If you are attempting to access the variable $DB inside the function
scope, like this:
$DB = new DBInterface;
function doSomething() {
$DB->doSomethingElse();
}
Then it will not work unless you either pass $DB to doSomething(), or
declare $DB as a global at the start of the function. Like this:
function doSomething() {
global $DB;
$DB->doSomethingElse();
}
Or access $DB through the globals superglobal. RTFM.
