使用RecursiveDirectoryIterator

Question

可能重複：
Displaying folders and making links of those folders

我試圖使用RecursiveDirectoryIterator創建一個簡單的文件瀏覽器，但似乎無法推測出來...任何請幫助？

$cwd = '/path/to/somewhere'; 
if(isset($_GET['path']) && is_dir($cwd.$_GET['path'])) { 
    $cwd .= $_GET['path']; 
} 

$dir = new RecursiveDirectoryIterator($cwd); 
$iter = new RecursiveIteratorIterator($dir, RecursiveIteratorIterator::SELF_FIRST); 
while($iter->valid()) { 
    // skip unwanted directories 
    if(!$iter->isDot()) { 
     if($iter->isDir()) { 
      // output linked directory along with the number of files contained within 
      // for example: some_folder (13) 
     } else { 
      // output direct link to file 
     } 
    } 
    $iter->next(); 
} 

不知道這是最好的方法，但我的印象是RecursiveDirectoryIterator比均執行opendir（）和水珠（）方法快下我。

Answer 1

SELF_FIRST和CHILD_FIRST作爲無關RecursiveDirectoryIterator但RecursiveIteratorIterator

如果運行

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir), RecursiveIteratorIterator::SELF_FIRST); 

foreach ($iterator as $path) { 
    if ($path->isDir()) { 
     print($path->__toString() . PHP_EOL); 
    } else { 
     print($path->__toString() . PHP_EOL); 
    } 

你會得到

...\htdocs\lab\stockoverflow\css 
...\htdocs\lab\stockoverflow\css\a.css 
...\htdocs\lab\stockoverflow\css\b.css 
...\htdocs\lab\stockoverflow\css\c.css 
...\htdocs\lab\stockoverflow\css\css.php 
...\htdocs\lab\stockoverflow\css\css.run.php 

如果將其更改爲RecursiveIteratorIterator::CHILD_FIRST

...\htdocs\lab\stockoverflow\css\a.css 
...\htdocs\lab\stockoverflow\css\b.css 
...\htdocs\lab\stockoverflow\css\c.css 
...\htdocs\lab\stockoverflow\css\css.php 
...\htdocs\lab\stockoverflow\css\css.run.php 
...\htdocs\lab\stockoverflow\css 

你能看出差別在於當前文件夾的位置嗎
