我们可以在PHP中进行这种类型的数组合并吗？如果可以，怎么样？

Question

那里有很多阵列功能，我尝试了几个甚至尝试做几次循环...我无法做到。 下面给出的数组是我的结果数组，相同的用户被多次插入，因为它们的值不同。改变所有机制将是一个好主意，但我在项目的最后阶段。如果有人可以这样做，请回复：

可以有多个用户具有相同的user_id。

Answer 1

未经测试，但您应该可以相对轻松地完成此操作。

如果您使用我认为唯一的user_id作为您的数组键，您将能够在需要时轻松访问用户的数据。

您还可以与现有密钥合并，或者只是在不存在时创建新的。

例如：

$output = array();
foreach ($input as $values) {
    $userId = $values->user_id;
    if (array_key_exists($userId, $output)) {
        // We've already added this user, so merge in openhouse
        $output[$userId]->openhouse = array_merge($output[$userId]->openhouse, $values->openhouse);
    } else {
        // We haven't added it yet, so just add everything
        $output[$userId] = $values;
    }
}

现在：查看您的示例数据，看起来您的openhouse数组包含相同的数据集，每个数组中都存在几个键，这些键区别于它们。如果是这种情况，您可能希望使用array_merge_recursive()。如果您发布一个更有用的示例数据示例，我可以使用它，但这应该可以让您开始。
