Question

我有一个php脚本，正在输出一个类似以下内容的json响应（如果重要的话，下面的响应是通过一个测试ajax调用输出的）---

{
  "type": "the type",
  "typesm": "type of",
  "entries": [
    {
      "title": "title one",
      "body": "Original text",
      "image": "image 1 url",
      "time": "1558532690",
      "meta": {
        "mainColor": "#100a0e",
        "adSpace": null
      }
    },
    {
      "title": "title two",
      "body": "Original text",
      "image": "image 1 url",
      "time": "1558515409",
      "meta": {
        "mainColor": "#100a0e",
        "adSpace": null
      }
    },

因此，在我的entries中，我有body和image的重复值，但其他一切似乎都没问题。

在我的脚本中，例如，我正在输出我的值-

$entries = $result->entries;

foreach ($entries as $ent){
echo $ent->image;
echo $ent->title;
echo $ent->body;
}

我的问题是我不想输出任何重复数据的条目，无论标题是否不同。如果图像和正文与另一个条目重复，那么我想跳过它。

我该如何实现？

来自php print_r的精确JSON响应结构-

stdClass Object
(
    [type] => game
    [typesm] => br
    [entries] => Array
        (
            [0] => stdClass Object
                (
                    [title] => Hang Time Bundle
                    [body] => Score big when you cop the Hang Time Bundle, available now in the Item Shop. Unlock new Styles with Creative Mode Challenges.
                    [image] => https://imageurl.jpeg
                    [time] => 1558532690
                    [meta] => stdClass Object
                        (
                            [mainColor] => #100a0e
                            [adSpace] => 
                        )

                )

            [1] => stdClass Object
                (
                    [title] => Hang Time Set
                    [body] => Score big when you cop the Hang Time Bundle, available now in the Item Shop. Unlock new Styles with Creative Mode Challenges.
                    [image] => https://imageurl.jpeg
                    [time] => 1558515409
                    [meta] => stdClass Object
                        (
                            [mainColor] => #100a0e
                            [adSpace] => 
                        )

                )

您可以使用array_column将条目与数组关联，并删除重复项。

$json = 'json string';
$arr = json_decode($json, true);
$arr['entries'] = array_column($arr['entries'], null, 'body');


foreach ($arr['entries'] as $ent){
    echo $ent['image'];
    echo $ent['title'];
    echo $ent['body'];
}

这样，当您循环输出时，只有唯一的值。

您也可以使用array_unique，但是将数组关联起来可以通过其他方式带来好处。

如果要根据图像和正文删除重复项，则循环数组并创建复合关联键。

$json = 'json string';
$arr = json_decode($json, true);
foreach($arr['entries'] as $e){
    $ent[$e['body'] . " " . $e['image']] = $e;
}

$ ent现在是具有唯一值“ entries”的新数组

foreach ($ent as $e){
    echo $e['image'];
    echo $e['title'];
    echo $e['body'];
}

PHP API从不同的键JSON中删除重复的值
