However, this is not the case, as you cannot initialize variables to constants that are defined in the same class. When trying to compile it gives an error saying the class scope is not active. However, the constant is inside the class. Also, it does not give the error where the class is defined, but when it is instantiated. So, perhaps it is an inlining error? Maybe this is what's supposed to happen, if so, then the manual needs to say that constants from the same class can't be used to initialize a var. Reproduce code: --------------- // This works: class Constants { const DEFAULT_SIZE=5; } class Square { public $size=Constants::DEFAULT_SIZE; } $r= new Square(); // this doesn't class Square2 { const DEFAULT_SIZE=5; public $size=self::DEFAULT_SIZE; } $r= new Square2(); Expected result: ---------------- I expect it to compile Actual result: -------------- PHP Fatal error: Cannot access self:: when no class scope is active in C:\src\test\consttest.php on line 23 Fatal error: Cannot access self:: when no class scope is active in C:\src\test\consttest.php on line 23 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30702&edit=1
