Foreach源PHP数组和对象 [英] PHP Foreach Arrays and objects

问题描述

我有对象的数组。
一的print_r看起来像这样

I have an array of objects. A print_r looks like this

Array
(
    [0] => stdClass Object
        (
            [sm_id] => 1
            [c_id] => 1
        )

    [1] => stdClass Object
        (
            [sm_id] => 1
            [c_id] => 2

        )

)

我真的在努力寻找一种方法，虽然循环的结果，并访问对象的元素。
如果任何人都可以给我任何指针，我将非常感激。

I am really struggling to find a way to loop though the results and access the object elements. If anyone could give me any pointers i would be extremely grateful.

在此先感谢
