Question

Hello I need to use evalmath.class.php within a Yii application. How can I include it from my controller?

Something like this:

public function actionFormulas() {
    include('models/evalmath.class.php');
    $m = new EvalMath;
    ...
}

But the above code does not work. How can I include an external class within a controller?

Answer 1

In your example, to use include/require you probably need to add some path info with dirname(__FILE__).'/../models/...' or similar, but to do it within the Yii framework, you would first create an alias (usually in your main config file) with setPathOfAlias :

Yii::setPathOfAlias('evalmath', $evalmath_path);

Then you can use Yii::import like so:

Yii::import('evalmath', true);

and proceed as you were:

$m = new EvalMath();
..etc...
