PHP Magento API catalog_product.info not working when running through a list - api

Question

I am trying to create a magento API to get the pricing of each item. I have a table with all the SKU's i need to get info for. i ran the following for one item and it worked
$client = new SoapClient('http://www.mysite.com/api/soap/?wsdl');
$session = $client->login('user', 'pass');
$productId = 'ABC';
$att = array("visibility","sku","special_price", "price");
$arguments = array( $productId, NULL, $att);
$result = $client->call($session, 'catalog_product.info', $arguments);
echo $result['visibility'].",".$result['sku'].",".$result['special_price'].",".$result['price'];
the above code worked fine.
then i tested another code to make sure that my code to query the database and loop through each sku works
$getskus = "SELECT sku FROM items;";
$skus = mysqli_query($con, $getskus);
while($row = mysqli_fetch_array($skus))
{
$productId = $row['sku'];
echo $productId."<br>";
}
The above code works fine. My issue is when i combine the 2 i get a blank screen.
$client = new SoapClient('http://www.mysite.com/api/soap/?wsdl');
$session = $client->login('user', 'pass');
$getskus = "SELECT sku FROM items;";
$skus = mysqli_query($con, $getskus);
while($row = mysqli_fetch_array($skus))
{
$productId = $row['sku'];
$att = array("visibility","sku","special_price", "price");
$arguments = array( $productId, NULL, $att);
$result = $client->call($session, 'catalog_product.info', $arguments);
echo $result['visibility'].",".$result['sku'].",".$result['special_price'].",".$result['price'];
}
i get nothing. Any ideas?
update: if $row['sku'] = '9005' will magento think its a product id instead of a SKU?

This line:
$result = $client->call($session, 'catalog_product.info', $arguments);
This can't accept $arguments as the third param. Instead:
$result = $client->call($session, 'catalog_product.info', $row['sku'], null, $att, 'sku');
NB: not sure if 'null' (4th param) is a valid argument for store view. To be safe, replace with the correct store view (default, in most cases).
