In the context of PHP programming, what are some common reasons why a correct answer input may not trigger the expected redirect to the correct page as described in the forum thread?

One common reason why a correct answer input may not trigger the expected redirect to the correct page is that the redirect code is not being executed properly. This could be due to errors in the conditional logic that determines when the redirect should occur, or the redirect function itself may not be functioning correctly. To solve this issue, ensure that the redirect code is placed in the correct location within the PHP script and that any conditions for the redirect are properly evaluated. 

// Example redirect code
if ($answer == "correct") {
    header("Location: correct_page.php");
    exit();
} else {
    header("Location: incorrect_page.php");
    exit();
}
