PHP and Flash

Hi everyone,

I hope someone can shed some light on this for me!

I've just migrated a clients website over to our server. The site's
done completely in Flash, but uses a little PHP include to pull
various images from a folder and display them in the Flash movie.

Ok, this works fine on the old host, but I can't get it to work for
the life of me on my server. I've included the PHP script below. Any
feedback would be very much appreciated as I'm pulling my hair out a
bit now!

Thanks in advance,

Tom

You may want to use PHP Ming extension that lets you generate Flash
movies only with PHP code.

Here you may find an example of how to build a Image slideshow in Flash
using PHP with Ming:

I don't know Flash, never used it.

Maybe I can help here :)

What are the versions of PHP in both servers?
What are the differences between their php.ini's?

See my comments below (## lines).

## $curNode never changes (as far as I can see) in the code above.
## You're calling functions where it is a parameter, but those function
## do not declare that specific parameter (or any other) as
## pass by reference, so they get a copy of $curNode and any changes
## they make to it are lost when the function return.

## maybe
## function addFileNode($doc, &$parentNode, $fileName, $extension){
## with the ---------------- '&' here to pass by reference

## You're disregarding the return value of getFileStructure()
## This line does absolutely nothing.
