Difference between passing the data type and executing an array without them

I just want to know if these 2 sets of code are doing the same thing or not, if not what's the difference?

$connect= new CONNECT();
$sql = ("query here");
$stmt = $connect->runQuery($sql);
$stmt->bindParam(':sample', $_POST['sample'], PDO::PARAM_STR);
$stmt->bindParam(':sample2', $_POST['sample2'], PDO::PARAM_STR);
$stmt->bindParam(':sample3', $_POST['sample3'], PDO::PARAM_STR);


$connect= new CONNECT();
$sql = ("query here");
$stmt = $connect->runQuery($sql);
':sample1' => $_POST['sample'],
':sample2' => $_POST['sample2'],
':sample3' => $_POST['sample3']

FYI, both work perfectly, just wanting to know if I'm getting the full security benefit using either one. Thanks.

By passing the parameters along with the $stmt->execute() method, all values in the array with be passed, as PDO::PARAM_STR to the statement with the $stmt->bindParam() function.

And with the $stmt->bindParam() function, you can define the data type passed along, using the PDO::PARAM_*
