1、删除数据 delete

delete 方法返回影响数据的条数，没有删除返回 0

public function index(){

# 根据条件删除数据

$delete = Db::table('shop_goods')->where('id',1)->delete();

print_r($delete);

# 删除主键为2的数据

$delete = Db::table('shop_goods')->delete(2);

print_r($delete);

# 删除整表数据

$delete = Db::table('shop_goods')->delete(true);

print_r($delete);

}

2、软删除 useSoftDelete

业务数据不建议真实删除数据，TP系统提供了软删除机制

public function index(){

# 软删除

$delete = Db::table('shop_goods')->useSoftDelete('status',3)->delete();

print_r($delete);

}
