| 代码如下 | |
| $items = array( array('id' => 1, 'pid' => 0, 'name' => '一级11' ), array('id' => 11, 'pid' => 0, 'name' => 'www.111cn.net 一级12' ), array('id' => 2, 'pid' => 1, 'name' => '二级21' ), array('id' => 10, 'pid' => 11, 'name' => '二级22' ), array('id' => 3, 'pid' => 1, 'name' => '二级23' ), array('id' => 12, 'pid' => 11, 'name' => '二级24' ), array('id' => 13, 'pid' => 12, 'name' => '三级31' ), array('id' => 9, 'pid' => 1, 'name' => '二级25' ), ); |
函数：
| 代码如下 | |
| function formatTree($array, $pid = 0){ $arr = array(); $tem = array(); foreach ($array as $v) { if ($v['pid'] == $pid) { $tem = formatTree($array, $v['id']); //判断是否存在子数组 $tem && $v['son'] = $tem; $arr[] = $v; } } return $arr; } |
其中，数组一定要包含id和pid用以指定数组值之间的层级关系
