本文实例讲述了php简单实现无限分类树形列表的方法。分享给大家供大家参考。具体如下:
- $items = array(
- 1 => array('id' => 1, 'pid' => 0, 'name' => '江西省'),
- 2 => array('id' => 2, 'pid' => 0, 'name' => '黑龙江省'),
- 3 => array('id' => 3, 'pid' => 1, 'name' => '南昌市'),
- 4 => array('id' => 4, 'pid' => 2, 'name' => '哈尔滨市'),
- 5 => array('id' => 5, 'pid' => 2, 'name' => '鸡西市'),
- 6 => array('id' => 6, 'pid' => 4, 'name' => '香坊区'),
- 7 => array('id' => 7, 'pid' => 4, 'name' => '南岗区'),
- 8 => array('id' => 8, 'pid' => 6, 'name' => '和兴路'),
- 9 => array('id' => 9, 'pid' => 7, 'name' => '西大直街'),
- 10 => array('id' => 10, 'pid' => 8, 'name' => '东北林业大学'),
- 11 => array('id' => 11, 'pid' => 9, 'name' => '哈尔滨工业大学'),
- 12 => array('id' => 12, 'pid' => 8, 'name' => '哈尔滨师范大学'),
- 13 => array('id' => 13, 'pid' => 1, 'name' => '赣州市'),
- 14 => array('id' => 14, 'pid' => 13, 'name' => '赣县'),
- 15 => array('id' => 15, 'pid' => 13, 'name' => '于都县'),
- 16 => array('id' => 16, 'pid' => 14, 'name' => '茅店镇'),
- 17 => array('id' => 17, 'pid' => 14, 'name' => '大田乡'),
- 18 => array('id' => 18, 'pid' => 16, 'name' => '义源村'),
- 19 => array('id' => 19, 'pid' => 16, 'name' => '上坝村'),
- 20 => array('id' => 20, 'pid' => 0, 'name' => '广东省'),
- 21 => array('id' => 21, 'pid' => 20, 'name' => '广州市'),
- );
- $t = array();
- foreach ($items as $id => $item) {
- if ($item['pid']) {
- $items[$item['pid']][$item['id']] = &$items[$item['id']];
- $t[] = $id;
- }
- }
- foreach($t as $u) {
- unset($items[$u]);
- }
- echo "<pre>";
- print_r($items);
希望本文所述对大家的php程序设计有所帮助。
