turn a number based on passed in value to at least 6 digit and max 8 digit

public static function generateReceiptNumber(int $id)
{
     $receipt_number = sprintf('%06d', $id % 100000000);
     return $receipt_number;
}

I am having the above code to help me to transform a passed in $id to a minimum 6 digit and maximum 8 digit number. eg: 000001 - 99999999

But this code has a flaws that when the $id equal to 100000000, it will return me 000000,
how can i enhance the code above to give me 000001 instead?

So and so forth, the $id is the database incremental id.

The purpose of wanted to achieve this is because, i have a display text box which the text limit is only 8 digit, i can only restarted the number back to 000001 and continue the count to repeat.

How about this:

function generateReceiptNumber(int $id)
{
	while($id>=100000000)
		$id -= 100000000 - 1;
	return sprintf('%06d', $id);
}

public static function generateReceiptNumber(int $id)
{
    // Handle the special case when $id is 100000000
    if ($id === 100000000) {
        return '000001';
    }

    // Use modulo to limit the ID to the range 0 to 99,999,999
    $limited_id = $id % 100000000;
    
    // Format the limited ID with leading zeros to ensure at least 6 digits
    $receipt_number = sprintf('%06d', $limited_id);
    
    return $receipt_number;
}

please check this answer if it will help you.
