~$ grep log-driver /etc/docker/daemon.json 
    "log-driver": "syslog",
~$ docker run php php -r 'syslog(LOG_ERR, "ABC123");'
~$ cut -d ' ' -f6 /var/log/syslog | grep ABC123 || echo NOT FOUND
NOT FOUND

Why?
And in any case outside docker works

~$ php -r 'syslog(LOG_ERR, "ABC123");'
~$ cut -d ' ' -f6 /var/log/syslog | grep ABC123 || echo NOT FOUND
ABC123

For the same reason why the logger command didn’t work

There is no syslog in the container. Since I obiously failed to explain it in the other topic, I hope someone else will find a better way to do it.

Ok, in other words, the syslog() php function does not take advantage of the docker logging driver
