confusion

[prezident]

$sql = "INSERT INTO entries(title, entry) VALUES (?, ?)";
$stmt = $db->prepare($sql);
$stmt-> execute(array($title, $entry));
$stmt->closeCursor();

I'm confused but i think i gotta just stop the self doubt -> i'm confused about what these code does ok

i know the insert statement

$stmt = $db->prepare($sql) = i'm guessing this prepares the $sql variable and prepares it for execution and stores the (?, ?) as an array with ($title, $entry) keys. am i right ?
