Downloading of PgSQL data for use local (crappy subject line)

Hello, I have: 1) PostgreSQL 7.4/8.1 2) PHP5 3) Apache 1.3 The client have 1) A web browser 2) PHP4/5 3) PostgreSQL X.XX The clients can surf my website/database and collect data for Off-Line working, exactly, I want, that they can download a file containing the requested data and importing it into there local database using a http://localhost/ Intranet Interface. Since $USER is generaly not a Geek/Nerd/Freek or something like this all must be done easyly... Now my question: What is the best format to transfer such data? I was thinking, that I create from each $ROW selected from the Database a PHP.include which contain the data in a array array[serno]="...."; array[foo]="..."; array[bar]="..."; which then can be imported and read from a PHP script. Additonaly I want to encrypt (the $USER must upload his/her public GPG key) this file because some of the "stupid" $USER can lost one (should not, but it allredy happen). Any suggestions?
