php多级树形菜单代码

树形菜单是很多应用中会碰到的一个算法，下文小编就为大家介绍php树形菜单实现方法。

<script>ec(2);</script>

数据库结果

 

打印如下：

代码如下

复制代码

array(7) {   [0] => array(5) {     ["id"] => string(1) "4"     ["fzname"] => string(12) "山猫小号"     ["userid"] => string(2) "12"     ["pid"] => string(1) "0"     ["time"] => string(10) "1413359977"   }   [1] => array(5) {     ["id"] => string(1) "5"     ["fzname"] => string(12) "山猫一组"     ["userid"] => string(2) "12"     ["pid"] => string(1) "4"     ["time"] => string(10) "1413361206"   }   [2] => array(5) {     ["id"] => string(1) "6"     ["fzname"] => string(12) "山猫二组"     ["userid"] => string(2) "12"     ["pid"] => string(1) "4"     ["time"] => string(10) "1413361225"   }   [3] => array(5) {     ["id"] => string(1) "7"     ["fzname"] => string(15) "山猫一组子"     ["userid"] => string(2) "12"     ["pid"] => string(1) "5"     ["time"] => string(10) "1413361388"   }   [4] => array(5) {     ["id"] => string(1) "8"     ["fzname"] => string(15) "山猫一组子"     ["userid"] => string(2) "12"     ["pid"] => string(1) "5"     ["time"] => string(10) "1413361409"   }   [5] => array(5) {     ["id"] => string(1) "9"     ["fzname"] => string(16) "山猫一组子3"     ["userid"] => string(2) "12"     ["pid"] => string(1) "5"     ["time"] => string(10) "1413361460"   }   [6] => array(5) {     ["id"] => string(2) "10"     ["fzname"] => string(15) "山猫二组子"     ["userid"] => string(2) "12"     ["pid"] => string(1) "6"     ["time"] => string(10) "1413361506"   } }

结果：

 

 打印如下：

代码如下

复制代码

array(1) {   [0] => array(5) {     ["id"] => string(1) "4"     ["fzname"] => string(12) "山猫小号"     ["userid"] => string(2) "12"     ["pid"] => array(2) {       [0] => array(5) {         ["id"] => string(1) "5"         ["fzname"] => string(12) "山猫一组"         ["userid"] => string(2) "12"         ["pid"] => array(3) {           [0] => array(5) {             ["id"] => string(1) "7"             ["fzname"] => string(15) "山猫一组子"             ["userid"] => string(2) "12"             ["pid"] => string(0) ""             ["time"] => string(10) "1413361388"           }           [1] => array(5) {             ["id"] => string(1) "8"             ["fzname"] => string(15) "山猫一组子"             ["userid"] => string(2) "12"             ["pid"] => string(0) ""             ["time"] => string(10) "1413361409"           }           [2] => array(5) {             ["id"] => string(1) "9"             ["fzname"] => string(16) "山猫一组子3"             ["userid"] => string(2) "12"             ["pid"] => string(0) ""             ["time"] => string(10) "1413361460"           }         }         ["time"] => string(10) "1413361206"       }       [1] => array(5) {         ["id"] => string(1) "6"         ["fzname"] => string(12) "山猫二组"         ["userid"] => string(2) "12"         ["pid"] => array(1) {           [0] => array(5) {             ["id"] => string(2) "10"             ["fzname"] => string(15) "山猫二组子"             ["userid"] => string(2) "12"             ["pid"] => string(0) ""             ["time"] => string(10) "1413361506"           }         }         ["time"] => string(10) "1413361225"       }     }     ["time"] => string(10) "1413359977"   } }

工用到两个函数1生成树形代码：

代码如下	复制代码
function getTree($data, $pId) { $tree = ''; foreach($data as $k => $v) {    if($v['pid'] == $pId)    {     $v['pid'] = $this->getTree($data, $v['id']);     $tree[] = $v;     //unset($data[$k]);    } } return $tree; }

函数2转化为html代码：

代码如下	复制代码
function procHtml($tree) { $html = ''; foreach($tree as $t) {    if($t['pid'] == '')    {     $html .= " {$t['fzname']} ";    }    else    {     $html .= " ".$t['fzname'];     $html .= $this->procHtml($t['pid']);     $html = $html." ";    } } return $html ? ' '.$html.' ' : $html ; }
