15. 5 Smashing Changes
16. 1. zval
17. zval → zval** Z_*_PP() is obsolete → Change to use zval* → PHP7 frequently uses zval directly → ALLOC_ZVAL, ALLOC_INIT_ZVAL, MAKE_STD_ZVAL has removed
18. 2. char* at PHP
19. zend_string → Replacement of char* and int length → Many of PHP's API using char* has replaced to zend_string
20. 3. smart_str
21. smart_string → smart_str is only renamed to smart_string → Struct's member is also renamed
22. 4. HashTable
23. HashTable → Most API returns values, not SUCCESS, FAILURE → char*, length based API (similar to PHP5) remains → But length is changed to exclude trailing zero
24. 5. Objects
26. Conclusion → There's no best practice to upgrade extension now → Reading core extensions will help
27. Addition: interesting thing I've found #if (PHP_MAJOR_VERSION >= 6)
