A field guide to writing PHP extensions
summary
Step‑by‑step reveals: scaffold an extension, run buildconf configure make and make install with clang and brew, generate arginfo from stubs, write C using zvals and the PHP function macros, add phpt tests and run them, and mind memory leaks with tools like V grind. The demo builds a PHP module that converts altimeter and QNH values, compiles and installs, tests pass and runtime calls return the expected numbers (1013 and 991).
