Code to parse user agent string?

Questions:

As strange as I find this, I have not been able to find a good PHP function anywhere which will do an intelligent parse of a user agent string? Googled it for about 20 minutes now.

I have the string already, I just need something that will chop it up and give me at least browser/ver/os.

Know of a good snippet anywhere?

Answers:

The get_browser() function has been available in PHP for quite a long a time.

The PHP manual is free, can be downloaded in various formats and viewed online (with comments)

https://github.com/browscap/browscap-php – this is a standalone library that aims to replace get_browser function. For shared hostings it seems to be a better option.

Works on: PHP 5

Try out ThaDafinser/UserAgentParser it’s an abstraction for many available user agent parsers.

So if you are not happy with one – just switch to another (or combine them)

You can try it out here

There is a PHP class library i found out, and it has worked so well for me. It is in the link below.

It is lightweight and just does what I wanted (Browser, Version, OS, Mobile/PC, and much more) in a memory-friendy manner.
