The FANN PHP extension should work on all Linux systems.

Before you start installation make sure that libfann is installed on your system. It's part of the main repository in the most Linux distributions (search for `fann`). You need a development version.

If it is not installed, you need to install it first. Either download it from the » official site or get it from your distro repository. For example on Fedora:

$ sudo yum install fann-devel

or Ubuntu:

$ sudo apt-get install libfann-dev

This extension is available on PECL. The installation is very simple. Just run:

$ sudo pecl install fann

For developers and people interested in the latest changes, you can compile the driver from the latest source code on » Github. Go to Github and click the "Download ZIP" button. Then run:

$ unzip
$ cd php-fann-master
$ phpize
$ ./configure
$ make all
$ sudo make install

Make the following changes to php.ini:

  • Make sure the extension_dir variable is pointing to the directory containing The build will display where it is installing the PHP driver with output that looks something like:

    Installing '/usr/lib/php/extensions/no-debug-non-zts-20060613/'
    Make sure that it is the same as the PHP extension directory by runnning:
    $ php -i | grep extension_dir
      extension_dir => /usr/lib/php/extensions/no-debug-non-zts-20060613 =>
