Proper use of globals and variable scope

I am using a MVC framework and in my controller I have defined a class variable for configurations.  In my action I have a call to the configuration class to set the class variable to the current configurations.

 

public $configArray = array();

public function actionBuild($id)
{
$this->configArray=Config::model()->getConfigArray($id);

$this->buildStep1();	
...
}



 

When I echo the configuration in the method it is 10 but when I echo in buildStep1 it is 11.  What is the proper way for configArray to be global and updated when I call getConfigArray for use in functions in the class?

I changed from $this->variable_name to global declaration of the variable.  That fixed my issue.

 

as stated, this is a bad practice as it can lead to pollution down the road. Any value that your method needs should be brought in via its parameter list, not globally.
