Description:
------------
I use syslog-ng as logging system and call it with php to log my exact message.
The problem is that PHP add the ident string of my openlog to the message.

My syslog-ng destination is configured like this :
destination testing { 
	file(
		"/server/alpha/myapp/testing.log" 
		template("$MESSAGE\n")
	);
};
log {
	source(s_all);
	destination(testing);
};
If I leave the ident string empty, I still have the : added


Reproduce code:
---------------
function syslog($logFacility = false) {
	$r = openlog("testing", LOG_CONS, LOG_USER);
	if(!$r) return false;
	$r = syslog(LOG_NOTICE, "my message to log");
	if(!$r) return false;
	closelog();
}

Expected result:
----------------
The result I expect is : 
my message to log
without any garbage

Actual result:
--------------
The actual result is :
testing: my message to log
