Screen littered with PHP deprecation notices

[jancs]

Hi!
having fresh install of Zabbix 5.0.42 after login in Zabbix frontend I get screen littered with such messages:

etc.
PHP 8.3.9. How to get rid of them staying with Zabbix version 5? Downgrade of PHP, while not very welcome, is an option, if helps.

2 Requirements (zabbix.com)



So, either downgrade PHP to 7.2 or upgrade Zabbix to 6.0, 6.4 or 7.0. Preference here would be to upgrade Zabbix to 7.0, given 5.0 is EOL. If you need an interim step, go to 6.0 LTS. It's under active support for another 7 months with security patches for 2yrs 7mos.

Edit: Also -> 8 Upgrade procedure (zabbix.com)

Zabbix 6.0.26 or higher support PHP 8.3.
Zabbix 6.4.11 supports PHP 8.3

I gave up trying to live with the compact version of Zabbix (v5) as php 7 can not be compiled on Slackware64-current any longer, so I installed 7.0.1. Hope, for my active lifetime it will be enough staying with 7 LTS
