How can PHP be utilized to calculate and interpret results from a quiz or test?

To calculate and interpret results from a quiz or test using PHP, you can create an array to store the correct answers, compare the user's answers with the correct ones, and calculate the score based on the number of correct answers. 

// Array of correct answers
$correct_answers = ['A', 'B', 'C', 'D', 'A'];

// User's answers
$user_answers = ['A', 'B', 'C', 'D', 'A'];

// Calculate score
$score = 0;
for ($i = 0; $i < count($correct_answers); $i++) {
    if ($user_answers[$i] == $correct_answers[$i]) {
        $score++;
    }
}

// Interpret results
if ($score >= 3) {
    echo "Congratulations! You passed the quiz with a score of $score.";
} else {
    echo "Sorry, you did not pass the quiz. Your score is $score.";
}
