Adding Arrays

[Nodral]

Hi

 

I have the following multidimensional array.

 

array => [0]

              ([apples]=>5,

                [pears]=>3,

                [bananas]=>6)

              [1]

              ([apples]=>2,

                [pears]=>4,

                [bananas]=>1)

              [2]

              ([apples]=>8,

                [bananas]=>2)

 

How can I iterate through it and produce one array with all the totals added up?

eg

array =>

              [apples]=>15,

                [pears]=>7,

                [bananas]=>9

 

I've tried googling , but can't seem to find the right thing.

Obviously these are example values, the arrays I'm using contain about 40 keys each, therefore this was easier to write / explain.

Replace $fruits with your array.

 

$totals = array();
foreach ($fruits as $fruit)
foreach ($fruit as $type => $val) {
	if (isset($totals[$type]))
		$totals[$type] += (int)$val;
	else
		$totals[$type] = (int)$val;
}
