PHP实现处理三级分类数据的示例代码
作者：荣~博客
这篇文章主要为大家详细介绍了如何利用PHP实现处理三级分类数据,文中的示例代码讲解详细,具有一定的借鉴价值,有需要的小伙伴可以参考一下
一、原始数据
function getDatas(){
return [
[
'component' => 'system',
'redict' => '/system',
'path' => '/system',
'hidden' => 1,
'name' => '系统管理',
'children' => [
[
'component' => 'user',
'redict' => '/user',
'path' => '/user',
'hidden' => 1,
'name' => '用户管理',
'children' => [
[
'component' => 'user_list',
'redict' => '/user_list',
'path' => '/user_list',
'hidden' => 1,
'name' => '用户列表',
],
[
'component' => 'role',
'redict' => '/user_role',
'path' => '/user_role',
'hidden' => 1,
'name' => '角色列表',
],
[
'component' => 'perm',
'redict' => '/perm',
'path' => '/perm',
'hidden' => 1,
'name' => '权限列表',
],
]
],
[
'component' => 'data',
'redict' => '/data',
'path' => '/data',
'hidden' => 1,
'name' => '数据管理',
'children' => [
[
'component' => 'report',
'redict' => '/report',
'path' => '/report',
'hidden' => 1,
'name' => '分日报表',
],
[
'component' => 'hour_report',
'redict' => '/hour_report',
'path' => '/hour_report',
'hidden' => 1,
'name' => '分时报表',
],
[
'component' => 'month_report',
'redict' => '/month_report',
'path' => '/month_report',
'hidden' => 1,
'name' => '分月报表',
],
]
],
[
'component' => 'resource',
'redict' => '/resource',
'path' => '/resource',
'hidden' => 1,
'name' => '资源管理',
'children' => [
[
'component' => 'res_list',
'redict' => '/res_list',
'path' => '/res_list',
'hidden' => 1,
'name' => '资源列表'
]
]
]
]
]
]
}
二、函数处理
function deal(){
$datas = getDatas();
$level_1_tree = [];
foreach($datas as $data_level_1){
$data_level_1_arr['component'] = $data_level_1['component'];
$data_level_1_arr['redict'] = $data_level_1['redict'];
$data_level_1_arr['path'] = $data_level_1['path'];
$data_level_1_arr['meta'] = [
'title' => $data_level_1['name'],
'hidden' => $data_level_1['hidden']
];
$level_2_tree = [];
if(isset($data_level_1['children']) && !empty($data_level_1['children'])) {
foreach ($data_level_1['children'] as $data_level_2) {
$data_level_2_arr['component'] = $data_level_2['component'];
$data_level_2_arr['redict'] = $data_level_2['redict'];
$data_level_2_arr['path'] = $data_level_2['path'];
$data_level_2_arr['meta'] = [
'title' => $data_level_2['name'],
'hidden' => $data_level_2['hidden']
];
$level_3_tree = [];
if (isset($data_level_2['children']) && !empty($data_level_2['children'])) {
foreach ($data_level_2['children'] as $data_level_3) {
$data_level_3_arr['component'] = $data_level_3['component'];
$data_level_3_arr['redict'] = $data_level_3['redict'];
$data_level_3_arr['path'] = $data_level_3['path'];
$data_level_3_arr['meta'] = [
'title' => $data_level_3['name'],
'hidden' => $data_level_3['hidden']
];
array_push($level_3_tree, $data_level_3_arr);
unset($data_level_3_arr);
}
$data_level_2_arr['children'] = $level_3_tree;
}
array_push($level_2_tree, $data_level_2_arr);
unset($data_level_2_arr);
}
$data_level_1_arr['children'] = $level_2_tree;
}
array_push($level_1_tree, $data_level_1_arr);
unset($data_level_1_arr);
}
print_r($level_1_tree);
}
deal();三、方法补充
除了上文的方法，小编还为大家整理了PHP处理三级分类数据的其他方法，希望对大家有所帮助
示例代码
<?php
//瞎写的
// 链接数据库
$link = mysqli_connect('localhost','root','root');
if($link == null){
exit;
}
mysqli_select_db($link,'test');
$link->query("SET NAMES utf8");
$sql = "select * from tp_goods_categorys";
$res = mysqli_query($link,$sql);
while($res && $row = mysqli_fetch_assoc($res)) {
$list[] = $row;
}
echo '<pre>';
print_r(res($list));
function res($items){
$tree = array();
foreach($items as $key =>$val){
$list = explode(',',$val['categorys_path']);
switch(count($list)){
case 1:
$tree[$val['id']] = $val;
break;
case 2:
$tree[$val['categorys_pid']]['son'][$val['id']] = $val;
break;
case 3:
$tree[$list[1]]['son'][$list[2]]['son'] = $val;
break;
}
}
return $tree;
}<?php
//递归
$array = array(
array('id' => 1, 'pid' => 0, 'name' => '湖北省'),
array('id' => 2, 'pid' => 0, 'name' => '北京市'),
array('id' => 3, 'pid' => 1, 'name' => '武汉市'),
array('id' => 4, 'pid' => 2, 'name' => '朝阳区'),
array('id' => 5, 'pid' => 2, 'name' => '通州区'),
array('id' => 6, 'pid' => 4, 'name' => '望京'),
array('id' => 7, 'pid' => 4, 'name' => '酒仙桥'),
array('id' => 8, 'pid' => 3, 'name' => '武昌区'),
array('id' => 9, 'pid' => 1, 'name' => '武安市'),
);
function cation($arr,$num=0,$m=1)
{
$list = [];
foreach($arr as $k=>$v){
if($v['pid'] === $num){
$v['level'] = $m;
$v['son'] = cation($arr,$v['id'],$m+1);
$list[] = $v;
}
}
return $list;
}
$list = cation($array);
echo '<pre>';
print_r($list);
echo '</pre>';另一种需求
（重组一维数组）
// 处理分类数据 栏目分级
public function allMenu($cates,$pid=0,$level=0){
static $cateArr = array();
for($i=0;$i<count($cates);$i++){
if($cates[$i]['pid']==$pid){
$cates[$i]['level']=$level;
$cateArr[]=$cates[$i];
$this->allMenu($cates,$cates[$i]['id'],$level+1);
}
}
return $cateArr;
