How to add numeric value to value without adding or subtracting it in php

I would like to post a value to my MySQL database in this format;

01, 02, 03... 011, 012, 013... 0101, 0102, 0103, etc.

(with a 0 before each value).

If I do it like this "01+1" I (understandable) get the value 2 and not "02". is there a default php function that let's me set the default amount of characters or is there an other option?

I'm using laravel combined with eloquent and some own functions like so;

$lastSKU = $data->GetData('get', 'products', 'filter')->max('SKU');
$newValue = $lastSKU+1;

Thanks in advance.

It sounds like you won't know how the format will be, if there is always a 0 in front it is easy enough to do 

$value = '0'. ( $value + 1 );

PHP will automatically convert it to a number between the brackets and by adding a string to it it will become a string again.

Now if you do not know the the length or the padding in advance but you do need to keep the current padding I would suggest something like

$value = str_pad(($value + 1), strlen($value), '0', STR_PAD_LEFT);

Edit, str_pad is a bit slow these days, sprintf can do the same trick but much faster

$value = sprintf("%'.0" . strlen($value) . "d\n", ($value +1));
