  • 判断浏览器是否是手机端

    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;

    //此条摘自TPM智能切换模板引擎,适合TPM开发
    if(isset ($_SERVER['HTTP_CLIENT']) &&'PhoneClient'==$_SERVER['HTTP_CLIENT'])
    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;
    //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;
    }
