PHP的两边有空格，我可以'；你不能摆脱吗？

嘿，我已经用php创建了一个网页电子邮件联系人表单，然后想将其添加到原始网页中，但决定将页面中的所有html放入php文件，然后运行php文件。但两边似乎有一个奇怪的，不一致的空格，空白：0；不会删除，html中的sae代码没有任何空格（因为没有php，所以只有奇数文本）。同时，屏幕上的空白也会变得越来越小……然后再次变大，然后再次变小。我不知道为什么会这样

旁注：实际的电子邮件功能并不是完美无缺的，但我现在并不关注这一点

编辑：基本上在页面的两边都有空白，我想去掉它。边距0不起作用，我的index.php文件中的相同代码在作为HTML放入JSFIDLE时没有空格，因此我认为可能需要用另一种方式为php完成

我还注意到，当我检查它时，空格不知何故是身体的一部分

PHP:

form_process.php：

<?php 
// define variables and set to empty values
$fname_error = $lname_error = $email_error = $phone1_error = $phone2_error = $phone3_error = $message_error="";
$fname = $lname = $email = $phone1 = $phone2 = $phone3 = $message = $success = "";

//form is submitted with POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (empty($_POST["fname"])) {
    $fname_error = "Name is required";
  } else {
    $fname = test_input($_POST["fname"]);
    // check if name only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z ]*$/",$fname)) {
      $fname_error = "Only letters and white space allowed"; 
    }
  }

  if (empty($_POST["lname"])) {
    $lname_error = "Name is required";
  } else {
    $lname = test_input($_POST["lname"]);
    // check if name only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z ]*$/",$fname)) {
      $lname_error = "Only letters and white space allowed"; 
    }
  }

  if (empty($_POST["email"])) {
    $email_error = "Email is required";
  } else {
    $email = test_input($_POST["email"]);
    // check if e-mail address is well-formed
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      $email_error = "Invalid email format"; 
    }
  }

  if (empty($_POST["phone1"])) {
    $phone1_error = "required";
  } else {
    $phone1 = test_input($_POST["phone1"]);
    // check if e-mail address is well-formed

  }
  if (empty($_POST["phone2"])) {
    $phone2_error = "required";
  } else {
    $phone2 = test_input($_POST["phone2"]);
    // check if e-mail address is well-formed

  }
  if (empty($_POST["phone3"])) {
    $phone3_error = "required";
  } else {
    $phone3 = test_input($_POST["phone3"]);
    // check if e-mail address is well-formed
  }    
  if (empty($_POST["url"])) {
    $url_error = "";
  } else {
    $url = test_input($_POST["url"]);
    // check if URL address syntax is valid (this regular expression also allows dashes in the URL)
    if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$url)) {
      $url_error = "Invalid URL"; 
    }
  }

  if (empty($_POST["message"])) {
    $message_error = "Message is required";
  } else {
    $message = test_input($_POST["message"]);
  }

  if ($fname_error == '' and $lname_error == '' and $email_error == '' and $phone1_error == '' and $phone2_error == '' and $phone3_error == '' and $url_error == '' ){
      $message_body = '';
      unset($_POST['submit']);
      foreach ($_POST as $key => $value){
          $message_body .=  "$key: $value\n";
      }

      $to = 'thetalhasuboor@gmail.com';
      $subject = 'Contact Form Submit';
      if (mail($to, $subject, $message_body)){
          $success = "Message sent, thank you for contacting us!";
          $fname = $lname = $email = $phone1 = $phone2 = $phone3 = $message = $url = '';
      }
  }

}

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}

如果我理解正确，您想删除
php标记之间的空格吗？

因此，您可以尝试css代码：

.form-control {margin:0;padding:0;}

您可以尝试删除
，

也许这是有原因的
 请你详细说明一下你的问题好吗？你到底想要什么？我想去掉php文件两边的空白。所以你不想在我们的页面中使用两边间距？不，我不想使用两边间距。我想让内容从一个边缘转到另一个边缘。form_process.php的内容是什么？在浏览器中打开源代码视图并对其进行目视检查，它有时会使问题所在的位置变得明显。网页的左右两侧都有空白，我希望它从一个边缘延伸到另一个边缘。我的Imgur相册链接显示了它目前的链接。整个网页的两侧都有空白，我想去掉它，背景足够大吗？不，不是，它没有边对边，两边都有空白
