Error Handling

PHP developers,

How do you guys usually do error-handling? Do you just output the error, or do you throw it in an array.

I've found it of immense use to throw all error messages into array $error and use php's array functions to perform error handling. Just curious how others take care of this sort of business. Tips? Tricks? Anyone?

Is this too broad of a question?

In simple terms, my scripts die on exception and print a message. No further processing is done. However, I do make a point to send messages that are helpful to end-users.
