Description:
------------
Note; this might relate to Bug 17648, thus have been around for a while. Hopefully bug will be finally fixed.

-------
Logging messages to system log with plain syslog() (i.e. without using openlog() and define_syslog_variables())creates random garbage/text from memory preceding the actual message.

Example:
A line in any php-file:

syslog(LOG_NOTICE,"insert text here");

/var/log/messages showed:
Jun 10 08:34:30 mail ='crc' VALUE=': insert text here

The preceding text varies, sometimes it is correct (=nothing), sometimes it's longer.

The problem can be solved like this:
define_syslog_variables();
openlog('Info:',LOG_ODELAY,LOG_USER);
syslog(LOG_NOTICE,"insert text here")
->
Jun 10 08:36:12 mail Info: insert text here
----------
Server is Apache 1.3.31 and php compiled as module.

Cannot replicate the bug, moreover you should not be 
calling syslog() without prior openlog() &  
define_syslog_variables() calls.

php.net and openlog();
->
"openlog() is optional. It will automatically be called by syslog() if necessary, in which case ident will default to FALSE."

A Documentation problem then?
