php计算具有相同ID的数组行

Question

大家好，我有一个脚本循环将数据放入 CSV 文件的数组，我需要计算具有相同 ID 的行。

这是我的脚本，它循环数组并将其放入 csv 文件中以供导出。

public function fputToFile($file, $allexportfields, $object, $ae)
{
    if($allexportfields && $file && $object && $ae)
    {
        //one ready for export product
        $readyForExport = array();
        //put in correct sort order
        foreach ($allexportfields as $value)
        {
            $object = $this->processDecimalSettings($object, $ae, $value);
            $readyForExport[$value] = iconv("UTF-8", $ae->charset, $object[$value]);
        }
        //write into csv line by line
        fputcsv($file, $readyForExport, $ae->delimiter, $ae->separator);
    }
}

我试过用：

$numero_riga = array_count_values($readyForExport);

$readyForExport['numero_riga'] = $numero_riga;

但是因为它是一个多维数组，所以在 csv 文件 meabe 中没有打印出任何正确的值，你可以在下面的文本和截图中看到 csv 导出：

ID 行号

198 阵列 199 阵列 200 阵列 200 阵列 201 阵列 201 阵列 201 阵列 201 阵列 202 阵列 202 阵列 203 阵列 203 阵列 203 阵列 204 数组 204 数组 204 数组 204 数组 204 数组 205阵列 205阵列 205阵列 206 阵列 207 阵列 207 阵列 208 阵列 209 阵列

csv export

结果必须在下面的文本和屏幕截图中是这样的，您可以看到一列计算具有相同 ID 的行。

ID 行号

176 1 177 1 177 2 178 1 178 2 179 1 179 2 180 1 181 1 181 2 182 1 182 2 183 1 184 1 184 2 185 1 185 2 186 1 186 2 186 3

correct result

提前致谢。

编辑了来自 scaisEdge 的 whit 建议，但现在 csv 导出以一种奇怪的方式运行。我把截图贴在这里csv strange behaviour

现在我在 scaisEdge 的帮助下使用此代码，我认为我们已经接近解决方案。

             $cnt_row = 0;
             $match_id = -1;
            //put in correct sort order
            foreach ($allexportfields as $value)
            {
                if ( $value['id_order'] == $match_id){
                   $cnt_row++;
                } else {
                   $cnt_row =1;
                   $match_id  = $value['id_order'];
                }
                //$value['num_row'] = $cnt_row;
                print_r($cnt_row);
                $object = $this->processDecimalSettings($object, $ae, $value);
                $readyForExport[$value] = iconv("UTF-8", $ae->charset, $object[$value]);

            }

            $readyForExport['num_row'] = $cnt_row;

我在此处粘贴实际结果的屏幕截图：partially correct result 您可以看到现在在正确的列中打印一些值，但始终打印“4”...

试试这个：

<?php
class Yourclass {
    private $counter = null;

    public function fputToFile($file, $allexportfields, $object, $ae)
    {
            if($allexportfields && $file && $object && $ae)
            {
                    //one ready for export product
                    $readyForExport = array();

                    //put in correct sort order
                    foreach ($allexportfields as $value)
                    {
                            $object = $this->processDecimalSettings($object, $ae, $value);
                            $readyForExport[$value] = iconv("UTF-8", $ae->charset, $object[$value]);
                    }

                    $this->counter[$readyForExport['id_order']] = (!empty($this->counter[$readyForExport['id_order']])) ? ++$this->counter[$readyForExport['id_order']] : 1;
                    $readyForExport['orderLine'] = $this->counter[$readyForExport['id_order']];

                    fputcsv($file, $readyForExport, $ae->delimiter, $ae->separator);
            }
    }
}

您应该检查 id_order 何时更改而不是数组中元素的数量

public function fputToFile($file, $allexportfields, $object, $ae)
{
    if($allexportfields && $file && $object && $ae)
    {
        //one ready for export product
        $readyForExport = array();
        //put in correct sort order
        $cnt_row = 0;
        $match_id = '';
        //cicle through the array
        foreach ($allexportfields as $value)
        {
            if ( $match_id == $value['id_order']){
               $cnt_row++;
            } else {
               $cnt_row =1;
               $match_id  = $value['id_order'];
            }
            $value['num_row'] = $cnt_row;
            $object = $this->processDecimalSettings($object, $ae, $value);
            $readyForExport[$value] = iconv("UTF-8", $ae->charset, $object[$value]);

        }
        //write into csv line by line
        fputcsv($file, $readyForExport, $ae->delimiter, $ae->separator);
    }
}
