I don't see any errors regarding this either. I have changed my code to having the curly brace before I close the file handler, if that helps any. Yet, it is still not modifying the file.

I know that some of the more recent versions of Windows, in an attempt to be more secure, make you jump through hoops to write to a file, even when the permissions are set correctly. Unfortunately, I don't have access to a system with IIS so there's no way I can test your code on that. Thanks, Ash http://www.ashleysheridan.co.uk

Well, my problem is not entirely solved, but I found that when I changed the file name extension from xml to txt, it is now letting me edit the file now.

So, this proves that it is now modifying and saving it correctly. My question is, what kind of parameter should I use to add the things I would like to add after the <messages> without editing anything else in the file. Thanks for your help.

There are two main ways to go about this: 1. Read in the entire file with file(), create a new array with your new content to insert, and splice() it back into the main array you read in at the start, then write the whole of that to the original file, overwriting anything in it. 2. Use XML functions to read in the contents of the file, add in the new nodes as you need, and overwrite the whole file again with the new DOM output Either way, you're going to have to overwrite the existing file each time.

I ended up modifying the code by using r+ instead of using a, and modified your first option by reading the file line by line and writing out the lines over again plus the edits. Finally got it solved now, and I truly appreciate it. I will probably look at simpleXML when I get a chance. Thanks for your help.
