Welcome to the new age porting extensions to PHP 7
summary
Porting PHP 5 extensions to PHP 7 demands concrete fixes not rhetoric: 333 functions/macros are gone, 410 are new, and 516 of 990 same‑named APIs actually change, so expect API churn. The work is to build against PHP 7, fix zend_pass_parameter type mismatches, update zval string/resource/object handling, and replace changed hash and allocator patterns. Useful tools and patterns include clang diagnostics and gdb, valgrind and CI test matrices, and a compatibility header library to smooth differences.
