HTTP_REFERER will do the job, thanks!

You might want to check the HTTP_REFERER value; test the program from a
browser and the swf, and see what happens. Alternatively you could use a
GET parameter like
http://example.com/yourscript.php?calledby=swf
Be aware that anything sent back from the client can be spoofed - and
HTTP_REFERER can be altered or disabled - so it probably wouldn't be
hard for someone to make it appear to your script that it is being
called by your SWF.
If you're really concerned about restricting the communication between
the Flash movie and your server, there might be some way to build a
challenge-response mechanism into the flash; I don't know much about it.
If, on the other hand, you just don't want to confuse someone who might
accidentally run the XML-generating script from the browser, checking a
GET parameter as above is probably the safest. If it's not set properly,
redirect the user, eg:
if (!isset($_GET['calledby']) || $_GET['calledby'] != 'swf') {
header('Location: http://example.com/thecorrectpage.html');
exit();
}

Install Firebug extension for your Firefox browser Load your page in the browser with firebug running Watch the calls being made and that should answer the question You can also look at the web server logs to see which page is calling your script.

May the get_Browser function could tell you if it's from the .swf ? http://us.php.net/manual/en/function.get-browser.php H u g o H i r a m wrote: Hello I have a swf that runs a PHP script that generates a XML, on the PHP is there any way to detect if the file is being called from the swf or from the browser? because I want to avoid the file being run directly from the browser or from any other file than the swf. regards, Hugo. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
