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')";
$this->dbh->exec($sql);
I need the id of that row. How could I get that?
回答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();
