本文实例讲述了php可应用于面包屑导航的递归寻找家谱树实现方法。分享给大家供大家参考。具体实现方法如下:

<&#63;php
echo "<pre class="brush:php;toolbar:false">";
$area = array(
array('id'=>1,'area'=>'北京','pid'=>0),
array('id'=>2,'area'=>'广西','pid'=>0),
array('id'=>3,'area'=>'广东','pid'=>0),
array('id'=>4,'area'=>'福建','pid'=>0),
array('id'=>11,'area'=>'朝阳区','pid'=>1),
array('id'=>12,'area'=>'海淀区','pid'=>1),
array('id'=>21,'area'=>'南宁市','pid'=>2),
array('id'=>45,'area'=>'福州市','pid'=>4),
array('id'=>113,'area'=>'亚运村','pid'=>11),
array('id'=>115,'area'=>'奥运村','pid'=>11),
array('id'=>234,'area'=>'武鸣县','pid'=>21)
); 

function familytree($arr,$id){
 static $list = array();
 foreach($arr as $v){
 if($v['id']==$id){
  familytree($arr,$v['pid']);
  $list[] = $v;
 }
 }
 return $list;
}
print_r(familytree($list,113));
&#63;>

希望本文所述对大家的php程序设计有所帮助。
