Class 'Logger' not found in LoggerRoot.php

Question

I'm trying to install log4php in a very simple site (trying to learn how it works). Apache is installed in /etc/ and vhost is defined as:

DocumentRoot "/home/fferri/workspace/site-tutorial/www" ServerName tutorial.localhost php_value auto_prepend_file "/home/fferri/workspace/site-tutorial/www/ConfigureSite.php" My site is at /home/fferri/workspace/site-tutorial/www/ and log4php folder is at /home/fferri/workspace/site-tutorial/services/lib/log4php-0.9/src/log4php/

Then, I define

define('LOG4PHP_DIR', "/home/fferri/workspace/site-tutorial/services/lib/log4php-0.9/src/log4php/");

into ConfigureSite.php

And, into another file, I try to init log4php:

include(LOG4PHP_DIR."/Logger.php");
$log = Logger::getLogger("main");
$log->info("foo");
$log->warn("bar");

The error is always the same:

Fatal error: Class 'Logger' not found in /home/fferri/workspace/site-tutorial/services/lib/log4php-0.9/src/log4php/LoggerRoot.php on line 37

It's worth to say that LoggerRoot.php and Logger.php are in the same folder. I think I have a problem of paths because my server and my site aren't in the same folder, but I need some hint

Adding the complete stack trace of error:

So, first, Logger is found but on loading LoggerHierarchy, Logger isn't. Why????

SOLVED: The error is to use log4php-0.9 and php5 together. Downloading the library located in apache web (2.1), the problem is solved.

Thanks!

Answer 2

I think using dirname(__FILE__) will look better.

I also thought it would be the path...

Maybe the Class name defenition then. do you call new Logger in Logger.php?

What about something like:

include(LOG4PHP_DIR."/Logger.php");
$log = new Logger();
$log->info("foo");
