无法在Ubuntu上使用PHP写入文件 [英] Having trouble writing to a file with PHP on Ubuntu

问题描述

我在Ubuntu 14.04上运行PHP 5.5.9。我无法写入文件。我觉得这必须是一个文件权限问题，因为我敢肯定代码是正确的。我登录的用户有权写入我想要写入的文件夹，但我不确定本地主机是否可以。我不确定本地用户的名字是为了使用 chmod 。我尝试使用 chmod 777 -R / var / www / html ，脚本仍然无法写入到我的目标文件夹，其路径的/ var / www / html等/项目/ MD_ScrapingTool /文件。这是我的代码：

  $ file ='filetest.txt'; 
 if（$ handle = fopen（$ file，'w'））{
 $ content =123\\\
456; 
 fwrite（$ handle，$ content）; 
 fclose（$ handle）; 
} else {
 echo无法打开写入文件。 
 
  

解决方案

已经知道了。以下是解决任何有同样问题的人：


因为localhost属于 www-data 组，所以我刚添加了我的

  sudo usermod -a -G www-data my_username 
  
  
 $ b 然后，我将文件夹添加到组中。
  sudo chgrp -R www-data / var / www 
  
然后，我给写权限www-data group。
  sudo chmod -R g + w / var / www 
  
这对我没有任何其他问题。谢谢！
 
I am running PHP 5.5.9 on Ubuntu 14.04. I'm having trouble writing to a file. I feel like this has to be a file permissions problem because I'm pretty sure the code is correct. The user that I'm logged in as has permissions to write in the folders that I am trying to write into, but I'm not sure if the localhost does. I'm not sure what the name of the localhost user is in order to use chmod. I tried using chmod 777 -R /var/www/html and the script is still is not able to write to my target folder, which has the path /var/www/html/Projects/MD_ScrapingTool/files. Here is my code:
$file = 'filetest.txt';
if($handle = fopen($file, 'w')) {
    $content = "123\n456";
    fwrite($handle, $content);
    fclose($handle);
} else {
    echo "Could not open file for writing.";
}

解决方案
After some more research, I've got it figured out. Here is the solution for anyone having the same problem:


Since localhost belongs to the www-data group, I just added my user to that group.
sudo usermod -a -G www-data my_username
Then, I added the folder to the group.
sudo chgrp -R www-data /var/www
Then, I gave write permissions to the www-data group.
sudo chmod -R g+w /var/www
This worked for me without any other issue. Thanks!
