Answer by bobdiaes for How do I use the subscriber option?

This is an old question and the PHP library ddluis linked to has many flaws.

The recommended PHP subscriber in the Google Code wiki is PuSHSubscriber:

http://github.com/lxbarth/PuSHSubscriber/

UPDATE:

I forked PuSHSubscriber: http://github.com/bobdia/PuSHSubscriber

I've made a few incompatible changes with the original. A simple implementation can be found in the /example directory. This is not meant for real use, just for demonstration purposes. I hope you find it useful.
