Create the function split_location to return the associative array or, if it is invalid, throws an exception. If PHP4, replace the exception with similar error handling.
If efficiency is really the goal, then the OP probably shouldn't go the route of Exceptions. Just use a simple trigger_error() and your php.ini to direct where the error messages go. Especially in this case... because errors here are likely just because someone added / removed an extra "|" where it didn't belong.
In my opinion you should save exceptions for, well, EXCEPTIONal problems. Either that or you use exceptions for a large system that discriminates against specific types of errors and handles each error type in a totally different way. Can we say bloat?
