Invalid argument supplied for foreach() yii-app-basic - php

Question

I've one module -> users.
->modules
->users
->controllers
->models
->views
->Users.php
I created one 'config.php' inside 'config' folder of 'users' modules.
->modules
->users
->config
->config.php
->controllers
-> List of Controllers
->models
-> List of models
->views
-> List of Views
->Users.php
And, i gave directory path of config.php in init() method of Users.php, as
modules/users/Users.php
<?php
namespace app\modules\users;
class Users extends \yii\base\Module
{
public $controllerNamespace = 'app\modules\users\controllers';
public $commonModel = 'app\modules\users\models\Users';
public function init()
{
parent::init();
\Yii::configure($this,require(__DIR__.'/config/config.php'));
}
}
But, it is giving error like
PHP Warning – yii\base\ErrorException
"Invalid argument supplied for
foreach()".
Screenshot
I am taking reference from Yii2.0 Guide to include a path inside init() method.
Please help me to rectify this issue.
Thanks.

Answer 1

From what I can see, you're passing in the PHP code to your config file, instead of passing in a configuration array
Instead of this...
\Yii::configure($this, require(__DIR__.'/config/config.php'));
Try doing this...
$config = require(__DIR__.'/config/config.php');
\Yii::configure($this, $config);
In your config.php file you should be returning an array, if you're using the basic-app config file and adding to that then it should be set up like this already

Answer 2

The problem comes from the configuration file. The configureation file must returns an array. Make sure that the config file is as follows:
<?php
$config = [
'name1' => 'value1',
'name2' => [/* something here */],
];
return $config;

Answer 3

you edit file model and delete code:
/**
* #inheritdoc
* #return DriverSearch the active query used by this AR class.
*/
public static function find()
{
return new DriverSearch(get_called_class());
}
