PHP foreach循环多个对象？ [英] PHP foreach loop on multiple objects?

问题描述

我使用PHP / codeigniter，通常循环查询结果我会做这样的：

I am using PHP/codeigniter, and typically to loop over query results I would do something like this:

<?php foreach($data as $row):?>
//html goes here
<?php endforeach;?>

但是，我有另一个对象数组， $ data2 ，与 $ data 具有相同数量的对象：是否有任何有效的PHP语法，将允许我同时访问 rows 在同一个循环中的两个对象使用 foreach 语句？我知道我可以通过访问数组的空格，定期循环的循环，但这不会那么干净。

But, say I have another object array, $data2, with the same number of objects as $data: is there any valid PHP syntax that would allow me to simultaneously access rows on both objects within the same loop using the foreach statement? I know I could do this with a regular for loop by accessing the indeces of the arrays, but this wouldn't be as clean.

推荐答案

你可以这样：

<?php foreach($data as $key => $row): $row2 = $data2[$key]; ?>
//html goes here
<?php endforeach;?>

这将有效地使您能够同时循环两个数组。

Which would effectively enable you to loop both arrays at the same time.
