External Php class in Yii?

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?

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...

Thank you. It works. EvalMath is correctly included. But now, I got another problem. Inside Yii, operations with parentheses don't work, while outside they do. Even the simple $m->evaluate('(2+2)'); breaks the program.

Solved but I don't know why that happens. Now the result has nothing when pulling the formula from the database. You can have a look to my code if you want at github.com/ivantxo/Yii-MathEval/blob/master/matheval/protected/…. The function is actionFormulas, and you will need to create a database in mysql called matheval, there is a sql script at the root of the repository. matheval.sql. thanks

class ServiceController extends Controller
{
    public function actionIndex()
    {
        Yii::import('application.controllers.back.ConsolidateController'); // ConsolidateController is another controller in back controller folder
        echo ConsolidateController::test(); // test is action in ConsolidateController
