Recursive problem of sub-column

static public function Get ($parentid = 0, $array = Array (), $level = 0, $add = 2, $repeat = ') {$str _repeat = ';        if ($level) {for ($j = 0; $j < $level; $j + +) {$str _repeat. = $repeat;    }} $newarray = Array ();    $temparray = Array (); foreach ((array) $array as $v) {if ($v [' parent_id '] = = $parentid) {$newarray [] = array (' ID ' =&G T $v [' id '], ' catalog_name ' = $v [' catalog_name '], ' catalog_name_alias ' + $v [' Catalog_name_alias '], ' parent_id ' =& Gt $v [' parent_id '], ' level ' = $level, ' sort_order ' + $v [' sort_order '], ' seo_keywords ' + $v [' seo_keywords '], ' s Eo_description ' + $v [' seo_description '], ' attach_file ' + $v [' attach_file '], ' attach_thumb ' = $v [' attach_th Umb '], ' status_is ' = $v [' status_is '], ' data_count ' = ' = ' $v [' data_count '], ' display_type ' + $v [' Display_type '] , ' menu_is ' = $v [' menu_is '], ' template_list ' + $v [' template_list '], ' acl_browser ' = $v [' Acl_browser '], ' acl_operate ' = $v [' acl_operate '], ' template_page ' and ' = ' $v [' template_page '], ' template_show ' = > $v [' template_show '], ' create_time ' + $v [' create_time '], ' str_repeat ' + $str _repeat, ' page_size ' + = $v ['            Page_size ']);            $temparray = Self::get ($v [' id '], $array, ($level + $add));            if ($temparray) {$newarray = Array_merge ($newarray, $temparray); }}} return $newarray;}

The above code in the catalog model, do not understand the wrong should be recursive to get the sub-column such
Now I call the goods

Catalog::get($catalogArr['id'],$catalogArr,2,2,'>>')

Returnarray(0) { }

$catalogArr`打印出来的内容`array(22) { ["id"]=> string(2) "11" ["catalog_name"]=> string(12) "工作动态" ["catalog_name_alias"]=> string(4) "gzdt" ["parent_id"]=> string(1) "0" ["level"]=> int(0) ["sort_order"]=> string(1) "1" ["seo_keywords"]=> string(12) "工作动态" ["seo_description"]=> string(12) "工作动态" ["attach_file"]=> string(0) "" ["attach_thumb"]=> string(0) "" ["status_is"]=> string(1) "Y" ["data_count"]=> string(1) "0" ["display_type"]=> string(4) "list" ["menu_is"]=> string(1) "N" ["template_list"]=> string(9) "list_text" ["acl_browser"]=> string(0) "" ["acl_operate"]=> string(0) "" ["template_page"]=> string(9) "list_page" ["template_show"]=> string(9) "show_post" ["create_time"]=> string(10) "1409390084" ["str_repeat"]=> string(0) "" ["page_size"]=> string(2) "10" }

Ask me to call it that right? " Why can't I get a sub-column?

Paste one of My code:
