How to represent the Boolean "true" and "false" in PHP

Answer 1

// In PHP, Boolean values are represented using the built‑in literals:
// true
// false

// When printed, PHP automatically converts them to:
// true -> 1
// false -> prints nothing)

$isActive = true;   
$isFinished = false; 

echo "isActive = " . ($isActive ? "true" : "false") . "\n";
echo "isFinished = " . ($isFinished ? "true" : "false") . "\n";

// Boolean expression example
$result = (10 > 3);
echo "10 > 3 evaluates to: " . ($result ? "true" : "false") . "\n";



/*
run:

isActive = true
isFinished = false
10 > 3 evaluates to: true

*/
