在TP框架中，数据插入

添加一条数据,返回添加成功的条数

$data = ['foo' => 'bar', 'bar' => 'foo'];
Db::name('user')->save($data);
// 或者
Db::name('user')->insert($data);

批量添加

$data = [
    ['foo' => 'bar', 'bar' => 'foo'],
    ['foo' => 'bar1', 'bar' => 'foo1'],
    ['foo' => 'bar2', 'bar' => 'foo2']
];
Db::name('user')->insertAll($data);

如果要返回批量添加是生成的主键ID，使用saveAll

$user = new User;
$list = [
    ['name'=>'thinkphp','email'=>'thinkphp@qq.com'],
    ['name'=>'onethink','email'=>'onethink@qq.com']
];
$res = $user->saveAll($list);

$ids = [];
if($res){
    foreach($res as $v){
        $ids[] = $v['id'];
    }
}
// 最后得到所有id
var_dump($ids);
