Cony is a PHP library for convert integer into alphabet, and reversely too

Installation

composer require carry0987/cony

Note You can install bcmath extension in order to get better performance

Usage

require dirname(__DIR__).'/vendor/autoload.php';

use carry0987\Cony\Cony;

echo Cony::toNumeric('test'); // 4544743
echo '<br />';
echo Cony::toAlphanumeric(4544743); // test

If you want the alphaID to be at least 3 letter long, use the $padUp argument.

In most cases this is better than totally random ID generators because this can easily avoid duplicate ID's.

For example if you correlate the alpha ID to an auto incrementing ID in your database, you're done.

Cony::toAlphanumeric(4540899, 3); // test
Cony::toNumeric('test', 3); // 4540899

Although this function's purpose is to just make the ID short - and not so much secure, with third argument secureKey you can optionally supply a password to make it harder to calculate the corresponding numeric ID.

Cony::toAlphanumeric(11282993, 3, 'heuh2ui12'); // test
Cony::toNumeric('test', 3, 'heuh2ui12'); // 11282993

And, for final, you can easy transform alphanumeric result:

Cony::toAlphanumeric(21663528, 0, null, Cony::TRANSFORM_UPPERCASE); // B2TFK
Cony::toAlphanumeric(21663528, 0, null, Cony::TRANSFORM_LOWERCASE); // b2tfk
