php - php中从二级路径获取所有zip文件

Question

我想从我的两层路径中获取所有 *.zip 文件，我做了两个 while 循环和 foreach 循环。我一直对数组有一些错误，例如“array_filter() [function.array-filter]:第一个参数应该是一个数组”。有人可以帮忙吗？

<?php
$dirs = array_filter(glob('*'), 'is_dir');
 while (list($key, $value) = each($dirs)) {
  $dirs_2 = array_filter(glob($value.'/*'), 'is_dir');
  while (list($key_2, $value_2) = each($dirs_2)) {
    foreach (array_filter(glob($value_2."/*.zip")) as $filename) {
        echo "$filename size " . filesize($filename) . "\n";
    }
   }
 }
?>

谢谢

您可以使用SplIterators为了这。 RecursiveDirectoryIterator目的是:

// create recursive directory iterator for zip folder
$directory_iterator = new RecursiveDirectoryIterator('/path/to/zip/files');´   
// required to iterate through results using foreach
$recusive_iterator = new RecursiveIteratorIterator($directory_iterator);
// filter only .zip files
$regex_iterator = new RegexIterator($recursive_iterator, '/^.*\.zip$/',
                          RegexIterator::GET_MATCH);

// iterate through results
foreach($regex_iterator as $file_info) {
    var_dump($file_info);
}
