请你给出测试数据
http://bbs.csdn.net/topics/390398703 跟这个帖子结合下...
就是个无限分类 他这个无限分类是按table显示的 在td前面加空格 来区分 一级二级栏目的
我想用div 实现
Array
(
[2] => Array
(
[classid] => 6
[classfid] => 0
[classname] => 栏目一
)
[1] => Array
(
[id] => 7
[classfid] => 6
[classname] => 栏目1-1
)
[0] => Array
(
[classid] => 10
[classfid] => 7
[classname] => 栏目1-1-1
)
)
差不多 就这数据
function add_($num){
$str='';
for($i=1;$i<=$num;$i++){
$str.=' ';
}
return $str;
}
function tree($_arr,$i=-1){
$_tree='';
$i++;
foreach ($_arr as $_key => $_value){
if(is_array($_value)){
$_tree.=add_($i).$_key.'
';
$_tree.=tree($_value,$i);
}else{
$_tree.=add_($i).$_key.'=>'.$_value.'
';
}
}
return $_tree;
}
试试这两个函数，再自加点HTML标签。
$ar = array ( 2 => array ( 'classid' => '6', 'classfid' => '0', 'classname' => '栏目一', ), 1 => array ( 'id' => '7', 'classfid' => '6', 'classname' => '栏目1-1', ), 0 => array ( 'classid' => '10', 'classfid' => '7', 'classname' => '栏目1-1-1', ),);echo '<ul>';foreach($ar as $item) { if($item['classfid'] == 0) $deep = 0; $t = substr_count($item['classname'], '-'); if($t < $deep) echo '</li></ul>'; if($t > $deep) echo '<ul>'; echo '<li>'.$item['classname']; $deep = $t;}while($deep--) echo '</li></ul>'; 可能提供的数据不全 不是按照“-”号区分的
