 This product includes PHP software, freely available from <http://www.php.net/software/> 

Version 3 of PHP used a dual license - PHP 3's source is available under either the PHP License or the GNU General Public License (GPL). This practice was discontinued as of PHP 4, with PHP's developers citing the restrictions on reuse associated with the GPL's copyleft enforcement as being the reason for dropping it.^[3]
