browscap ini directive not set

I'm using the get_browser() function in an attempt to warn people that their browser doesn't support Javascript. Actually I'm using it to tell them they can use certain parts of a web application I'm building. I've decided to properly use Javascript because I'm tired of listening to developers that are scared of using it and I've seen some great potential in the language. I digress, here is the error.

> browscap ini directive not set

Now I'd imagine this means I need somthing set it the php.ini. Can someone give me some direction on this one?

I don't think this is the "best" solution to detect is a browser supports what you need for your website :

• first of all, browsers can lie -- they can send whatever thay want as User-Agent
  • And even if a given version of a support should support what you need, Javascript can still be disabled.
• second, there are more "proper" way to detect what a browser can do or not, when it comes to Javascript.

For the second point, you should test if the browser actually supports what you need -- and not rely on a list such as the browscap one.

Still, to answer your question about browscap : there is a note at the bottom of the manual page for get_browser that says (quoting) :

> Note: In order for this to work, your browscap configuration > setting in php.ini must point to the > correct location of the browscap.ini > file on your system. browscap.ini is > not bundled with PHP, but you may find > an up-to-date » > php_browscap.ini file here. >
While browscap.ini contains > information on many browsers, it > relies on user updates to keep the > database current. The format of the > file is fairly self-explanatory.

So, you have to :

• download the browscap file,
• and set the browscap directive in your php.ini file, so it points to the file you downloaded.

I know this topic is old, but you can use something like:

<noscript>JavaScript must be enabled</noscript>

to display if JavaScript is not enabled.

You can check the browser by using Browser class download it from Github

Configuration

      include(/your-path/Browser.php);
$browser = new Browser();
    if( $browser->getBrowser() == Browser::BROWSER_IE && $browser->getVersion() >= 8 ) 
        {
            echo "Your browser is Internet explorer version 8";                                                                                                                                    
    }

There is a bug in PHP that can also result in this error when the real problem is that the web server can't read the browscap file (e.g., if it's owned by root instead of www-data). See https://bugs.php.net/bug.php?id=74501
