Installation

PHP extensions require a slightly different installation method to a traditional PHP-based library or framework. You can either download a binary package for the system of your choice or build it from the sources.

Windows

To use phalcon on Windows you can download a DLL library. Edit your php.ini file and then append at the end:

extension=php_phalcon.dll

Restart your webserver.

The following screencast is a step-by-step guide to install Phalcon on Windows:

Linux/Solaris

Debian / Ubuntu

To add the repository to your distribution:

# Stable releases
curl -s https://packagecloud.io/install/repositories/phalcon/stable/script.deb.sh | sudo bash

# Nightly releases
curl -s https://packagecloud.io/install/repositories/phalcon/nightly/script.deb.sh | sudo bash

This only needs to be done only once, unless your distribution changes or you want to switch from stable to nightly builds.

To install Phalcon:

sudo apt-get install php5-phalcon

# or for PHP 7

sudo apt-get install php7.0-phalcon

RPM distributions (i.e. CentOS)

To add the repository to our distribution:

# Stable releases
curl -s https://packagecloud.io/install/repositories/phalcon/stable/script.rpm.sh | sudo bash

# Nightly releases
curl -s https://packagecloud.io/install/repositories/phalcon/nightly/script.rpm.sh | sudo bash

This only needs to be done only once, unless your distribution changes or you want to switch from stable to nightly builds.

To install Phalcon:

sudo yum install php56u-phalcon

# or for PHP 7

sudo yum install php70u-phalcon

Compile from source

On a Linux/Solaris system you can easily compile and install the extension from the source code:

Prerequisite packages are:

• PHP >= 5.5 development resources
• GCC compiler (Linux/Solaris)
• Git (if not already installed in your system - unless you download the package from GitHub and upload it on your server via FTP/SFTP)

Specific packages for common platforms:

# Ubuntu
sudo apt-get install php5-dev libpcre3-dev gcc make php5-mysql

# Suse
sudo yast -i gcc make autoconf php5-devel php5-pear php5-mysql

# CentOS/RedHat/Fedora
sudo yum install php-devel pcre-devel gcc make

# Solaris
pkg install gcc-45 php-56 apache-php56

Creating the extension:

git clone git://github.com/phalcon/cphalcon.git

cd cphalcon/build

sudo ./install

Add extension to your PHP configuration:

# Suse: Add a file called phalcon.ini in /etc/php5/conf.d/ with this content:
extension=phalcon.so

# CentOS/RedHat/Fedora: Add a file called phalcon.ini in /etc/php.d/ with this content:
extension=phalcon.so

# Ubuntu/Debian with apache2: Add a file called 30-phalcon.ini in /etc/php5/apache2/conf.d/ with this content:
extension=phalcon.so

# Ubuntu/Debian with php5-fpm: Add a file called 30-phalcon.ini in /etc/php5/fpm/conf.d/ with this content:
extension=phalcon.so

# Ubuntu/Debian with php5-cli: Add a file called 30-phalcon.ini in /etc/php5/cli/conf.d/ with this content:
extension=phalcon.so

Restart the webserver.

If you are running Ubuntu/Debian with php5-fpm, restart it:

sudo service php5-fpm restart

Phalcon automatically detects your architecture, however, you can force the compilation for a specific architecture:

cd cphalcon/build

# One of the following:
sudo ./install 32bits
sudo ./install 64bits
sudo ./install safe

If the automatic installer fails try building the extension manually:

cd cphalcon/build/64bits

export CFLAGS="-O2 --fvisibility=hidden"

./configure --enable-phalcon

make && sudo make install

Mac OS X

On a Mac OS X system you can compile and install the extension from the source code:

Requirements

Prerequisite packages are:

• PHP >= 5.5 development resources
• XCode

# brew
brew tap homebrew/homebrew-php
brew install php55-phalcon
brew install php56-phalcon

# MacPorts
sudo port install php55-phalcon
sudo port install php56-phalcon

Add extension to your PHP configuration.

FreeBSD

A port is available for FreeBSD. Just only need these simple line commands to install it:

pkg_add -r phalcon

or

export CFLAGS="-O2 --fvisibility=hidden"

cd /usr/ports/www/phalcon

make install clean

Checking your installation

Check your phpinfo() output for a section referencing “Phalcon” or execute the code snippet below:

<?php print_r(get_loaded_extensions()); ?>

The Phalcon extension should appear as part of the output:

Array
(
    [0] => Core
    [1] => libxml
    [2] => filter
    [3] => SPL
    [4] => standard
    [5] => phalcon
    [6] => pdo_mysql
)
