Which variable is being written three times?

And where do you set the $line3 variable?

Heya, rinkudhimar.

I award 15 points for creative use of '*****' and '@@@@@' to designate code blocks.

Unfortunately, I have to deduct 15 points for failure to use [code] tags.

Better luck next time.

No.

Answer the questions I have asked you. Without that information, I don't know where to look.

$line1 and $line2 variables are being written 3 times and $line3 is of no use. I kept $line3 for IP. But now I don't want to use IP details .so discard IP($line3)

No.

Each time it goes through the while loop, it will add those lines to the file. Are you sure you want it to be in a while loop?

First of all Thanks for replying so quickly
It's necessary to put ehile loop as then and then only it will read till the end of the file. Otherwise not
