php checking array values

Question

Hey all i am trying to figure out a way to see what all values are within the array:

  $sql = "select * from product where type = ? limit 1";
$query = self::$__CONN__->prepare($sql);
$query->execute(array($type)) or die(print_r($query->errorinfo()));

I am new at PHP and im not sure what all that is doing to populate the query string. I am guessing that the first query is connecting to the server and sending out the query but how do i see what its returning back in the array above?

Any help would be great!

Just dump the $type variable

var_dump($type);

Or if you are interested in the array wrapper itself

var_dump(array($type));
