Yii gets the current URL and domain name method _php instance

The examples in this article describe how Yii obtains the current URL and domain name. Share to everyone for your reference. Specifically as follows:

Let's say the address of our current page is: http://localhost/CMS/public/index.php?r=news&id=1

One

1, get the current domain name:

Copy Code code as follows:

Echo Yii::app ()->request->hostinfo;

Result: http://localhost

2. Get the current URL (except the domain name):

Copy Code code as follows:

Echo Yii::app ()->request->geturl ();

Result:/cms/public/index.php?r=news&id=1

Copy Code code as follows:

Echo Yii::app ()->user->returnurl;

Copy Code code as follows:

Echo Yii::app ()->homeurl;

5,

Copy Code code as follows:

Echo Yii::app ()->request->baseurl;

Result:/cms/public

6, get the site root directory relative address: Echo Yii::app ()->baseurl;
Result:/cms/public (Note: If you point to the site root directly in this way, it is best to add a "/" after it, because sometimes if you do not add "/", you may not be able to correctly point to the site root directory. Application Example: <a href= "<?php Echo Yii::app ()->baseurl;? >/">Home</a>)
