但是要怎样遍历这个方法产生的二叉树数组呢？以下是我的做法：

复制代码 代码如下:

<?php

function preTree($cat){

foreach ($cat as $c){

?>

<p><a href="http://<?=$c['poper_site']?>"><?=$c['poper']?></a>:<?=t($c['content'])?></p>

<?php if(isset($c['childrens'])){?>

<ul>

<?php foreach ($c['childrens'] as $s){?>

<li><p><a href="http://<?=$s['poper_site']?>"><?=$s['poper']?></a>:<?=t($s['content'])?></p>

<?php

if(isset($s['childrens'])){

?><ul><li><?php

$this->preTree($s['childrens']);

?></li></ul><?php

}

?>

</li>

<?php }?>

</ul>

<?php }?>

<?php

}

}

?>
