显示php代码的自我形式动作代码

我正在开发一个关于注册的PHP代码。我开始知道自我形式的行为是安全的，而不是转到另一个形式的行动页面。当我创建表单动作时，值插入到数据库中，但我的问题是PHP代码也在上面的部分中打印。显示php代码的自我形式动作代码

这是我的PHP代码：

<?php 
     ob_start(); 
     session_start(); 
     if(isset($_SESSION['user'])!=""){ 
     header("Location: index.php"); 
     } 
    include 'dbconfig.php'; 
    $error = false; 
    extract($_POST); 
     error_reporting(0); 

    ## :: Registration :: ## 

    if(isset($_POST['submit'])) 
     { 
    $fname   = $_POST['fname']; //gets firstname from frontend 
    $lname   = $_POST['lname']; //gets lastname from frontend 
    $email   = $_POST['email']; //gets email from frontend 
    $password  = $_POST['password']; //gets password from frontend 
    $cpassword  = $_POST['cpassword']; //gets Confirm password from frontend 
    $mobile   = $_POST['mobile']; //gets mobile from frontend 
    $class   = $_POST['class']; //gets class from frontend 
    $remote   = $_SERVER['REMOTE_ADDR']; //gets the ip address from user 


$reg_query = mysqli_query($conn, "INSERT INTO `at_reg_user`(`fname`, `lname`, `email`, `password`, `cpassword`, `mobile`, `class`, `ipaddress`) VALUES ('$fname','$lname','$email','$password1','$cpassword1','$mobile','$class','$remote')"); 
     if ($reg_query) { 
    header('Location: index'); 
    $errMSG = "Successfully registered, you may login now"; 
    unset($fname); 
     unset($lname); 
    unset($email); 
    unset($password); 
    unset($cpassword); 
    unset($mobile); 
    unset($class); 

     } else { 
    $errMSG = " Not Successfully registered, you may login now"; 
    } 
} 


} 
    ?>

这是我的表单操作代码

 <form method="post" action='<?php echo htmlentities($_SERVER["PHP_SELF"]);?>' > 
    <div class="form-group"> <span class="text-danger"><?php echo $fnameError; ?></span> 
     <label class="sr-only" for="form-fname">First name</label> 
     <input type="text" name="fname" placeholder="First name..." class="form-first-name form-control" id="fname">

     <label class="sr-only" for="form-confirm-password">Confirm Password</label> 
     <input type="password" name="cpassword" placeholder="Confirm Password..." class="form-cpassword form-control" id="cpassword"> 
    </div> 
    <div class="form-group"><span class="text-danger"><?php echo $mobileError; ?></span> 
     <label class="sr-only" for="form-mobile">Mobile Number</label> 
     <input type="number" maxlength="10" name="mobile" placeholder="Mobile Number..." class="form-mobile form-control" id="mobile"> 
    </div> 
    <div class="form-group"><span class="text-danger"><?php echo $classError; ?></span> 
     <select name="class" for="form-class" class="form-class form-control id" id="class"> 
      <option selected="true" disabled="disabled">------Select Class------</option> 
      <option value="1">1</option> 
      <option value="2">2</option> 
      <option value="3">3</option> 
      <option value="4">4</option> 
      <option value="5">5</option> 
      <option value="6">6</option> 
      <option value="7">7</option> 
      <option value="8">8</option> 
      <option value="9">9</option> 
      <option value="10">10</option> 
     </select> 
    </div> 

    <button type="submit" class="btn" name="submit" id="submit">Sign me up!</button> 
</form>

对不起，但它不能理解，你需要什么。所以请用另一种方式解释 –

你应该在你的'header（）;'后面放一个'exit（）;'。这将停止脚本的进一步执行，并会阻止显示稍后在代码中发生的任何事情。同样，当你这样做时，你将不得不把你的重定向放在将数据插入数据库的代码下面 – Thakkie

来自html表单的值已经成功地插入到我的数据库中，但上面的php代码在我的html页面 – Karthik

刚删除“ob_start（）;” from the php file ..
