Propeller recording data on server

Using an ESP8266 module, I've gotten simple number graphing working on my server.

I have the propeller logging the clock value once every few seconds, creating a sawtooth plot. The program has been running for days, with fairly good accuracy. Once in a while the ESP8266 module will hang on a connection, but for the most part it's working fine.
When you bring up the page, it will only graph the points from the moment you load the page onward. However, every data entry is stored in an SQL database.
I'm working on a plotter that will allow me to view specific parts of the stored data.
I may soon change it to record sensor values instead of the clock value.

What software are you using on your website to operate the SQL database?
I'm using PHP to capture and insert the data into the database. Honestly, I could have used Python or even node, but I find that PHP seems to be "quick & easy" for most web-based things I need to work on. I was thinking about hooking up a spinnerete to capture the data, and store it on the SD.
