Third time lucky! I missed out on some subtleties in the question originally. Try the following code - it's a bit loopy but it should work for you.
I am assuming that your original array is called $data.
// first we need to 'normalise' or fill in the blanks in the contents of the sub array
// get a unique list of all the keys shared - doing it manually here
$keys = ['Support Help Desk', 'Business Activity', 'Maintenance Tasks', 'Development', 'Consulting Services'];
// create a default array with $keys, assigning 0 as the value of each
$default = array_fill_keys($keys, 0);
// next fill in the blanks...
// get the diff (missing keys) between the current element and the default array
// merge the missing key/value pairs
array_walk($data, function(&$month, $key, $default) {
$diff = array_diff_key($default, $month);
$month = array_merge($diff, $month);
}, $default);
// now the array is normalised
// flatten the array... where there are duplicate values for a key, and
// there will be in all cases now including default values
// a sub array is created
$merged = call_user_func_array('array_merge_recursive', $data);
// finally loop over the merged array
// and implode each array of values into a comma separated list
foreach ($merged as &$element) {
if (is_array($element)) {
$element = implode(', ', $element);
}
}
// done :)
var_dump($merged);
Yields:
array (size=5)
'Business Activity' => string '0, 1.92' (length=7)
'Maintenance Tasks' => string '0, 1' (length=4)
'Support Help Desk' => string '24.67, 14.38' (length=12)
'Development' => string '7.74, 2.11' (length=10)
'Consulting Services' => &string '4.04, 0' (length=7)
Hope this helps :)

Let's say your array is stored in $main_arr and result array is $result_arr.
$result_arr = array();
foreach ($main_arr as $month) {
foreach ($month as $key => $val) {
if (!isset($result_arr[$key])) {
$result_arr[$key] = array($val);
} else {
array_push($result_arr[$key], $val);
}
}
}
foreach ($result_arr as $key => $val) {
$result_arr[$key] = implode(', ', $val);
}
print_r($result_arr); //Final output.
