Description:
------------
I catch wrong rsyslog parameters in fpm-php logs

here is wrong rsyslog parameters :

syslogtag=ool
programname=ool
app-name=ool
procid=

Test script:
---------------
Debian9 stretch
PHP 7.0.27-0+deb9u1 (cli) (built: Jan  5 2018 13:51:52) ( NTS )
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
rsyslogd 8.24.0,

"php-fpm.conf":
error_log = syslog
syslog.facility = daemon
syslog.ident = php7.0-fpm
log_level = notice

"test.php":
<?php
trigger_error("E_USER_WARNING", E_USER_WARNING);

rsyslog template:
template(name="ALL" type="string" string="%timegenerated% -HOSTNAME=%HOSTNAME% -syslogtag=%syslogtag% -programname=%programname% -syslogfacility=%syslogfacility% -syslogfacility-text=%syslogfacility-text% -syslogseverity=%syslogseverity% -syslogseverity-text=%syslogseverity-text% -syslogpriority=%syslogpriority% -syslogpriority-text=%syslogpriority-text% -inputname=%inputname% -app-name=%app-name% -procid=%procid% -msgid=%msgid% -fromhost=%fromhost% -fromhost-ip=%fromhost-ip% %msg%\n")



Expected result:
----------------
it should be better to have 'www-test[6681]' prepending message for the syslogtag parameters :

syslogtag=www-test[6681]
programname=www-test
app-name=www-test
procid=6681

At least 'pool' or 'Pool' in place of 'ool' to filter messages in syslog.

Actual result:
--------------
php-fpm log:
