php custom exceptions

Question

I was wondering how would one go about writing custom exception handlers.

so that I can do something like

throw new dbException($sql, $message);

and have it output

There was an error in your query Message: {$message here}
Query: {$sql here}
Line: {line exception was thrown on}
File: {file exception was thrown from}

but I also want to to catch eg syntax errors and parse errors (if possible)
