php数据库查询循环遍历

php数据库查询循环遍历

在php 的数据看查询中,我们往往会遇到很多的需要用到 foreach 循环遍历的地方。

而且会需要在循环里加上数据的查询操作。

例如:我们在查询文章的时候需要转换时间格式,并获取到文章的类型

$list = db(‘article’)

->alias(‘a’)

->leftJoin(‘user u’,’a.author_uid = u.id’)

->field(‘a.*,u.name’)

->where(‘title’, ‘like’, “%” . $key . “%”)

->order(‘a.id desc’)

->paginate(array(‘list_rows’ => $pageSize, ‘page’ => $page))

-> toArray ();

$arr=array(‘仅自己可见’,’公开’);

foreach ($list[‘data’] as $k=>$v){

$list[‘data’][$k][‘is_show’]=$arr[$v[‘is_show’]];

$list[‘data’][$k][‘add_time’] = date(‘Y-m-d H:i:s’,$v[‘add_time’]);

$list[‘data’][$k][‘type’] = db(‘article_type’)->where(‘id’,$v[‘type’])->value(‘name’);

}
