I'm trying to use the php url shortener from here : https://github.com/delight-im/ShortURL
I just copyed this code and tried with a number, but I've a php error "Call to undefined function encode()". I can't find the problem.
Can you help me
Here is my code :
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Document sans titre</title>

<body>
<?php
/**
* ShortURL: Bijective conversion between natural numbers (IDs) and short strings
*
* ShortURL::encode() takes an ID and turns it into a short string
* ShortURL::decode() takes a short string and turns it into an ID
*
* Features:
* + large alphabet (51 chars) and thus very short resulting strings
* + proof against offensive words (removed 'a', 'e', 'i', 'o' and 'u')
* + unambiguous (removed 'I', 'l', '1', 'O' and '0')
*
* Example output:
* 123456789 <=> pgK8p
