How to retrieve the id of the last inserted row when using PDO in PHP?

Question

Example: I insert a row into the DB with this, using PHP\'s built in PDO:

$sql = \"INSERT INTO mytable (name, ok) VALUES (\'john\', \'1\')\";
$this->dbh-&         


        

Answer 1

If the id is an auto_increment, you can use PDO::lastInsertId :

Returns the ID of the last inserted row, or the last value from a sequence object, depending on the underlying driver.

So, in your case, something like this should do the trick :

$lastId = $this->dbh->lastInsertId();
