添加一个具有开头为零的数字

Question

I have this variable $value1= 000001; which as you can see contains some numbers which begins with 0.

What I am trying to is add "1" with the variable so that when I echo it looks like this 000002. Again for example if the variable is like this $value1= 012001; I want to make it look like 012002.

I have tried like following but the result it produces is only "2"

$value1= 000001;  
echo $value+1;

Could you please show me how to achieve this?

thanks :)

Many ways to do this, here's a different one:

$value1 = '000101';

$strLen = strlen($value1);
$value  = (((int) $value1) + 1);
echo str_pad($value, $strLen, '0', STR_PAD_LEFT);

php test.php 000102
