> The easiest way to install FANN-PHP is to use PEAR- if you
have a fairly recent version of PHP installed, simply run
<B
CLASS="command"
>pear install fann</B
>. Note that if there are
no stable releases of FANN-PHP, you may have to specify the
URI for the package, which can be obtained from <A
HREF="http://pecl.php.net/fann"
TARGET="_top"
>http://pecl.php.net/fann</A
>.
</P
><P
> If you cannot install FANN-PHP using PEAR, you can try
following the (obsolete) instructions at <A
HREF="http://www.cs.utexas.edu/users/UTCS/online-docs/php/pear/faq.install-pecl.html"
TARGET="_top"
>http://www.cs.utexas.edu/users/UTCS/online-docs/php/pear/faq.install-pecl.html</A
>.
</P
><P
> If you use one of these methods, you'll need to either
dl('fann.so') or add it to your php.ini
</P
><P
> If you use either of the above methods, you will probably need
to be root.

</P
><P
> If you wish to compile FANN-PHP into PHP itself, you
can. First, uncompress the package into the ext subdirectory
of your copy of the PHP source code, and rename the
directory to ext/fann (from fann-x.x.x).
</P
><P
> Next, you must rebuild the configure script- to do so, run
<B
CLASS="command"
>./buildconf</B
> from the PHP source
directory.
</P
><P
> From here on, the procedure is similar to when you built PHP
originally- run <B
CLASS="command"
>./configure</B
> with your
desired options, plus <VAR
CLASS="parameter"
>--with-fann</VAR
>.
</P
><P
> Finally, run <B
CLASS="command"
>make</B
> and <B
CLASS="command"
>make
install</B
>. Note that you will probably need to be
root for <B
CLASS="command"
>make install</B
> to work.
</P
><P
> This method may require flex and bison to work- more
information can be obtained at <A
