Hello,
If I give out this code, and my server www.test.com supports php and I give people this piece of code: <script language="JavaScript" src="http://www.test.com/news/news.php"></script>
And someone puts this code on his page, but on a server that doesn't support php, will it work ?
yes it will work if the php script is on your server.
Remember, PHP is server-side, the only thing the user has to do is view the output.
