## What it is
V8Js is a PHP extension that embeds Google's V8 JavaScript engine into PHP, allowing execution of JavaScript code from PHP scripts. It provides a sandboxed environment with configurable time and memory limits for safely running untrusted JavaScript.

## Use cases
- run javascript from php
- execute untrusted user javascript in a sandbox
- render javascript templates server-side in a php app
- evaluate js expressions inside a php application
- share business logic between php backend and js
- sandbox third-party scripts with time and memory limits

## When to choose
- you need to execute javascript within a php application
- you must run untrusted js safely with resource limits
- you want node-like module support inside php

## When to avoid
- your stack is not php
- you need windows support
- you can use a separate node.js service instead
- you need the latest v8 features on unsupported platforms

## Facets
- artifact type: library
- maturity: maintenance
- function: interpreter, security, developer-tools
- domain: programming-languages, developer-tools, web-development
- platform: php, cpp
- tags: v8, javascript-engine, php-extension, sandbox, pecl, linux, macos
