ACK. PHP also misses a lot of other fundamental specifications (at least I'm not aware of them). That's probably one of reasons for the many problems experienced from user and enterprise operator side: sudden semantic changes. > Building your own PHP parser is _very_ hard and is PhD (Paul Biggar:) > level stuff if you wan't to get all the edge cases right. Having _the_ > official EBNF would make this easier. Hmm, perhaps it really would make a good PhD project to actually create a clear specification, a full language report (at least for the language itself and the core library) and write an tiny reference implementation. Once that specification is finished, it should become the official one where official PHP is tested against. cu -- ---------------------------------------------------------------------- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 ---------------------------------------------------------------------- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme ---------------------------------------------------------------------- -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
