访问在PHP多级阵列的较低值 [英] Accessing lower values of multilevel array in PHP

问题描述

我有对象的PHP数组，想轻松搞定所有POST_ID值。我已经调查之类的东西array_values​​和真的不知道如何处理这个事情。是只使用一个for循环，每个POST_ID添加到另一个阵列的所有岗位IDS的最佳方式？

I have a PHP array of objects and would like to get all the post_id values easily. I have looked into things like array_values and am not really sure what to do with this. Is the best way to just use a for loop and add each post_id to another array with all the post ids?

感谢您的帮助！

[0] => stdClass Object
    (
        [post_id] => 70242
        [image_id] => 70244
        [large_image] => 0
    )

[1] => stdClass Object
    (
        [post_id] => 70327
        [image_id] => 70339
        [large_image] => 1
    )

[2] => stdClass Object
    (
        [post_id] => 70017
        [image_id] => 70212
        [large_image] => 1
    )

编辑：
我得到这个数组从Word preSS分贝的呼叫：

I am getting this array from a WordPress db call:

$q = <<<SQL
    SELECT post_id, image_id, large_image
    FROM $homepage_db
    ORDER BY position;
SQL;

$results = $wpdb->get_results($q);

然后 $结果大于

推荐答案

只需使用的foreach 循环

foreach($result_object as $item){

    $post_id_array[] = $item->post_id;

}
