如何使RecursiveDirectoryIterator排除隐藏的文件夹 [英] How do I make a RecursiveDirectoryIterator exclude hidden folders

问题描述

我有一个类似的recursiveDirectoryIterator:

I have a recursiveDirectoryIterator like this:

$theme_iterator = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($theme_folder_path)
);
foreach ($theme_iterator as $file_object) {
   // Stuff
}

问题在于，它会迭代到.svn隐藏文件夹中.我该如何预防?

The problem is that it iterates into the .svn hidden folders. How can I prevent this?

我不能只在foreach中添加这样的内容，因为此时隐藏文件夹中的文件已全部存储在数组中，而且还不是全部被隐藏.

I can't just add something like this in the foreach because the files from the hidden folder are allready in the array at that point and they are not all hidden.

if (strpos($file_object, ".") ===0) {
    continue;
}

推荐答案

<?php
class RecursiveDotFilterIterator extends  RecursiveFilterIterator
{
    public function accept()
    {
        return '.' !== substr($this->current()->getFilename(), 0, 1);
    }
}

$iterator = new RecursiveIteratorIterator(
    new RecursiveDotFilterIterator(
        new RecursiveDirectoryIterator('.')
    )
);
foreach ($iterator as $x) {
    //do stuff
}
