从其他阵列获取组合

Question

I have two array

First

array(
0 => 100000,
1 => 50000,
2 => 100000,
3 => 100000);

Second

array(
0 => 150000,
1 => 200000,);

The problem is I want to get the combination from first array that formed each second array.

Example Second array index 0 can be formed from first array index 0 and 1 and second array index 1 can be formed from first array index 2 and 3

I want to achieve like this

[0 => [0,1] , 1 => [2,3]]

Thanks for the help.

Try with following code:

$arr = array(
0 => 100000,
1 => 50000,
2 => 100000,
3 => 100000);
$count = $val = 0;
$newArr = [];
foreach($arr as $a){
   $val += $a;
   $count++;
   if($count == 2){
     $newArr[] = $val;
     $val = $count = 0; 
   }
}
print_r($newArr); die;
