Php :: Create A Query From Flash Builder To MySQL With SelectedItems?

I am trying to create a query from Flash Builder to PHP/mySQL with selectedItems. I have a simple SELECT query set up to populate a datagrid of items I would like to select for main query (two records looks something like this "19 10","20 10"). This is where I get stuck. I don't know if I need to break down the selectedItems in Flash Builder for formatting in SQL or if I can do it in PHP.

I would assume that it should be done in Flash Builder and I would then send the partial SQL statement to PHP. As of right now, Flash Builder is holding the selected values as CustomObjects and I unsure of how to retrieve what is in the objects for formatting.

var arr:Array = dataGrid.SelectedItems

This yields an array of CustomObjets and I lost from there.I will need the resulting SQL statement would need to look something like this.

SELECT *
FROM Stats
WHERE neu IN ('19 10','20 10');
