syslog

(PHP3 <= 3.0.16, PHP4 )

syslog -- Generate a system log message

Description

int syslog (int priority, string message)

Syslog() generates a log message that will be distributed by the system logger. priority is a combination of the facility and the level, values for which are given in the next section. The remaining argument is the message to send, except that the two characters %m will be replaced by the error message string (strerror) corresponding to the present value of errno.

More information on the syslog facilities can be found in the man pages for syslog on Unix machines.

On Windows NT, the syslog service is emulated using the Event Log.

In Windows NT, use the following values of priority: 1 = error, 6 = info

The text was taken directly out of a unix man page. On a unix system do man 3 syslog and you wil get the info

[I hope the HTML comes out right...] For the-header-file-enabled: man 3 syslog defines the priorities, but not the integer values. For that you'll need to read your system header file.

Let's suppose I want to log an informational message in the mail log (which happens to be true). The man page tells me I want LOG_MAIL|LOG_INFO. So I look in /usr/include/sys/syslog.h and find (this happens to be Linux, your system could be different): <pre> #define LOG_INFO 6 /* informational */ #define LOG_MAIL (2<<3) /* mail system */ </pre> 2<<3 means shift 3 bits left, which means multiply by 8. So I want 2*8 + 6 = 22. syslog(22,"this message will appear in the mail log"); And indeed it does.

Using PHP3, the documentation does not match the actual implementation. To generate a syslog, I found the following code will work:

<PRE> syslog("local7.info", "syslog message") </PRE> when the manual says the first argument should be an integer.
