set permissions for all files and folders recursively
提问by testing
I want to recursively set the folder and file permissions. Folders should get 750 and files 644. I found thisand made some adaptions. Would this one work?
我想递归设置文件夹和文件权限。文件夹应该是 750，文件应该是 644。我找到了这个并做了一些调整。这个能用吗？
<?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?
为什么不为此使用查找工具？
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，它比 opendir 和 while 循环更干净。
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:
这是经过测试的，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);
?>

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，我修复了这个案例。
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);
}

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__));
