OUTPUT WITH EXPLANATION...

Question

<?php
$var = true?'1':false?'2':'3';
echo $var;
?>

Answer 1

Sorry, I don't know why I didn't see it, but here's the explanation:

You can look at it like this:
(true? '1': false)? '2': '3';
In the parentheses, it will be 1, which is evaluated to true, therefore the output is 2

Answer 2

THE OUTPUT IS 1. THIS CODE USES THE TERNARY OPERATOR, WHICH WORKS LIKE THIS:
condition? condition == true: condition == false;
true IS OBVIOUSLY EVALUATED TO TRUE, SO IT WILL BE THE FIRST OPTION, WHICH IS 1

Answer 3

Airree but the output is 2. Why?
