在 PHP 中從順序數(shù)組創(chuàng)建嵌套數(shù)組

PHP

呼喚遠(yuǎn)方 2023-07-21 18:29:45

我需要在 PHP 中對數(shù)組進(jìn)行排序的幫助。我收到這些數(shù)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(huán)這些數(shù)組以將注釋數(shù)組（[1] 及以上）應(yīng)用到主數(shù)組 [0]?；蛘呶倚枰?[0] 之后的順序數(shù)組像這樣嵌套：

假設(shè)您提供的輸入數(shù)據(jù)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(jié)果是：

那是你要的嗎？

與您預(yù)期結(jié)果的唯一區(qū)別是，每一行都有“user_comments”數(shù)組，該數(shù)組可以為空，有一個或多個元素與此屬性丟失或被調(diào)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(diào)整為您發(fā)布的內(nèi)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(shù)據(jù)是否是評論或點贊。我這樣做是這樣的：如果數(shù)據(jù)包含comment_id，它是一條評論，如果它有l(wèi)ike_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(kuò)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(nèi)容分組user_comments到主線程下。我使用array_map將此過濾器應(yīng)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
