yii20 custom global tool function

When we develop projects, we often use some test output methods, such as print_r(), var_dump(), etc. For these common methods, we can write a global tool function ourselves and encapsulate it uniformly. It is also convenient to use.

In Yii2.0, we can create a folder ourselves in the root directory of the project. Here we take helper as an example.

In the helper folder, create a function.php.

                            Write the following code in function.php:      

<?php

function p($var){
    echo "<pre class="brush:php;toolbar:false">";
    print_r($var);
    echo "

"; } function dd($var){ echo "

";
    var_dump($var);
    echo "

"; die; }

<span>    要是将此文件，在每个文件中引入又比较麻烦，所以，我们可以将其引入入口文件中，就可以全局使用了。</span>

<span>    在web/index.php中，添加一行，引入此文件。

<?php

namespace app\controllers;

use Yii;
use yii\web\Controller;

class TestController extends Controller
{
    function actionDatePicker(){
       return $this->render("DatePicker");
    }

    function actionIndex()
    {
        $data=[
            'name'=>'ysy',
            'age'=>'21',
        ];
        p($data);
    }

}

运行结果：

<pre class="brush:php;toolbar:false">Array
(
    [name] => ysy
    [age] => 21
)

       当然大家也可以根据自己需求，在里面写入其他的一些常用方法，加快项目开发速度。
