如何从Yii2中的外部库调用变量和函数？

Question

I call to an external library in a fileForm in the models layer

namespace app\models;
use Yii;
use yii\base\Model;
include "../lib/libchart/classes/libchart.php"; //external library

However Yii2 does not recognize a variable from that external library, the error is: "PHP Fatal Error – yii\base\ErrorException - Class 'app\models\LineChart' not found"

I have the following function in the fileForm:

public function insertGrafic() {
$chart = new LineChart(); ... }

What's missing? Thanks.

Just try to add the library as a Component in your config file.

Write & use a custom Component in Yii2.0

'components' => [
    'libchart' => [
        'class' => 'class Path',
    ],

Then use your component method like this:

Yii::$app->libchart->method();
