本文介绍了phalcon-如何循环通过关联(数组)模型:: find();输出键的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想遍历model :: find结果的列. 我认为可能的是将返回的对象强制转换为数组，以便能够遍历各列，但这是行不通的.

I want to loop through the columns of the model::find results. What I thought was possible is to cast the returning object to an array to be able to loop throught the columns, but that does not work.

这是我的 控制器代码:

Here is my Controller code:

<?php class ManageController extends ControllerBase { public function indexAction() { $this->view->setVar("pages",(array) Pages::find()); } }

并查看代码:

{% for key,value in pages %} <p>key: {{key}}</p> {% endfor%}

任何帮助都是有用的

推荐答案

使用它；

<?php class ManageController extends ControllerBase { public function indexAction() { $this->view->setVar("pages", Pages::find()); } }

并查看代码:

{% for page in pages %} {# in this case the key is just "0,1,2,3..." #} {# so we use the loop index (or loop.index0 for zero based) #} <p>This is the page #{{ loop.index }}</p> <p>{{ page.title }}</p> {% endfor%}

但是，如果您确实还需要遍历各个键，请使用:

But if you really need to loop through the keys too, use:

{% for key, value in items %} Key: {{ key }} Value: {{ value }} {% endfor%}
