the function _get_browser() by fotos at uop dot gr has a few errors..well at least i had to change it to get it to work for me.
so...
$info[browser] = $parent;
$info[version] = $version;
becomes
$info['browser'] = $parent;
$info['version'] = $version;
and i use...
$browser = _get_browser();
if ($browser['browser'] == "MSIE").....
get_browser
Description
mixed get_browser ( [string user_agent [, bool return_array]] )get_browser() attempts to determine the capabilities of the user's browser. This is done by looking up the browser's information in the browscap.ini file.
By default, the value of $_SERVER['HTTP_USER_AGENT'] is used; however, you can alter this (i.e., look up another browser's info) by passing the optional user_agent parameter to get_browser(). You can bypass user_agent parameter with NULL value.
The information is returned in an object, which will contain various data elements representing, for instance, the browser's major and minor version numbers and ID string; TRUE/FALSE values for features such as frames, JavaScript, and cookies; and so forth.
As of PHP 4.3.2, if the optional parameter return_array is TRUE, this function will return an array instead of an object.
The cookies value simply means that the browser itself is capable of accepting cookies and does not mean the user has enabled the browser to accept cookies or not. The only way to test if cookies are accepted is to set one with setcookie(), reload, and check for the value.
注: 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.

Small comment regarding fotos at uop dot gr
the line:
$version = substr($_SERVER['HTTP_USER_AGENT'], $f, 5);
needs to be:
$version = substr($_SERVER['HTTP_USER_AGENT'], $f, 6);
for Firefox incremental updates to show up.

Regarding the code by steve (in Feb) and somewhat corrected by matt there is another ugly bug laying around:
Opera when set to report as IE returns the following header:
"Mozilla/4.0 (compatible; MSIE 6.0; Mac_PowerPC Mac OS X; en) Opera 8.5"
Well in the code given the last matching $browser in the array wins, and in this case the code reports "Mozilla" which is totally unexpected!
But Safari gives:
"Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/412.7 (KHTML, like Gecko) Safari/412.5"
The solution I can think of is to first search for more specific browsers and then for more generic (also seems more reasonable). If something matches then we are done. But probably this is not a catch all solution, but a good starting point.
So the code becomes:
<?php
function _get_browser()
{
$browser = array ( //reversed array
"OPERA",
"MSIE", // parent
"NETSCAPE",
"FIREFOX",
"SAFARI",
"KONQUEROR",
"MOZILLA" // parent
);
$info[browser] = "OTHER";
foreach ($browser as $parent)
{
if ( ($s = strpos(strtoupper($_SERVER['HTTP_USER_AGENT']), $parent)) !== FALSE )
{
$f = $s + strlen($parent);
$version = substr($_SERVER['HTTP_USER_AGENT'], $f, 5);
$version = preg_replace('/[^0-9,.]/','',$version);
$info[browser] = $parent;
$info[version] = $version;
break; // first match wins
}
}
return $info;
}
?>

This is a fix for a bug in the code left by steve (in Feb). Basically, if the search for the browser type was at the beginning of the 'HTTP_USER_AGENT' (ie. the first character) then strpos returns 0 causing, the code to drop out incorrectly. I also trimmed the code to make it more efficient.
function _get_browser()
{
$browser = array (
"MSIE", // parent
"OPERA",
"MOZILLA", // parent
"NETSCAPE",
"FIREFOX",
"SAFARI"
);
$info[browser] = "OTHER";
foreach ($browser as $parent)
{
if ( ($s = strpos(strtoupper($_SERVER['HTTP_USER_AGENT']), $parent)) !== FALSE )
{
$f = $s + strlen($parent);
$version = substr($_SERVER['HTTP_USER_AGENT'], $f, 5);
$version = preg_replace('/[^0-9,.]/','',$version);
$info[browser] = $parent;
$info[version] = $version;
}
}
return $info;

Here is what we do to fix the parsing error messages for php_browscap.ini downloaded from Gary's website.
<?php
// fix the browsecap.ini for php
$v= file_get_contents('php_browscap.ini');
$v= preg_replace("/\r/","",$v);
$v= preg_replace('/="(.*)"/i','=\\1',$v);
$v= preg_replace("/platform=(.*)/i","platform=\"\\1\"",$v);
$v= preg_replace("/parent=(.*)/i","parent=\"\\1\"",$v);
$v= preg_replace("/minorver=(.*)/i","minorver=\"\\1\"",$v);
$v= preg_replace("/majorver=(.*)/i","majorver=\"\\1\"",$v);
$v= preg_replace("/version=(.*)/i","version=\"\\1\"",$v);
$v= preg_replace("/browser=(.*)/i","browser=\"\\1\"",$v);
$v= str_replace("[*]","*",$v);

This might be useful for some until the Gary Keith updates his library. I added this to my browscap.ini to detect the latest Safari update for Panther, and the new Safari in Tiger:
;;; Added manually 05.04.19 for Safari 1.3
[Mozilla/5.0 (Macintosh; U; PPC Mac OS X; *) AppleWebKit/* (*) Safari/31?]
parent=Safari
version=1.3
majorver=1
minorver=3
;;; Added manually 05.04.26 for Safari 2.0 (Shipped with Tiger)
[Mozilla/5.0 (Macintosh; U; PPC Mac OS X; *) AppleWebKit/* (*) Safari/41?]
parent=Safari
version=2.0
majorver=2
minorver=0
Note: Full $_SERVER['HTTP_USER_AGENT'] for Safari 2 (Tiger) is
Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/412 (KHTML, like Gecko) Safari/412
(Disclaimer: I do not know if the entries above conform to whatever syntax standard Gary uses in his file, but it works fine for me).

