$da = 1;
$cal_sunday = $da + 7;
printf('%02s', $cal_sunday);

printf() and sprintf() work similarly, except the first does a direct output, while the later returns the value so it can be assigned to another variable.

$da = 1;
$cal_sunday = sprintf('%02s', $da + 7);
echo $cal_sunday;

Have a look at the sprintf function

Your calculation produces and integer but you require a string.

Use sprintf to return the string in the format you need.

You can use sprintf to format your number:

echo sprintf('%02u', $cal_sunday);
