convert php class from php4 to php5?

[ultrus]

Hello,

I found a great little class that edits wav files. It works wonders in php 4, but draws a blank without errors when used in php 5. Any thoughts on how to give this class a face lift? Are there general items I need to look out for?

 

The class with audio samples and online examples to play with can be found here:

Thanks much for the assist.
