Is bitrix (v20.0.1198) and php7.4 compatible?

Question

1C-Bitrix

Does anyone have any positive experience with migrating to php 7.4 or is it still too early.
On the official site, the recommended version of php is 7.2.

Answer 1

TLDR: It's still early.

Update: I'm sorry.
Messed up with the version: from 08/01/2020 it will require php 7.2, but php7.4 is recommended will work (for the most part). It will start, but will not work correctly at 100%.
It has been officially announced that from July 1 (or June) 2020, the platform will require php 7.2. I assume that a few days before the release there will be an update that will replace the str*-functions with mb_* functions and you will be able to use the latest version of the platform on php 7.4.
If you use bitrix env, then the php version upgrade will be released a little later (as always late).

Answer 2

Updated today.
I swear at "UTF settings (mbstring and BX_UTF constant)
Error! The strlen string function does not work correctly.", the site seems to work without errors ...

Answer 3

There are no recommendations even for 7.3. What's the point of switching to 7.4?
The demo store runs on 7.4 and runs without errors.

Answer 4

7.2 and 7.3 work - Reg.ru hosting
on 7.4 on all editions Error working with sockets with all the consequences when checking the system
on 7.3 when checking the system everything is correct
when installing there are no errors
, they wrote that mbstring.func_overload other than 0 is outdated, but when registered in ini file value 2
check passes

Answer 5

Bitrix 24 does not work with 7.4.8 gives an error in the admin panel - some kind of problem with DateTime serialization.
