How can you handle missing months in an array filled with monthly values in PHP?

When dealing with missing months in an array filled with monthly values in PHP, you can loop through the array and check for any missing months. If a month is missing, you can insert it into the array with a default or null value to maintain the structure. 

// Sample array with monthly values
$monthlyValues = [
    'January' => 100,
    'February' => 150,
    'April' => 200,
    'June' => 180,
];

// Array of months to check against
$allMonths = [
    'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'
];

// Loop through all months and insert missing months with null value
foreach ($allMonths as $month) {
    if (!array_key_exists($month, $monthlyValues)) {
        $monthlyValues[$month] = null;
    }
}

// Sort the array by keys (months)
ksort($monthlyValues);

// Output the updated array
print_r($monthlyValues);
