Pdo last id

Beware of lastInsertId() when working with transactions in mysql. The following code returns 0 instead of the insert id.



<?php

try {

    $dbh = new PDO('mysql:host=localhost;dbname=test', 'username', 'password');



    $stmt = $dbh->prepare("INSERT INTO test (name, email) VALUES(?,?)");



    try {

        $dbh->beginTransaction();

        $tmt->execute( array('user', 'user@example.com'));

        $dbh->commit();

        print $dbh->lastInsertId();

    } catch(PDOExecption $e) {

        $dbh->rollback();

        print "Error!: " . $e->getMessage() . "</br>";

    }

} catch( PDOExecption $e ) {

    print "Error!: " . $e->getMessage() . "</br>";

}

?>



When no exception is thrown, lastInsertId returns 0. However, if lastInsertId is called before calling commit, the right id is returned.
