Sum up the array values - php

Question

Array
(
[0] => Array( [0] => Array( [value] => 25 ) )
[1] => Array( [0] => Array( [value] => 75 ) )
[2] => Array( [0] => Array( [value] => 10 ) )
[3] => Array( [0] => Array( [value] => 10 ) )
)
I am working on a custom module in drupal and need to sum up the [value],
However I tried different approaches using array_column, array_sum, but didn't get the solution.
Any help would be appreciated. Thanks.
Code
$contributionDetails = $node->get('field_contributions')->getValue();
foreach ( $contributionDetails as $element ) {
$p = Paragraph::load( $element['target_id'] );
$text[] = $p->field_contribution_percentage->getValue();
}

Answer 1

You could make use of array_map here instead of an accumulator:
$arraySum = array_map(function ($v) {
return reset($v)['value'];
}, $text);
print_r(array_sum($arraySum)); // 120
Edit, as a full example:
$values = [
[['value' => 25]],
[['value' => 75]],
[['value' => 10]],
[['value' => 10]],
];
echo array_sum(array_map(function ($v) {
return reset($v)['value'];
}, $values)); // 120

A couple of loops and an accumulator is one way to achieve this
$tot = 0;
foreach ($array as $a){
foreach ($a as $b){
$tot += $b['value'];
}
}
echo $tot;
Or if you are sure there will always only be one occurance of the inner array.
$tot = 0;
foreach ($array as $a){
$tot += $a[0]['value'];
}
echo $tot;
Or using the code you just posted
$contributionDetails = $node->get('field_contributions')->getValue();
$tot = 0;
foreach ( $contributionDetails as $element ) {
$p = Paragraph::load( $element['target_id'] );
$text[] = $p->field_contribution_percentage->getValue();
$tot += $p->field_contribution_percentage->getValue();
}
echo $tot;

Answer 3

So you have an array containing 2 arrays which have the index 'value', you just need to loop each array using nested foreach and a variable $sum which sum up the value on each iteration.
Try this code:
<?php
$sum = 0;
foreach($array as $value) {
foreach ($value as $v){
$sum += $v['value'];
}
}
echo $sum;
This will output 120
