csv file fopen php download code write copy right operate document of Detailed explanation read output

复制代码 代码如下:


    $file = fopen('text.csv','r');

    while ($data = fgetcsv($file)) {    //每次读取CSV里面的一行内容  
   //print_r($data); //此为一个数组,要获得每一个数据,访问数组下标即可
   $goods_list[] = $data;
    }
//print_r($goods_list);
echo $goods_list[0][1];
    fclose($file);  
?>


在实际工作中,很多时候需要把网站上的一些数据下载到CSV文件里,方便以后查看。
亦或者是用CSV进行一些批量的上传工作。
这个时候我们就需要对CSV进行读写操作。

CSV的读取操作

复制代码 代码如下:


    $file = fopen('D:/file/file.csv','r');   
    while ($data = fgetcsv($file)) {    //每次读取CSV里面的一行内容   
         print_r($data); //此为一个数组,要获得每一个数据,访问数组下标即可   
     }   
     fclose($file);   
?>  


CSV的写入操作

复制代码 代码如下:


  $fp = fopen('d:/file/file.csv', 'w');   
  fputcsv($fp,array('aaa','bbb','cccc'));   
  fputcsv($fp,array('mmm','yyy','haha'));   //fputcsv可以用数组循环的方式进行实现   
   fclose($fp);   
?>  


输出CSV(下载功能)

复制代码 代码如下:


     header("Content-Type: text/csv");   
     header("Content-Disposition: attachment; filename=test.csv");   
     header('Cache-Control:must-revalidate,post-check=0,pre-check=0');   
     header('Expires:0');   
     header('Pragma:public');   
    echo "id,areaCode,areaName/n";   
    echo "1,cn,china/n";   
    echo "2,us,America/n";   
?>


输出excel(下载功能)

header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:filename=php100.xls");
echo "id,areaCode,areaName/n";   
echo "1,cn,china/n";   
echo "2,us,America/n"
