-        Decides whether PHP may expose the fact that it is installed on the server
-        (e.g. by adding its signature to the Web server header). It is no security
-        threat in any way, but it makes it possible to determine whether you use PHP
-        on your server or not.
+        Exposes to the world that PHP is installed on the server, which includes the
+        PHP version within the HTTP header (e.g., X-Powered-By: PHP/5.3.7). The PHP logo
+        guids are also exposed, thus appending them to the URL of a PHP enabled site
+        will display the appropriate logo 
+        (e.g., <link xlink:href="&url.php;?=PHPE9568F34-D428-11d2-A769-00AA001ACF42">&url.php;?=PHPE9568F34-D428-11d2-A769-00AA001ACF42</link>).
+        This also affects the output of <function>phpinfo</function>, as when disabled, the PHP logo
+        and credits information will not be displayed.
