HOWEVER: it is not a good idea, imho, to "always" let the errors bubble up to the outer layer, which is what Paul seemed to have typed... The problem with that approach is that you end up being painted into a corner where your application can do little more than print "It broke." because the low-level context is not available to the caller of the function. The lowest layers of your application should be logging very precise info about the error for the developer, with code for every possible error condition you can think of, and hopefully defaults for error conditions you can't think of. The middle layers might return a smaller set of common error codes/messages. The outer layer might lookup error codes to print suitable end-user messages, or translate with gettext or... In an ideal world, the outer layer presents the end user with something meaningful to them, while providing an error code or unique identifier that a developer can use to locate the detailed info needed to fix the problem. -- Some people have a "gift" link here.
