#PHLIPS - CLIPS extension for PHP

##Original repository http://phlips.sourceforge.net

##Motivation The current version of PHLIPS (0.5.1) unfortunately not compiled in new versions of PHP - releases 5.4.x and 5.5.x.
I make little adjusts on source clips.c to working again.

##Install PS.: this tutorial is based on MAMP version 2.2 (acronym for MacOSX + Apache + MySQL + PHP), running on OS X 10.9 Mavericks.

###1. Download

git clone https://github.com/stopassola/phlips.git
cd phlips

###2. Prepare the build environment for a PHP extension /Applications/MAMP/bin/php/php5.5.3/bin/phpize

More information in http://php.net/manual/en/install.pecl.phpize.php

This command print something like:

Configuring for:
PHP Api Version:         20121113
Zend Module Api No:      20121212
Zend Extension Api No:   220121212

####Error: autoconf utility not available

Configuring for:
PHP Api Version:         20121113
Zend Module Api No:      20121212
Zend Extension Api No:   220121212
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

Install the autoconf in your Linux distro and repeat the last command:

sudo apt-get install autoconf

###3. Specify the installation of PHP If you have multiple PHP versions installed, you may be able to specify for which installation you'd like to build by using the --with-php-config option during configuration:

./configure --with-php-config=/Applications/MAMP/bin/php/php5.5.3/bin/php-config

####Error: C compiler is not available

checking for gcc... no
configure: error: in `/home/zend/phlips':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.

Install compiler utilities on your Linux distro and repeat the last command:

sudo apt-get install build-essential

###4. Build module clips.so from source code sudo make

PS.: tested on version 5.5.3 of PHP (running on MAMP 2.2), PHP 5.5.10 (on MAMP 3.0.5) and PHP 5.5.7 (on ZendServer Enterprise 6.3.0 running in Debian GNU/Linux 6.0.9 "squeeze").

###5. Copy the clips.so module to MAMP repository: cp modules/clips.so /Applications/MAMP/bin/php/php5.5.3/lib/php/extensions/no-debug-non-zts-20121212/

###6. Load the CLIPS extension (clips.so) in php.ini (configuration file of PHP) extension=clips.so

###7. Restart the webserver sudo /usr/local/zend/bin/apachectl restart

(command above tested in ZendServer Enterprise 6.3.0 running in Debian GNU/Linux 6.0.9 "squeeze")

###8. Check if extension was install

<?php
phpinfo();
?>

You should view the clips extension:

###9. Test some expert system code:

<?php
clips_clear();
clips_set_strategy(LEX_STRATEGY);
clips_assert("(quesito 2)");
clips_run();
$facts = clips_get_fact_list();
print_r($facts);
?>
