忘记在哪里获取的函数了,刚才不了心在一个包里面找到,临时保存起来

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