To :: TomkOx ::
It's actually better to use strpos(). You need to use === or !== rather than == or != to check the return value though, otherwise you'll get 0 which equates to false when the string is found at position 0.
For example:
<?php
if(strpos($haystack, $needle) !== false) {
/* String was found */
} else {
/* String wasn't found */
}
?>
That'll work for any position, even 0.

It is not good to use function: strpos() in detecting browser or OS by HTTP_USER_AGENT. Better is to use function strstr() becouse some strings returned by HTTP_USER_AGENT have 'needed information' at 1st (0) position of the string. Function strpos() 'will not find' for eg. signature of Opera on OSX. I think it's better to use like this (example):
<?
// ...
Class SomeDetectoriumClass {
// ...
// here starts this method (function):
function aboutNetGuest() {
$curos=strtolower($_SERVER['HTTP_USER_AGENT']);
$uip=$_SERVER['REMOTE_ADDR'];
$uht=gethostbyaddr($_SERVER['REMOTE_ADDR']);
if (strstr($curos,"mac")) {
$uos="MacOS";
} else if (strstr($curos,"linux")) {
$uos="Linux";
} else if (strstr($curos,"win")) {
$uos="Windows";
} else if (strstr($curos,"bsd")) {
$uos="BSD";
} else if (strstr($curos,"qnx")) {
$uos="QNX";
} else if (strstr($curos,"sun")) {
$uos="SunOS";
} else if (strstr($curos,"solaris")) {
$uos="Solaris";
} else if (strstr($curos,"irix")) {
$uos="IRIX";
} else if (strstr($curos,"aix")) {

} else if (strstr($curos,"unix")) {

} else if (strstr($curos,"amiga")) {
$uos="Amiga";
} else if (strstr($curos,"os/2")) {
$uos="OS/2";
} else if (strstr($curos,"beos")) {
$uos="BeOS";
} else { $uos="[?]EgzoticalOS";
}
if (strstr($curos,"gecko")) {
if (strstr($curos,"safari")) {
$bos="Safari";
} else if (strstr($curos,"camino")) {
$bos="Camino";
} else if (strstr($curos,"firefox")) {
$bos="Firefox";
} else if (strstr($curos,"netscape")) {

Another PHP browser detection script that might be of use to you is here:
http://tech.ratmachines.com/downloads/php_browser_detection.php
This script uses a fairly different logic than get_browser, and doesn't worry about things like table/frame ability. This script was being used by mozdev to id Mozilla versions, since it specializes in that kind of specialized id. It also has unix/linux version os iding.

Be aware of the fact that this function shows what a specific browser might be able to show, but NOT what the user has turned on/off.
So maybe this function tells you that the browser is abel to to javascript even when javascript is turned off by the user.

PHP is sensitive to characters outside the range [ A-Za-z0-9_] as values in .ini files. For example
browser=Opera (Bork Version)
causes PHP to complain, as it doesn't like the parentheses.
If you place quotation marks around the values for all keys in the browscap.ini file, you'll save yourself parsing problems. Do this in eg vi with %s/=\(.*\)/="\1"/g
You could of course use PHP itself to fixup the file. Exercise left to the reader.

Please keep in mind that you should somehow (for example in session) cache the required results of get_browser() because it really slows thinks down.
We have experienced that without querying for browser data our scripts would run 120-130% faster. the explanation is that over 200kb long file (browscap.ini) has to be loaded and parsed everytime someone access any page (we need browser results on all pages).
So keep results in session and expect a performance boost.

Here's a quick way to test for a Netscape browser. IE and Konqueror and several others call themselves "Mozilla", but they always qualify it with the word "compatible."
$isns = stristr($HTTP_USER_AGENT, "Mozilla") && (!(stristr($HTTP_USER_AGENT, "compatible")));

The only way browscap examines the target browser is through the HTTP_USER_AGENT so there is no way you can determine installed plug-ins. The only way to do that is through client-side JavaScripts.

the example is great if you just want to spit out all that stuff, but i highly doubt anybody really wants to do that. To use the get_browser object in a conditional statement, do something like this:
$ua = get_browser ();
if ( ( $ua->browser == "Netscape" ) && ( $ua->version < 5 ) ) {
// code to fix the page for netscape :)
}
