以递归方式设置所有文件和文件夹的权限

I want to recursively set the folder and file permissions. Folders should get 750 and files 644. I found this and made some adaptions. Would this one work?

我想以递归方式设置文件夹和文件权限。文件夹应该得到750和文件644.我发现了这个并做了一些改编。这个有用吗?

<?php

function chmod_r($Path) {
   $dp = opendir($Path);
   while($File = readdir($dp)) {
      if($File != "." AND $File != "..") {
         if(is_dir($File)){
            chmod($File, 0750);
         }else{
             chmod($Path."/".$File, 0644);
             if(is_dir($Path."/".$File)) {
                chmod_r($Path."/".$File);
             }
         }
      }
   }
   closedir($dp);
}

?>

Why don't use find tool for this?

为什么不使用find工具呢?

exec ("find /path/to/folder -type d -exec chmod 0750 {} +");
exec ("find /path/to/folder -type f -exec chmod 0644 {} +");

My solution will change all files and folder recursively to 0777. I use DirecotryIterator, it's much cleaner instead of opendir and while loop.

我的解决方案将递归地将所有文件和文件夹更改为0777.我使用DirecotryIterator,它更干净,而不是opendir和while循环。

function chmod_r($path) {
    $dir = new DirectoryIterator($path);
    foreach ($dir as $item) {
        chmod($item->getPathname(), 0777);
        if ($item->isDir() && !$item->isDot()) {
            chmod_r($item->getPathname());
        }
    }
}

This is tested and works like a charm:

这是经过测试,就像一个魅力:

<?

  header('Content-Type: text/plain');

  /**
  * Changes permissions on files and directories within $dir and dives recursively
  * into found subdirectories.
  */
  function chmod_r($dir, $dirPermissions, $filePermissions) {
      $dp = opendir($dir);
       while($file = readdir($dp)) {
         if (($file == ".") || ($file == ".."))
            continue;

        $fullPath = $dir."/".$file;

         if(is_dir($fullPath)) {
            echo('DIR:' . $fullPath . "\n");
            chmod($fullPath, $dirPermissions);
            chmod_r($fullPath, $dirPermissions, $filePermissions);
         } else {
            echo('FILE:' . $fullPath . "\n");
            chmod($fullPath, $filePermissions);
         }

       }
     closedir($dp);
  }

  chmod_r(dirname(__FILE__), 0755, 0755);
?>

Here improved version of the recursive chmod that skips files with the same permissions.

这里是递归chmod的改进版本,它跳过具有相同权限的文件。

<?

header('Content-Type: text/plain');

/**
* Changes permissions on files and directories within $dir and dives recursively
* into found subdirectories.
*/
function chmod_r($dir)
{
    $dp = opendir($dir);
    while($file = readdir($dp))
    {
        if (($file == ".") || ($file == "..")) continue;

        $path = $dir . "/" . $file;
        $is_dir = is_dir($path);

        set_perms($path, $is_dir);
        if($is_dir) chmod_r($path);
    }
    closedir($dp);
}

function set_perms($file, $is_dir)
{
    $perm = substr(sprintf("%o", fileperms($file)), -4);
    $dirPermissions = "0750";
    $filePermissions = "0644";

    if($is_dir && $perm != $dirPermissions)
    {
        echo("Dir: " . $file . "\n");
        chmod($file, octdec($dirPermissions));
    }
    else if(!$is_dir && $perm != $filePermissions)
    {
        echo("File: " . $file . "\n");
        chmod($file, octdec($filePermissions));
    }

    flush();
}

chmod_r(dirname(__FILE__));

I think yours won't go recursive in case of folders, I fixed this case.

我认为你的文件夹不会递归,我修复了这种情况。

function chmod_r($Path) {
    $dp = opendir($Path);
     while($File = readdir($dp)) {
       if($File != "." AND $File != "..") {
         if(is_dir($File)){
            chmod($File, 0750);
            chmod_r($Path."/".$File);
         }else{
             chmod($Path."/".$File, 0644);
         }
       }
     }
   closedir($dp);
}
