php从关联数组创建csv

我必须从下面的数组生成csv

Array
(
    [sku1] => Array
        (
            [bin1] => 10
            [bin2] => 5
            [bin3] => 10
        )

    [sku2] => Array
        (
            [bin2] => 10
            [bin10] => 9
        )

    [sku3] => Array
        (
            [bin3] => 7
        )

)

csv格式应如下所示：

sku1，bin1，10

sku1，bin2，10

sku2，bin2，10

sku2，bin10,9

sku3，bin3,7

如何存档

使用fputcsv函数尝试此示例并读取此链接

尝试：

尝试： //将标题设置为csv foramt中的自动下载文件

header("Content-Disposition: attachment; filename=\"demo.xls\"");
header("Content-Type: application/vnd.ms-excel;");
header("Pragma: no-cache");
header("Expires: 0");
$out = fopen("php://output", 'w');
//this is your data array to be converted in csv 

$result= 
array('sku1'=>array('bin1'=>10,'bin2'=>5,'bin3'=>10),'
sku2'=>array('bin2'=>10,'bin10'=>3),'sku3'=>array('bin3'=>7));

$final=array();
// now se are converting first array key in to node
foreach($result as $key=>$val){
// now se are converting second array key and value in to node
foreach ($val as $k=>$v){
// merging first array key and second array key values in to single array to 
//make a csv
$final[]=array($key,$k,$v);
}

}

foreach ($final as $data)
{
  //Now we are generating the csv from final array 
  fputcsv($out, $data,"\t");
}   
fclose($out);

你试过什么吗？你有代码吗？如何实现这一点-通过编写代码。使用fputcsv函数获取结果。因此，你想让我们编写你的代码吗？向我们展示您到目前为止尝试了什么？看看您能否格式化代码并添加更多关于代码功能的文本？我已经编辑了代码并解释了代码的功能

                    $array= [
                        'sku1' => [
                            'bin1' => 10,
                            'bin2' => 5,
                            'bin3' => 10
                        ]
                        ,
                        'sku2' => [
                            'bin2' => 10,
                            'bin10' => 9,
                        ],
                        'sku3' => [
                            'bin3' => 7
                        ]
                    ];

                    $fileContent=[];

                    foreach ($array as  $key =>$value1){
                         foreach ($value1 as $key2 => $value2){
                             $fileContent[]=[$key, $key2, $value2];
                         }
                    }


                    $fp = fopen('file.csv', 'w');

                    foreach ($fileContent as $fields) {
                        fputcsv($fp, $fields);
                    }

                    fclose($fp);

header("Content-Disposition: attachment; filename=\"demo.xls\"");
header("Content-Type: application/vnd.ms-excel;");
header("Pragma: no-cache");
header("Expires: 0");
$out = fopen("php://output", 'w');
//this is your data array to be converted in csv 

$result= 
array('sku1'=>array('bin1'=>10,'bin2'=>5,'bin3'=>10),'
sku2'=>array('bin2'=>10,'bin10'=>3),'sku3'=>array('bin3'=>7));

$final=array();
// now se are converting first array key in to node
foreach($result as $key=>$val){
// now se are converting second array key and value in to node
foreach ($val as $k=>$v){
// merging first array key and second array key values in to single array to 
//make a csv
$final[]=array($key,$k,$v);
}

}

foreach ($final as $data)
{
  //Now we are generating the csv from final array 
  fputcsv($out, $data,"\t");
}   
fclose($out);
