php如何遍历交叉的多维数组并给其id和pid(父键id)
- PHP code
array(7) { [1] => array(5) { ["id"] => string(1) "1" ["pid"] => string(1) "0" ["name"] => string(15) "AssetManagement" ["title"] => string(12) "资产管理" ["submenu"] => array(1) { [0] => string(0) "" } } [2] => array(5) { ["id"] => string(1) "2" ["pid"] => string(1) "0" ["name"] => string(14) "SystemSettings" ["title"] => string(12) "系统设置" ["submenu"] => array(1) { [0] => string(0) "" } } [3] => array(5) { ["id"] => string(1) "3" ["pid"] => string(1) "0" ["name"] => string(19) "Management" ["title"] => string(12) "后台管理" ["submenu"] => array(1) { [0] => string(0) "" } } [4] => array(5) { ["id"] => string(2) "11" ["pid"] => string(1) "1" ["name"] => string(9) "HZ" ["title"] => string(15) "HZ" ["submenu"] => array(1) { [0] => string(0) "" } } [5] => array(5) { ["id"] => string(2) "10" ["pid"] => string(1) "1" ["name"] => string(9) "XM" ["title"] => string(15) "XM" ["submenu"] => array(1) { [0] => string(0) "" } } [6] => array(5) { ["id"] => string(1) "9" ["pid"] => string(1) "1" ["name"] => string(9) "BJ" ["title"] => string(15) "BJ" ["submenu"] => array(1) { [0] => string(0) "" } } [7] => array(5) { ["id"] => string(1) "4" ["pid"] => string(1) "1" ["name"] => string(20) "TotalManagement" ["title"] => string(15) "总管理" ["submenu"] => array(3) { [0] => array(5) { ["id"] => string(1) "5" ["name"] => string(12) "PC" ["menu_id"] => string(1) "4" ["title"] => string(17) "PC" ["access"] => int(1) } [1] => array(5) { ["id"] => string(1) "6" ["name"] => string(13) "BJB" ["menu_id"] => string(1) "4" ["title"] => string(18) "BJB" ["access"] => int(1) } [2] => array(5) { ["id"] => string(1) "7" ["name"] => string(16) "Select" ["menu_id"] => string(1) "4" ["title"] => string(15) "查询" ["access"] => int(1) } } } } 怎么把上面的数组写成下面那样? array(3) { [1] => array(5) { ["id"] => string(1) "1" ["pid"] => string(1) "0" ["name"] => string(15) "AssetManagement" ["title"] => string(12) "资产管理" ["submenu"] => array(4) { [1] => array(5) { ["id"] => string(2) "11" ["pid"] => string(1) "1" ["name"] => string(9) "HZ" ["title"] => string(15) "HZ" ["submenu"] => array(1) { [0] => string(0) "" } } [2] => array(5) { ["id"] => string(2) "10" ["pid"] => string(1) "1" ["name"] => string(9) "XM" ["title"] => string(15) "XM" ["submenu"] => array(1) { [0] => string(0) "" } } [3] => array(5) { ["id"] => string(1) "9" ["pid"] => string(1) "1" ["name"] => string(9) "BJ" ["title"] => string(15) "BJ" ["submenu"] => array(1) { [0] => string(0) "" } } [4] => array(5) { ["id"] => string(1) "4" ["pid"] => string(1) "1" ["name"] => string(20) "TotalManagement" ["title"] => string(15) "总管理" ["submenu"] => array(3) { [0] => array(5) { ["id"] => string(1) "5" ["name"] => string(12) "PC" ["menu_id"] => string(1) "4" ["title"] => string(17) "PC" ["access"] => int(1) } [1] => array(5) { ["id"] => string(1) "6" ["name"] => string(13) "BJB" ["menu_id"] => string(1) "4" ["title"] => string(18) "BJB" ["access"] => int(1) } [2] => array(5) { ["id"] => string(1) "7" ["name"] => string(16) "Select" ["menu_id"] => string(1) "4" ["title"] => string(15) "查询" ["access"] => int(1) } } } } } [2] => array(5) { ["id"] => string(1) "2" ["pid"] => string(1) "0" ["name"] => string(14) "SystemSettings" ["title"] => string(12) "系统设置" ["submenu"] => array(1) { [0] => string(0) "" } } [3] => array(5) { ["id"] => string(1) "3" ["pid"] => string(1) "0" ["name"] => string(19) "Management" ["title"] => string(12) "后台管理" ["submenu"] => array(1) { [0] => string(0) "" } } }
