dom functions multiple access to a xml file

[whisher06]

Hi.
I'm working on a rating system using
a xml file like this:

<?xml version="1.0" encoding="utf-8"?>
<poll>
<articles>
<article>
<id>2</id>
<rate>5</rate>
<rate>3</rate>
<rate>5</rate>
</article>
<article>
<id>3</id>
<rate>2</rate>
<rate>4</rate>
<rate>5</rate>
</article>
</articles>
</poll>

and I manage the file by Dom functions.

Can I have troubles if two or more users rate an articles
at the same time ?
Do you have a better xml scheda for the job ?

Bye.

You might want to implement some sort of file locking mechanism so that you don't get one script clobbering the results of a another virtually simultaneous call, such as by using the [man]flock/man function.

Thanks for the reply but with the Dom functions
I have not a handler (file pointer) to use with
flock so I have no idea to work out the trouble 🙁

The only think I can figure out is show an error
to the user if DOMDocument->save() return false

Bye.
