DirectoryIterator 忽略流浪同步文件夹中的目录 [英] DirectoryIterator ignoring directories in vagrant synced folders

问题描述

我正在使用 laravel/homestead vagrant box.当我尝试将 DirectoryIterator 用于同步文件夹时，它只返回点"条目 (..,.).

我的 vagrant 同步文件夹被称为 code(在 vmbox 中)，在这个目录中我有我的 vagrant 文件和项目代码，所以当我使用 DirectoryIterator 作为 /home/vagrant 它列出了所有没有问题的目录，包括 code 目录.但是当我将它用于 /home/vagrant/code 时，只显示点条目，其他目录被忽略.scandir() 正常工作，列出所有目录没有问题.

这是代码和输出:

foreach (new DirectoryIterator('/​​home/vagrant') as $fileInfo) {echo $fileInfo->getFilename() .<br>\n";}输出:....ssh.sudo_as_admin_successful.作曲家.当地的代码.config.bash_别名.wget-hsts.npm

foreach (new DirectoryIterator('/​​home/vagrant/code') as $fileInfo) {echo $fileInfo->getFilename() .<br>\n";}输出:...

foreach (scandir('/home/vagrant/code') as $fileInfo) {回声 $fileInfo.<br>\n";}输出:....流浪汉宅基地.yaml许可证.txt流浪档案后.sh别名垃圾桶作曲家.jsoncomposer.lock家园项目自述文件脚本源文件

解决方案

我对 vagrant 也有同样的问题.我调试了一下，发现问题在于同步文件夹的文件类型，而不是DirectoryIterator

问题

Vagrantfile - 文件夹同步配置问题

config.vm.synced_folder "/var/www/virtual/machine/folder", "/var/www/host/machine/folder"

在上述配置中，我没有为 sync 文件夹指定任何文件类型.因此，Vagrant 会自动为我的环境选择最佳的同步文件夹选项

解决方案

我已将同步文件夹文件类型更改为nfs"，从而解决了问题

Vagrantfile - 解决方案

config.vm.synced_folder "/var/www/virtual/machine/folder", "/var/www/host/machine/folder", type: "nfs"

注意

<块引用>

在使用 NFS 支持的同步文件夹之前，主机必须安装 nfsd，NFS 服务器守护程序.它预装在 Mac OS X 上，通常是在 Linux 上进行简单的软件包安装.

I'm using laravel/homestead vagrant box. When I try to use DirectoryIterator for synced folder it returns only the "dot" entries (..,.).

My vagrant synced folder is called code (in vmbox), inside this directory I have my vagrant files and project codes, so when I use DirectoryIterator for /home/vagrant it list all directories without problem including code directory. But when I use it for /home/vagrant/codeonly dot entries shows up, other directories is ignored. scandir() works normally and list all directories without a problem.

Edit: here is the code and outputs:

foreach (new DirectoryIterator('/home/vagrant') as $fileInfo) {
    echo $fileInfo->getFilename() . "<br>\n";
}
outputs:
.
..
.ssh
.sudo_as_admin_successful
.composer
.local
code
.config
.bash_aliases
.wget-hsts
.npm

foreach (new DirectoryIterator('/home/vagrant/code') as $fileInfo) {
    echo $fileInfo->getFilename() . "<br>\n";
}
outputs:
.
..

foreach (scandir('/home/vagrant/code') as $fileInfo) {
    echo $fileInfo. "<br>\n";
}
outputs:
.
..
.vagrant

解决方案

I had the same issue with vagrant. I debugged a little and found out the issue is the in the file type of the synced folder and not with the DirectoryIterator

Problem

Vagrantfile - folder sync config issue

config.vm.synced_folder "/var/www/virtual/machine/folder", "/var/www/host/machine/folder"

In the above configuration I did not specify any file type for the sync folder. because of that, Vagrant automatically choose the best synced folder option for my environment

Solution

I have changed the sync folder file type to "nfs" which solved the issue

Vagrantfile - solution

config.vm.synced_folder "/var/www/virtual/machine/folder", "/var/www/host/machine/folder", type: "nfs"

Note

Before using synced folders backed by NFS, the host machine must have nfsd installed, the NFS server daemon. This comes pre-installed on Mac OS X, and is typically a simple package install on Linux.
