Replace Product Names with a Loop - php

Question

I have a Magento webshop with several products in it. All of them begin with the word PRODUCT,
for example
PRODUCT 001.
I want to replace the word "PRODUCT" with "Article".
I tried to write a small script, but it's not working at all. Here is what I've got so far:
<?php
$_productCollection=$this->getLoadedProductCollection();
$_helper = $this->helper('catalog/output');
foreach($_productCollection as $_product)
{
$name = $_product->getName();
$new = str_replace("PRODUCT","Article", $name);
$_product->setName($new);
$_product->save();
};
?>
I did not really know how to run the script, so I added this into a CMS page and opened it:
{{block type="core/template" template="script.phtml"}}
What's wrong with it?

Create a file Replacename.php inside your magento root folder
and write the below code in that file and then execute it with below URL http://www.yourdomain.com/Replacename.php
<?php
require_once('app/Mage.php');
umask(0);
Mage::app();
$_productCollection = Mage::getModel('catalog/product')
->getCollection()->addAttributeToSelect('*');
foreach($_productCollection as $_product)
{
try
{
$name = $_product->getName();
$new = str_replace("PRODUCT","Article", $name);
$_product->setName($new);
$_product->save();
}
catch(Exception $e){
echo $e->getMessage();
}
}
