And then when the next people who want to build an alternative engine come along, they will include this constant, to make their engine as 'compatible' as possible with the current PHP engine. i.e. adding this doesn't provide a way of telling real PHP apart from something that is copying it. > Then you need to check for HHVM_VERSION So...that sounds like the correct thing to be checking for. Test for known "almost but not quite PHP" engines, otherwise assume that you're running on real PHP. cheers Dan -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
