Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi. I've got 2 files, an xml file and a a php script, included in another file. When the form is submitted, I want the script to insert the new line at the top of the xml, but instead it inserts the line three times. The culprit code is marked by comments.
Did you try to write $newguestbook in another file, just for testing ?
I just tried as follows:
//trouble begins here:
//var_dump($newguestbook); //this output is perfect
//but this section doesn't work as it appears it should; instead of corresponding to my var_dump it duplicates the new record three times first
//end of trouble
. . . which works as it should. But I still can't figure out why the other fails.
I don't know, I never used DOMDocument class. After a quick view in php doc, it seems it has a save method which is meant to save the xml file after making change, no ?
Maybe you have to destroy the $domguestbook object just before open the xml/guestbook.xml for writting...
$domguestbook = null;
My understanding is that saveXML just takes a dom xml tree and returns it as a string so you can write it wherever you please. But your suggestion leads to another possible solution, save(), which I've never discovered.
I tried destroying $domguestbook first, but that didn't work either. Later today I'm going to try save().
