YouTube like ID

Translates a number to a short alphanumeric version

Requires:

PHP 7.0+

Installation:

composer require kvz/youtube-id

Usage:

Don't forget to:

use Kvz\YoutubeId\Converter;

Convert any number up to 9007199254740992 to a shorter version in letters e.g.:

Converter::toAlphanumeric(2188847690240); // C7nXQpS

Convert back from short version in letters to numbers:

Converter::toNumeric('C7nXQpS'); // 2188847690240

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.

Converter::toAlphanumeric(2188847690240, 3); // C7nXQpS
Converter::toNumeric('C7nXQpS', 3); // 2188847686396

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.

Converter::toAlphanumeric(1327301435881, 3, 'Shfu388291ssD'); // C7nXQpS
Converter::toNumeric('C7nXQpS', 3, 'Shfu388291ssD'); // 1327301435881

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

Converter::toAlphanumeric(2188847690240, 0, null, Converter::TRANSFORM_UPPERCASE); // C7NXQPS
Converter::toAlphanumeric(2188847690240, 0, null, Converter::TRANSFORM_LOWERCASE); // c7nxqps
