PDO Connection Test

Question

I am writing an installer for one of my apps and I would like to be able to test some default database settings.

Is this possible using PDO to test valid and invalid database connections?

I have the following code:

try{             $dbh = new pdo('mysql:host=127.0.0.1:3308;dbname=axpdb','admin','1234');             die(json_encode(array('outcome' => true)));         }catch(PDOException $ex){             die(json_encode(array(                 'outcome' => false,                 'message' => 'Unable to connect'             )));         } 

The problem I am having is that the script trys to connect until the script execution time of 60 seconds runs out instead of saying it cannot connect to the db.

Thanks

you need to set the error mode when connection to the database:

try{     $dbh = new pdo( 'mysql:host=127.0.0.1:3308;dbname=axpdb',                     'admin',                     '1234',                     array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));     die(json_encode(array('outcome' => true))); } catch(PDOException $ex){     die(json_encode(array('outcome' => false, 'message' => 'Unable to connect'))); }
