Manipulating the DOM using PHP with Uniter

Try it now


Getting started

$ npm install uniter
$ node
> var php = require('uniter').createEngine('PHP');
> php.getStdout().on('data', function (text) { console.log(text); });
> php.execute('<?php print "Hello from PHP!";');
Hello from PHP!


  • 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.

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.

Something went wrong with that request. Please try again.
