$cfg['Servers'][$i]['verbose']
Type: string
Default value: ''Only useful when using phpMyAdmin with multiple server entries. If set, this string will be displayed instead of the hostname in the pull-down menu on the main page. This can be useful if you want to show only certain databases on your system, for example. For HTTP auth, all non-US-ASCII characters will be stripped.
