Express Alphanumeric Symbol Identification with Error Reduction

Easier is a base-27 encoder/decoder designed to reduce human error when inputting encoded strings.

The goal of Easier is to simplify transmitting data between humans and computers by collapsing glyphs of similar appearance. For example, humans often have difficulty determining whether they’re looking at a lowercase ‘l’ or a capital ‘I’. Easier makes this ambiguity immaterial.

Easier enables confidently sharing strings even in media where print quality or font choice may render some glyphs difficult to decipher. Easier-encoded strings are particularly useful in shortened URLs destined to be shared in print, written by hand, or glimpsed in passing.

If you use Packagist, add rfreebern/easier to the "requirements" section of your composer.json and run composer.phar update.

Include the library: use rfreebern\Easier as Easier;

Encode a decimal number: $encoded = Easier::encode(8675309);

Decode an Easier number: $number = Easier::decode($encoded);

Easier can also be used in object context:

$easier = new Easier(69105);
$encoded = $easier->encode();
$another = $easier->encode(1048576);

Easier has a full PHPUnit test suite. Simply run phpunit . in the Easier root directory.
