Hey there,

This PHP script converts a MySQL table(query) to an XML output.
I use it with Macromedia Flash MX with the XML connection.

you cant use !empty as a value of 0 is defined as empty.

change it to:-

if(is_null($value))
{
  $data.=NULL;
}
else
{
  $data.=$value;
}

I cant see the example while typing this, so change it to whatever fits your code.
