fopen-无法打开流:权限被拒绝 [英] fopen - failed to open stream: Permission denied

问题描述

从桌面打开文件时是否可以将数据写入 CSV ?因为当用户提交表单时，我试图将某些输入数据写入 CSV ，但是当从桌面上打开文件时，却遇到了以上错误.关闭文件后，我的系统才会写入csv.

Is it possible to write data to CSV while the file is opened from desktop? Because I am trying to write some input data to CSV when user submit the form, but I am getting above error when the file is opened from my desktop. My system will only write to csv when I close the file.

遇到行 $ fp = fopen("C:\ Users \ lenovo \ Desktop \ sample.csv"，"w");

推荐答案

通过在文件所在文件夹的终端上使用以下命令来更改文件sample.csv的权限-

Change the permission of the file sample.csv by using the following command on the terminal in the folder where the file is-

chmod 777 sample.csv
