Here the blogger shared two examples of PHP judgment for everyone. One is PHP judging whether it is a mobile phone or a PC, and the other is PHP judging whether it is a WeChat browser. For your reference, the specific content is as follows
1 , Determine whether it is the mobile version

function isMobile() {
  // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
  if (isset($_SERVER[&#39;HTTP_X_WAP_PROFILE&#39;])) {    return true;
  }  // 如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
  if (isset($_SERVER[&#39;HTTP_VIA&#39;])) {    // 找不到为flase,否则为true
    return stristr($_SERVER[&#39;HTTP_VIA&#39;], "wap") ? true : false;
  }  // 脑残法，判断手机发送的客户端标志,兼容性有待提高。其中&#39;MicroMessenger&#39;是电脑微信
  if (isset($_SERVER[&#39;HTTP_USER_AGENT&#39;])) {    
  $clientkeywords = array(&#39;nokia&#39;,&#39;sony&#39;,&#39;ericsson&#39;,&#39;mot&#39;,&#39;samsung&#39;,&#39;htc&#39;,&#39;sgh&#39;,&#39;lg&#39;,&#39;sharp&#39;,&#39;sie-&#39;,&#39;philips&#39;,&#39;panasonic&#39;,&#39;alcatel&#39;,    
  &#39;lenovo&#39;,&#39;iphone&#39;,&#39;ipod&#39;,&#39;blackberry&#39;,&#39;meizu&#39;,&#39;android&#39;,&#39;netfront&#39;,&#39;symbian&#39;,&#39;ucweb&#39;,&#39;windowsce&#39;,&#39;palm&#39;,&#39;operamini&#39;,&#39;operamobi&#39;,    
  &#39;openwave&#39;,&#39;nexusone&#39;,&#39;cldc&#39;,&#39;midp&#39;,&#39;wap&#39;,&#39;mobile&#39;,&#39;MicroMessenger&#39;);    
  // 从HTTP_USER_AGENT中查找手机浏览器的关键字
    if (preg_match("/(" . implode(&#39;|&#39;, $clientkeywords) . ")/i", strtolower($_SERVER[&#39;HTTP_USER_AGENT&#39;]))) {      
    return true;
    }
  }  // 协议法，因为有可能不准确，放到最后判断
  if (isset ($_SERVER[&#39;HTTP_ACCEPT&#39;])) {    // 如果只支持wml并且不支持html那一定是移动设备
    // 如果支持wml和html但是wml在html之前则是移动设备
    if ((strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) !== false) && (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;) ===    
    false || (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) < strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;)))) {      
    return true;
    }
  }  return false;
}

2. Determine whether it is the WeChat built-in browser

function isWeixin() {
  if (strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;], &#39;MicroMessenger&#39;) !== false) {    return true;
  } else {    return false;
  }
}

Copy after login
