php对csv文件的读取,写入,输出下载操作详解
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";
