tp5：insertGetId方法新增数据并返回主键值使用getLastInsID方法：Db::name('user')->insert($data);$user--...
数据库存取微信昵称特殊符号时，可以使用下面代码，
TP5字段值加1原始的办法 setInc && se
$count = Db::name('member')->where("id",$id)->count(); 用count()就可以
OR查询$where['userid|uname'] = ['like',"%".$keyword."%"];$list = Db::name('member')->where($where)->order('mid desc')->limit(15)->select();
$filter['field'] = ['neq','not null']; //不为空$filter['field'] = null; //null或者$filter[''] = [Db::raw('field IS NULL')]$filter[''] = [Db::raw('field IS NOT NULL')]
项目中mysql 日期字段是字符串形式，要求实现根据日期筛选字段public function test(){ $db = M ( 'log_alert' ); $date1="2014-06-17T16:13:23.614+08:00"; $date2="2014-06-17T16:13:25.714+08:00"; $map['time'] = array(array(
$list=user::where($search)->order('iddesc')->paginate(10,false,['query'=>request()->param()])'currentPage'=>$list->curren
try { ... } catch(\Exception $e){ $this->error($e->getMessage()); }
按照字段sort的1,3,2来排序 1,3,2不需要用引号->orderRaw("field(sort,1,3,2)")1后面sort相同的情况下,可以继续定义别的排序方式->orderRaw("field(sort,1,2,3),create_time desc")
thinkphp5内报错Call to a member function toArray() on array使用场景 使用模型查询后，想获取不包含对象内容的数组结构的结果。使
$arr = [ [ "id" =>"11", "money" => "111", ],[ "id" => "12", "money" => "222", ]];我要计算
利用正则拆分$str = "php如何将字 符串中322的字母数字Asf f45d和中文_分割？";$arr = preg_split("/([a-zA-Z0-
location / { if (!-e $request_filename){ rewrite ^(.*)$ /index.php?s=$1 last; break; }}
截图：在model里面添加protected$resultSetType='collection';classKemuextendsModel{protected$resultSetType='collection';}
数据查询：Db::name('CmsA
原生SQL语句进行查询示例：Db::table('user')->where('find_in_set(1,ids)')->select();查询表达式示例Db::table('user')->where('exp','FIND_IN_SET(1,ids)')->select();数组条件查询形式示例：$where[]=['exp','FIND_IN_SET(2,ids)'
