I haven't tested this code but the errors should be easy to find in a browser console. The php doesn't allow $q to be more than 5 characters to prevent injection.
Then output them as an array of three JSON objects. The extra processing to do this is negligible, even if you only use one query at a time, your script will be easier to maintain, and the JSON will separate the display from your code and make it easier to see and manage.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
