You can use str_pad -

echo str_pad($new, 2, "0", STR_PAD_LEFT);

str_pad()

Update

    $count_try = 10;
    $new = str_pad($count_try, 4, "0", STR_PAD_LEFT);
    echo $new;

thank's for the answer, i was us it but i have problem if i get the data in `$try` is more than 9 i will get the resul `$new=00010` but i want to get the result is `0010` – nanasjr Jun 18 '15 at 08:54
You dont have to concatenate that `$id` i think. Just set the socond parameter to `4` – Sougata Bose Jun 18 '15 at 08:57
hehe thanks i get it case close – nanasjr Jun 18 '15 at 09:08
@nanasjr - numbers prefixed with a `0` in PHP are treated as `octal` values, and `0008` is invalid octal and treated as `0` – Mark Baker Jun 18 '15 at 09:44
so i must use like what? i just want get number like that for numbering some data with tree structure data – nanasjr Jun 21 '15 at 16:51
For that it will work i think. give it a try. – Sougata Bose Jun 22 '15 at 04:04

Try this :

$id ="0010";
$new = (int) $id + 1;
$new = str_pad($new, 4, "0", STR_PAD_LEFT);
echo $new; //0011
