A native AOT compiler for PHP

Compile PHP source code into native machine code ahead of time — producing native executables, PHP extensions, and shared libraries — while keeping the PHP syntax you already know.

TypePHP is an Ahead-Of-Time (AOT) compiler that translates PHP source code into C++ and then into native machine code. Unlike a bytecode cache or a VM, it does not interpret opcodes at runtime: it generates optimized native binaries that run directly on the CPU.

It keeps familiar PHP syntax and adds compile-time type information, so the compiler can emit fast, statically-typed C++ for hot paths. Dynamic PHP values, internal functions, reflection, and object metadata continue to interoperate with the Zend runtime through PHPX; user functions are not executed as Zend opcodes after they have been compiled.

TypePHP is written entirely in PHP and is fully self-hosting: the tpc compiler binary is built by compiling the compiler's own PHP source code with TypePHP. The bootstrap chain is pure PHP — no C or C++ glue in the compiler itself.

TypePHP is under active development. It intentionally supports a defined, testable subset of PHP rather than claiming drop-in compatibility with every dynamic PHP program. Read Compatibility model and the incompatible-feature list before adopting it for an existing application.
