Summing objects property in array

Question

I have an array of objects, and i want to sum value of one of the properties, example:

Array
(
[0] => stdClass Object
    (
        [name] => jon
          


        

Answer 1

If you are using PHP 5.5

$arr_new = array_sum(array_column($yourarray, 'commission'));

Answer 2

Let's say $arr stores your information. Implement the following function:

function sumProperties(array $arr, $property) {

    $sum = 0;

    foreach($arr as $object) {
        $sum += isset($object->{$property}) ? $object->{$property} : 0;
    }

    return $sum;
}

After that you just have to call sumProperties($array, 'commission').

Furthermore if you have more properties that could be summed, you could replace commission with those properties.

Answer 3

$sum = 0;
foreach($arrObj as $key=>$value){
  if(isset($value->commission))
     $sum += $value->commission;
}
echo $sum;

Answer 4

array_reduce could be one way to do it; Just simply add your $array

$sum = array_reduce($array, function($carry, $item)
{
    return $carry + $item->commission;
});

var_dump($sum);
