Suggestion: detect bots

[donatj]

They don't really have anything in common that I can grab onto, so it would require a hard coded list of "bots". That's not really practical at this point while still trying to keep this thing minimal I'm afriad.

In my website I added a check to know if the client is a bot or not. After calling parse_user_agent, if $user_agent['platform'] is NULL I just run this regex, which seems reliable to detect all the major bots (considering that it is run after user agent detection failed, false positive are almost impossible). I paste it here in case it can be useful :-)
preg_match('/bot|crawl|slurp|spider|cloudflare/i', $_SERVER['HTTP_USER_AGENT'])

(Now) there are some bots in Currently Detected Browsers.

echo $ua->platform() . PHP_EOL;
echo $ua->browser() . PHP_EOL;
echo $ua->browserVersion() . PHP_EOL;

Is it possible to add $ua->isBot()?

@luigifab Per the README,

This is not meant as a browser "knowledge engine" but rather a simple parser. Anything not adequately provided directly by the user agent string itself will simply not be provided by this.

There is no reliable way to know if something is a bot or not without maintaining a list of UA's known to be bots.

@lucaferrario 's method of checking if the platform is null may or may not be good enough for your purposes, but it's not reliable enough to codify.
