AST Optimizer & Transpiler

Optimization Pipeline

  1. PHPParser: Parses PHP source code into AST.
  2. ASTOptimizer:
    • Replaces extension_loaded("ext") calls with true or false based on engine configuration.
    • Replaces defined("CONST") with true or false.
    • Prunes if (false) branches.
    • Unwraps if (true) blocks.
  3. JSTranspiler:
    • Generates async JavaScript code using ctx.getVar(), ctx.setVar(), ctx.echo(), and await ctx.callFunction().
    • Generates source maps (.js.map).
    • Writes compiled outputs to disk cache at ${process.env.JSPHP_CACHE}/${EngineSHA1}/${FilePathSHA1}.js.
