Phalcon Framework

Build Status Windows Build Phalcon Backers OpenCollective OpenCollective

Phalcon is an open source web framework delivered as a C extension for the PHP language providing high performance and lower resource consumption.

A big thank you to our Backers; you rock!

Get Started

Phalcon is written in Zephir/C with platform independence in mind. As a result, Phalcon is available on Microsoft Windows, GNU/Linux, FreeBSD and MacOS. You can either download a binary package for the system of your choice or build it from source.


To install Phalcon on Windows:

  1. Download Phalcon for Windows
  2. Extract the DLL file and copy it to your PHP extensions directory
  3. Edit your php.ini file and add this line:
  4. Finally, restart your web server

Hint: To ensure that your Phalcon installation was successful, debug with

<?php phpinfo(); ?>

and search for a section mentioning the Phalcon extension.


On a Unix-based platform you can easily compile and install the extension from sources.


Prerequisite packages are:

  • PHP 5.5.x/5.6.x/7.0.x/7.1.x development resources (PHP 5.3 and 5.4 are no longer supported)
  • g++ >= 4.4 | clang++ >= 3.x | vc++ >= 11
  • GNU make >= 3.81
  • re2c >= 0.13


# Use actual PHP development headers and tools here
sudo apt-get install php5-dev libpcre3-dev gcc make re2c


# Use actual PHP development headers and tools here
sudo zypper install php5-devel gcc make re2c


# Use actual PHP development headers and tools here
sudo yum install php-devel pcre-devel gcc make re2c

macOS(Sierra / El Capitan / Yosemite):

Using Homebrew

# brew install php<version>-phalcon
# available versions 56, 70, 71

brew install php71-phalcon


Follow these instructions to generate a binary extension for your platform:

git clone git://github.com/phalcon/cphalcon.git
cd cphalcon/build
sudo ./install

If you have specific php versions running

git clone https://github.com/phalcon/cphalcon
cd cphalcon/build
sudo ./install --phpize /usr/bin/phpize5.6 --php-config /usr/bin/php-config5.6

Add the extension to your php.ini:


Finally, restart the web server.


Tests are located in tests/ and use Codeception. Test classes should follow the PSR-2 coding style guide.
