The PHP Repl

Motivation

I simply wanted an online repl that allowed me to play with multiline php scripts. There's already a console-based repl php -a, but it and many other console-based repls are not great for multiline snippets.

Folks have even been using eval/index.php as a sandboxed, php eval script to power their own services. Pretty awesome!

Sandboxing

The online version of PHPepl is sandboxed. The exposed eval is sandboxed at the server configuration layer plus some blacklisting of methods at the application level via PHP-Sandbox.

This has, of course, crippled the tool a bit – as you can't run code that has blacklisted methods. For an unsandboxed experience, I recommend serving this app locally.

Big thanks to Elijah Horton, creator of PHP-Sandbox, for his great sandbox and assistance in maintaining PHPepl.

Running it locally

Vagrant

If you use vagrant, you can vagrant up within the phpepl root. This will spawn a virtual machine serving phpepl at the http://phpepl.dev address.

You can also do vagrant plugin install vagrant-hostsupdater if you need to fetch the hostname from /etc/hosts or another host file.

Docker

If you use Docker, you can run ./docker-bootstrap to start a container that serves the app using PHP5 and Apache.

To view the served app, visit the IP address of the host. Note, if you're using boot2docker, you need to visit the ip found via the boot2dock ip command.

Manually

To serve this application locally, you'll need any php-capable web server:

  • Mac: MAMP
  • Windows: WAMP
  • Or your own web server and php installation

Grab the source code for phpepl: fork this repo, download the source as a zip, or install via npm npm install phpepl.

You can then point your web server to serve files from the phpepl/ root folder

  • Namely, you should be able to visit the index page (phpepl/index.html) from http://localhost (include a custom port if necessary)
    • Ex: http://localhost:8000/index.html or simply http://localhost:8000, assuming your server is configured to listen to port 8000.

You'll then have free reign to execute any commands.

If you hit any errors or if someone hacked the repl and it goes down, give me a shout on Twitter: @mrjoelkemp

Close to 100 people use this REPL every day; don't ruin it for them. Please play nice.

Contribute

This app uses Browserify for bundling and Grunt for task running.

If you'd like to tinker around with the code, you can do the following:

  • Clone the repo
  • npm install in the root directory
  • grunt
  • Point your browser to your localhost (assuming you have the app being served locally)

js/phpepl.js is the main script for the website. This gets built into a hashed dist/phpepl.js which is referenced by index.html.

The php evaluation code is in eval/index.php.

That endpoint checks for the existence of a PHPEPL_PROD environment variable (which is set on the production hosts) for sandboxing. Locally, you won't have that set, so you'll have the unsandboxed version by default.

  • With grunt running, that change should rebuild the app and you can just refresh the page.
