Pagerank checker script problem

Hi,

I try to use the free pagerank checker class from Rick Lim, but I encounter this problem under PHP 5 (EasyPHP 2.0b1, Windows Vista) while it works fine under PHP 4 on a previous version of EasyPHP :

Fatal error: Call to undefined method rank::functions() in C:Program FilesEasyPHP 2.0b1wwwfunctions.class.php on line 145


The line that causes the problem :

function __construct () {
$this->functions();
}


Here is the Pagerank checker script : rank.class.php

<?php
include 'functions.class.php';
class rank extends functions {
var $url;
var $pagerank;
var $alexa_rank;
var $backlinks = array('google' => '', 'yahoo' => '', 'msn' => '', 'altavista' => '', 'alltheweb' => '');
var $dmoz;

#start
function __start () {
$this->url = preg_replace('/http:///si', '', $this->url);
$this->pagerank = $this->__pagerank();
$this->alexa_rank = $this->__alexa_rank();
$this->backlinks['google'] = $this->__backlinks('google');
$this->backlinks['yahoo'] = $this->__backlinks('yahoo');
$this->backlinks['msn'] = $this->__backlinks('msn');
$this->backlinks['altavista'] = $this->__backlinks('altavista');
$this->backlinks['alltheweb'] = $this->__backlinks('alltheweb');
}

function cleanup () {
$this->pagerank = $this->format_number($this->pagerank);
$this->alexa_rank = $this->format_number($this->alexa_rank);
$this->backlinks['google'] = $this->format_number($this->backlinks['google']);
$this->backlinks['yahoo'] = $this->format_number($this->backlinks['yahoo']);
$this->backlinks['msn'] = $this->format_number($this->backlinks['msn']);
