Hi so I am developing a registration system for a local charity's website. I am taking the data from the registration fields, adding them to an array and then writing them to a .csv file using :
I am reasonably knowledgeable about computer science but I am a fish out of water when it comes to security. I realize that proper data validation is important and I am doing this as best I can. However when it comes to actually writing to the file and storing the file what measures should I take to ensure security?
oh and btw the use of a .csv file over a mysql database is a requirement given by the client.
All help is appreciated
