105751 storing data on .csv file

I need you to add a feature to an existing website. I need a form where the user can type his ID number. The form has to post the ID number to a php script. The script has to make a query to an oracle database to check if the ID number exists or not. If yes display a message saying "existing user" , if no the script has to store the data on a .csv file. ODBC, user & pass and fields info of the Oracle database will be sent to the winning bidder. Payment to the winning bidder will be done only trough scriptlance. So if you don´t want to get the payment trough scriptlance... please do not bid. Happy bidding.
