Write a program to read an array of integers and condense them by summing adjacent couples of elements until a single integer is obtained. For example, if we have 3 elements {2, 10, 3}, we sum the first two and the second two elements and obtain {2+10, 10+3} = {12, 13}, then we sum again all adjacent elements and obtain {12+13} = {25}.

My solution to your task:
<?php
$arr = array_map('intval', explode(' ', readline()));
while (count($arr) > 1) {
$arrNew = [];
for ($i = 0; $i < count($arr) - 1; $i++) {
$arrNew[$i] = $arr[$i] + $arr[$i + 1];
}
$arr = $arrNew;
}
echo $arr[0];
