Where the values on keys clicks, cpm, ctr, impressions, reach, spend are added up ( there are not in my example above )

This should do what you want:

$props_to_sum = ["cpm", "clicks", "reach"];

$result = [];
foreach ($data as $entry) {
    $key = $entry[1]['shortname'];
    if (!array_key_exists($key, $result)) {
        $result[$key] = $entry;
        continue;
    }
    foreach ($props_to_sum as $prop) {
        $result[$key][0][$prop] += $entry[0][$prop];
    }
}
$result = array_values($result);

Actually I don't want to reduce the arrays! I want the arrays to be as is, just merged where 'shortname' is identical, and specific numeric values added up.
I think i understand, i'll try to come up with something.
If there f.x. are 3 different arrays with the shortname "Greve" I want those array merged into a single array with the shortname "Greve" with all the numeric values are added up, if array1 have a REACH = 5000, array2 REACH = 4000, array3 REACH = 10000, the new array will have a REACH of 19000, but I will still want all the same keys, because I will use them to be displayed on a dashboard. But I am of course open for a better solution :-)
This looks great and it does merge the arrays so that I am ending up with just two arrays from my example in the original question. But it looks like it doesn't add up the values ... I have testet on the shortname "greve" where total clicks should be 565, but it is taking the value from the first array with shortname greve with value 102.
