/* Additional Notes:
The remotequery.class.php client class simply converts XML data retruned
from the server into an easy to use array and contains a few extra parameters
(like row count, timer, and SQL). You can use other languages to convert the
XML returned from the remote_query_server.php file located on the server.
The actual returned XML (that is used in marshalling) from the
remote_query_server.php file (on the remote server) looks like this:
-----------------------------------------------------------------------------
<?xml version="1.0" ?>
<root rows="2" microseconds="0.00050081346729258" query="SELECT * FROM Test">
<row index="1">
<FirstName>John</FirstName>
<LastName>Doe</LastName>
<ZipCode>12345</ZipCode>
<Phone>555-1212</Phone>
</row>
<row index="2">
<FirstName>Jane</FirstName>
<LastName>Smith</LastName>
<ZipCode>54321</ZipCode>
<Phone>555-1212</Phone>
</row>
</root>
