Funcion para calcular el tamaño de las paginas 1

[Corretja11]

Despues lo ejecuto con este fichero (sample.webpagesize.php)

<?php
//don't forget to set time limit, because this class eats a lot of time :)
set_time_limit(900);
include("class.webpagesize.php");

$size = new WebpageSize;
//$size->setURLviaProxy("Pagina Web","PROXY03","80");
$size->setURL("Pagina web");
$size->printResult();


?>





Al ejecutar me da los siguientes errores:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in C:\AppServ\www\class.webpagesize.php on line 226

Warning: Variable passed to each() is not an array or object in C:\AppServ\www\class.webpagesize.php on line 155

Warning: array_unshift() [function.array-unshift]: The first argument should be an array in C:\AppServ\www\class.webpagesize.php on line 63


A ver si me podeis echar una mano. Gracias
