It is always easy to start off with PHP using an online PHP editor instead of setting up everything on your computer. In this article, we will go through some of the best online editors you can use to compile, run, debug, and test PHP. Different editors offer different features and you might need to try out a few to decide the right fit for your requirements. 

How it all works…

Getting the final output from PHP is a two-step process where a PHP program is first compiled to the bytecode and then the bytecode is interpreted at runtime by the PHP interpreter. The engine that interprets bytecode is called Zend Engine. 

When you edit and run PHP online, you wouldn’t visibly notice the two steps since all of that happens behind the scene, you write a program, run it and see the output live in the browser.

Features of an Online PHP Editor

Going a bit back in history, offline full-featured IDEs used to be the first choice for developers for working on PHP projects. But nowadays, online editors also offer features to manage large scale enterprise-grade projects. Although, you might be looking for a very simple PHP editor just to compile some code snippets given in the tutorials, courses, or classroom assignments.

Before we get into various editors, let us briefly look at what are the key features we need in an online PHP editor – 

  • The first and foremost requirement is syntax highlighting, including code folding.
  • PHP is the language of the web, so you need support for HTML, Javascript, and CSS too. 
  • Write code and run with just one click to see output live in the browser
  • Work on the same code with fellow students or friends
  • Option to embed the code snippets in websites and blogs
  • Option to customize theme wouldn’t be bad
  • Lightweight and quick response time 
  • Option to quickly check PHP syntax online
  • Option to save, download, share code URLs
  • Creating quizzes, coding interviews, assignments
  • Code changes and version control
  • Integration with git, bitbucket, SVN, SFTP, FTP, and other third-party services
  • SQL support and connectors for databases
  • Other advanced features are available typically in commercial products. 

We will start off with a simple free PHP shell, like phpfiddle, and also cover full-featured commercial online Editors like Cloud 9 which is used for enterprise-grade project development.

9. Cloud 9

Cloud9 is the gold standard for developing enterprise-grade complex projects in the cloud while collaborating with the large remote teams. Even though Cloud9 is the cloud implementation of PHP compiler and editor, It is nothing short of offline PHP IDEs like NetBeans, PHPStrom, Zend Studio, or something like Sublime Text. 

It is worth noting that Cloud9 is now acquired by Amazon and is part of aws stack, many large organizations are fully on Cloud9 for their in-house development activities. 

The best part with Cloud9 is its seamless support for popular PHP frameworks like Laraval as well as CMS systems like WordPress and Drupal. 

You can read more about Cloud9 here at – Cloud9.


There has been a complete paradigm shift in the last few years where everyone is shifting from traditional offline editors to online editors. One key reason for that is the improved connectivity and related tools that provide collaboration among remote teams using text, audio, and video sharing. 

Furthermore, advancement and improvements in cloud infra have made sure that there is no lag in editing, compiling, and running code in the cloud. So, this brings in all the advantages of being online without losing the speed and agility that we expect from offline tools like NetBeans.
