$ua = (isset($_SERVER) && array_key_exists('HTTP_USER_AGENT', $_SERVER)) ? $_SERVER['HTTP_USER_AGENT'] : false;

// TRUE IF MOBILE DEVICE
$ismobile = (isset($_SERVER['AMF_ISMOBILE'])) ? $_SERVER['AMF_ISMOBILE'] : false;

	$mobile = ($ismobile) ? ' mobile' : '';
	switch($ua)
	{
		case stristr($ua, 'firefox') == true:
			$ver = explode('/',$ua);
			$ver = explode('.',$ver[count($ver)-1]);
			$o = 'firefox ff-'.$ver[0].' ff-'.$os;
		break;
		case stristr($ua, 'opr') == true:
			$ver = explode('/',$ua);
			$ver = explode('.',$ver[count($ver)-1]);
			$o = 'opera opera-'.$ver[0].' opera-'.$os;
		break;
		case stristr($ua, 'safari') != '' && stristr($ua, 'chrome') === false:
			$o = 'safari safari-'.$os;
		break;
		case stristr($ua, 'chrome') == true:
			$ver = explode('Chrome/',$ua);
			$ver = explode('.',$ver[1]);
			$o = 'chrome chrome-'.$ver[0].' chrome-'.$os;
		break;
		case stristr($ua, 'msie') == true:
			$ver = explode('MSIE ', $ua);

	return $o;
}

You can just paste the code above into a snippet and put a tag for the snippet where you want to use the USER_AGENT.

You'll have to explain how you want to use the USER_AGENT information if you need more than that.

yep, i make same...just paste the code in new snippet with name UserAgent and then i call my snippet like this: [[UserAgent]] or [[!UserAgent]] /or [[UserAgent?]] or [[!UserAgent?]]/, but i have no return results?

in regular php file to get the browser i use: <?php echo browser(); ?>

Your browser() function is never called.

Add this line at the very end (after the closing } of the function):

return browser();

Sorry, I don't see how that could happen if you're visiting from different browsers.

BTW, the $os lines should really be like this (though that's not the problem):

if(stripos($ua, 'windows') !== false) $os = 'win';

And the cases should be like this:

stripos($ua, 'firefox') !== false:

Sorry, I wasn't thinking. The problem is that the switch statement doesn't work that way. It just matches what's in the switch line to what's in the case line. You need to use if and elseif instead:

if (strpos($ua, 'firefox') !== false) {
    $ver = explode('/',$ua);
    $ver = explode('.',$ver[count($ver)-1]);
    $o = 'firefox ff-'.$ver[0].' ff-'.$os;

} elseif (stripos($ua, 'opr') !== false) {
    $ver = explode('/',$ua);
    $ver = explode('.',$ver[count($ver)-1]);
    $o = 'opera opera-'.$ver[0].' opera-'.$os;
} elseif (stripos($ua, 'safari') !== false && stripos($ua, 'chrome') === false) {
    $o = 'safari safari-'.$os;
} elseif (stripos($ua, 'chrome') !== false) {
    $ver = explode('Chrome/',$ua);
    $ver = explode('.',$ver[1]);
    $o = 'chrome chrome-'.$ver[0].' chrome-'.$os;
} elseif (stripos($ua, 'msie') !== false) {
    $ver = explode('MSIE ', $ua);
    $ver = explode('.', $ver[1]);
    $o = 'iexplore ie-'.$ver[0];
} else {
    $o = 'browserunknown';
}

I think this would be it (though $mobile is never used for anything or returned):

<?php

// GET THE USER_AGENT
$ua = (isset($_SERVER) && array_key_exists('HTTP_USER_AGENT', $_SERVER))
    ? $_SERVER['HTTP_USER_AGENT']
    : false;

// TRUE IF MOBILE DEVICE
$ismobile = (isset($_SERVER['AMF_ISMOBILE']))
    ? $_SERVER['AMF_ISMOBILE']
    : false;

if (stristr($ua, 'windows') != '') $os = 'win';
if (stristr($ua, 'mac') != '') $os = 'mac';
if (stristr($ua, 'linux') != '') $os = 'linux';
if (stristr($ua, 'android') != '') $os = 'android';
if (stristr($ua, 'iphone') != '') $os = 'iphone';
if (stristr($ua, 'ipad') != '') $os = 'ipad';

$mobile = ($ismobile) ? ' mobile' : '';

if (strpos($ua, 'firefox') !== false) {
    $ver = explode('/',$ua);
    $ver = explode('.',$ver[count($ver)-1]);
    $o = 'firefox ff-'.$ver[0].' ff-'.$os;

} elseif (stripos($ua, 'opr') !== false) {
    $ver = explode('/',$ua);
    $ver = explode('.',$ver[count($ver)-1]);
    $o = 'opera opera-'.$ver[0].' opera-'.$os;
} elseif (stripos($ua, 'safari') !== false && stripos($ua, 'chrome') === false) {
    $o = 'safari safari-'.$os;
} elseif (stripos($ua, 'chrome') !== false) {
    $ver = explode('Chrome/',$ua);
    $ver = explode('.',$ver[1]);
    $o = 'chrome chrome-'.$ver[0].' chrome-'.$os;
} elseif (stripos($ua, 'msie') !== false) {
    $ver = explode('MSIE ', $ua);
    $ver = explode('.', $ver[1]);
    $o = 'iexplore ie-'.$ver[0];
} else {
    $o = 'browserunknown';
}

return $o;
