Steps to reproduce:

1. Setup zabbix 5.4.7 (server + agent2)
2. Apply PHP-FPM by Zabbix agent to host and follow configuration steps.
3. Excecute the item php-fpm_ping
4. The dependent item php-fpm.ping returns 0 even if the reply is correct (pong).

The preprocessing step of the item php-fpm.ping that tries to match the regexp {$PHP_FPM.PING.REPLY}($|\n)}. The problem is the "($|\n)", if I remove that part the regexp works correctly. 

Result:

Here is a sample output of the php-fpm_ping item:

HTTP/1.1 200 OK

Expected:

The regexp to match if the response is pong.
