PHP: How to convert bigint from int to string?

Question

I want to be able to convert big ints into their full string derivatives.

For example.

$bigint = 9999999999999999999;
$bigint_string = (string) $bigi         


        

Answer 1

Just store the value as string and display...!

   $bigint = '9999999999999999999';

    var_dump($bigint);

Output:

string(19) "9999999999999999999"
