How can the user improve the PHP code to display the correct answer based on user input?

The issue with the current PHP code is that the conditional statements are not correctly checking the user input to display the correct answer. To solve this issue, we need to compare the user input with the correct answer using the '==' operator instead of the assignment operator '='. This will ensure that the correct answer is displayed based on the user input. 

<?php
$userAnswer = $_POST['answer'];

$correctAnswer = "42";

if ($userAnswer == $correctAnswer) {
    echo "Correct answer!";
} else {
    echo "Incorrect answer. The correct answer is: " . $correctAnswer;
}
?>
