Question

When i am using try catch block for example:

try{
     require_once('../php/connect.php');
     $dbh = db::getInstance();
     // What i am trying to understand should i close the connection here before the header?
     header("Location: x.php");
   }
} catch(PDOException $e){
   require_once('err.php');
 }
 $dbh = null; // Or should i close the connection here?

Is the “interpreter” even get after line “5”, Thank you all and have a nice day.

Answer 1

Since you are not using exit after header() (which is recommended), your code will continue to execute.

As such, it does not matter if you put in on line 4 or 10. Furthermore, as pointed out by prodigitalson, you do no need to explicitly close the database connection.
