目录迭代器自定义阵列

Question

我试着去生产这种用于JSTree

[ 
      {"id":2,"text":"Child node 1"}, 
      {"id":3,"text":"Child node 2"}, 
      { 
       "text" : "Root node", 
       "state" : { "opened" : true }, 
       "children" : [ 
        { 
         "text" : "Child node 1", 
         "state" : { "selected" : true }, 
         "icon" : "jstree-file" 
        }, 
        { "text" : "Child node 222", "state" : { "disabled" : true } } 
       ] 
      } 
     ] 

我试着通过使用DirectoryIterator

创建此我得到了以下关闭PHP网站

$ritit = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory), FilesystemIterator::SKIP_DOTS); 
    $r = array(); 
    foreach ($ritit as $splFileInfo) { 


     $path = $splFileInfo->isDir() 
     ? array($splFileInfo->getFilename() => array()) 
     : array($splFileInfo->getFilename()); 

     for ($depth = $ritit->getDepth() - 1; $depth >= 0; $depth--) { 
     $path = array($ritit->getSubIterator($depth)->current()->getFilename() => $path); 
     } 

     $r = array_merge_recursive($r, $path); 

    } 

的此输出

阵列 （ [] =>阵列 （ ）

[..] => Array 
(
) 

[0] => Christmas.docx 
[test1] => Array 
    (
    ) 

[test2] => Array 
    (
    ) 
) 

我试了一下修改这个

$k = array(); 
foreach ($ritit as $splFileInfo) { 
    //skip if its '.' or '..' 
    if ($splFileInfo->getFilename() === '.' || $splFileInfo->getFilename() === '..') { 
    continue; 
    } 

    //if is dir 
    if($splFileInfo->isDir()) { 

     $path[] = array("text" => $splFileInfo->getFilename(), "children" => array()) ; 

     } else { 
      $path[] = array("text" => $splFileInfo->getFilename()); 

    }   

    for ($depth = $ritit->getDepth() - 1; $depth >= 0; $depth--) { 
    $path["children"] = array($ritit->getSubIterator($depth)->current()->getFilename() => $path); 
    } 

    $k = array_merge_recursive($k, $path); 

} 

而这种输出

Array 
(
    [test2] => Array 
     (
     ) 

    [0] => Array 
     (
      [text] => Christmas.docx 
     ) 

    [1] => Array 
     (
      [text] => Christmas.docx 
     ) 

    [2] => Array 
     (
      [text] => test1 
      [children] => Array 
       (
       ) 

     ) 

    [3] => Array 
     (
      [text] => Christmas.docx 
     ) 

    [4] => Array 
     (
      [text] => test1 
      [children] => Array 
       (
       ) 

     ) 

    [5] => Array 
     (
      [text] => test2 
      [children] => Array 
       (
       ) 

     ) 

) 

请你能帮助我与我”米意味着要做的迭代通过文件结构并返回一个数组，我可以在开始的帖子转换成json？

我有现在这样：

function requestAccountFolderStructure($dir) { 
    $list = array(); 
    $path = $dir; 
    $i = 0; 
    foreach (new DirectoryIterator($path) as $file) { 
     if ($file->isDot()) 
      continue; 

     if ($file->isDir()) { 
      $record = array(); 
      $record['id'] = $i; 
      $record['text'] = $file->getFilename(); 
      $record['children'] = array();    
      $record['path'] = $file->getPathInfo()->getFilename();    
      if (is_dir($dir . '/' . $file)) { 
       $record['children'] = requestAccountFolderStructure($dir . '/' . $file); 
      } 
      $list[] = $record; 
      $i++; 
     } 

    } 
    return $list; 
} 

    $dir = 'folder/'; 
    $directories = requestAccountFolderStructure($dir); 

    foreach($directories as $directory){ 
     //if(count($directory['children'] === 1)){ 
      $dir = new DirectoryIterator('folder/' . $directory['text']); 
      foreach ($dir as $fileinfo) { 
     if (!$fileinfo->isDir()) { 
        $directories[$directory['id']]['children'][] = array("text" => $fileinfo->getFilename(),"icon" => "jstree-file"); 
     } 
      } 
     //}  
    } 

    print_r(json_encode($directories)); 

这对我产生

[{"id":0,"text":"test1","children":[{"text":"1.docx","icon":"jstree-file"}],"path":"folder"},{"id":1,"text":"test2","children":[{"id":0,"text":"New folder","children":[],"path":"test2"},{"text":"2.txt","icon":"jstree-file"}],"path":"folder"}] 

我只需要图出去马国王它的子文件夹，子迭代现在

此代码

$fileData = convertDirectoryToArray(new DirectoryIterator('folder/')); 

function convertDirectoryToArray(DirectoryIterator $dir) 
{ 
    $data = array(); 
    foreach ($dir as $node) 
    { 
    if ($node->isDir() && !$node->isDot()) 
    { 
     $test = array(); 
     $test['text'] = $node->getFilename(); 
     $test['children'] = convertDirectoryToArray(new DirectoryIterator($node->getPathname())); 

     $data[] = $test; 
    } 
    else if ($node->isFile()) 
    { 
     $test= array(); 
     $test['text'] = $node->getFilename(); 
     $test['icon'] = "jstree-file"; 
     $data[] = $test; 
    } 
    } 
    return $data; 
} 

print_r(json_encode($fileData)); 

产生

[{"text":"Christmas.docx"},{"text":"test1","children":[{"text":"1.docx"}]},{"text":"test2","children":[{"text":"2.txt"},{"text":"New folder","children":[{"text":"4.txt"}]}]}] 

这正是我一直在寻找！
