I recently upgraded an install of PHP Free Chat to that latest version of 1.0 Final. However it was still lacking a feature to notify individual(s) that someone has joined the chat if they were not already in the chat application to begin with. I came across a posting explaining how to achieve this in PHP Free Chat at PHP Free Chat Forum. After a little reading and discussion I was able to implement the feature.
Here’s my modified version for the solution based on the forum posting. The pfcmail() function can be made to be way more versatile for any use, however for my use it was made to be simple and produce properly formated email messages.
