<title>Class Constants</title>
<para>
It is possible to define constant values on a per-class basis remaining the
same and unchangeable. Constants differ from normal variables in that you
- don't use the <varname>$</varname> symbol to declare or use them.
+ don't use the <varname>$</varname> symbol to declare or use them. Like
+ <link linkend="language.oop5.static">static</link> members, constant values
+ cannot be accessed from an instance of the object (using
+ <literal>$object::constant</literal>).
</para>
<para>
The value must be a constant expression, not (for example) a variable, a
class member, result of a mathematical operation or a function call.

- As of PHP 5.2.4, it's possible to reference the class using a variable.

Paamayim Nekudotayim would, at first, seem like a strange choice for
naming a double-colon. However, while writing the Zend Engine 0.5
(which powers PHP 3), that's what the Zend team decided to call it.
