For this, the $cfg['LeftDisplayServers'] parameter must be set to TRUE . The
list of servers can have two forms—a drop-down list or links. Which form appears
depends on $cfg['DisplayServersList'] . By default, this parameter is set to
FALSE , so we see a drop-down list of servers. Setting $cfg['DisplayServersList']
to TRUE produces a list of links to all defined servers.
Handling many databases or tables
This section describes some techniques to cope with a server holding a huge number
of databases and tables.
Limits on the interface
It would be difficult to work with the interface if we had access to hundreds or even
thousands of databases, or hundreds of tables in the same database. Two parameters,
shown here with their default values, establish a limit on the number of databases
and tables displayed, by adding a page selector and navigation links:
$cfg['MaxDbList'] = 100;
$cfg['MaxTableList'] = 250;
The effect of setting $cfg['MaxTableList'] to a value of 5 can be seen on the
navigation panel, shown here for a database having more than five tables:
The page selector and navigation links also appear in the main panel.
