PEAR.php / Log.php

I hava a dilema on how to most efficiently use the PEAR Error logging mechansim. What I need is a package-wide system of throwing errors (db, query, user...) and logging them into a file. Currently I am using these classes from PEAR. include_once('PEAR.php'); include_once('Log.php'); include_once('Log/file.php'); Every class in my package extends PEAR (not directly, but via a base package class that 'extends PEAR') and initializes the error logging mechanism in its constructor like this: $this->PEAR(); $callback = array($this,'_logError'); // _logError is my error logging method $this->setErrorHandling(PEAR_ERROR_CALLBACK, $callback); Each method returns a PEAR_Error on failure as such return $this->raiseError($errstr, 0, null, null, $dbgstr); and the baseclass::_logError is called which then logs the error Is this the "proper way" of doing things. It seems a little bit of an overhead to extend PEAR to my every class and even to initialize. Maybe I needn't call $this->PEAR()? Do I? I would like to keep the raiseError() functionality so that the logging mechanism get called automatically. Input is welcome. Cheers Roko Roic
