Help with OOP PHP

Hello everyone,

I just started to learn OOP with PHP and I need to know what is wrong with this code please:

I am using Yii framework as well.

$testquestions = testquestions::model()->findAll(array('select'=>'*', 'condition'=>'test_id = :testid',  'params'=>array(':testid' => $testId),));

$testmodel = tests::model()->find(array('select'=>'*', 'condition'=>'test_id = :testId ', 'params'=>array(':testId' => $testId , ),));

$testquestions->question_points=$questionPoints;                                   
                            $testmodel->possible_points=$questionPoints;
                            $testmodel->save();

Code (markup):

I'm trying to get $question_points variable which is found in the column of the $testquestions table to go into the $possible_points variable which is a column in the $testmodel table.

Is the $testquestions->question_points calling the questions_points column and getting the value? if not, how do I do that?

Thank you!

 

How about

$testmodel->possible_points = $testquestions->question_points;
