Valid DB Handle Assertion Test

[JCervoni]

Can I test for the existence of a method without actually calling it?

Basically what I'm trying to do is to verify that $dbh is still a valid
handle.
I want to use this as an assertion test at the start of a function.

# verify that the $dbh is valid
if ( !defined($dbh->disconnect() ) )
     {
     print "dbh is invalid\n" ;
     exit 1
     }

# $dbh is valid so we can safely disconnect
$dbh->disconnect()
