append zero using sprintf with big values

Question

I need to append a number of zeros to a integer value,That number of zeros may be upto 20.

   echo sprintf("%020d",'123456789101112');

But i got the result

 00000000002147483647

This is wrong,I need to get 00000123456789101112,Does anyone know what is the problem?

Answer 1

you can use str_pad:

$value = "123456789101112";
echo str_pad($value, 20, '0', STR_PAD_LEFT);

Output

00000123456789101112
