I'm doing a lot of small things in PHP these days, non of them is actual web development. The environments in which these scripts are meant to run have various PHP versions installed (I'm looking at you, CentOS LTS). Since most of my tasks involve short PHP scripts it isn't worth it to fire up phpStorm and setup a whole project.
So I went to my go-to tool for small scripts: CodeRunner, but right out of the box it only supports one version at a time for PHP, since it uses the pre-installed PHP which comes with macOS High Sierra fairly outdated. You can install other PHP versions via Homebrew (package manager) but using them in parallel isn't really a pleasure. I prefer using Docker for that. And that's what we gonna do, so let's start configuring CodeRunner:
Setting up CodeRunner
- First go to the settings (
⌘;
) → Languages and search forPHP
in the list on the left. - Duplicate
PHP
with the »Settings«-Button below that list - Rename it to something meaningful, like
PHP 7.1 via Docker
- For the Run Command enter
docker run --rm -v $(pwd):/opt/project php:7.1 -f /opt/project/$filename
What this does is running a new container from the image named php:7.1
. -v $(pwd):/opt/project
mounts the current directory in which CodeRunner will run your code into /opt/project
inside of the container.
-f /opt/project/$filename
tells the php binary living inside of the container to run the script named /opt/project/$filename
.
$filename
is actually a placeholder for the filename CodeRunner will (temporarily) save your code to.
And last but not least, --rm
will ensure, that after CodeRunner executed your code, it will remove the just created container from your system again.
That has also the benefit, that every time you run your code within CodeRunner it gets executed in a fresh environment (everything you save from your code above the /opt/project
directory gets wiped)
- Close the settings window and bring the CodeRunner window to the front
- In the toolbar, there is a dropdown subtitled »Language«. Choose your newly created PHP environment labeled as
PHP 7.1 via Docker
.
Setting up Docker for Mac
Before we can start, we have to give Docker for Mac permission to mount (the -v
flag) the directory where CodeRunner places its temporary files. To do that
- Open Docker for Mac »Preferences…« via its menu item
- Go to the
File Sharing
tab and click the+
button - This will open the system open dialog. It doesn't really matter which directory you open, so you just click the »Open« button in the bottom right
- The newly create list item you have to double click. Now you can modify it
- Enter
/var/folders/pc
and press return (↩)
Bringing it all together
You're no good to go, enter something like the script below to test your newly created CodeRunner docker environment:
<?php
echo 'PHP ' . phpversion() . PHP_EOL;
When you're using the php:7.1
Docker image for the first time it needs to download it from the Docker Hub first, this can take some seconds to minutes, depending on your internet connection. It will look like the following:
Unable to find image 'php:7.1' locally
7.1: Pulling from library/php

Status: Downloaded newer image for php:7.1
And after that you'll get the output of your PHP script:
What to do next?
Congratulations, you're done and can run your short PHP scripts via Docker in CodeRunner. You can clone the PHP 7.1 via Docker
environment for other PHP versions. Right now there are several versions in the official PHP docker image, even the latest pre-release versions of PHP 7.2.
But this approach is not limited to PHP. I guess you can setup something similar for your python, node.js and ruby environments.
But there's one caveat: You have to read the corresponding Dockerfile
to find out where to set the mount point (it's probably not /opt/project
) in the image, so that when running the docker container you find your files you want to execute.

Have you tried ServBay.dev?
It's a much easier tool for PHP developers, providing a user-friendly experience, especially for beginners. It supports all versions of PHP, MariaDB, PostgreSQL, as well as Redis and Memcached. You can run multiple PHP instances simultaneously and switch between them effortlessly. It also offers easy updates without the need to configure environment variables. This tool has greatly simplified my PHP development and is definitely worth trying!
