PHP Integrating PHP with Databases Databases and PHP More Exceptions

Why do you need to set PDO::setAttribute()?

I don't understand what's happening when you set the two attributes on the PDO object. She mentions that its so you can see any error that occurs when connecting to a database. But I thought that was the purpose of the try/catch statement?

try {
   //run code if there is no error
} catch(Exception $e) {
 //run this code if there is an error
 $e->getMessage();
}

So, why do you need to include the attributes to flag an error in the try code block?

try {
 // run code if there is no error
 PDO_object->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION)
} catch(Exception $e) {
// run this code if there is an error
 $e->getMessage();
}

Hey Kristian, I think Ms. Alena forced an Exception in the try{} block to demonstrate what happened when there's a successful connection. From what I see it's much cleaner than var_dump().
