+# PHP 8.5 — static ZTS libphp for wasix, the dependency phpix embeds. Ported from the old
+# pkgs/libraries/php (origin/php85-tailcall): upstream php-src + the php85 patch stack + bundled
+# igbinary/imagick. Built through the exnrefEh profile stdenv (wasixcc with WASM_EXCEPTIONS=yes).
+#
+# Deps go in buildInputs, so the profile stdenv auto-threads -I/-L and pkg-config (PKG_CONFIG_PATH)
+# supplies each lib's flags — the old recipe's ~25 hand-fed per-lib *_CFLAGS/*_LIBS were just
+# discovery and are gone. Only libs PHP can't find via pkg-config keep explicit flags: iconv (no
+# .pc), imagick (config.m4 patched — its .pc lookup name is wrong), pgsql + icu (explicit flags); curl's
+# full static link is derived from curl-config in configurePhase (brotli/zstd deps).
+#
+# Produces `make install-headers install-sapi` (static libphp + headers) for phpix to link via
+# passthru.phpExtraLibDirs / phpExtraLinkLibs. exnrefEh-only (passthru.wasix.supportedProfiles).
