/**
* HandlePHPErrors
* This calls the log system to handle the logging of the messages.
* If error_reporting is disabled this does nothing.
* This is the function to call for set_error_handler to use to do all of the logging.
* The GetLogSystem function is one you have to write yourself.
*
* <b>Example</b>
*
* require('path/to/log/interspire_log.php');
* function GetLogSystem()
* {
* static $logsystem = null;
* if (is_null($logsystem)) {
* $logsystem = new Interspire_Log(true, false);
*
* // log which parts of the query string?
* // can be an array or a singular item.
* $logsystem->SetLogActionStrings(array('todo', 'action', 'save'));
*
* // add whatever extra log types are needed.
* // these are on top of the built in types of 'php' and 'sql'.
* $logsystem->SetValidLogTypes(array('notifications', 'blogs', 'shipping'));
*
* // set the types of errors/reports we're actually going to save.
* $logsystem->SetLogTypes(array('sql','php'));
*
* $db = &GetDatabase();
* // need to connect the database to the log system so it can do it's work.
* // it's handled by reference inside the SetDb method.
* $logsystem->SetDb($db);
*
* $logsystem->SetSeverities('all');
* }
* return $logsystem;
* }
*
* // then set the error handler.
* set_error_handler('HandlePHPErrors');
*
*
* @param Int $errno The error number we are logging. This is one of the defined constants like 'E_USER_ERROR'.
* @param String $errstr The error message to log.
* @param String $errfile The filename the error occurred in.
* @param Int $errline The line number the error occurred on.
*
* @return Mixed Returns straight away if error_reporting is disabled. Otherwise it calls the log system to handle the error and then returns true so the error isn't output to the browser.
