前端代碼顯示正常,為什么加入了下面的代碼,前端表單代碼就顯示不出來(lái)了?

<?php
?? ?header("Content-type:text/html;charset=utf-8");
?? ?if(isset($_REQUEST['authcode'])){
?? ??? ?session_start();

?? ??? ?if (strtolower($_REQUEST['authcode']) == $_SESSION['authcode']) {
?? ??? ??? ?echo '<font color="#0000CC">輸入正確</font>';
?? ??? ?}else{
?? ??? ??? ?echo '<font color="#CC0000"><b>輸入錯(cuò)誤</b></font>';
?? ??? ?}
?? ?}
?? ?exit();
?>
