The FANN PHP extension should work on all Linux systems.

- fann.installation.lib
- fann.installation.pecl
- fann.installation.manual

### FANN Library Installation

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

If the library is re-installed manually, then all old library file should be removed before re-installing otherwise the old library version could be linked.

### PECL Installation

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

    $ sudo pecl install fann

### Manual Installation

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 php-fann-master.zip
    $ 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 fann.so. 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/fann.so'

  Make sure that it is the same as the PHP extension directory by running:

      $ php -i | grep extension_dir
        extension_dir => /usr/lib/php/extensions/no-debug-non-zts-20060613 =>
                         /usr/lib/php/extensions/no-debug-non-zts-20060613

  If it's not, change the extension_dir in php.ini or move fann.so.

- To load the extension on PHP startup, add a line:

      extension=fann.so
