#define for zend engine 2.1

Hello internals,

   is there a way to find out version of zend engine (2 or 2.1)?
   i need it in the code like this:

#if defined(ZEND_ENGINE_2_1)
ZEND_VM_SET_OPCODE_HANDLER(zo);
#elif defined(ZEND_ENGINE_2)
zo->handler = zend_opcode_handlers[zo->opcode];
#endif

   unfortunately, zend.h contains only these version-related defines:

#define ZEND_VERSION "2.1.0-dev"
#define ZEND_ENGINE_2
maybe, there's some other #define that can be used to tell ze2.0 from
ze2.1?

#if PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION >= 1

works ;-)

wouldn't
#if PHP_MAJOR_VERSION >= 5 && PHP_MINOR_VERSION >= 1
be better in case this code would ever be used with a hypothetical PHP
version 6? ;)

No - then it wouldn't be triggered for PHP 6.0.

no, it wouldn't. it would work with 6.1, but not with 6.0

Hello M.,

as found in SRM the correct code is:

#if (PHP_MAJOR_VERSION > 5) || (PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION >= 1)
