delete() destroy()删除数据的区别---ThinkPHP5（TP5）对数据库操作总结

1.删除 delete()  destroy()

T::where('id=1')->delete(1);

T::where('id','in',[2,3])->delete();

T::destroy('4,5');

Db::table('t')->delete(6);

Db::table('t')->delete([7,8]);

删除返回值：

delete()返回删除的条数，若一条没有删除则返回值为零

destroy（）返回true/false  ,若删除不纯在的记录，返回值依旧为true

Db::table('t')->destroy([9,10]);报以下错误

method not exist:think\db\Query->destroy

T::delete(1); 报以下错误

Non-static method think\Model::delete() should not be called statically
