PHP Array Setup from Variable - php

Question

I have a list of items I want to feed to an API via an array but it is built from a separate object. I was thinking I could loop through the items in the object to construct a variable I could then feed to the array but something is disconnected. This is probably easier to see than it is to explain.
The code I am using is this:
//Set up the parser object
$parser = new XMLParser($xml);
$parser->Parse();
$skuList = '';
// Pull the inventory of the requested SKUs from Magento for comparison later
foreach($parser->document->product as $product)
{
$skuList .= "'" . $product->sku[0]->tagData . "',";
}
echo $skuList;
print_r( $proxy->call($sessionId, 'product_stock.list', array(array($skuList))));
If I run this at the command line I get
'1DAFPOT5','8GAIL','26BULK30',Array
(
)
Now if I change the print_r line by putting the contents of the variable directly in the call like this
print_r( $proxy->call($sessionId, 'product_stock.list', array(array('1DAFPOT5','8GAIL','26BULK30', ))));
I get this output which is what I am looking for
'1DAFPOT5','8GAIL','26BULK30',Array
(
[0] => Array
(
[product_id] => 2154
[sku] => 26BULK30
[qty] => 19.0000
[is_in_stock] => 1
)
[1] => Array
(
[product_id] => 2255
[sku] => 8GAIL
[qty] => 16.0000
[is_in_stock] => 1
)
[2] => Array
(
[product_id] => 2270
[sku] => 1DAFPOT5
[qty] => 23.0000
[is_in_stock] => 1
)
)
Am I constructing the variable incorrectly or do I need to feed it to the array differently?

$skuList looks like an array, but is still a string.
You have to do this after foreach loop:
$skuList = explode(',',$skulist);
Or, better, make skuList an array since beginnig:
$skuList = array();
foreach($parser->document->product as $product)
{
$skuList[] = $product->sku[0]->tagData;
}
print_r( $proxy->call($sessionId, 'product_stock.list', array($skuList)));
