It's slightly more complicated than that (I'm a newbie too, but I know a very little about user-agent strings), but it *will* involve using http://www.php.net/manual/en/function.get-browser.php As you may be aware, IE's user-agent string was originally designed to look as similar to Netscape's as possible to avoid the idiots who block non-Netscape users[0], but there are some differences. Usually checking for "MSIE" in the string is enough. Here's a sample IE string: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Hotbar 2.0) This tells us it's IE6, running on Windows '98, and the user has Hotbar installed. And here's a sample Netscape Navigator 4: Mozilla/4.5 [en] (Win98; I) This tells us it's Navigator 4.5, looking for english pages, running on Windows '98. Anyone who tells me what the "I" stands for wins 3 cool points. Of course, sometimes browsers (like Konqueror, or Opera) are set up to spoof IE or Netscape, for the same reason IE was given the "Mozilla/4.0" string in the first place. In the case of Konqueror, the entire UA-string is configurable by the user, but for Opera, the browser's name is always included somewhere. Here's one for Opera: Mozilla/4.0 (compatible; MSIE 5.0; Linux 2.4.2-2 i686) Opera 5.0 [en] This tells us it's Opera 5, looking for english pages, running on Linux (kernel 2.4.2, Intel), and pretending to be IE5. It's easy to work out what a browser's user-agent string is. What's /not/ easy is telling a computer to work out what *browser* it is. You can just do a simple search for "MSIE" in the string, which will prevent you from blocking out spoofers[1] from your script and give you less accuracy, but would also provide relatively little work and successfully separate Netscape from IE-and-spoofers :o). One thing to remember: there's more than just Netscape out there. There's Mozilla, there's Opera, there's Dillo, there's Lynx, there's Links, there's Konqueror, there may even be a few poor fools stuck on Mosaic or Cello. And what if someone has no browser, and just uses wget and their favourite text viewer? [0] Oh, the irony! Look at what clueless "designers" are doing to block non-IE users today :o) [1] But then, I doubt you'd want to do that anyway... right? -- Mark Gallagher http://cyberfuddle.com/infinitebabble/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
