php - 如果键 [any][0] 是相同的数字，则合并/组合（不确定我需要哪个？）php数组

Question

使用以下代码，我可以将上传的 CSV 文件转换为 php 数组。

    <?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);
?>

然后我可以在我的页面上查看数组..

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

这会按如下方式输出数组（看起来像真实数据，但已匿名）..

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

如果您查看 [0]、[1] 和 [2]，您会发现它们都是同一个销售记录编号的一部分（因此 [0][0]、[1][0] 和 [2][0]是相同的数字）（但项目 [3][0] 和 [4][0] 是单独的订单/不同的数字）。（请记住，虽然这只是一个示例，但数据会发生变化，可能有 100 个订单，每个订单号可能有 1 个或多个项目。）

我想合并具有相同销售记录编号的订单数组 [any][0]

所以像....

如果 [any][0] 相互匹配，则合并数组

这意味着匹配的订单号的所有信息将在每个订单号的 1 个数组中。

我想保留所有数据（忽略空白），但将它们合并/合并到匹配的顶级数组中作为子数组，例如..如果 [1][0] 匹配 [2][0] 中的所有数据 [ 2][0] 到 [2][51] （不是空的或相同的）应该添加到 [1] 上，这样它就变成了......

我希望这是有道理的，这就是我认为我需要的。

我想要实现的是为每个顶级数组创建一个“for each loop”，以便我可以制作一个发票页面，然后我可以在其中将每个顶级数组用作html中的单独发票/订单页面该页面的标记。

Answer 1

请尝试以下代码。它正在工作。

<?php
    function readCSV($csvFile)
    {
        $line_of_text = [];
        $file_handle = fopen($csvFile, 'r');
        while (!feof($file_handle)) {
            $tmp = fgetcsv($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]][$k] = array_filter($line_of_text[$tmp[0]][$k]);

                        if (count($line_of_text[$tmp[0]][$k]) == 1) {

            }

        }

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

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

    echo "<pre>";
    print_r($csv);

Answer 2

您可以像这样处理数组

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

此代码将附加所有具有相同第 [0] 索引的嵌套数组。

然后您可以使用其他 php 函数来使您的数组独一无二。

如果你想要一个合并数组的结果，你可以尝试下面的代码。

$arr = [];
//$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);

我还没有测试过代码，所以如果有任何错误请更正。

Answer 3

如果发生以下情况，我认为这可能会导致与您喜欢的不同：

假设我们有 3 条这样的记录：

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

如果我遵循我认为你的意思，你最终会得到以下结构：

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

你能看到 $new[0][1][1] 来自 $original[1][1]，而在数组 $new[0][2][1] 的相同位置来自 $original[ 2][2]

我认为问题在于您现在将 $original[X][1] 与 $original[X][2] 对齐，如果您在某种表格/概览中打印它们最终彼此相邻但不相关。

==

至于如何解决你的问题，我会建议这样的事情：

function readCsv($csvFileName) {
    $file_handle = fopen($csvFile, 'r');
    $records = [];
    fgetcsv($file_handle);
    while (!feof($file_handle) ) {
        $line = fgetcsv($file_handle, 1024);
        $id = $line[0];
        if (!$records[$id]) $records[$id] = [];
        $records[$id][] = $line;
    }
    fclose($file_handle);
    return $records;
}

function printCsvColumn($rowName, $sales) {
    $uniqueSales = array_unique($sales);
    $uniqueNotNullSales = array_filter($uniqueSales, 'strlen');
    foreach ($uniqueNotNullSales as $sale) {
        echo $rowName . ': ' . $sale[$rowName];
    }
}

function printCsv($records) {
    foreach ($records as $sales) {
        foreach ($sales[0] as $rowName=>$rowValue) {
            printCsvColumn($rowName, $sales);
        }
    }
}

如果您了解 OOP，您可以创建类和对象来为您表示此逻辑，这样您就不会以这种函数式的方式获取和迭代整个代码中的数据。
