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
