Question

我正在尝试将CSV字符串解析为多维数组。我使用以下代码来执行此操作...

public function exportPartsAuthority($fileArray)
{       

    foreach ($fileArray as $filename => $fileContent) {
        $lines = explode("\n", $fileContent);
        $formatting = explode(",", $lines[0]);
        unset($lines[0]);
        $results = array();
        foreach ( $lines as $line ) {
           $parsedLine = str_getcsv( $line, ',' );
           $result = array();
           foreach ( $formatting as $index => $caption ) {
              if(isset($parsedLine[$index])) {
                 $result[$formatting[$index]] = trim($parsedLine[$index]);
              } else {
                 $result[$formatting[$index]] = '';
              }
           }
           $results[] = $result;
        }

        $var_str = var_export($results, true);
        $var = "<?php\n\n\$$values = $var_str;\n\n?>";
        file_put_contents('/home/apndev/public_html/output.txt', $var);

    }       
}

最终结果如下：

    'ShippingState' => '',
    'ShippingCountry' => '',
    'Vendor SKU' => '',
    'Line Code
' => '',
  ),
);

当我尝试回显$ results ['Vendor SKU']或var_dump它时，即使我看到上面设置的值，结果也是NULL。我还注意到顶部有一个语法错误（'$ = array'）。

话虽如此，我最终只是想从CSV中获取值，因为其中一些值将用于向第三方供应商发送订单信息。

有人能指出我如何修正输出的正确方向，这样我才能正确回显这些值吗？

谢谢！

Answer 1

使用内置的php函数来解析你的csv文件，而不是重新发明轮子。

str_getcsv

http://php.net/manual/en/function.str-getcsv.php

在手册页上有一个很好的例子，基本上可以满足您的需求：

$header = NULL;
    $data = array();
    if (($handle = fopen($filename, 'r')) !== FALSE)
    {
        while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE)
        {
            if(!$header)
                $header = $row;
            else
                $data[] = array_combine($header, $row);
        }
        fclose($handle);
    }
    print_r($data);

Answer 2

简单，使用预设的CSV读取方法：

$fp = fopen('data.csv', 'r');

$rows = array();
while (($row = fgetcsv($fp)) !== false)
    $rows[] = $row;

fclose($fp);

$rows将包含data.csv的所有数据作为二维数组。

有关详细信息，请参阅fgetcsv()。
