I have make many changes but still cannot figure out. i have an array let say: [1,2,3,4,5,6,7,8,9,10] i just want to ask how to add this array until index 2 and continued add for rest array then divide them by 2 array each.
input : [1,2,3,4,5,6,7,8,9,10 ];
process : [1+2+3, 4+5+6, 7+8+9, 10]
output i need : [6,15,24,10]
then i want to cut this array into 2
last output : [[6,5],[24,10]]
Thanks
Your code will be:
$data = range(1,10);
$result = array_chunk(array_map('array_sum', array_chunk($data, 3)), 2);
-please, read array functions manual
Something like this?
<?php
$array = range(1, 10);
$array = array_chunk($array, 3);
$array = array_map('array_sum', $array);
$array = array_chunk($array, 2);
print_r(
$array
);
/*
Array
(
[0] => Array
(
[0] => 6
[1] => 15
)
[1] => Array
(
[0] => 24
[1] => 10
)
)
*/
I think you can use a for cycle to sum what you need then store result in new array. Another solution is using array merge. When you've done the trick you can create a multidimensional array to get the result like [[6,5],[24,10]].
Hope it helps
Can't really see what you are getting at from the question, but I think PHP's array_chunk command may be your friend on this, http://www.php.net/manual/en/function.array-chunk.php
this will allow you to split the array into chunks of 3 (or any number) of elements with last element containing the remainder (in this case 1 element)
