PHP has a number of magic queries that return images or text that can vary with the PHP version. This script uses the following queries: * /?=PHPE9568F36-D428-11d2-A769-00AA001ACF42: gets a GIF logo, which changes on April Fool's Day. * /?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000: gets an HTML credits page. A list of magic queries is at http://www.0php.com/php_easter_egg.php. The script also checks if any header field value starts with "PHP" and reports that value if found.
