Create an array from two array PHP - php

Question

i have two arrays
$value_array = array('50','40','30','20','10');
$customer = array('300','200','100');
i want to distribute the value array to customers based on the value of customers that is taken as limit.adding values by checking it wont cross the limit that is 300 , 200 and 100.
but customer array not working one direction it should work first forward and then backward like that
i want to produce an array in form of
Array
(
[0] => Array
(
[0] => 50
)
[1] => Array
(
[0] => 40
[1] => 10
)
[2] => Array
(
[0] => 30
[1] => 20
)
)
After completing customer loop first time it should start from last to first. both array count will change , i mean count.
value array should check 50 -> 300 , 40->200, 30->100 then from last ie, 20 ->100, 10->200 etc.
I tried like
$i = 0;
while($i < count($customer)){
foreach($value_array as $k=>$value){
$v = 0;
if($value <= $customer[$i]){
$customer2[$i][] = $value;
unset($value_array[$k]);
$v = 1;
}
if($v ==1){
break;
}
}
//echo $i."<br/>";
if($i == (count($customer)-1) && (!empty($value_array))){
$i = 0;
$customer = array_reverse($customer, true);
}
$i++;
}
echo "<pre>";
print_r($customer2);

$valueArray = array('50','40','30','20','10','0','-11');
$customer = array('300','200','100');
function parse(array $valueArr, array $customerArr)
{
$customerCount = count($customerArr);
$chunkedValueArr = array_chunk($valueArr, $customerCount);
$temp = array_fill(0, $customerCount, array());
$i = 0;
foreach ($chunkedValueArr as $item) {
foreach ($item as $key => $value) {
$temp[$key][] = $value;
}
$temp = rotateArray($temp);
$i++;
}
// if $i is odd
if ($i & 1) {
$temp = rotateArray($temp);
}
return $temp;
}
function rotateArray(array $arr)
{
$rotatedArr = array();
//set the pointer to the last element and add it to the second array
array_push($rotatedArr, end($arr));
//while we have items, get the previous item and add it to the second array
for($i=0; $i<sizeof($arr)-1; $i++){
array_push($rotatedArr, prev($arr));
}
return $rotatedArr;
}
print_r(parse($valueArray, $customer));
returns:
Array
(
[0] => Array
(
[0] => 50
[1] => 0
[2] => -11
)
[1] => Array
(
[0] => 40
[1] => 10
)
[2] => Array
(
[0] => 30
[1] => 20
)
)
