The guide is for sure on the TODO, but not only - I plan to invent a tool to ease the porting process and probably a compat header. For now the simplest way to try out is using the RFC draft. There are tables with new vs. old types/macros to replace, like IS_LONG vs. IS_INT, Z_STRLEN vs. Z_STRSIZE, etc. Some of those are just semantic sugar, the others cannot be automated (like long vs. php_int_t, int vs php_size_t for string sizes ...) . From the experience many extensions will need some minimal replacements to be ported, especially those without library dependencies. The only thing I lack on an idea right now is zend_parse_parameters formats migration, I think it'll need some special way or tool to be handled. Cheers Anatol
