如何在php中使用函數

Question

檢索數組中的文件結構我想從dynatree的php中的特定路徑中檢索這種類型的數組？ 如何以檢索文件和文件夾這樣的陣列...

children: [ 
     {title: "Item 1", key: "node1"}, 
     {title: "Folder 2", isFolder: true, key: "node2", 
      children: [ 
       {title: "Sub-item 2.1", key: "node2.1"}, 
       {title: "Sub-item 2.2", key: "node2.2"} 
      ] 
     }, 
     {title: "Item 3", key: "node3"} 
     ] 

我嘗試這個功能...

<?php 

     function getDirectory($path = '.', $level = 0) { 
      $ignore = array('cgi-bin', '.', '..'); 
      $dh = @opendir($path); 

      while (false !== ($file = readdir($dh))) { 
       if (!in_array($file, $ignore)) { 
       if (is_dir("$path/$file")) { 
        echo '<li id="key1" class="folder expanded">' . $file; 
        echo '<ul class="folder-content">'; 
        getDirectory("$path/$file", ($level + 1)); 
        echo '</ul>'; 
        echo '</li>'; 
        } 
       } 
      } 
     closedir($dh); 
    } 
    ?>

你可以試試這個功能：

function getDirectory($path = '.', $level = 1) 
{ 
    $result = array(); 
    $ignore = array('nbproject', 'src', '.', '..'); 
    $dh = @opendir($path); 

    $i = 0; 
    while($file = readdir($dh)) 
    { 
     if(!in_array($file, $ignore)) 
     { 
      if(is_dir($path.'/'.$file)) 
      { 
       $level++; 
       $singleResult = array('title'=>$file, 'isFolder'=>true, 'children'=>$this->getDirectory($path.'/'.$file, $level), 'key'=>'node'.$level); 
       $result[] = $singleResult; 
      } 
      else 
      { 
       $result[] = array('title'=>$file, 'key'=>'node'.$level.'.'.$i); 
      } 
     } 

     $i++; 
    } 

    closedir($dh); 

    return $result; 
} 

我用掃描這個功能我的目錄之一，它輸出：

當然，你需要自己實現將數組轉換爲json，只需要掃描目錄並給它適當的參數。
