Sameer Borate has posted some of his thoughts about logging in PHP applications and how it can be one of the most important things you do.

This usually depends on what kind of application you are developing.

He gives an example of logging on database intensive applications - storing the query execution state - complete with a simple example of an "addUser" method that logs any issues caused by the query execution.
