我在三种不同的情况下插入有关汽车的信息，首先它转到自动，其中仅包含 4 行基本年份制造型号和价格，并且唯一的 ID 由 mysql 自动设置。伟大的。现在我如何返回为该实例设置的 id，以便我可以使用它将其插入到图片和属性的其他两个实例中？
$toauto = "INSERT INTO auto(year, make, model, mileage, price)
VALUES (?, ?, ?, ?, ?)";
/*
//sql for inserting into auto
$toattributes = "INSERT INTO attributes(auto_id,
bodystyle, enginesize, cyl, hp, fuel, transmission, shifts, od, cd, mp3, dvd,
gps, sound_system, sradio, tachometer, clock, trip, eweather, digitalboard, rwd,
fwd, awd, fxf, cruisecontrol, tiltsteering, ac, removabletop, keyless, airbags,
alloy, trunkantitrap, ewindows, emirrors, eseat, elocks, antitheft, leadheadlights

VALUES ($autoid, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?,
?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
//sql to insert into the pictures
$topictures = "INSERT INTO auto(year, make, model, mileage, price)

*/
print_r($auto);
print_r($paths);
//$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
//inserting to auto
$sth = $dbh->prepare($toauto);
$final = array_merge(array_values($auto));
$sth->execute($final);
/*

$sth->execute($final);

行名称是auto_id
