PHP输出到CSV问题

Question

我正在尝试将数据输出到我已经成功完成的CSV文件中，但是发生的情况是，当您在开放式办公室中打开这些文件时，这些“出现在字段的开头和结尾。如何将其删除？

打开之前我的数据没有“”。

您不需要自己用逗号连接所有数据，这就是fputcsv()为您完成的工作。 您应该为它提供一个数组，其中每个元素都是一个不同的列，并且它将用逗号分隔它们。 您应该写：

// output the column headings
array_unshift($suppliers, 'Name'); // First column is botanical name, before suppliers
fputcsv($output, $suppliers);

// output the data rows
foreach ($names as $pl_botanical_name) 
  { 
    $nursery_plants = array($pl_botanical_name);

    for ($i = 0; $i < count($suppliers); $i++) 
      { 
        if(array_key_exists($i,$price_by_id)) 
          {       
            if(in_array($pl_botanical_name,$botanical_name[$i]))
              {
                $q = array_search($pl_botanical_name,$botanical_name[$i]);

                $ele = $price_by_id[$i][$q]; 
                $nursery_plants[] = $ele;

              } else { 
              $nursery_plants[] = '';
            }               
          } else { 
          $nursery_plants[] = ""; 
        }
      }
    fputcsv($output, $nursery_plants);
  }
