+         Since PHP 5.5.0 these guids and the <function>php_logo_guid</function> function
+         have been removed from PHP and the guids are replaced with data URIs instead.
+         Thus accessing the PHP logo via appending the guid to the URL no longer works.
+         Similarly, turning <parameter>expose_php</parameter> off will not affect
+         seeing the PHP logo in <function>phpinfo</function>.
