如果不使用JavaScript，当用户在移动的中时，你不能重定向到其他页面。但是，当检测到特定的屏幕尺寸时，你可以在body标签中更改display属性，如下所示：

/* Default styles for the body */
body {
  display: block; /* or any other default value */
}

/* Media query for screens with a maximum width of 600px */
@media screen and (max-width: 600px) {
  body {
    display: none; /* or any other value for mobile screens */
  }
}

字符串
或者，如果您需要重定向到另一个页面，则必须使用JavaScript：如果移动的浏览器检测到，请在页面中使用此代码重定向到另一个URL（或页面）：

<script>
  window.mobileCheck = function () {
    let check = false;

  if (window.mobileCheck()) {
    window.location.href = "mobile.html"; // Replace this mobile.html with the page url you want to redirect
  }
</script>

型
window.mobileCheck()将检查用户是否在移动的浏览器中。然后更改windows.location.href将重定向到其他页面。（请记住将"mobile.html"替换为您想要重定向的URL/页面。）
Detecting a mobile browser的

<?php
    $iphone = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
    $android = strpos($_SERVER['HTTP_USER_AGENT'],"Android");
    $palmpre = strpos($_SERVER['HTTP_USER_AGENT'],"webOS");
    $berry = strpos($_SERVER['HTTP_USER_AGENT'],"BlackBerry");
    $ipod = strpos($_SERVER['HTTP_USER_AGENT'],"iPod");

    if ($iphone || $android || $palmpre || $ipod || $berry == true) { 
       echo "REDIRECT LINK HERE"; 
    } 
?>

字符串
只是重定向，如果你是在任何其他比手机。
