Yii 如何实现当 PC 端访问手机版的时候只会转跳到 PC 版 [ 未指定版本 ]

做个重定向不就可以了么

js就可以判断了

    把这个写在自定义的行为里边就可以了
    $pcHostInfo=Yii::$app->request->hostInfo;
	$pcAbsoluteUrl=Yii::$app->request->absoluteUrl;
	$mobileHostInfo='http://m.mobile.com';
	$mobileAbsoluteUrl=str_replace($pcHostInfo,$mobileHostInfo,$pcAbsoluteUrl);
	
	if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
	{
		return Yii::$app->response->redirect($mobileAbsoluteUrl)->send();
	}
	else if(isset($_SERVER['HTTP_VIA']))
	{
		if(stristr($_SERVER['HTTP_VIA'],"wap"))
		{
			return Yii::$app->response->redirect($mobileAbsoluteUrl)->send();
		}
		else
		{
			return true;
		}
	}
	else if(isset($_SERVER['HTTP_USER_AGENT']))
	{
		$clientkeyword=[
			'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',
		];
		
		$client=implode('|', $clientkeyword);
		
		if(preg_match("/(".$client.")/i",strtolower($_SERVER['HTTP_USER_AGENT'])))
		{
			return Yii::$app->response->redirect($mobileAbsoluteUrl)->send();
		}
		else
		{
			return true;
		}
	}
	else if(isset($_SERVER['HTTP_ACCEPT']))
	{
		$vndWapWml=strpos($_SERVER['HTTP_ACCEPT'],'vnd.wap.wml');
		$textml=strpos($_SERVER['HTTP_ACCEPT'],'textml');
		
		if(($vndWapWml!==false)&&($textml===false||($vndWapWml<$textml)))
		{
			return Yii::$app->response->redirect($mobileAbsoluteUrl)->send();
		}
		else
		{
			return true;
		}
	}
	else
	{
		return true;
	}
