Phalcon is a C extension, so you need to download a binary for your platform or compile it from source code.
The commands below are for v5.0.0. You can adjust them accordingly to install the latest version of Phalcon. For v4, the PSR extension is required to be loaded before Phalcon. Please ensure that it is available in your system.
Using Pecl this extension will be automatically installed in your system The Pecl installation method is available for Windows, Linux and MacOS. Under windows pre-compiled dll files will be used. Under Linux and MacOS it will compile phalcon locally so it could be faster to use a different installation method on these platforms. To install using Pecl make sure you have pecl/pear installed.
pecl channel-update pecl.php.net pecl install phalcon-5.0.0
On Linux you can easily compile and install the extension from source code.
We need some packages already installed:
# Ubuntu sudo apt-get install php8.1-dev php8.1-mysql gcc libpcre3-dev # Fedora sudo dnf install php-devel php-mysqlnd gcc libtool pcre-devel re2c # RHEL sudo yum install php-devel php-mysql gcc libtool pcre-devel # Suse yast2 -i php8-pear php8-devel php8-mysql gcc libtool pcre-devel # macOS (Homebrew) brew install pcre brew tap phalcon/extension https://github.com/phalcon/homebrew-tap brew install phalcon # macOS (MacPorts) sudo port install php81-phalcon
1. To create the extension from C source follow these steps:
git clone --depth=1 "git://github.com/phalcon/cphalcon.git" cd cphalcon/build sudo ./install
2. Add the extension to your php.ini:
3. Finally, restart the webserver
There is a PKGBUILD for ArchLinux, available here
A port is available for FreeBSD. You only need these few commands to install it:
pkg_add -r phalcon
cd /usr/ports/www/phalcon && make install clean
After requests from the community, the cPanel developers released a custom module that allows for installation of Phalcon in cPanel hosted sites. Information can be found here. The module is maintained in Github.
Although Phalcon does not binary link to other extensions it does use some of them to offer functionality. The extensions used are:
It is not necessary for all the above extensions to be present in the system that has Phalcon installed. You can only install the ones that meet your needs. For instance if you use a MySQL database, then you can only load PDO and PDO/MySQL ignoring the Oracle, SQlite, Postgresql and Mongo.
