 # ---- IMPORTANT ----
 # When upgrading the Emscripten version, you will need to rebuild all the WebAssembly libraries
 # shipped in this repository before you can rebuild PHP itself. The entire build, including every
 # linked lib, must be produced by the same Emscripten version – otherwise you'll run into undefined
 # behaviors and indeterministic failures like we did in these two PRs:
