<?php
require_once 'app/Mage.php'; //path to app/Mage.php
Mage::app(); //run
Mage::getSingleton('core/session', array('name'=>'frontend')); //load customer session

$products = Mage::getModel('catalog/product');
$sku = '123'; //your sku here
$pid = $products->getIdBySku($sku); //product id
$product = $products->load($pid);
$qty = 1; //your quantity here

$cart = Mage::getModel('checkout/cart');
$cart->init();
$cart->addProduct($product, array('qty' => $qty));
$cart->save();

Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
echo "SKU [".$sku ."] was added to cart";
