我需要在 PHP 中對數組進行排序的幫助。我收到這些數組，如下所示：Array ( [0] => Array ( [0] => Array ( [id] => 1 [username] => STLUserFolks [event_id] => 7e0a2faa-43c8-4552-b0ec-c4d0fa6c00d1 [event_on] => 2020-06-29 17:39:25.93432 [ent_pix] => [\"images/events/STLUserFolks/tammy1.jpeg\",\"images/events/STLUserFolks/tammy2.jpeg\",\"images/events/STLUserFolks/tammy3.jpeg\",\"images/events/STLUserFolks/tammy4.jpeg\",\"images/events/STLUserFolks/tammy5.jpeg\",\"images/events/STLUserFolks/tammy6.jpeg\"] [amount] => 20 [event_title] => Fun on vacation with friends. [event_type] => mix [event_details] => Saw Great and interesting sites today! ) ) [1] => Array ( [0] => Array ( [id] => 1 [username] => STLUserFolks [event_id] => debd6476-4f24-4d2c-9973-7c36d256079d [event_on] => 2020-07-09 05:39:10.588842 [ent_pix] => [\"images/events/STLUserFolks/680.JPG\",\"images/events/STLUserFolks/681.JPG\",\"images/events/STLUserFolks/682.JPG\"] [amount] => 25 [event_title] => Sexy Warm [event_type] => photos [event_details] => Feeling the sun on our faces. ) [1] => Array ( [id] => 1 [user_id] => 2 [username] => STLUserFolks [member_user] => spiffy_user [comment_text] => Amazing! you guys are simply amazing! [created_on] => 2020-07-10 15:04:46.480001 [comment_id] => c803294d-8483-43c9-a76b-4cba56795266 [event_id] => debd6476-4f24-4d2c-9973-7c36d256079d ) ) [2] => Array ( [0] => Array ( [id] => 1 [username] => STLUserFolks [event_id] => 3112f8ff-6119-48c4-810c-594585b5dc63 [event_on] => 2020-07-09 07:11:32.840511 [ent_pix] => 我需要能夠循環這些數組以將注釋數組（[1] 及以上）應用到主數組 [0]。或者我需要 [0] 之后的順序數組像這樣嵌套：

假設您提供的輸入數據位于 data.php 中：
<?php
$data = include('data.php');
$result = [];
foreach ($data as $row) {
$user = $row[0];
foreach ($row as $k => $element) {
if ($k === 0) {
$user = $element;
$user['user_comments'] = [];
} else {
$user['user_comments'][] = $element;
}
}
$result[] = $user;
}
var_dump($result);
結果是：

那是你要的嗎？
與您預期結果的唯一區別是，每一行都有“user_comments”數組，該數組可以為空，有一個或多個元素與此屬性丟失或被調用或user_comment如user_comments您的示例中所示。我相信這更加一致且更易于以編程方式使用，但如果需要，它也可以輕松調整為您發布的內容。
編輯評論和點贊。如果您想同時填寫 user_comments 和 user_likes，則必須檢測某些數據是否是評論或點贊。我這樣做是這樣的：如果數據包含comment_id，它是一條評論，如果它有like_id，它是一個喜歡。這是下面附加的簡單編輯。片段變成：
foreach ($row as $k => $element) {
if ($k === 0) {
$user = $element;
$user['user_comments'] = [];
$user['user_likes'] = [];
} else if (isset($element['comment_id'])) {
$user['user_comments'][] = $element;
} else if (isset($element['like_id'])) {
$user['user_likes'][] = $element;
}
}
如果需要，您稍后可以通過這種方式擴展它來處理不同的事件。

我使用該comment_text鍵來過濾給定線程的評論和非評論，并將所有內容分組user_comments到主線程下。我使用array_map將此過濾器應用于列表中的每個線程。
$flatThreads = \\your initial value
$nestedThreads = array_map(function($thread){
$notComments = array_filter($thread, function($thread_item){
return !isset($thread_item["comment_text"]);
});
$comments = array_filter($thread, function($thread_item){
return isset($thread_item["comment_text"]);
});
$mainItem = reset($notComments); //get first item that is not a comment
$mainItem["user_comments"] = $comments;
return $mainItem;
}, $flatThreads);
var_dump($nestedThreads); //what you requested
