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

有那么多的阵列功能，我试过几个，甚至尝试做几个循环..我不能这样做。 下面给出的数组是我的结果数组，相同的用户多次插入，因为它们的值不同。改变所有机制将是个好主意，但是iam在项目的最后阶段。如果任何人都可以做到这一点，请回复：

可以有多个用户具有相同的user_id。

Answer 1

未经测试，但您应该能够相对容易地做到这一点。

如果你用我以为是你的数组键唯一的user_id，你就能当您需要方便地访问用户的数据。

你有额外的好处，可以合并现有的钥匙或只是创建新的，如果他们不存在。

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：看着它看起来像你的openhouse数组包含相同的一组数据，与一对夫妇键，在这里和存在每个数组中区分您的样本数据他们。如果是这种情况，则可以使用array_merge_recursive()代替。如果你发布了一个更有用的示例数据例子，我可以和它一起玩，但这应该让你开始。
