3.1. Prerequisites

In the INSTALL file of PHP-Nuke, we read the following about its requirements:

In order to setup PHP-Nuke the folowing prerequisits are necessary.

• Linux, installed and working properly.

• Apache Web Server.

• PHP version 4.1.x or better (mod_php) Apache module.

• MySQL database server

...The above doesn't mean it will not work with other configurations, OS's, DB's, etc, but we only provide INSTALL instructions for the above configuration. In fact PHP-Nuke works under Windows (all), FreeBSD, OS/2, MacOS, etc.

	PHP 4.1.0 or later needed!
	From the INSTALL file, we see that you must have at least PHP 4.1.0 to use PHP-Nuke 6.5 and later. This is an important piece of information that you should ckeck before proceeding. See Warning: Invalid argument supplied for foreach().

You see, it is always a good idea to read the INSTALL file that comes with a software package.

To see the PHP version you are running and do also a small test on your configuration, you can run the test.php file as described in Section 3.9.1.1.

	PHP-Nuke and databases other than MySQL
	From PHP-Nuke version 5.3, Francisco added a new SQL abstraction layer. It enables PHP-Nuke to support databases other than MySQL, like mSQL, PostgreSQL, PostgreSQL_local, ODBC, ODBC_Adabas, Sybase and Interbase.

For the Microsoft Internet Informaion Server (IIS), some tests we have done were positive, some others indicated that a special configuration was needed.
