Why is it recommended to use boolean values instead of integers for representing true/false states in PHP?

Using boolean values instead of integers for representing true/false states in PHP is recommended because it makes the code more readable and easier to understand. Boolean values have only two possible states (true or false), which align perfectly with the concept of true/false conditions. This approach also helps prevent potential bugs that could arise from mistakenly using integers other than 0 and 1 to represent true/false states.

// Using boolean values to represent true/false states
$isReady = true;
if ($isReady) {
    echo "The task is ready.";
} else {
    echo "The task is not ready.";
}
