com_get
Note that if you want to use a string to specify the method to call (e.g. a drop-down list to decide what to do to a server process) you can do this in three ways.
The first is to use this function, as in <?php com_invoke($obj, $_GET['func']); ?>
That's bad.
The second is to use eval(), as in <?php eval("\$obj->{$_GET['func']}();"); ?>
That's very very very *very* bad.
The third is to use call_user_func(), as in <?php call_user_func(array($obj, $_GET['func'])); ?>
That's very good.
Remember to validate the user input against a list of allowed methods if a non-admin is at the console.
