Luckily you can still maintain backward compatibility by sub-classing ADOdb and using the $ADODB_NEWCONNECTION variable. $ADODB_NEWCONNECTION allows you to override the behaviour of ADONewConnection(). ADOConnection() checks for this variable and will call the function-name stored in this variable if it is defined.
