File Editing

[xianaier]

Hi,

I was wondering, how could i log on to my server, edit it a file and then upload it again?

Its going to be for my Paypal Instant Payment Notification so when they purchase my game, it goes into a file, chooses a random serial key, sends them an email with it in, then delete the serial key from that same file and then put the serial key into another file, so my register program can check if its valid.

Do you have a root access to your account? If so, then you are able to edit file on your server directly. Paypal server should call the script on your server and pass the target emial to it. Then your script reads the file with keys into array, chooses the required key, sends an email, deletes the array entry ...
