Muundo if-else na Thamani Boolean

Wacha tuseme tuna badili ya boolean, ambayo inaweza kuchukua thamani true au false:

php<?php
  $test = true;
?>

Wacha tuandike if, ukikagua badili yetu ikiwa na thamani true:

php<?php
  $test = true;
  
  if ($test === true) {
    echo '+++';
  } else {
    echo '---';
  }
?>
