New code testing coming to my tutorials

As part of the JavaScript tutorial on my website, I introduced testing code live on my website. Testing code was a major piece of making the tutorial work, but it was always going to be very straightforward with JavaScript and require no real security concerns since it runs in the user's browser.

Today I began to develop a way of testing both PHP and Python samples that exist on my website. I aim to have this ready by mid-March but it is slowly being rolled out across my tutorials with much of the PHP tutorial already set up for this. 

I'm hoping this will be useful and bring further benefits to using my tutorials which I'm very proud of.
