I think it will work.
#ifdef UNDEFINED > 5 (false)
#ifdef UNDEFINED <= 5 (true)
(but anyway I think it is possible to find out an unclear condition)

Hello Dmitry, shouldn't this be like in C/C++ where a non existing value is treated like an empty string which behaves like false in boolean evaluations? marcus Friday, February 15, 2008, 11:25:42 AM, you wrote:#if defined(PHP_MAJOR_VERSION) && PHP_MAJOR_VERSION >= 6 extension="unicode.so" #endifHere PHP_MAJOR_VERSION is a PHP constant that is not defined in php-5.3 but might be defined in the future version.Dmitry.Jani Taskinen wrote:Best regards, MarcusOn Fri, 2008-02-15 at 13:02 +0300, Dmitry Stogov wrote:Jani Taskinen wrote:Why?

Then we can use just "$string" (or "$str.str") for ini entries and "string" for PHP constants. We can also implement defined() macro-function, to check if constant defined.c) We can use just "value" insted of ${value} in conditions.Yup. ${foobar} is actually not any "variable" per se, but just a reference to existing ini entry in the file. And I don't think that needs to change.
