Best practices using multiple object instances?

[eluser]Unknown[/eluser]
I am pretty new to CI and faced this challenge. This is what I devised to get around this problem without any change or addon to CI.

This is an example code to create multiple instances of an object/model

Code:

foreach($_REQUEST['users'] as $userid){

    $objectName = 'u'.$userid; // each object is given a distinct name

    $this->load->model('USER', $objectName); // load the model with a distinct name

    $usersArray[] = $objectName; //store the object/model names in an array.

}

To use the object use the following code

Code:

foreach($usersArray as $theUser){

    $this->$theUser->show(); // the value of the variable '$theUser' is considered as a variable. So its like a variable inside a variable

}
