试试这个

此示例仅使用"转义\，因为您已使用它来创建字符串。

<?php
session_start(); $username = $password = $userError = $passError = '';
if(isset($_POST['sub'])){
  $username = $_POST['username']; $password = $_POST['password'];
  if($username === '9155499248' && $password === 'Ben 10'){
    $_SESSION['login'] = true; header('LOCATION:congratulation.php'); die();
  }
  if($username !== '9155499248')$userError = 'Invalid Username';
  if($password !== 'Ben 10')$passError = 'Invalid Password';
}
echo "<!DOCTYPE html>
<html xmlns='http://www.w3.org/1999/xhtml' xml:lang='en' lang='en'>
   <head>
     <meta http-equiv='content-type' content='text/html;charset=utf-8' />
     <title>Login</title>
     <link rel=\"stylesheet\" href=\"css/normalize.css\">
     <link rel=\"stylesheet\" href=\"css/style.css\"/>
     <script src=\"js/prefixfree.min.js\"></script>
     </head>
 <body>
    <div class=\"login\">
<h1><b>Login</b></h1>
     <form name='input' action='{$_SERVER['PHP_SELF']}' method='post'>
    <label for='username'></label><input type='text' value='$username' id='username' name='username' />
    <div class='error'>$userError</div>
    <label for='password'></label><input type='password' value='$password' id='password' name='password' />
    <div class='error'>$passError</div>
    <button type=\"submit\" class=\"btn btn-primary btn-block btn-large\" name=\"submit\">Let me in.</button>
  </form>
  </div>
        <script src=\"js/index.js\"></script>

  </body>
