Everyone talks about how important exception handling is. I have never had the need to handle them until recently:
try {
$pdo = new PDO($dns);
} catch (Exception $e) {
throw new Exception($e);
}
Another more general example would be:
if ($something) {
throw new Exception('Ouch! I can't do that!');
}
After a little online research, I found that many examples/solutions online simply echo them. (PDO Exception Questions - How to Catch Them) Some don't have solutions. (Catching PDOException in lower layer and re-throwing as different exception to upper layer) & (Where to catch exception in PHP MVC application?) And others, I just dont understand. (Where to catch exceptions)
Question #1: Where should I catch exceptions; in the Model or Controller of a MVCish framework?
Question #2: What should catching it do? Log it, email it, display 503?
