TP5 find_in_set用法

$where[‘class_id‘] = [‘in‘, ‘$cid_all‘];
$where[‘id‘] = [‘in‘, $all_user_id];//或这样子
$where[‘title‘] = [‘like‘, ‘%php%‘];
$where[‘id‘] = [‘<>‘, $id];
$where[‘id‘] = [‘notin‘, $all_user_id];//不等于
 
 
//值为数字
$id=419;
$where[] = [‘exp‘,Db::raw("FIND_IN_SET($id,category)")];//category值为数字，例子：419,415,414
//值为字符串
$id值等于dfd 要注意‘引号
$where[] = [‘exp‘,Db::raw("FIND_IN_SET(‘$id‘,category)")];//category值为数字，例子：‘349/417/419‘,‘349/413/415‘,‘349/413/416‘

Db::name(‘menu‘)->where(‘FIND_IN_SET(:id,pid_all)‘,[‘id‘ => $id])->update([$field => $title]);

Db::table(‘think_user‘)
    ->where(‘find_in_set(1,sids)‘)
