我目前正在向支付系统添加购买历史记录部分，该系统是用PHP(codeigniter框架)和mysql构建的。付款历史记录部分的想法是所有客户购买都按日期分组在一起，因此最终 HTML 看起来与此类似，
我的问题是我可以毫无问题地从数据库中获取数据，但是我如何循环它以便显示购买日期，然后显示与该日期相关的购买等等。
编辑 - 从数据库返回的数组的打印，抱歉，大小

基本上每次有新数据时，我都需要列出其下数组的内容，如果两个数组具有相同的数据，则将它们列在一个数据下，例如，
10-07-30
结果1
2
3
28-7-10
4
5
最佳答案
使用 CodeIgniter，循环查询结果的一种方法如下:
//if your doing your queries in a controller
$data['query']=$this->db->query('SELECT * FROM purchases WHERE clientID=5');
//or if using models
$data['query']=$this->pmnt_model->getPmnts();
//view
foreach($query result() as $row){
echo $row->date;
}
$query变量是mysql查询返回的结果数组。可以通过 -> 运算符访问这些对象。
参见http://codeigniter.com/user_guide/database/results.html了解更多信息。
