Unlimited Polls no SQL Utility Script Tutorial

Website Polls utility script and tutorial using Json and Php array

Hi!. I have put together another unbelievable free php noSQL utility script just for you.
Why? Cause that is just the kind of guy I am I suppose. I work for free.
You can run unlimited polls on your websites by including the form in your page or an Iframe.
You just set your questions and options in the poll content file.

You can read the tutorial type comments in the combined script file below.
But I will here as well in order to pad the content and mansplain it here as well.

So the logic is:

You don’t need no sql baby!

Hope you like this tutorial example and find it useful! Happy Coding!
