Change of content notification

Php updates the xml files in certain period of time. Is t开发者_StackOverflow中文版here any possible way to send a change of content notification from php to flash application. Thanks in advance

Assuming that the PHP runs on your server and the flash is in your web browser, then no. Best you can do is let the PHP side allow the flash side to ask if the content changed and then poll from the flash side.
