Be sure you have a proper config/main.php (this is a sample for a backend application using advanced template)
确保你有一个正确的 config/main.php（这是一个使用高级模板的后端应用程序的示例）
<?php
$params = array_merge(
require(__DIR__ . '/../../common/config/params.php'),
require(__DIR__ . '/../../common/config/params-local.php'),
require(__DIR__ . '/params.php'),
require(__DIR__ . '/params-local.php')
);
return [
'id' => 'your-app-backend',
'name' => 'Your APP Backend',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'controllerNamespace' => 'backend\controllers',
'modules' => [],
'components' => [
'log' => [
'traceLevel' => YII_DEBUG ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'errorHandler' => [
'errorAction' => 'site/error',
],
],
'params' => $params,
];
Assuming you have a param.php with
假设你有一个 param.php
<?php
return [
'adminEmail' => '[email protected]',
];
you can get the param using yii::$app->params
您可以使用 yii::$app->params 获取参数
Yii::$app->params['adminEmail'];
for printing use
印刷用
echo Yii::$app->params['adminEmail'];

You can access to one value with:
您可以通过以下方式访问一个值：
$value = Yii::$app->params['nameParameter'];
But, If you want to get the array
但是，如果你想得到数组
$values = Yii::$app->params;
You should be able to access all the properties defined in your config file which are integrated for use as "Yii::$app" attributes. In this case In this case the "params" attribute. :
您应该能够访问配置文件中定义的所有属性，这些属性被集成为用作“Yii::$app”属性。在这种情况下在这种情况下“params”属性。：
