How to write a PHP script that reads a failure message?

Question

I am doing bounce-email processing with php. I have a return path in a mail function, for example:

mail ($ to_address, $ subject, $ message, $ headers, "-f". $ return_path);

$ return_path = " [e-mail] ";

Now, what should my php script look like (and where to put it) to read all the failure messages? (can show me sample code?)
