When you are testing for a property that has been added dynamically, you will need to provide a
reference to the instance rather than the class name for the first parameter.
For example, for this code snippet:
class myClass {
public $var;
}
$obj = new myClass;
$obj->new_var = "new";
var_dump(property_exists('myClass', 'new_var') );
var_dump(property_exists($obj, 'new_var') );
Returns:
boolean false
boolean true
