两个循环的事，何必来问
源数据不好，应该order by pid, id，这样会产生类似以下数据：
<code>$data = array(
array('id' => 1, 'pid' => 0),
array('id' => 2, 'pid' => 0),
array('id' => 3, 'pid' => 1),
array('id' => 4, 'pid' => 1),
array('id' => 5, 'pid' => 3),
);</code>
然后通过一次for循环将下标设为id值（有的框架搜索结果已经用了这种形式的可以省略这一步）
<code>$tree = [];
foreach ($data as $row) {
$tree[$row['id']] = $row;
}</code>
然后构造树形结构
<code>foreach ($tree as $id => $row) {
if (! isset($row['_childs'])) $tree[$id]['_childs'] = [];
if (! empty($row['pid'])) {
$tree[$row['pid']]['_childs'][] = &$tree[$id];
}
}
//现在包含了冗余数据
print_r($tree);</code>
可以去掉冗余部分，也可以留着
<code>foreach ($tree as $id => $row) {
if (! empty($row['pid'])) unset($tree[$id]);
}
print_r($tree);</code>
