I have a very simple app that I am working on. I have input files
containing records with a unique serial number followed by a short (<255
char) memo. The source program duplicates records from previous runs,
along with any new records. I want to create a result file w/o
duplicates. I am thinking of reading the files into an array where
serial number becomes the key and memo the value, using
array_key_exists() to filter out duplicates. The source files are no
more than a couple hundred records each, and the master should never
exceed a couple thousand.

Does anybody see any drawbacks to this, or have a better approach?

Thanks,

Bill
