Build Status

Uniter allows you to execute PHP in the browser or in Node.js.

As an on-the-fly recompiling interpreter (or transpiler) it results in the closest possible translation from PHP to native JavaScript code.


  • Environment-agnostic architecture: should run in any modern browser (IE < 9 support coming soon) and Node.js

  • PHP statements, constructs and operators:

    • if, else and else if statements
    • while loop support
    • for loop support
    • foreach loop support
    • function statements with type hinting (as syntactic sugar only: no enforcement is performed yet)
    • Closure function expressions
    • switch statements
    • Forward and backward goto statements (but no overlap support yet)
    • class object support (new operator, extends support etc.)
    • Instance property/method access (-> operator)
    • Static class property/method access (:: operator), self:: construct
    • use statement for class, namespace and function importing and aliasing
    • Magic __autoload(...) function
    • Magic __DIR__, __FILE__ and __LINE__ constants
    • Ternary operator
    • Loose equality == and inequality != comparison operators
    • Strict equality === and inequality !== comparison operators

      And others... see the Engine integration tests for more info.

Can I try it now?

Sure you can.

Using on the command line

You can use Uniter from the command line after installing it via NPM, eg.:

# Install Uniter globally
$ npm install -g uniter

# Execute PHP code
$ uniter -r 'echo 7 + 2;'

# Parse PHP but just dump the AST as JSON, don't attempt to execute
$ uniter -r 'echo 7 + 2;' --dump-ast
    "statements": [
            "expression": {
                "left": {
                    "number": "7",
                    "name": "N_INTEGER"
                "right": [
                        "operator": "+",
                        "operand": {
                            "number": "2",
                            "name": "N_INTEGER"
                "name": "N_EXPRESSION"
            "name": "N_ECHO_STATEMENT"
    "name": "N_PROGRAM"

Keeping up to date

Running the tests

There are two supported ways of running the Mocha test suite:

  1. Run the tests in Node.js from the command line:

     cd uniter/
     npm test
  2. Run the tests in a browser by starting a Node.js server:

     npm run-script webtest

    You should then be able to run the tests by visiting in a supported web browser.
