From http://www.php.net/manual/en/language.oop5.properties.php:

"This declaration may include an initialization, but this initialization
must be a constant value--that is, it must be able to be evaluated at
compile time and must not depend on run-time information in order to be
evaluated."

From http://www.php.net/manual/en/language.oop5.constants.php: 

"The value must be a constant expression, not (for example) a variable,
a property, a result of a mathematical operation, or a function call."
