Growing the PHP Core One test at a Time
summary
Live-codes a real PHP core test: clones and builds PHP from GitHub, runs make test -j20, and shows runs with ~177k then ~194.5k phpt tests (99.7% passing in one run, four failures in another). Demonstrates the phpt file format, uses the environment-section to set HTTP_ACCEPT_ENCODING because copy-on-write superglobals prevent runtime mutation, and encounters ini_set header restrictions. Writes three tests for zend_get_coding_type (gzip/deflate/none), merges them into PHP, and confirms coverage moves from uncovered to covered.
