What Is This

Helps detect the user's browser and platform at the PHP level via the user agent.

Installation

You can add this library as a local, per-project dependency to your project using Composer:

composer require widgit/browser

If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:

composer require --dev widgit/browser

You can also download the latest developer copy of the Browser library by cloning this GitLab repository, or downloading it as a ZIP file here

Typical Usage

$browser = new Browser();
if (
    $browser->get_browser() === Browser::BROWSER_FIREFOX &&
    $browser->get_version() >= 10
) {
    echo 'You have Firefox version 10 or greater';
}

• Internet Explorer (Browser::BROWSER_IE)
• Pocket Internet Explorer (Browser::BROWSER_POCKET_IE)
• Galeon (Browser::BROWSER_GALEON)
• Konqueror (Browser::BROWSER_KONQUEROR)
• iCab (Browser::BROWSER_ICAB)
• OmniWeb (Browser::BROWSER_OMNIWEB)
• Phoenix (Browser::BROWSER_PHOENIX)
• Firebird (Browser::BROWSER_FIREBIRD)
• UCBrowser (Browser::BROWSER_UCBROWSER)
• Firefox (Browser::BROWSER_FIREFOX)
• Mozilla (Browser::BROWSER_MOZILLA)
• Palemoon (Browser::BROWSER_PALEMOON)
• curl (Browser::BROWSER_CURL)
• wget (Browser::BROWSER_WGET)
• Amaya (Browser::BROWSER_AMAYA)
• Lynx (Browser::BROWSER_LYNX)
• Safari (Browser::BROWSER_SAFARI)
• Playstation (Browser::BROWSER_PLAYSTATION)
• iPhone (Browser::BROWSER_IPHONE)
• iPod (Browser::BROWSER_IPOD)
• Google.s Android(Browser::BROWSER_ANDROID)
• Google.s Chrome(Browser::BROWSER_CHROME)

• Yahoo!.s Slurp(Browser::BROWSER_SLURP)
• W3C.s Validator(Browser::BROWSER_W3CVALIDATOR)
• BlackBerry(Browser::BROWSER_BLACKBERRY)

Operating System Detection

This solution identifies the following Operating Systems:

• Windows (Browser::PLATFORM_WINDOWS)
• Windows CE (Browser::PLATFORM_WINDOWS_CE)
• Apple (Browser::PLATFORM_APPLE)
• Linux (Browser::PLATFORM_LINUX)
• Android (Browser::PLATFORM_ANDROID)
• OS/2 (Browser::PLATFORM_OS2)
• BeOS (Browser::PLATFORM_BEOS)
• iPhone (Browser::PLATFORM_IPHONE)
• iPod (Browser::PLATFORM_IPOD)
• BlackBerry (Browser::PLATFORM_BLACKBERRY)
• FreeBSD (Browser::PLATFORM_FREEBSD)
• OpenBSD (Browser::PLATFORM_OPENBSD)
• NetBSD (Browser::PLATFORM_NETBSD)
• SunOS (Browser::PLATFORM_SUNOS)
• OpenSolaris (Browser::PLATFORM_OPENSOLARIS)
• iPad (Browser::PLATFORM_IPAD)

History and Legacy

Detecting the user's browser type and version is helpful in web applications that harness some of the newer bleeding edge concepts. With the browser type and version you can notify users about challenges they may experience and suggest they upgrade before using such application. Not a great idea on a large scale public site; but on a private application this type of check can be helpful.

This library is a fork of the Browser.php library by Chris Schuld which strives to keep the functionality of his version, while maintaining compliance with PHPCS and the WPCS and WidgitWPCS coding standards. By extension, WidgitWPCS compliance should also come very close to covering VIPWPCS standards.

The following quote from Chris explains his original motivation:

In an active project of mine we have a pretty graphically intensive and visually appealing user interface which leverages a lot of transparent PNG files. Because we all know how great IE6 supports PNG files it was necessary for us to tell our users the lack of power their browser has in a kind way.

Searching for a way to do this at the PHP layer and not at the client layer was more of a challenge than I would have guessed; the only script available was written by Gary White and Gary no longer maintains this script because of reliability. I do agree 100% with Gary about the readability; however, there are realistic reasons to desire the user's browser and browser version and if your visitor is not echoing a false user agent we can take an educated guess.

I based this solution off of Gary White's original work but have since replaced all of his original code. Either way, thank you to Gary. Sadly, I never was able to get in touch with him regarding this solution.
