Comparing Best Code Editors for PHP Developers

This is a guest article by Stanislav Ustimenko from CodeLobster.

Since programmers spend a lot of time in their editors and IDEs, they are extremely serious about their choice of software. At a minimum, the programming environment should provide syntax checking and code correction, autocompletion and auto-addition – all known as "code intelligence." You should consider the whole aggregate of technologies used – HTML, CSS, JavaScript, PHP, as well as the distributed nature of any WEB-application.

PHP is a server programming language and, in most cases, scripts are written on one computer and run on the other, in the environment of the hosting operating system. The server part of any site may also include a huge number of SQL queries and intensive interactions with databases.

If you decide to go beyond hobby-level projects to program professionally, it is critical for your program to support the FTP protocol, understand the syntax of SQL, and provide an interface for connecting to databases, in addition to advanced editing capabilities.

Let's examine how popular code editors and IDEs implement such important capabilities for PHP developer functions.

Sublime Text

Sublime Text presents an excellent example of balance between functionality and speed, along with an economical use of system resources. The latest version works efficiently and quickly, and a reduced amount of RAM used too. It works on Windows, Linux, and Mac OS. Additionally, there is a portable version for Windows.

There is a flexible system of settings for both the interface and all kinds of functions using configuration files in JSON-format. The editor provides a set of APIs, so it can be programmed and extended using Python. There is even a built-in Python interpreter.

Immediately after starting the program, go to the main menu Tools -> Install Package Control. Package Control is a tool that allows you to manage other packages.

To expand the functionality, you have to install the packages. Start the Package Control, go to the main menu Preferences -> Package Control and enter the command Install Package from the keyboard.

Working with the code

If you open the folder with code, the editor will consider it a project.

To check the syntax of PHP when saving files, install the PHP Syntax Checker extension. Then if there are errors, a warning dialog will appear.

To highlight syntax errors on the fly, install the plug-ins SublimeLinter and SublimeLinter-php. For them to work properly, also install PHP 7.0.

Sublime text editor

Now the editor will check the file and highlight the problem line of code. You can also get information about the error in the tooltip and on the bottom panel of the editor

To get a list of links including the file with the function declaration and its use cases, simply hover the pointer on the function name.

You can also instantly go to the function declaration or class definition by right clicking on it and selecting Go to Definition from the context menu.

For those who work with frameworks and OOP, there is PHPCompanion, a special plugin  that immediately adds a whole set of useful tools to the program. This module helps to work with namespaces and import classes.

Debugging capability

Use the plugin Xdebug Client to perform full debugging with minimal settings. To work with this package, enable the Xdebug PHP extension on your server.

SQL and databases

There are two extensions for this – SQLExec and SQLTools. They share similar functionality and settings. You can also connect to PostgreSQL, MySQL, Oracle, MSSQL, SQLite, Vertica, and Firebird. You must also install a binary distribution of DB, with which you plan to interact.

Working on FTP

You’ll find it convenient to work with a remote file system using FTP, FTPS, and SFTP with the SFTP extension. It provides a very simple interface for viewing the folder structure and manipulating files.

Files are automatically uploaded to the server after saving, and there’s support for the output of information about the process of connection, downloaded, and uploaded files. All settings and actions within this plugin can be found in the menu File -> SFTP/FTP.

Support for frameworks

There is only basic support for MVC frameworks, mainly represented by various snippet collections and quick access to online documentation.


Atom is the editor the PHP community would like to know more about. Many developers who have experienced it were pleased with it – the editor is very flexibly configured, but the default settings also work well.

Atom is an open source editor, created using WEB-technologies. Extensions for Atom are created using simple JavaScript and a Node.js framework.

It is a cross-platform with versions for Mac OS, Windows, and Linux. There is also a portable version for Windows systems.

The portable version allows you not only to use the program without installation, but also to use several versions of the editor for various programming tasks simultaneously.

Working with the code

Atom allows you to open both individual files and entire directories as a project. Initially, there is basic support for PHP syntax.

This editor easily turns into a PHP IDE. To do this, install the Atom-ide-ui add-on and the specific plug-in IDE-PHP. In addition, PHP 7.0 runtime must be installed.

After applying these actions, Atom gets a more functional appearance

These add-ons provide error detection, warnings display, autocompletion and auto-addition, and improved code navigation.

Debugging capability

You can add this with extensions. For example, support for Xdebug can be enabled by installing the modules PHP-debug and Atom-debug-ui.

SQL and databases

The Data-Atom package is used to enable the support of MySQL, PostgreSQL and Microsoft SQL Server. It allows you to create connections, then view the structure of the database and tables, and perform any queries.

You will find settings and appropriate functions in the main menu Packages -> Data Atom. To properly install this plugin, Git should also be installed.

Working on FTP 

An ability to connect to a remote computer without extraneous FTP clients is achieved with the FTP-Remote-Edit package.

First, create a connection. Then you can view the contents of the remote directory, and the files will be automatically uploaded to the server after saving.

Support for frameworks

As you know, editors are not the best choice when you need to work with a lot of frameworks. However, their support can be configured by installing one or more additional packages.

Virtually, editor has extensions for various PHP frameworks, but for this software, JavaScript libraries support is better implemented.

Rapid PHP

Rapid PHP is a PHP editor with a good reputation and advanced functionality, so you could call it a lightweight IDE.

It includes the entire set of components for writing scripts in PHP and JavaScript as well as for using HTML and CSS.

There are several useful features to make it easier for novice programmers to start coding, for example, the familiar user interface, the lack of unnecessary controls and the built-in PHP interpreter.

Immediately after launching the program, you are offered a minimal user interface. Then, during the operation, you can hide and show all open panels by pressing the F4 key. There’s also an upgraded editor with PHP syntax checking, fragments insertion, highlighting search entries, and high performance when opening large files.

There is a convenient function, Goto Anything, that allows you to quickly start a search by pressing the Ctrl + G keys to go to any section of the code or file in the project.

Many useful features can be added to the editor by installing additional plug-ins. To see a list of available extensions, select the Plugins -> Manage Plugins option from the main menu.

Let's summarize

Much work was done by the developers when creating the tools discussed in this article.

As a rule, IDEs come with a lot of functionality that can’t just be selected and disabled. But it is thanks to such advanced functions that PHP programmers can get the most out of a programming environment while creating their applications and websites.

But why should an IDE lose performance with expanding functionality? At what stage of its life cycle may the development environment become "slow-moving" and inconvenience its users?

We, the CodeLobster team, tried to find an effective solution to this problem. So, we chose the low-level C++ language and the Qt library to preserve all the advantages of the native application.

As a result, the program is experiencing robust growth and we constantly add support for the new and most up-to-date WEB-frameworks. Despite the complexity of this approach and all the difficulties in maintenance of low-level code, the user experience has been greatly improved.

Because a completely cross-platform version has recently been released, you can now independently test this application on any OS.

But any editor is still a construction set. After installation, we get only the most necessary, universal capabilities. It will be necessary to install additional extensions to turn any of the editors into a full-featured IDE. But they start almost instantly, work quickly, and are not demanding on computer resources.

Which program is the best? Everyone should decide that for themselves individually.

To use a simple and fast editor or to take a full-fledged IDE – that depends on the developer her/himself, on what solutions they are seeking at the moment, and under what conditions they’re working.
