Thread Mode显示系统中的主次顺序的记录数，根据数组中的ID关联，不断的显示出子类的方法，觉得不错。记录下来分享。
<?php $node_cache = array(     array(         'id'=>1,         'name'=>'here',         'parentId'=>4     ),     array(         'id'=>2,         'name'=>'2here',         'parentId'=>0     ),     array(         'id'=>3,         'name'=>'3here',         'parentId'=>0     ),     array(         'id'=>4,         'name'=>'4here',         'parentId'=>2     ),     array(         'id'=>5,         'name'=>'5here',         'parentId'=>0     ),   array(         'id'=>6,         'name'=>'re:2here',         'parentId'=>2     ),   array(         'id'=>7,         'name'=>'re:re:2here',         'parentId'=>6     ),   array(         'id'=>8,         'name'=>'re:re:re:2here',         'parentId'=>7     ) ); $test_array = get_page_children(0, $node_cache,0); $last = "├─"; foreach($test_array as $key=>$val) {    $item = str_repeat(" │ ",$val['depth']);    echo $item.$last.$val['name']."<br/>\n";    $item = ''; } function &get_page_children($id, $node,$depth=0) {     global $node_cache;     if ( empty($node) )     {         $node = &$node_cache;     }     $depth++;     $tree_list = array();     foreach ($node as $leap)     {         if ($leap['parentId'] == $id)         {             $leap['depth'] = $depth - 1;             $tree_list[] = $leap;             if ( $children = get_page_children($leap['id'], $node,$depth))             {                 $tree_list = array_merge($tree_list, $children);             }         }     }     return $tree_list; } ?>
显示的效果如下：
├─2here
│ ├─4here
│ │ ├─here
│ ├─re:2here
│ │ ├─re:re:2here
│ │ │ ├─re:re:re:2here
├─3here
├─5here
