It is strictly procedural code.
The basic concept of the code is that it starts up, and opens a connection to
MySQL. Then using stream_socket_*() functions connects to a UDP sockets and
waits for data. Once it receives data, it figures out what the request was for.
Now, at this point, it pushed some data to MySQL, or it grabs the entire
contents of the DB tables and formats it to return to the client.
All along the way, I have debug statements that get sent to a log file in
I currently have a CPU usage time of 435hrs 20.74minutes and memory usage of
just over 6MB. Most of which is PHP itself.
