Thanks for the pointer. Yes, I was writing to stdout. I didn't know
about PHP's syslog call
(<a class="moz-txt-link-freetext" href="http://php.net/manual/en/function.syslog.php">http://php.net/manual/en/function.syslog.php</a>) which produces output
that goes to systemd log and can be manipulated with journalctl.
That should solve my problem.<br>

How? Writing to stdout?

using journalctl. I would like to be able to filter on the message priority

I think you should use syslog, and/or systemd-/journald-specific means, e.g.:
<a class="moz-txt-link-freetext" href="https://github.com/systemd/php-systemd">https://github.com/systemd/php-systemd</a>
Best,
