ScriptLite: An ECMAScript (ES5

ScriptLite is a sandboxed ECMAScript interpreter written in PHP that allows developers to safely embed user-provided JavaScript code for data processing, formulas, and configuration logic without exposing filesystem, network, or PHP internals. The project offers three execution backends including a C extension that runs 180x faster than the PHP VM, supporting most JavaScript features like variables, functions, arrays, and objects while intentionally excluding heavy runtime features like modules and async/await.
