fgetcvs() 'bug', or am I stupid?

I'm using fgetcvs() to parse a CVS file - my file is structed as such: "data","data2","data3" "data","data2","data3" etc... However, fgetcvs() will always skip the first field of data on a line, except for in the first line. I've found it's because there's no comma at the end of the lines, just a newline. if I go in and put in the comma, it works perfectly. However, I can't always do this - the file gets parsed when the 'user' uploads it. The only option I see right now is to go into the file on upload and use PHP to insert a comma at the end of every line (I'm assuming that's possible). Is there any other options? Is there something wrong with my data? Am I just stupid? Thanks, Joe
