Scripts — Browser & OS Detection — Javascript & PHP

Welcome to our PHP and Javascript browser detection script download area. We hope these scripts will be useful to you, especially given how problematic some CSS can be in terms of cross browser solutions and debugging.

Your Computer Box

We've been asked how to implement the "Your Computer Information" box on this page, so we put it in a script.

PHP Browser Detection

Run Time: 0.00024009 Seconds

All scripts have been thoroughly tested, although of course no script is ever perfect, so they will be modified as time goes by. There is a 'last modified by' date scripted in next to each download so you can see if it has changed from the version you have. If you find any bugs or detection failures, please post them in our web programming forum. If you do find something wrong with one, and we'll get it fixed.

Some of the Browser Detector Scripts also include OS detection, the PHP browser detector is much more complex than the Javascript browser detectors, and includes Unix, Linux, and Mac OS X, along with Windows NT and 9x detection.

[ the browser detector to your left is running off of the PHP browser detection script, which is far more powerful than the javascript version, although both do their jobs well ]


Please Link to our Site

It would really help us out, and help other people find this information, if you could add a link to our site in exchange for these scripts. Thanks.

The Navigator User Agent

User Agent List

If you need a list of user agents, try this one or this one. There's also a very nicely done useragent list on here.

All browser detector scripts use the browser Navigator Agent provided by the browser. If this is modified or missing, there is no way for anyone to detect what browser you are using. Fortunately, only geeks think it's cool to modify their navigator user agent strings. Most people, the overwhelming majority of your site's visitors, have no idea such a thing even exist, so you should in general be in good shape.

Navigator User Agent strings look like this, all browsers and spiders have some version of them. In this case the browser is Mozilla Firebird 0.7 running on Windows 2000 Operating system:

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 Firebird/0.7

This is your browser useragent string:

CCBot/2.0 (http://commoncrawl.org/faq/)
