3,819 PointsHow does "status" evaluate to "thanks"?
I understand that we are searching $_GET if the status exists first, then we check to see if the "status" == "thanks". Where does "thanks" exist in the code to allow the if statement to execute? I don't understand how "status" can have a value of "thanks" if we didn't declare anything for it.

When Apache fires up PHP, when a PHP script is requested, it takes anything after a question mark, but before a hash tag, and gives it to PHP to parse. PHP parses the string by taking what is to the left of the equals sign and making that the index of the array and taking what is to the right of the equals sign and making that the value. Hope this helps.

3,819 PointsThis couldn't have been a better answer. I thought I figured it out a few minutes ago and started to move on. This answer definitely gave me a better understanding of what is actually happening. Thanks for the help!
