OCI8 drivers notice on getServerVersion, "matches" is always undefined

[SylvainSimonGPA]

Bug Report

Q	A
BC Break	yes
Version	3.1.3 (I upgraded from 2.13.5)

Summary

The driver fail on "Connection" class for Oracle database. I have a notice everywhere like this.

For sure, the matches array is always undefined when the instruction is in assert. I don't know why.
If you move the preg_match instruction outside, its work like a charm.

Current behaviour

All is in the previous capture.

How to reproduce

Juste using this kind of connection, and listen notice error. In symfony is the default.

And that's the solution. Depending on your php.ini settings, instructions inside an assert() might not be executed.

Do you want to provide a PR?

Oh... i don't know what is this configuration, i'v a basic php setup on windows. I'v look the zend.assertions in my configuration, its -1 in production, i imagine its this that your talking.

So this is a real problem in doctrine/dbal ? I have never done PR on open-source projects yet haha I don't know if I would be able to :D

Exactly. If you set this to 0 or 1, your problem should be gone. But -1 is the recommended production setting.

No worries. Can you have a look at #4995? Is that what you did to fix the issue?
