Log_observer()

Log_observer::Log_observer

(

$priority = PEAR_LOG_INFO

)

Creates a new basic Log_observer instance.

Parameters

integer

$priority

The highest priority at which to receive log event notifications.

@access public

Definition at line 50 of file observer.php.

    {
        $this->_id = md5(microtime());
        $this->_priority = $priority;
    }

notify()

Log_observer::notify

(

$event

)

This is a stub method to make sure that Log_Observer classes do something when they are notified of a message.

The default behavior is to just print the message, which is obviously not desireable in practically any situation - which is why you need to override this method. :)

Parameters

array

$event

A hash describing the log event.

Definition at line 125 of file observer.php.

    {
        print_r($event);
    }
