[16] => Array

You can see from the output not all days have loads. Day 5 and Day 13 are missing. I want to loop and create a new array and if there are no loads for that day add the day with zero loads.
I have been struggling with this. It seems that it would be simple but I can't seem to get it. Can someone here please help me?
I am extremely thankful.
Here is what I have so far:
$dayCountArr = [];
for ($i = 1; $i <= 31; $i++) {
$tempArr = [];
foreach ($dayO as $d) {
if ($d['day'] == $i) {
$day = $d['day'];
$loads = $d['Loads'];
} else {
$day = $i;
$loads = 0;
}
$dayCountArr[] = [$day, $loads];
}
}
Here is query. It returns the above output
SELECT
DATE_FORMAT(r.ship_date, '%d') AS day,
COUNT(DISTINCT(r.order_number)) AS 'Loads'
FROM table r
WHERE YEAR(r.ship_date) = '2022'
&& MONTH(r.ship_date) = 3
&& r.team = 'TEAM-2'
&& (r.order_status = 'Progress' || r.order_status = 'Delivered')
GROUP BY DATE_FORMAT(r.ship_date, '%d')

I assume your sql array is in $dayO and days are in preceding 0 format, I created load array for available days and assigned them to new dayCountArray. I applied str_pad to avoid keys 1(numeric) and use 01(string)
$dayCountArr = array();
foreach($dayO as $day){
$load[str_pad($day['day'], 2, "0", STR_PAD_LEFT)] = $day['Loads'];
}
for ($i = 1; $i <= 31; $i++) {
//Generating keys ('01','02',..,'31')
$key = str_pad($i, 2, "0", STR_PAD_LEFT);
//Assign 0 if Loads not available for $key
$dayCountArr[] = array('day' => $key,'Loads' => isset($load[$key])?$load[$key]:0);
}
print_r($dayCountArr);
