What is the output of the following?

<?php
echo chr((ord('a') + ord('A'))/2);
?>

Q
Correct: Q

Take the time to work this one out – it looks tiny but it still needs some attention. First we take ord('a') = 97 and ord('A') = 65, add them together (162) and then divide by 2 to make 81. Now count forwards from 65 (B is 66, C is 67, and so on) until you reach 81. The chr() function is the opposite of ord() and makes numbers back into letters.
