Any php code to detect the browser with version and operating system?

Viewed   63 times

I tried to search in google but cannot find a complete solution (i only find something detects only the browser's type like firefox, opera) .

i want a php class or code to check the user's Browser including the version and also the operating system.

Thanks

I used the techpatterns.com one and they don't always update it and it use procedural code which feel dated...

The Wolfcast BrowserDetection PHP class is updated and use an Object-Oriented way to do it:

You use it this way:

$browser = new BrowserDetection();
echo 'You are using ', $browser->getBrowser(), ' version ', $browser->getVersion();

Another example:

$browser = new BrowserDetection();
if ($browser->getBrowser() == BrowserDetection::BROWSER_FIREFOX && $browser->compareVersions($browser->getVersion(), '5.0.1') !== 1) {
    echo 'You have FireFox version 5.0.1 or greater. ';
}

Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):

$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>

The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):

vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages.  More than one package may be
specified at once.  Prefix with channel name to uninstall from a
channel not in your default channel (pecl.php.net)

Options:
  ...
  -r, --register-only
        do not remove files, only register the packages as not installed
  ...

The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).

Detecting browser's details:

var nVer = navigator.appVersion;
var nAgt = navigator.userAgent;
var browserName  = navigator.appName;
var fullVersion  = ''+parseFloat(navigator.appVersion); 
var majorVersion = parseInt(navigator.appVersion,10);
var nameOffset,verOffset,ix;

// In Opera, the true version is after "Opera" or after "Version"
if ((verOffset=nAgt.indexOf("Opera"))!=-1) {
 browserName = "Opera";
 fullVersion = nAgt.substring(verOffset+6);
 if ((verOffset=nAgt.indexOf("Version"))!=-1) 
   fullVersion = nAgt.substring(verOffset+8);
}
// In MSIE, the true version is after "MSIE" in userAgent
else if ((verOffset=nAgt.indexOf("MSIE"))!=-1) {
 browserName = "Microsoft Internet Explorer";
 fullVersion = nAgt.substring(verOffset+5);
}
// In Chrome, the true version is after "Chrome" 
else if ((verOffset=nAgt.indexOf("Chrome"))!=-1) {
 browserName = "Chrome";
 fullVersion = nAgt.substring(verOffset+7);
}
// In Safari, the true version is after "Safari" or after "Version" 
else if ((verOffset=nAgt.indexOf("Safari"))!=-1) {
 browserName = "Safari";
 fullVersion = nAgt.substring(verOffset+7);
 if ((verOffset=nAgt.indexOf("Version"))!=-1) 
   fullVersion = nAgt.substring(verOffset+8);
}
// In Firefox, the true version is after "Firefox" 
else if ((verOffset=nAgt.indexOf("Firefox"))!=-1) {
 browserName = "Firefox";
 fullVersion = nAgt.substring(verOffset+8);
}
// In most other browsers, "name/version" is at the end of userAgent 
else if ( (nameOffset=nAgt.lastIndexOf(' ')+1) < 
          (verOffset=nAgt.lastIndexOf('/')) ) 
{
 browserName = nAgt.substring(nameOffset,verOffset);
 fullVersion = nAgt.substring(verOffset+1);
 if (browserName.toLowerCase()==browserName.toUpperCase()) {
  browserName = navigator.appName;
 }
}
// trim the fullVersion string at semicolon/space if present
if ((ix=fullVersion.indexOf(";"))!=-1)
   fullVersion=fullVersion.substring(0,ix);
if ((ix=fullVersion.indexOf(" "))!=-1)
   fullVersion=fullVersion.substring(0,ix);

majorVersion = parseInt(''+fullVersion,10);
if (isNaN(majorVersion)) {
 fullVersion  = ''+parseFloat(navigator.appVersion); 
 majorVersion = parseInt(navigator.appVersion,10);
}

document.write(''
 +'Browser name  = '+browserName+'<br>'
 +'Full version  = '+fullVersion+'<br>'
 +'Major version = '+majorVersion+'<br>'
 +'navigator.appName = '+navigator.appName+'<br>'
 +'navigator.userAgent = '+navigator.userAgent+'<br>'
)

Source JavaScript: browser name.
See JSFiddle to detect Browser Details.

Detecting OS:

// This script sets OSName variable as follows:
// "Windows"    for all versions of Windows
// "MacOS"      for all versions of Macintosh OS
// "Linux"      for all versions of Linux
// "UNIX"       for all other UNIX flavors 
// "Unknown OS" indicates failure to detect the OS

var OSName="Unknown OS";
if (navigator.appVersion.indexOf("Win")!=-1) OSName="Windows";
if (navigator.appVersion.indexOf("Mac")!=-1) OSName="MacOS";
if (navigator.appVersion.indexOf("X11")!=-1) OSName="UNIX";
if (navigator.appVersion.indexOf("Linux")!=-1) OSName="Linux";

document.write('Your OS: '+OSName);

You can do a significant amount of the work without assembly. Linux or NetBSD doesnt have to be completely re-written or patched for each of the many targets it runs on. Most of the code is portable and then there are abstraction layers and below the abstraction layer you find a target specific layer. Even within the target specific layers most of the code is not asm. I want to dispell this mistaken idea that in order to program registers or memory for a device driver for example that you need asm, you do not use asm for such things. You use asm for 1) instructions that a processor has that you cannot produce using a high level language. or 2) where high level language generated code is too slow. For example in the ARM to enable or disable interrupts there is a specific instruction for accessing the processor state registers that you must use, so asm is required. but programming the interrupt controller is all done in the high level language. An example of the second point is you often find in C libraries that memcpy and other similar heavily used library functions are hand coded asm because it is dramatically faster.

Although you certainly CAN write and do anything you want in ASM, but you typically find that a high level language is used to access the "hardware directly (like registers, memory locations, etc...)". You should continue to re-inforce your C skills not just with the K&R book but also wander through the various C standards, you might find it disturbing how many "implementation defined" items there are, like bitfields, how variable sizes are promoted, etc. Just because a program you wrote 10 years ago keeps compiling and working using a/one specific brand of compiler (msvc, gcc, etc) doesnt mean the code is clean and portable and will keep working. Unfortunately gcc has taught many very bad programming habits that shock the user when the find out they didnt know the language a decade or so down the road and have to redo how they solve problems using that language.

Never used any of those, but they look interesting..

Take a look at Gearman as well.. more overhead in systems like these but you get other cool stuff :) Guess it depends on your needs ..
