Объединить / объединить (не уверен, что мне нужно?) Массив php, если ключи [любые] [0] совпадают

Question

Используя следующий код, я могу преобразовать загруженный CSV-файл в массив php.

    <?PHP
function readCSV($csvFile){
    $file_handle = fopen($csvFile, 'r');
    fgetcsv($file_handle);
    fgetcsv($file_handle);
    fgetcsv($file_handle);
    while (!feof($file_handle) ) {
        $line_of_text[] = fgetcsv($file_handle, 1024);
    }
    fclose($file_handle);
    return $line_of_text;
}


// Set path to CSV file
$csvFile = 'test.csv';

$csv = readCSV($csvFile);
?>

Затем я могу просмотреть массив на своей странице с помощью ..

<code><?php echo '<pre>';
print_r($csv);
echo '

'; ?>

Это выводит массив следующим образом (выглядит как реальные данные, но был анонимным) ..

    <!-And so on.....>

Если вы посмотрите на [0], [1] & [2] вы увидите, что все они являются частью одного и того же номера записи о продажах (поэтому [0] [0], [1] [0] & [2] [0] - это одно и то же число) (но элементы [3] [ 0] и [4] [0] - отдельные заказы / разные номера). (помните, что это всего лишь пример, данные меняются, может быть сотни заказов и может быть 1 или несколько элементов на номер заказа.)

Я хотел бы объединить массивы для заказов с одинаковыми номер записи о продаже [любой] [0]

Так что-то вроде ....

если [любой] [0] совпадают друг с другом, то объединить массив

Это будет означают, что вся информация для номера заказа, который соответствует, будет в 1 массиве на номер заказа.

Я хочу сохранить все данные (игнорировать пробелы), но объединить их / объединить в соответствующий массив верхнего уровня как суб массивы так, например .. если [1] [0] соответствует [2] [0], все данные от [2] [0] до [2] [51] (которые не являются пустыми или одинаковыми) должны быть добавлены на [1], так что это становится как ...

Я надеюсь, что это имеет смысл, и это то, что я думаю, мне нужно.

Чего я пытаюсь добиться, так это сделать «для каждого l oop» для каждого массива верхнего уровня, чтобы я мог создать страницу счета-фактуры, где я мог бы использовать каждый массив верхнего уровня как отдельная страница счета / заказа в разметке html для этой страницы.

Answer 1

Пожалуйста, попробуйте следующий код. Это работает.

<?php

            $tmp = fgetcsv($file_handle, 1024);

            if (isset($line_of_text[$tmp[0]])) {
                foreach ($tmp as $k => $v) {

                    if (array_key_exists($k, $line_of_text[$tmp[0]])) {
                        if (!is_array($line_of_text[$tmp[0]][$k])) {
                            $kVal = $line_of_text[$tmp[0]][$k];

                            $line_of_text[$tmp[0]][$k] = [];

                        $line_of_text[$tmp[0]][$k] = array_filter($line_of_text[$tmp[0]][$k]);

        fclose($file_handle);
        return array_filter(array_values($line_of_text));

    $csv = readCSV($csvFile);

Answer 2

Вы можете обрабатывать массив следующим образом:

$arr = [];
//$csv is your array
foreach($csv as $key => $value){
  $arr[$value[0]][] = $value;  
}
print_r($arr);

этот код добавит все вложенные массивы с тем же [0] -ым индексом.

, затем вы можете использовать другие функции php для создания Ваш массив уникален.

Если вы хотите получить результат с объединенными массивами, попробуйте следующий код.

$arr = [];
//$csv is your array
foreach($csv as $key => $value){
  if(!array_key_exists($value[0],$arr)){
    $arr[$value[0]] = [];
  }
  $arr[$value[0]] = array_merge($arr[$value[0]],$value);  
}
print_r($arr);

Я не проверял код, поэтому, если есть, исправьте любую ошибку.

Answer 3

Я думаю, что это может привести к чему-то другому, чем вам нравится, если может произойти следующая ситуация:

Допустим, у нас есть 3 записи, подобные этой:

$original = [0] => [
  [0] => 'id0',
  [1] => 'name 0',
  [2] => 'street 0'
],
[1] => [
  [0] => 'id0',
  [1] => 'name 1',
  [2] => 
],
[2] => [
  [0] => 'id0',
  [1] =>,
  [2] => 'street 2'
]

, в результате вы получите следующая структура, если я следую тому, что, как я думаю, вы имеете в виду:

$new = [0] => [
  [0] => 'id0',
  [1] => [
    [0] => 'name 0',
    [1] => 'name 1'
  ],
  [2] => [
    [0] => 'street 0',
    [1] => 'street 2'
  ]
]

вы можете видеть, что $ new [0] [1] [1] от $ original [1] [1], в то время как на та же позиция в массиве $ new [0] [2] [1] происходит из $ original [2] [2]

Я думаю, проблема в том, что вы теперь выравниваете $ original [X] [1] с $ original [X] [2], если вы печатаете это в какой-то таблице / обзоре, они оказываются рядом друг с другом, но не связаны между собой.

==

Что касается того, как Чтобы решить вашу проблему, я бы предложил что-то вроде этого:

function readCsv($csvFileName) {
    $file_handle = fopen($csvFile, 'r');
    $records = [];
    fgetcsv($file_handle);
    while (!feof($file_handle) ) {
