could you please specify zabbix version as well ?
also note that php7 is not even released yet

zalex_ua Issue summary contains "zabbix-2.4.5".
I've just added it to Affect version.

> also note that php7 is not even released yet

I opened the bug with that in mind. Just for the record so to speak.

cheers
t.

with the final php7 out yesterday (december 3rd), this issue might be worth re-evaluating

Confirm the issue with PHP 7.0.2 and Zabbix 2.4.7:

Hopefully someone commits something prettier.

@Stefan de Konink, this does not fix logout.

It does. I have just deployed it.

Umm, sorry, missed changed return statement. Works for me as well, thanks!

gunarspujats CLOSED

Successfully tested!

Fixed in:

• pre-3.0.2rc1 r58902
• pre-3.1.0 (trunk) r58903

(2) API changelog updated

gunarspujats CLOSED

the changelog entry says "fixed API receiving null and false instead of an array in method parameters"

this issue was about zabbix frontend + php7.

is zabbix frontend now officially working & supported with php7 ? if so, should that be mentioned in the changelog, maybe ?

iivs It's not about all php7 related problems in the frontend. If such problems occur, it should be split into multiple tasks. There could be numerous things for improvements and so on. The issue was about user trying to log out on php7 and got a fatal error. The main problem occurred deeply in API core. There were more ways to generate fatal errors breaking the API, just by simply not giving "params" in request. In other words - function arguments. The thing that was fixed, was that API received "null" and "false" instead of an array. I cannot say for sure that it fully supports php7, I haven't run the tests. Bugs could be hidden deeply in the code. We just haven't found them yet. Claiming to fully support php7 and getting a new issue the next day would be silly. Most of the frontend should work on php7, but I'm very suspicious.

iivs I ran some tests. So far sniffers couldn't find anything useful. But unit tests don't work.
