Fetch paging-cookie

Hi all,

I am doing, with the PHP-SDK 2011 library, a function that returns the count of a query. But I have a problem if the request is higher than 5000 records. I read that I have to use ´paging-cookie´ like this:

$query = '<fetch count="' . $count . '" page="' . $page . '" paging-cookie= "' . $cookie . '" >

<cookie page="2"><accountid last="{99323674-8166-E411-9030-D89D67645050}" first="{F4E63630-F068-E411-B918-6C3BE5BEFE80}" /></cookie>

But the XML has double quotes and this provoque that the request fails.

Did anybody have this problem working with PHP library?

Thanks, bests.
