Built-in javascript interpreter for php

Question

Is there an api for embedding javascript in php - something similar to Jint for .NET.

I would like to allow the user to customize the workflow, having access to the limited php classes and methods that can be executed on the server side.

The user writes a block of code that runs later ... for example, js / ecma script code like ...

if (Contact.Age < 12){
  Contact.setEligibility = false;
}
else{
  Contact.setEligibility = true;
}
