Yii 2 框架添加.env功能，实现类似于Lavaral框架中的.env功能。使框架配置更简单，更利于维护。本项目基于yiithings/yii2-dotenv。

本项目内含2个全局调试方法: p()和dd()，替代echo()、print_r()等输出函数;

p($a, $b):打印变量，支持数组，格式化显示，不中断打印后续的输出，类似于:echo "<pre>";print_r($a);echo "----";print_r($b);
dd($a):打印变量，支持数组，格式化显示，中断打印后续的输出，类似于:echo "<pre>";print_r($A);exit()

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist indextank/yii2-plugin-env "*"

or add

"indextank/yii2-plugin-env": "*"

to the require section of your composer.json file.

Usage

Once the extension is installed, simply use it in your code by :

[
    'db' => [
        'password' => penv('DB_PASS'),
    ],
]

The env function will autoload .env file, it uses the following search mechanism:

If there is a Yii class, then pass the alias @vendor or @app or @yii, Otherwise 
according to the project directory to determine.

But, if your application vendor directory is a symbol link and you no registered @vendor or @app alias before call env function, the project will not working. So you should set the @vendor alias before calling env function.
