脚本宝典收集整理的这篇文章主要介绍了php – 将数组转换为Ul-Li，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
Array
(
[0] => Array
(
[name] => Region
[id] => 3
[parent_id] => 2
[children] => Array
(
[0] => Array
(
[name] => Asia
[id] => 4
[parent_id] => 3
[children] => Array
(
[0] => Array
(
[name] => Central Asia
[id] => 6621
[parent_id] => 4
[children] => Array
(
[0] => Array
(
[name] => Afghanistan
[id] => 5
[parent_id] => 6621
[children] => Array
(
[0] => Array
(
[name] => Balkh
[id] => 6
[parent_id] => 5
[children] => Array
(
[0] => Array
(
[name] => Mazar-e-sharif
[id] => 7
[parent_id] => 6
)
)
)
[1] => Array
(
[name] => Kabol
[id] => 10
[parent_id] => 5
)
[2] => Array
(
[name] => Qandahar
[id] => 12
[parent_id] => 5
)
)
)
)
)
[1] => Array
(
[name] => Middle East
[id] => 6625
[parent_id] => 4
[children] => Array
(
[0] => Array
(
[name] => Armenia
[id] => 14
[parent_id] => 6625
)
)
)
)
)
)
)
)
现在我想将这个数组转换为树形结构中的ul-li
但它给了我奇怪的输出
例如Region我想这样
<li id=3 parent_id=2 > Region </li>
function olLITree($tree) { echo '<ul>'; foreach($tree as $key => $item) { if (is_array($item)) { echo '<li>',$key; olLiTree($item); echo '</li>'; } else { echo '<li>',$item,'</li>'; } } echo '</ul>'; }
<ul>
<li>0
<ul>
<li>Region</li>
<li>3</li>
<li>2</li>
<li>children
<ul>
function olLiTree( $tree ) {
echo '<ul>';
foreach ( $tree as $item ) {
echo "<li id=\"$item[id]\" parent_id=\"$item[parent_id]\" > $item[name] </li>";
if ( isset( $item['children'] ) ) {
olLiTree( $item['children'] );
}
}
echo '</ul>';
}
