However, while the following work: php -r 'class T { const C=42; var $p=T::C; } var_dump(new T);' php -r 'class T { const C=42; const D=T::C; } var_dump(new T); the next two do not: php -r 'class T { const C=42; var $p=T::C + 1; } var_dump(new T);' php -r 'class T { const C=42; const D=T::C + 1; } var_dump(new T); So you might want to have full support for evaluated consts/default values. The reason why we do not support this right now is a limitation in how consts and default values get initialised. Best regards, Marcus
