Object Constants

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$ symbol to declare or use them. Likestatic members, constant values can not be accessed from an instance of the object.

Example 18-13. Defining and using a constant

<?php
classMyClass{
  constconstant='constant value';

  functionshowConstant() {
    echo self::constant."\n";
  }
}

echoMyClass::constant."\n";

$class= newMyClass();
$class->showConstant();
/* echo $class::constant;  is not allowed */
?>
