Question

Thank you for dropping by.

Code

$variable = 10;
$variableOne = 10;

$result = $variable == $variableOne;
echo $result; 

When comparison between $variable and $variableOne returns false, Why is $result not assigned 0? However the end result is otherwise and $result is assigned 1 when comparison returns true.

Thank you for your time, PHP Beginner.

Answer 1

$result is assigned true or false. That's important. It's not 1 or 0, it's true or false. When echoing true, it is output as 1. When echoing false, it is output as an empty string. Try var_dump($result) instead to see the difference.
