PHP判断是否为手机端的方法

 private 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;
        }

        //此条摘自TPM智能切换模板引擎，适合TPM开发
        if (isset($_SERVER[&#39;HTTP_CLIENT&#39;]) && &#39;PhoneClient&#39; == $_SERVER[&#39;HTTP_CLIENT&#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;], &#39;wap&#39;) ? true : false;
        }

        //判断手机发送的客户端标志,兼容性有待提高
        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;,
            );
            //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;
    }
