summary

Shows that compiling the PHP interpreter with the WASI SDK into a WebAssembly module and running it with the WasmEdge runtime inside Docker Desktop produces tiny OCI images (often tens of megabytes vs hundreds of MB for Linux containers), enforces capability-based isolation (no environment variables or root filesystem access unless explicitly passed), preserves performance close to native, and runs the same module across x86/ARM/RISC-V. Demonstrations include a working PHP CLI, Docker container, Apache module path and WordPress in-browser execution.
