Sum of value based on the key PHP - php

Question

We have and array like below in PHP, and want to create a new array in the new array there should be the unique key and the value from the same key should be added.
Array
(
[0] => Array
(
[58] => 32.00
)
)
Array
(
[0] => Array
(
[58] => 34.00
)
)
Array
(
[0] => Array
(
[57] => 26.00
)
)
Array
(
[0] => Array
(
[57] => 27.00
)
)
Array
(
[0] => Array
(
[56] => 16.00
)
)
Array
(
[0] => Array
(
[56] => 17.00
)
)
We want to create new array with the help of the above array.
The value of same key should be added.
The output of new array should be like below.
Array
(
[58] => 66
[57] => 53
[56] => 33
)
code is below
The output of minmaxarray is
Array
(
[0] => Array
(
[min] => 35.00
[max] => 50.00
[price] => 26.00
)
[1] => Array
(
[min] => 50.00
[max] => 80.00
[price] => 29.00
)
[2] => Array
(
[min] => 80.00
[max] => 100.00
[price] => 32.00
)
[3] => Array
(
[min] => 100.00
[max] => 150.00
[price] => 34.00
)
[4] => Array
(
[min] => 150.00
[max] => 180.99
[price] => 36.00
)
)
$shippingPrice = array();
foreach ($minmaxarray as $key => $value) {
if($price > $value['min'] && $price < $value['max'])
{
if($value['price'])
{
$shippingPrice[][$smethodid] = $value['price'];
break;
}
}
}
echo '<pre>'; print_r ($shippingPrice);
Thanks

Answer 1

If your array structure is always the same like you have posted, then this code will work for you:
$example_array = array(
array( '0' => 32.00 ),
array( '2' => 32.00 ),
array( '2' => 32.00 )
);
$new_array = array();
// loop through every item in nested foreach
foreach( $example_array as $value ) {
foreach( $value as $key => $number ) {
// if the array key not exist, calculate with 0, otherwise calculate with the actual value
$new_array[$key] = isset($new_array[$key]) ? $new_array[$key] + $number : 0 + $number;
}
}
print_r( $new_array );
// prints Array ( [0] => 32 [2] => 64 )
Code example for your arrays:
$shippingPrice = array();
// loop through every item in nested foreach
foreach( $minmaxarray as $value ) {
foreach( $value as $key => $number ) {
// if the array key not exist, calculate with 0, otherwise calculate with the actual value
$shippingPrice[$key] = isset($shippingPrice[$key]) ? $shippingPrice[$key] + $number : 0 + $number;
}
}
echo '<pre>';
print_r( $shippingPrice );

Answer 2

You can try this code
function array_flatten($array) {
if (!is_array($array)) {
return FALSE;
}
$result = array();
foreach($array as $key=> $value){
if (is_array($value)) {
$result = array_merge($result, array_flatten($value));
}
else {
$result[$key] = $value;
}
}
return $result;
}
You call this function by your array then function will return your expected array.
array_flatten($array);

Answer 3

You can use array_walk_recursive instead of 2 foreach loop
array_walk_recursive($arr, function($v,$k) use (&$r){
$r[$k] = isset($r[$k]) ? ($r[$k]+$v) : $v;
});
