Assigning the return value of new by reference is deprecated

by

In PHP5 this idiom is deprecated

$obj_md =& new MDB2();

You sure you’ve not missed an ampersand in your sample code? That would generate the warning you state, but it is not required and can be removed.

To see why this idiom was used in PHP4, see this manual page (note that PHP4 is long dead and this link is to an archived version of the relevant page)
