Subject: References in the session
From: come@opensides.be (=?ISO-8859-1?Q?C=F4me?= Chilliet)

Hello,

In the $_SESSION documentation we can see the following warning: "You c=
an't use references in session variables as there is no feasible way to=
 restore a reference to another variable."
In our application, references where stored in the session and it *seem=
ed to* work fine under PHP5, and it broke with PHP7.

I removed as much references uses as possible, but it=E2=80=99s sometim=
es hard to guess which objects will end up in the session or not in a c=
omplex application.

So, what would help me would be if PHP emit a warning when my code trie=
s to store a reference in the session.
Because right now, it silently fails and I get random errors later when=
 using objects restored from the session.

Is it possible to get such a warning?
If not, is it something that could/should be added?

Silent failing is always a bad option in my opinion.
