Logging the user's IP with log4php

[Lst Recv <li...@gmail.com>]

Is there anyway to have it include the user's IP address,
PHPSESSIONID, URL, and filename/linenumber?  These things are very
useful - more than a PID etc in PHP.

You can use the method LoggerLoggingEvent::getMDC() (see LoggerMDC class for details).
If you use the LoggerPatternLayout a conversion character %X{clientNumber} is what you need.
With %X{server.REMOTE_ADDR} you get the client IP address.
Put any key/value pair using the static method LoggerMDC::put(key, value) and get the value via %X{key}.

Example:
----
LoggerMDC::put('sessionid', session_id());
....
in log4php.xml
...
    <appender name="default" class="LoggerAppenderEcho">
        <layout class="LoggerPatternLayout">
            <param name="conversionPattern" value="%-5p [%t] [%X{sessionid}]: %m in %F line %L%n" />
        </layout>
    </appender>
....

For filename/linenumber:
with LoggerPatternLayout use the %F, %L conversion chars and with LoggerLayoutHtml, LoggerXmlLayout set the "locationInfo" property
"true". (with locationInfo enabled every log event calls a debug backtrace... (see LoggerLoggingEvent::getLocationInformation()).
