本文實例講述了php簡單實現(xiàn)無限分類樹形列表的方法。分享給大家供大家參考。具體如下：

$items = array(

1 => array('id' => 1, 'pid' => 0, 'name' => '江西省'),

2 => array('id' => 2, 'pid' => 0, 'name' => '黑龍江省'),

3 => array('id' => 3, 'pid' => 1, 'name' => '南昌市'),

4 => array('id' => 4, 'pid' => 2, 'name' => '哈爾濱市'),

5 => array('id' => 5, 'pid' => 2, 'name' => '雞西市'),

6 => array('id' => 6, 'pid' => 4, 'name' => '香坊區(qū)'),

7 => array('id' => 7, 'pid' => 4, 'name' => '南崗區(qū)'),

8 => array('id' => 8, 'pid' => 6, 'name' => '和興路'),

9 => array('id' => 9, 'pid' => 7, 'name' => '西大直街'),

10 => array('id' => 10, 'pid' => 8, 'name' => '東北林業(yè)大學'),

11 => array('id' => 11, 'pid' => 9, 'name' => '哈爾濱工業(yè)大學'),

12 => array('id' => 12, 'pid' => 8, 'name' => '哈爾濱師范大學'),

13 => array('id' => 13, 'pid' => 1, 'name' => '贛州市'),

14 => array('id' => 14, 'pid' => 13, 'name' => '贛縣'),

15 => array('id' => 15, 'pid' => 13, 'name' => '于都縣'),

16 => array('id' => 16, 'pid' => 14, 'name' => '茅店鎮(zhèn)'),

17 => array('id' => 17, 'pid' => 14, 'name' => '大田鄉(xiāng)'),

18 => array('id' => 18, 'pid' => 16, 'name' => '義源村'),

19 => array('id' => 19, 'pid' => 16, 'name' => '上壩村'),

20 => array('id' => 20, 'pid' => 0, 'name' => '廣東省'),

21 => array('id' => 21, 'pid' => 20, 'name' => '廣州市'),

);

$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);

希望本文所述對大家的php程序設計有所幫助。
