我只有第 N 個(gè)級別數(shù)組返回，此函數(shù)返回所有子列表$arr = array(array('id'=>100, 'parentid'=>0, 'name'=>'a'),array('id'=>101, 'parentid'=>100, 'name'=>'a'),  array('id'=>102, 'parentid'=>101, 'name'=>'a'),  array('id'=>103, 'parentid'=>101, 'name'=>'a'),);$new = array();foreach ($arr as $a){    $new[$a['parentid']][] = $a;}$tree = createTree($new, array($arr[0]));print_r($tree);function createTree(&$list, $parent){    $tree = array();    foreach ($parent as $k=>$l){        if(isset($list[$l['id']])){            $l['children'] = createTree($list, $list[$l['id']]);        }        $tree[] = $l;    }     return $tree;}此函數(shù)返回?cái)?shù)組中的所有數(shù)據(jù)。此函數(shù)返回不能返回特定級別完成然后中斷并返回值
