PHP无限分类 不知道问题出现在那里了

PHP code

     function catatree($parentid=0){
global $r;
echo '<ul>';
foreach($r AS $key=>$value){
if($parentid == $value["parentid"]){
?>
    <li><div class="ul_info"><?php echo $value['pagename'];?></div>
        <?php if($value["subcatas"]>0){
 catatree($value['id']);
}?>
      </li>
    <?php
}
}
unset($parentid);
echo '</ul>';
unset($value);
}

其实在二级分类里面是有产品1-2的。不知道哪里出错了 没有显示 直接查找自己的子类 然后就没有了

如果不大的话把$r一并打印出来吧

我猜吧，这个程序只处理数组中键值为1的值，没看到你有对id ++方面的处理
因此一直是
$value[1]
$value[1][1]
$value[1][1][1]
直到底层

你数据源估计有问题
