更新 var_export数组版本HERE
我有以下数组，我想根据UNILEVEL值对元素/子元素进行分组：
array(
0 => array(
"member_id" => 3,
"unilevel" => 1,
"children" => array(
0 => array(
"member_id" => 4,
"unilevel" => 2,
"children" => array(
0 => array(
"member_id" => 6,
"unilevel" => 3,
"children" => array(
0 => array(
"member_id" => 7,
"unilevel" => 4 ) ) ) ) )
1 => array(
"member_id" => 9
"unilevel" => 2 ) ) )
1 => array(
"member_id" => 5,
"unilevel" => 1,
"children" => array(
0 => array(
"member_id" => 8,
"unilevel" => 2,
"children" => array(
0 => array(
"member_id" => 10,
"unilevel" => 3 ) ) ) ) ) )
下面的Controller有一个名为groupPerlevel的函数进行分组，但它现在只对第一个父组合，它已经是一个递归函数，我不知道它为什么不把第二个父元素放在上面不完美的分组。
class TestController extends Controller {
private $group = array();
private function setGroup($value) {
$this->group = $this->group + $value;
}
private function getGroup() {
return $this->group;
}
public function create()
{
$this->groupPerlevel($tree);
dd($this->getGroup());
}
private function groupPerlevel(array $items)
{
var_dump($items);
$grouparr = $this->getGroup();
$newkey = 0;
$templevel = 1;
foreach($items as $key => $val) {
if($templevel == $val->unilevel) {
$grouparr[$templevel][$newkey] = $val;
$this->setGroup($grouparr);
} else {
if(isset($grouparr[$val->unilevel][$newkey])) {
$count = count($grouparr[$val->unilevel]);
$grouparr[$val->unilevel][$count] = $val;
$this->setGroup($grouparr);
} else {
$grouparr[$val->unilevel][$newkey] = $val;
}
}
if(isset($val->children)) {
$children = $val->children;
unset($val->children);
$this->groupPerlevel($children);
}
$newkey++;
}
$this->setGroup($grouparr);
}
}
以下数组将是我想要的输出。 array（4）{ [1] 是UNILEVEL（组），因此所有元素/子元素都应根据其unilevel字段值位于其正确的unilevel组中。但它只对第一个父母进行，第二个父母不进行分组。
array(
1 => array(
0 => array(
"member_id" => 3,
"unilevel" => 1 ) )
4 => array(
0 => array(
"member_id" => 7,
"unilevel" => 4 ) )
3 => array(
0 => array (
"member_id" => 6,
"unilevel" => 3 ) )
2 => array(
0 => array(
"member_id" => 4,
"unilevel" => 2
1 => array(
"member_id" => 9
"unilevel" => 2 )))
答案 0 :(得分：0)
对不起，迟到的回复试试这个
$arr=array("shiva" => array("member_id" => "3","unilevel" => "1","children" => array("0" => array("member_id" => "4","unilevel" => "2","children" => array("0" => array("member_id" => "6", "unilevel" => "3", "children" => array( "0" => array( "member_id" => "7", "unilevel" => "4" ) ) ) ) ), "1" => array( "member_id" => "9", "unilevel" => "2" ))),"1" => array("member_id" => "5","unilevel" => "1","children" => array("0" => array("member_id" => "8","unilevel" => "2", "children" => array( "0" => array( "member_id" => "10", "unilevel" => "3" ) ) ) ) ) );
function check($arr){
if(is_array($arr)){
foreach($arr as $arr1){
foreach($arr1 as $arr2){
if(is_array($arr2)){
return true;
}
}
}
}
else{
return false;
}
return false;
}
$i=0;
while(check($arr)){
foreach($arr as $arr1key=>$arr1val){
foreach($arr1val as $arr2key=>$arr2val){
if(is_array($arr2val)){
$arr[]=$arr[$arr1key][$arr2key];
unset($arr[$arr1key][$arr2key]);
}
}
}
}
foreach($arr as $arr1key=>$arr1val)
{
if(count($arr1val)==0){
unset($arr[$arr1key]);
}
}
//print_r($arr);
$result=array();
$values=array();
foreach($arr as $arr1key=>$arr1val)
{
if(((array_key_exists("unilevel", $arr1val)) || (array_key_exists("member_id", $arr1val)))==true)
{
$key=$arr1val['unilevel'];
$result[0][$key][]=array("unilevel"=>$arr1val["unilevel"],"member_id"=>$arr1val["member_id"]);
}
}
print_r($result);
结果：
数组（[0] =＆gt;数组（[1] =＆gt;数组（[0] =＆gt;数组（[unilevel] =＆gt; 1 [member_id] =＆gt; 3）[1] =＆gt;数组（[unilevel] =＆gt; 1 [member_id] =＆gt; 5））[2] =＆gt;数组（[0] =＆gt;数组（[unilevel] =＆gt; 2 [member_id] =＆gt; 4）[ 1] =＆gt;数组（[unilevel] =＆gt; 2 [member_id] =＆gt; 9）[2] =＆gt;数组（[unilevel] =＆gt; 2 [member_id] =＆gt; 8））[3] = ＆gt;数组（[0] =＆gt;数组（[unilevel] =＆gt; 3 [member_id] =＆gt; 6）[1] =＆gt;数组（[unilevel] =＆gt; 3 [member_id] =＆gt; 10） ）[4] =＆gt;数组（[0] =＆gt;数组（[unilevel] =＆gt; 4 [member_id] =＆gt; 7））））
