The write() method can use a similar construct: function write() { if ( ! is_writeable( $this->file ) ) { throw new Exception("file '{$this->file}' is not writeable"); } file_put_contents( $this->file, $this->xml->asXML() ); } Our __construct() and write() methods can now check diligently for file errors as they do their work, but let code more fitted for the purpose decide how to respond to any errors detected. So how does client code know how to handle an exception when thrown When you invoke a method that may throw an exception, you can wrap your call in a try clause. A try clause is made up of the try keyword followed by braces. The try clause must be followed by at least one catch clause in which you can handle any error, like this: try { $conf = new Conf( dirname(__FILE__)."/conf01.xml" ); print "user: ".$conf->get('user')."\n"; print "host: ".$conf->get('host')."\n"; $conf->set("pass", "newpass"); $conf->write(); } catch ( Exception $e ) { die( $e->__toString() ); } As you can see, the catch clause superficially resembles a method declaration. When an exception is thrown, the catch clause in the invoking scope is called. The Exception object is automatically passed in as the argument variable. Just as execution is halted within the throwing method when an exception is thrown, so it is within the try clause control passes directly to the catch clause.

You can create a variety of tracking lists by clicking Create from the Site Actions menu. These lists help you to keep track of pieces of information such as links to other pages or sites, calendar events, tasks, issues, or even surveys. In fact, when you look under the Tracking group, you will find these six list types: Links Calendar Tasks Project Tasks Issue Tracking Survey Agenda

Note also that while it is perfectly safe to ignore the IAsyncResult result from Control. BeginInvoke, it s not perfectly free: IAsyncResult has a WaitHandle member ( 17), and WaitHandle has a finalizer. If you don t EndInvoke, the WaitHandle will eventually be finalized.

As per 2, this is a comparatively expensive operation, though it does seem safe to assume that a WaitHandle will never point to lots of other objects that will need to be resurrected. If you use Control.BeginInvoke to fire-and-forget a lot of operations from non-GUI threads, you can minimize this finalization cost (and reduce OS resource usage) by calling WaitHandle.Close on the IAsyncResult that you get from Control.BeginInvoke but be sure that the IAsyncResult.IsCompleted property is set (true) before you call Close. Closing the WaitHandle before the asynchronous operation signals completion will cause an exception when the invoked delegate returns. One way to minimize resource usage without blocking is to append each fire-and-forget IAsyncResult to a synchronized list. A low-priority background thread could scan this list every few seconds, and Close the WaitHandle of any IAsyncResult that IsCompleted.

You can create classes that extend the Exception class as you would with any user-defined class. There are two reasons why you might want to do this. First, you can extend the class s functionality. Second, the fact that a derived class defines a new class type can aid error handling in itself. You can, in fact, define as many catch clauses as you need for a try statement. The particular catch clause invoked will depend upon the type of the thrown exception and the class type hint in the argument list. Let s define some simple classes that extend Exception: class XmlException extends Exception { private $error; function __construct( LibXmlError $error ) { $shortfile = basename( $error->file ); $msg = "[{$shortfile}, line {$error->line}, col {$error->col}] {$error->message}";

You might think of the links list as the simplest of the lists in the Tracking group, as it consists of a collection of links to other pages. Once you have more than about a dozen links, you might
