echo "Failed to connect to MySQL: " . $mysqli -> connect_error;
exit();
}
// Turn autocommit off
$mysqli -> autocommit(FALSE);
// Insert some values
$mysqli -> query("INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Peter','Griffin',35)");
$mysqli -> query("INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Glenn','Quagmire',33)");
// Commit transaction
if (!$mysqli -> commit()) {
echo "Commit transaction failed";
exit();
}
$mysqli -> close();
?>
$mysqli = new mysqli("localhost","my_user","my_password","my_db");
if ($mysqli -> connect_errno) {
echo "Failed to connect to MySQL: " . $mysqli -> connect_error;
exit();
}
// Turn autocommit off
$mysqli -> autocommit(FALSE);
// Insert some values
$mysqli -> query("INSERT INTO Persons (FirstName,LastName,Age)
VALUES ('Peter','Griffin',35)");
$mysqli -> query("INSERT INTO Persons (FirstName,LastName,Age)
