- .
+ It is possible to define constant values on a per-class basis remaining
+ the same and unchangeable. Constant's differ from normal variables
+ in that you dont use the <varname>$</varname> symbol to declare or use
+ them. Like <xref linkend="language.oop5.static"/> members, constant
+ values can not be accessed with a variable that is an instance of the
+ object.
