Help in Database Procedure returns value

We have a database procedure that returns a value by reference.

This is how it is used in ABF:
h_status = pr_get_passphrase
(h_passphrase = BYREF(:gv_passphrase));

Is it possible to do the same in PHP?

You need to modify the passed value? What is the type? Pass by reference is a means to one or more ends: modification by the callee and avoiding copy overhead, at the cost of additional reference variables and loading and dereferencing reference values. If cost and modification are not concerns, pass by whatever works with the least source code.
