I'm still new to PHP and MySQL, and I normally fumble around with 
a problem for quite a while before asking for help, but I'm trying to 
save some frustration this time.

I have a MySQL database of several thousand customers. I need to 
bring the names/addresses/etc. into an address verifyer and bulk-
mail sort program. This program does not support MySQL. I can 
successfully export the fields I need to a .csv file, and import that 
into the mail program. Once the mail program cleans the addresses, 
I can then export the now clean data into another .csv file.

Now, what's the best way to bring the now updated (cleaned) data 
back into the original MySQL database?

Should I import the data into a temporary table, and then step 
through it, record-by-record, and do an update on the original table, 
matching up the customer numbers?

Should I import the data into an array, and step through it from 
there?

Do I simply do a REPLACE where the new customer # matches the 
old customer #? There is still data in the original table that was not 
exported.

Comments, suggestions, books, and/or examples would be 
appreciated!

Thanks.
Malcolm
