Wasmer PHP

Wasmer PHP is a WebAssembly runtime integration for PHP that allows developers to execute WebAssembly modules directly within PHP applications using the Wasmer runtime. It provides a native extension that exposes Wasmer’s API to PHP, closely mirroring the standard WebAssembly C API for familiarity and ease of use. The runtime is designed to execute Wasm modules at near-native speeds while maintaining strong sandboxing guarantees to ensure safety and isolation. Developers can instantiate modules, call exported functions, and interact with memory and data structures from PHP code, enabling hybrid architectures that combine PHP with high-performance compiled languages. The project is particularly useful for extending PHP applications with performance-critical logic written in languages like Rust or C that compile to WebAssembly. It also enables experimentation with portable, secure execution environments within traditional web stacks.
