PHP Rot Encoding

Tip: Rename this md file to php to test it on your web server.

<?php

require 'src/Rot.php';

$str = "Have you not heard the stories? Captain Barbossa and his crew of miscreants sail from the dreaded
        Isla de Muerta. It's an island that cannot be found except by those who already know where it is.";

$rot = new Nggit\PHPRotEncoding\Rot($str);

Encode the string using pin 2154

$encoded = $rot->encode(2154);
// Or separate by commas:
// $encoded = $rot->encode(2, 1, 5, 4);
echo '<br />';

Display the encoded string

echo $encoded;
// Hsst hbboeeBp alxanI l. bi torsu.aiadrtftrotwoeu?c ina ata reoysh atkwancdost r� au i 'twie nsr t ah
//  m idrfyesi vo d sneetr etp ey aeeednas fht�I eeMachhdnaowls er n l s hs nctda�mea dnCihos�deraoo
echo '<br />';

Decode the encoded string

echo $rot->decode();
// Have you not heard the stories? Captain Barbossa and his crew of miscreants sail from the dreaded
// Isla de Muerta. It's an island that cannot be found except by those who already know where it is.
echo '<br />';

Decode the encoded string using another instance

$rot1 = new Nggit\PHPRotEncoding\Rot($encoded);
echo $rot1->decode(2154);
// Have you not heard the stories? Captain Barbossa and his crew of miscreants sail from the dreaded
// Isla de Muerta. It's an island that cannot be found except by those who already know where it is.
echo '<br />';

What if the pin doesn't match?

echo $rot1->decode(124);
// Hh ertoaen d uvaoyc mwscfrhi r eisoan eoittfsamlsr eh ed ae dr d lwha e rhoda keosyhaes repsttCi ?oBt
