Yii framework2.0 development tutorial (4) define global variables in yii

The best place to define global variables in yii is the entry script. That is, the index. php file in the web folder.

For example, after defined ('yii _ env') or define ('yii _ env', 'dev ');

Defined ('zyl _ hei') or define ('zyl _ hei', 'zhyoulun-hei ');

In the views/zhyoulun/helloworld. php file created in tutorial (1), write

<? Phpecho 'Hello world! '; // Global variable echo constant ('zyl _ hehe');?>

Http: // localhost/basic/web/index. php? R = zhyoulun/helloworld
