[ciapug] Multi-dimensional array

[Lathrop Preston]

No problem. I do that sort of thing way more often than you might think 
would be needed...

>>As I loop through a result set I test each row, and for each row that passes, I need to record the information from 3 of the fields in the result set. Once I reach the end of my result set I need to look at the array of information, and count the number of records that had matched. Then I have a additional test I can run if I have more than one 1 row in my array. The goal is to find a 'single' match within a set of information that can in many cases have multiple results that can contain nearly exact information... Think, medical information where the only difference at times is the date on a policy, either it's active or not... or multiple policies for an individual...much of the information I have can be the same.
