这是我的数组:
$list = array(
array('id' => 3, 'name' => 'Phones', 'parent_id' => 0,),
array('id' => 256, 'name' => 'Accessories', 'parent_id' => 0,),
array('id' => 308, 'name' => 'Appliances', 'parent_id' => 0,),
array('id' => 1057, 'name' => 'Smart', 'parent_id' => 0,),
array('id' => 1065, 'name' => 'Smart Phones', 'parent_id' => 3,),
array('id' => 1066, 'name' => 'Feature Phones', 'parent_id' => 3,),
array('id' => 1069, 'name' => 'Samsung', 'parent_id' => 1065,),
array('id' => 1070, 'name' => 'Apple', 'parent_id' => 1065,),
array('id' => 1072, 'name' => 'Apple', 'parent_id' => 1066,),
array('id' => 1075, 'name' => 'Tablets', 'parent_id' => 0,),
array('id' => 1076, 'name' => 'Samsung', 'parent_id' => 1066,),
array('id' => 1077, 'name' => 'All Brands', 'parent_id' => 1075,),
array('id' => 1078, 'name' => 'Samsung', 'parent_id' => 1077,),
array('id' => 1079, 'name' => 'Protector', 'parent_id' => 256,),
array('id' => 1080, 'name' => 'Power', 'parent_id' => 256,),
array('id' => 1081, 'name' => 'Cable', 'parent_id' => 256,),
array('id' => 1082, 'name' => 'Memory', 'parent_id' => 256,),
);
这是我分类的代码:
function quote_make_tree($list,$deep=1, $root = 0)
{
$tree = $packData = [];
foreach ($list as $row) {
$packData[$row['id']] = $row;
}
foreach ($packData as $key => $val) {
if ($val['parent_id'] == $root) {
$tree[] = &$packData[$key];
} else {
$packData[$val['parent_id']]['children'][] = &$packData[$key];
}
}
return $tree;
}
我想添加一个深度参数$deep来quote_make_tree控制分类的深度。
if $deep = 2,获取level 1分类下的level 2分类,if $deep=3,获取所有1,2,3分类
我已经尝试先获取所有数据,然后根据$deep.here is demo删除数据,谢谢大家
