yii如何判断是手机访问还是电脑访问 [ 2.0 版本 ]

composer下一个

可以使用 $_SERVER['HTTP_USER_AGENT'] 来进行判断~，然后可以继承 baseModel来封装成一个类中的判断方法~希望可以帮到你

yii框架没有的。 可以用这个 http://www.yiichina.com/tutorial/346

<?php
// These lines are mandatory.

// Alternative to magic methods.

// Find the version of component.
$detect->version('Android');

// Additional match method.
$detect->match('regex.*here');

// Browser grade method.
$detect->mobileGrade();

// Batch methods.
$detect->setUserAgent($userAgent);
$detect->setHttpHeaders($httpHeaders);
<?php

// Keep the value in $_SESSION for later use

if(!$_SESSION['isMobile']){

$_SESSION['isMobile'] = $detect->isMobile();

}

}

// Any tablet device.
if( $detect->isTablet() ){

}

// Check for a specific platform with the help of the magic methods:
if( $detect->isiOS() ){

}

if( $detect->isAndroidOS() ){

}

// Alternative method is() for checking specific properties.

foreach($userAgents as $userAgent){

$detect->setUserAgent($userAgent);
$isMobile = $detect->isMobile();
$isTablet = $detect->isTablet();
// Use the force however you want.

}

// Get the version() of components.

这个tp框架封装了的，直接复制出来用

自己写了一个方法,方法有点笨,使用了多种判断的方法,不过用起来还算是有用些,可以试一试!
