PHP : Convert(cast) bigInt to string

Problem :

In PHP, you want to convert(cast) a big integer value to string for display.

Solution :

Use GNU Multiple Precision's gmp_strval() function to convert the big integer value to string.

For example :

 $bigInt = gmp_init("123456789123456789");
 $bigIntStr = gmp_strval($bigInt);
 echo $bigIntStr."\n";

Notes :

See on how to get GMP installed on your server.
