    Installation

    The FANN PHP extension should work on all Linux
    systems.

    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
      runnning:

      
      $ 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
