Improvement to php base_convert
function with support for large arbitrary number
Install
Via Composer
$ composer require phlib/base_convert
Usage
Trying in php fails
// convert big number from base 10 to 36 $largeNumber = '111222333444555666777888999000'; $base36 = base_convert($largeNumber, 10, 36); // notice no error from php on the failure to convert var_dump($base36); // fails to convert back var_dump($largeNumber == base_convert($base36, 36, 10));
Replace with phlib\base_convert and now it works
<?php require_once 'vendor/autoload.php'; use function Phlib\base_convert; // convert big number from base 10 to 36 $largeNumber = '111222333444555666777888999000'; $base36 = base_convert($largeNumber, 10, 36); var_dump($base36); // succesfully converts back var_dump($largeNumber == base_convert($base36, 36, 10));
Making it clearer you're using a different function
require_once 'vendor/autoload.php'; // convert big number from base 10 to 36 $largeNumber = '111222333444555666777888999000'; $base36 = Phlib\base_convert($largeNumber, 10, 36); var_dump($base36); // succesfully converts back var_dump($largeNumber == Phlib\base_convert($base36, 36, 10));
