I accidentally deleted my previous post while editing his 
(just the way things are going for me now)
SO a quick rundown. I’m a complete beginner to HTML and PHP, I’m trying to post data from my Arduino over WiFi to a table on my webpage. I’m making a POST request, as you can see in my Ardunio code, to my index.php. My understanding, which is not much, is that the php code I slipped into index.php should respond to the request and store the value of “Temperature” to a variable and then echo it to the webpage at the position where I slipped in the php code.
I wanted to post data to a mySQL table and then take the data from there to post onto my webpage, but I had no luck. At this stage I just want to be able to do this basic process.
Here is a snapshot of my webpage and the table I’m trying to poste data to:

perform a simple web search.
