How can PHP developers streamline the process of evaluating multiple user responses in a quiz or puzzle by implementing arrays and loops effectively?

When evaluating multiple user responses in a quiz or puzzle, PHP developers can streamline the process by storing the correct answers in an array and then using a loop to compare each user response with the corresponding correct answer. This approach simplifies the code and makes it easier to manage and update the quiz or puzzle questions and answers.

// Define the correct answers in an associative array
$correctAnswers = [
    'question1' => 'answer1',
    'question2' => 'answer2',
    'question3' => 'answer3'
];

// Loop through user responses and compare with correct answers
foreach ($_POST['userResponses'] as $question => $response) {
    if ($response == $correctAnswers[$question]) {
        echo "Question $question: Correct!";
    } else {
        echo "Question $question: Incorrect. The correct answer is {$correctAnswers[$question]}.";
    }
}
