Yii URL

参考文章：
http://blog.csdn.net/iefreer/article/details/21325371
以http://localhost/basic/web/index.php?r=article/index为例

echo \yii\helpers\Url::base();

//输出/basic/web

echo \yii\helpers\Url::base(true)

//输出http://localhost/basic/web

//home是输出首页，加上true是输出加域名的首页

echo \yii\helpers\Url::home();

//输出/basic/web/index.php

echo\yii\helpers\Url::home(true);

//输出http:://localhost/basic/web/index.php

//当前的Url

echo \yii\helpers\Url::current();

//输出/basic/web/index.php?r=article/index

//to和toRoute都是生成Url，后面加true都是生成带域名的Url

echo \yii\helpers\Url::to([‘article/add’]);

//输出/basic/web/index.php?r=article/add

echo \yii\helpers\Url::to([‘article/edit’,’id’=>1]);

//输出/basic/web/index.php?r=article/add&id=1

echo \yii\helpers\Url::to([‘article/add’],true);

//输出http://localhost/basic/web/index.php?r=article/add

echo \yii\helpers\Url::to([‘article/edit’,’id’=>1],true);

//输出http://localhost/basic/web/index.php?r=article/add&id=1

echo\yii\helpers\Url::toRoute([‘article/add’]);

//输出/basic/web/index.php?r=article/add

echo \yii\helpers\Url::toRoute([‘article/edit’,’id’=>1]);

//输出/basic/web/index.php?r=article/add&id=1

echo \yii\helpers\Url::toRoute([‘article/add’],true);

//输出http://localhost/basic/web/index.php?r=article/add

echo\yii\helpers\Url::toRoute([‘article/edit’,’id’=>1],true);

//输出http://localhost/basic/web/index.php?r=article/add&id=1

//to和toRoute之间的区别，传入string时，to 会直接把string当成url和toRoute则会解析

echo\yii\helpers\Url::to(‘article/add’);

//输出article/add

echo\yii\helpers\Url::toRoute(‘article/add’);

//输出/basic/web/index.php?r=article/add
