PHP Sandbox

Simple and usefull tool to execute custom php scripts. It allows to block specified function to increase security.


PHP Sandbox


Clone that repository wherever you want (in my example /www/php_sandbox)

$ git clone git@github.com:plugowski/php_sandbox.git
$ cd php_sandbox

and load all dependencies via composer:

$ composer install

The final step is to run docker using docker-compose commands (of course the first step is to install docker for your environment.

$ docker-compose build
$ docker-compose up -d

Now you have working docker, go to your favourite browser and hit that addres:




Just type some code and push Evaluate button or use keyboard shortcut on Mac Command+Enter or Ctrl+Enter on Windows. More shortcuts you can find here.

Changed shortcuts by me:

Windows Mac Action
Ctrl-Enter Commantd-Enter Execute code
Ctrl-S Command-S Execute code
Alt-Shift-Up Option-Shift-Up Move lines up
Alt-Shift-Down Option-Shift-Down Move lines down
Ctrl-D Command-D Copy line
Ctrl-Shift-L Command-Shift-L Show sidebar
Ctrl-Shift-S Command-Shift-S Save Snippet
Ctrl-Shift-P Command-Shift-P Add Library / Package
