Please help me as soon as possible

 

Friends,
I would like to be able to use fwrite to append a string to the Middle of a textfile. The only problem is, the options I have found so far only allow you to replace what is in the text file, or append to the bottom of the text file. Is there not an option to append to the middle of a text file and keep what is already present?
since i have problem to update the text file. i have one form into that form i have three text box and one buttonin first one Name in second one Password and in third one IP. i have update to the existing text file it very long. i will solve to taken an array.
