本文实例讲述了php通过分类列表产生分类树数组的方法。分享给大家供大家参考。具体分析如下:

这里$list 为分类列表数组,键为分类 ID,值为分类节点对象,pid 为父分类 ID

php代码如下:

$tree = array();
foreach ($list as $id => $row) {
 $pid = $row->pid;
 if ($pid == 0) {
  $tree[] = &$list[$id];
 } else if (isset($list[$pid])) {
  $parent = &$list[$pid];
  $parent->children[] = &$list[$id];
  // 增加 children 属性标识子分类列表
 }
}
Copy after login

希望本文所述对大家的php程序设计有所帮助。
