Advance Practical PHP | SQL (Insert, Update, Delete) - video

In this video we are talking about the super global keyword. We are using the ‘isset’ to see was set. I will check if the $_GET - SUPERGLOBAL keyword is set. This is the queryString that is sent every time you click on a button. And if it is set I want to assign it to a variable.
I am using the switch statement instead of conditional statement to perform different actions based on different conditions. I am adding some PHP just to print out the JSON data from file “data3.json”. JSON stands for “JavaScript Object Notation”.
JSON is a data-interchange format. PHP comes with a parser that is specifically written and licensed under the the PHP interpreter.
