100;

• If in ANY of the type results returned, there are only values of 0 and 1, then set $result = 200;

• if in any of the type results returned, there are only values of 0, set $result = 300;

• "" there are only values of 1, set $result = 400;

• "" there are only values of 2, set $result = 500;

any good way to accomplish this?

Answer 1

You could just do a query like:

SELECT DISTINCT Type FROM Members WHERE ....

Which will return only 1 to 3 rows.

Then it's just a matter of a few ifs.

PS: you are missing the case where you have 0 and 2.
