Sure you can do all kinds of things with a database but I try to avoid unnecessary connection to the db because they are expensive. It all comes down to how badly you want to prevent the same message to be sent twice. I have seen bots submit the same message from multiple IPs and some will even modify the message a bit by adding some random data to the end. So I am not sure how effective a simple md5 check will be. -- John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] PHP within XML?
I am trying to figure out if it is possible to have PHP work within an XML document. The application is tracking RSS subscribers IP addresses within the database. I have wrote functions so the PHP code required is below is minimal, after the XML declaration line. Prior to posting this question I tried to have the PHP at the very start, but that doesn’t work, the declaration line needs to be first. Right now the PHP is displayed as a comment. Thoughts anyone? Ron === ?xml version=1.0 encoding=utf-8? ?php #load RSS XML function require_once(rss_subscribers_xml.php); $ip_address = _ip; rss_subscriber_update($ip_address); ? RSS content starts here === Ron The Verse of the Day “Encouragement from God’s Word” http://www.TheVerseOfTheDay.info

Ash True, it is a message which has been intentionally modified to appear different even though 99.9% of the content is the same. Most humans will view the message as the same but it is not. Anyway, the OP should have a few ideas now how to implement something that may work for his scenario. -- John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ron How are you executing the XML file? By calling it with your browser? You may need to tell your webserver that you want to treat your xml file as a PHP document. You can use .htaccess for this and add something like this: Files YourXMLFile ForceType application/x-httpd-php /Files Hope this helps. -- John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Quoting Ron Piggott ron.pigg...@actsministries.org: I am trying to figure out if it is possible to have PHP work within an XML document.

Prior to posting this question I tried to have the PHP at the very start, but that doesn’t work, the declaration line needs to be first. Right now the PHP is displayed as a comment. In order for your PHP code to be processed the file should be named with a .php extension. Since you're writing XML code, you need to send an XML header type first: ?php header (Content-Type:text/xml); #load RSS XML function require_once(rss_subscribers_xml.php); $ip_address = _ip; rss_subscriber_update($ip_address); echo '?xml version=1.0 encoding=utf-8?' . \n; ? Rest of your XML content. This should work. Ken -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] How to catch an irregular end of an application?
Hi, what is the best practice to catch an irregular end of an application? The browser might crash or the user closes accidently the browser window decides to jump away to his favourite bloq without loging out of my application. Is there some way to let an javascript event trigger some ajax to store an exit time into my DB or make it mandatory to at least visit the logout.php before someone can surf away? regards -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
