php - Get the last auto increment id

Question

lets say my code is:

$req = $bdd->prepare('INSERT INTO test(name, surname) VALUES(:name, :surname)');
$req->execute(array(
    'name' => $name,
    'surname' => $surname));

And my table test has an auto increment field named id

What is the best way to get the 'id' corresponding to $req?

Answer 1

PDO 有一个方法：

$id = $pdo->lastInsertId();

或者在你的情况下：

$id = $bdd->lastInsertId();
