How to treat exception in best way in construct?

option1 - catch exception where object created:

class Account {
    function __cons         


        

Answer 1

Of course, you should handle an exception thrown in a function outside this function, otherwise it won't make any sense. In regard to constructors specifically, try to avoid "new classname" as much as possible and stick to generator functions instead. For each class X, decide which class is responsible for creating objects of class X, and add a generator function to that class. This generator function is also the perfect place to handle X's constructor exceptions

 class AccountManager {
     function newAccount($id) {
        try {
           $obj = new Account($id);
        } catch....
           return null;
      }
 }

 // all other code uses this instead of "new Account"

 $account = $accountManager->newAccount($id);
