How does php identify a mobile phone or a pc?

PHP Determine whether it is a mobile phone or PC; Determine whether it is a WeChat browser; JS determine whether it is opened in a WeChat browser

1. Determine whether it is a mobile phone

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 WeChat’s 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

3. JS determine whether it is opened by a mobile device.

if (browser.versions.mobile) {//判断是否是移动设备打开。browser代码在下面
        var ua = navigator.userAgent.toLowerCase();//获取判断用的对象
        if (ua.match(/MicroMessenger/i) == "micromessenger") {
                //在微信中打开
        }
        if (ua.match(/WeiBo/i) == "weibo") {
                //在新浪微博客户端打开
        }
        if (ua.match(/QQ/i) == "qq") {
                //在QQ空间打开
        }
        if (browser.versions.ios) {
                //是否在IOS浏览器打开
        } 
        if(browser.versions.android){
                //是否在安卓浏览器打开
        }
} else {
        //否则就是PC浏览器打开
}

4. JS can determine many browsers through the following methods. Including judging IE browser, Opera browser, Safari, Google Chrome, Firefox, etc.

var browser = {
    versions: function () {
        var u = navigator.userAgent, app = navigator.appVersion;
        return {         //移动终端浏览器版本信息
            trident: u.indexOf(&#39;Trident&#39;) > -1, //IE内核
            presto: u.indexOf(&#39;Presto&#39;) > -1, //opera内核
            webKit: u.indexOf(&#39;AppleWebKit&#39;) > -1, //苹果、谷歌内核
            gecko: u.indexOf(&#39;Gecko&#39;) > -1 && u.indexOf(&#39;KHTML&#39;) == -1, //火狐内核
            mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否为移动终端
            ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端
            android: u.indexOf(&#39;Android&#39;) > -1 || u.indexOf(&#39;Linux&#39;) > -1, //android终端或uc浏览器
            iPhone: u.indexOf(&#39;iPhone&#39;) > -1, //是否为iPhone或者QQHD浏览器
            iPad: u.indexOf(&#39;iPad&#39;) > -1, //是否iPad
            webApp: u.indexOf(&#39;Safari&#39;) == -1 //是否web应该程序，没有头部与底部
        };
    }(),
    language: (navigator.browserLanguage || navigator.language).toLowerCase()
}
