Answer 1

使用 firstOrCreate 方法:

$user = User::firstOrCreate(['name' => 'John Doe']);

如果您想知道用户是否已创建或已获取，请检查 wasRecentlyCreated 属性:

if ($user->wasRecentlyCreated) {
    // "firstOrCreate" didn't find the user in the DB, so it created it.
} else {
    // "firstOrCreate" found the user in the DB and fetched it.
}
