Do not tell me which version of php is better to install for zabbix 4.4.7. On the one hand, each subsequent version of php is faster than the previous one by tests. To date, the newest 7.4 from, for example, the remi repository. On the other hand, in Rhel 8.1 OS php 7.2 and 7.3 versions come from the box, and once out of the box means more stable.
