RE: [PHP] Re: Mailing list

Should be relatively easy. Its going to take 2 steps. Send out one of the images with a unique id per mailout, this could be the users email address if you wanted to tie in the data per user (may be illegal in some countries without users permission). eg first mail <html> bla blah <img src="webbug.php?id=1"> </html> next mail <html> bla blah <img src="webbug.php?id=2"> </html> ... webbug.php webbug.php will passthrough the image that you want to send - phpbuilder, webmonkey, and hotscripts all have sample code for this kind of thing online. Make the php script pass through the image to the browser (remember to set the relevant content type header), and count the unique id in a database (i think due to image reload, count unique id's returned rather than number of reads) eg if user 1 reads email database should add user, count=count+1 to database for user reply read stats do a select count distinct (user) type sql query. This is called a webbug usually, most spammers use something like this. Remember not everyone reads mail online. So this technique will not work for offline mail readers, and those who don't use html compatible mailers. Also some email program's will autopreview mail, so a returned id, doesn't necessarily mean that the user has read it, only that their mail software has. No code, just theory here, but should be relatively easy to implement. Lawrence -----Original Message----- From: Richard Lynch [mailto:ceo@l-i-e.com] Sent: September 12, 2001 12:51 PM To: Sheni R.

But you either have to assume people only read it once, or count IPs and ignore AOL/DHCP/Hotmail etc users whose IPs will change more or less at random. -- WARNING richard@zend.com address is an endangered species -- Use ceo@l-i-e.com Wanna help me out?
