Answer 1

When someone comments and asks Please show input and expected output. this is not done to give you more work, but there are many ways to achieve what you want but many answers can be wrong or require much more code (as with the accepted answer).
Presuming this is your data:
$rawData = [
['month_no' => 1, 'month_count' => 1],
['month_no' => 2, 'month_count' => 1],
['month_no' => 3, 'month_count' => 1],
['month_no' => 4, 'month_count' => 1],
['month_no' => 1, 'month_count' => 2],
['month_no' => 6, 'month_count' => 2],
['month_no' => 7, 'month_count' => 6],
['month_no' => 12, 'month_count' => 4],
];
Do you want just the summed up values?
<?php
$array = [];
foreach ($rawData as $data) {
$m = strtolower(DateTime::createFromFormat('!m', $data['month_no'])->format('M'));
$array[$m] = !isset($array[$m]) ? $data['month_count'] : $array[$m]+$data['month_count'];
}
print_r($array);

Array
(
[jan] => 3
[feb] => 1
[mar] => 1
[apr] => 1
[jun] => 2
[jul] => 6
[dec] => 4
)
Or do you want an array of all the months with the summed up values:
<?php
$array = [];
foreach (range(1, 12) as $month) {
$m = strtolower(DateTime::createFromFormat('!m', $month)->format('M'));
$monthSet = array_filter($rawData, function ($v) use ($month) {
return $v['month_no'] === $month;
});
$array[$m] = 0;
foreach ($monthSet as $data) {
$array[$m] += $data['month_count'];
}
}
print_r($array);

Array
(
[jan] => 3
[feb] => 1
[mar] => 1
[apr] => 1
[may] => 0
[jun] => 2
[jul] => 6
[aug] => 0
[sep] => 0
[oct] => 0
[nov] => 0
[dec] => 4
)
Or perhaps don't even care about the month's strings as your comment suggests.
<?php
$array = [];
foreach ($rawData as $data) {
$m = $data['month_no'];
$array[$m] = !isset($array[$m]) ? $data['month_count'] : $array[$m]+$data['month_count'];
}
print_r($array);

Array
(
[1] => 3
[2] => 1
[3] => 1
[4] => 1
[6] => 2
[7] => 6
[12] => 4
)
Its why we ask..

Answer 2

Please modify your code as follows
foreach($rawData as $Data)
{
$monthsss = $Data['month_no'];
if($monthsss=='1')
{
$arrayF['jan'] = is_null($Data['month_count'])? 0 : $Data['month_count'];
}
if($monthsss=='2')
{
$arrayF['feb'] = is_null($Data['month_count'])? 0 : $Data['month_count'];
}
}
