Hello,
The question I have today is:
I have been writing data into a file from an html form where the action is performed by selecting a submit button. I thought I would get seperate entries into the file but when I try to read them out into an array it performs as though it is one big string. I am wondering why this is happening and how I can getthem to be seperate elements in an array.
Thank you.
George
