Ralph Schindler's Blog: Exception Best Practices in PHP 5.3
Ralph Schindler has put together a new post for his blog about some of the best practices for using exceptions in PHP 5.3 - specifically dealing with some of the new functionality that comes with this latest PHP version.
Exception handling in PHP is not a new feature by any stretch. In this article, we'll discuss two new features in PHP 5.3 based around exceptions. The first is nested exceptions and the second is a new set of exception types offered by the SPL extension (which is now a core extension of the PHP runtime). Both of these new features have found their way into the book of best best practices and deserve to be examined in detail.
Some of the features he talks about were pre-PHP 5.3, but the focus is largely on these new features. He gives a bit of a background on exception handling in PHP and how custom exceptions could be thrown. He then moves on to the new features - first nesting exceptions and then some about the new core exception types (found here). All that being said, he includes some code to show the dynamic/logic/runtime exceptions in action including a look at best practices in library exception handling.
