Exceptions and warnings can be tossed out from your code at some odd locations sometimes. There's a few options that you have when they jump out, including pushing them out to an error log or just ignoring them completely. Alexander Netkachev has a different solutions, though - handling them with something already built into PHP, using exception reporting.
This coding tip demonstrates how to deal with PHP core notices and warning (aka recoverable errors) in the exception way, using try/catch statement.
IT's a simple idea, but it can definitely help you keep all of you errors in one place. The sample code he gives shows both a basic idea of the solution and a bit more complex example, providing more detailed messages for different exception types.
