Browser Detection for enabling/disabling

[Anon]

I need some code to implement a browser detection method to disable javascript when Netscape is being used to view a web site. Netscape is lame when it comes to processing java and my site uses lots of it. Any ideas?

Look at $HTTP_USER_AGENT

search for:
MSIE IE,
or Mozilla/4 Netscape 4.x,
or Mozilla/5 Netscape 6.x

When javascript is coded for both browsers it works very well in all browsers (mozilla included). It is only when coded for IE that Netscape falls down. I have found that some wysiwyg editors don't write code that works with both. I write all my javascript for both. With that said I will admit that Netscape has gone down hill rapidly since being aquired by AOL.

There are lots of example scripts (mostly javascript) that will do browser detection out there,

Javascript:

A search on phpbuilder.com yielded 817 matches on the subject, obviously it has been asked/answered before.

I found this somewhere and added to it (as it was not able to recognise Konqueror or separate Netscape <6 from Netscape 6 prevoiusly) so try this, it filters for most.... any additions welcome to my email address if you please.
