如何对 WP Rest API 返回的 multi-dimensional 数组进行排序？

Question

使用 WordPress REST API，我从外部获取帖子： https://example.com/wp-json/wp/v2/posts?orderby=date&order=desc&per_page=12

Body 结果：

[
    {
        "date": "2022-05-05T12:12:12",
        "link": "https://example.com/blog/132/",
        "title": {
            "rendered": "F: Title"
        }
    },
    {
        "date": "2022-04-04T12:12:12",
        "link": "https://example.com/blog/434/",
        "title": {
            "rendered": "E: Title"
        }
    },
    {
        "date": "2022-03-03T12:12:12",
        "link": "https://example.com/blog/324/",
        "title": {
            "rendered": "A: Title"
        }
    },
    etc...

]

我想按字母顺序排列标题。

最好的解决方案是什么？

我无法使用 WP_Query，因为帖子是从外部 WP API 来源提取的。

Answer 1

可能是这样的:

<?php
function cmp($a, $b)
{
    if ($a['title']['rendered'] == $b['title']['rendered']) {
        return 0;
    }
    return ($a['title']['rendered'] < $b['title']['rendered']) ? -1 : 1;
}

$ar = json_decode($yourJson, TRUE);
usort($ar, "cmp");

...

?>

Answer 2

使用此函数对任何数组进行排序

function array_sort($array, $on, $order = SORT_ASC)
{
    $new_array = array();
    $sortable_array = array();

    if (count($array) > 0) {
        foreach ($array as $k => $v) {
            if (is_array($v)) {
                foreach ($v as $k2 => $v2) {
                    if ($k2 == $on) {
                        $sortable_array[$k] = $v2;
                    }
                }
            } else {
                $sortable_array[$k] = $v;
            }
        }
        switch ($order) {
            case SORT_ASC:
                asort($sortable_array);
                break;
            case SORT_DESC:
                arsort($sortable_array);
                break;
        }


        foreach ($sortable_array as $k => $v) {
            $new_array[$k] = $array[$k];
        }
    }

    return $new_array;
}
