What is the best way to calculate and display quiz results in PHP, including a percentage of correct answers?

To calculate and display quiz results in PHP, including a percentage of correct answers, you can first count the total number of questions and the number of correct answers submitted by the user. Then, calculate the percentage of correct answers by dividing the number of correct answers by the total number of questions and multiplying by 100. Finally, display the results to the user. 

<?php
// Sample quiz results
$totalQuestions = 10;
$correctAnswers = 8;

// Calculate percentage of correct answers
$percentage = ($correctAnswers / $totalQuestions) * 100;

// Display quiz results
echo "You answered $correctAnswers out of $totalQuestions questions correctly.<br>";
echo "Your score is: $percentage%";
?>
