Atom PHP Environment + CodeIgniter 3 & 4

Atom Editor


Download and install Atom Editor:

cd ~/Downloads
sudo dpkg -i atom-amd64.deb

Install required SO packages:

sudo apt install php php-sqlite3 php-mbstring sqlite3 composer npm

Code Formatters

atom-beautify uses JS Beautify by default.

sudo npm -g install js-beautify
apm install atom-beautify

For PHP, atom-beautify follow coding standards from php-codesniffer.

Install php-codesniffer:

sudo apt install php-codesniffer

After, you can see the default Standards with the command phpcs -i. The output will be like:

The installed coding standards are PEAR, Squiz, MySource, PHPCS, Zend, PSR1 and PSR2

CodeIgniter has your own Codeing Standard and the CodeIgniter-for-PHP_CodeSniffer follow this rules.

We can install the CodeIgniter Standard as follow:

mkdir CodeIgniter-for-PHP_CodeSniffer
cd CodeIgniter-for-PHP_CodeSniffer
unzip master.php

Now, lets put the src folder in the correct path:

sudo cp -r CodeIgniter-for-PHP_CodeSniffer-master/src/ /usr/share/php/PHP/CodeSniffer/Standards/CodeIgniter/

Now, the output of phpcs -i will be:

The installed coding standards are PEAR, Squiz, MySource, PHPCS, Zend, PSR1, PSR2 and CodeIgniter

If do you wnat, you can change the PHPCBF Standard to CodeIgniter.

TODO: Is possible setup PHPCBF Standard by project-manager file?


sudo npm -g install linter
sudo npm -g install htmlhint
sudo npm -g install csslint
sudo npm -g install jshint

apm install linter
apm install linter-htmlhint
apm install linter-csslint
apm install linter-jshint

The Awesome

PHP Integrator is a powerfull project that provides code analysis and utilities for PHP projects.

PHP Integrator uses composer to install the core and you need install the correct version corresponding to the php-integrator-base version.

composer global require php-integrator/core 2.1.1

PHP Integrator uses the project-manager to activate resources based by project.

Lets install the Atom packages:

apm install project-manager
apm install php-integrator-base
apm install php-integrator-linter
apm install php-integrator-annotations
apm install php-integrator-autocomplete-plus
apm install php-integrator-call-tips
apm install php-integrator-navigation
apm install php-integrator-tooltips
apm install php-integrator-refactoring


Atom CodeIgniter

When you works on a CodeIgniter 3 project you can download this file inside your project root.

After go to Atom and open the menu Packages > Project Manager > Edit Projects and configure your project like it:

  title: "CodeIgniter 3"
  paths: [
  icon: "icon-flame"
  devMode: false
    enabled: true
      enabled: true
      phpVersion: 5.6
      excludedPaths: [
      fileExtensions: [

This tip will do PHP Integrator do not read the Controller.php and Model.php from the system folder, then it will use all the @property from phpstorm.php file.

You can read more about it in Code Completion for CodeIgniter in phpStorm and here Excluding Folders From Indexing.

On CodeIgniter 4 you do not need do this config. PHP Integrator will works natively well.
