Nooo, don't do that. When the client end does something like
GDownloadUrl(mydata.php) it has no idea what mydata.php actually is.
It need not be an actual file of results.
What many people do is write a script that is called mydata.php.
The script does the searching and does something like
echo "<xmldata>heres the data </xmldata>";
When this arrives at the client, it has no idea it isn't a real file,
and that it was created dynamically. It's just data.
That's oversimplified, but from that starter, review the classic
example -

and it should al click into place.
