Unless you have money, your "great"-fulness isn't worth much (at least not to me :-D).

What you want to do is something that a database could do easily. If you really want to do it with a file, then go back to the documentation for the file() function and read the documentation for ALL of the file functions (fread(), fwrite(), fopen(), etc.) and make the code.

It's not hard to decipher. I only help those who help themselves. Show some effort, and you'll get some assistance.

1) What have you got written so far? Posting code you are stuck with will get you better help.
2) Have you read about the explode() function

The explode() function will enable you to retreive the contents of your file into an array.

I must say that the best way to do this would be with a database. It's not difficult, read some tutroials on W3Schools and you'll be up and running in now time.

Okay, so you can't use a database, that shouldn't be a problem.

Have you tried using the explode() function I pointed out?

Try that and let me know how you get on? When you are playing around with it you may also find print_r(arrayna me) useful.

The explode function takes a string and converts it to an array, you can then print the array (print_r) to see what you've got and how you can use it best.

Have a go and post the code you get stuck on. Having a go is the best way to learn.

see i wll tell how i wnt to move abt


1st open the file in read mode
then take each line in a string using a for loop or so
then using explode searching for the : i wll split name:pradeep into 2 and then assign it some 2 variables;
and then print them in the form .
then use $_post method to read from the form and then write them to the file..

do u hve any suggstions on this

after reading from the form say $_post['name']
how to write back to file in same format as
name:pradeep

You need to try this for yourself, using the file functions referenced earlier. Have a go and post some code and the results if you run into trouble.

We are all prepared to help but we won't write the code for you.

You are not bothering us all, this is what forums are for. It's just that the best way to learn is to have a go.

This process sounds okay to me, I think you are heading down the right road with this idea. Also it's good to plan the process out before you write so full marks there.

I look forward to seeing the result. I'm sure you'll get this working as you need it to and that you will understand what you have done and why it works.
