This is not PHP related, but I'll point you in the right direction.
I have looked at your code and it is different to the source on the
page found online.
The line;
<option value='97' selected="selected">Japan</option> (Online version)
Is different to:
<option value='97' selected>Japan</option>

FireFox may be "remembering" whatever you last selected.
That's a browser "feature" you have to live with.
Move along, nothing to see here :-)

cast the value to a string when you pull it out if you want to use it that
way:
<?php
$xml =
<<<XML
<?xml version="1.0"?>
<request>
<customerID>3</customerID>
<appName>agenda</appName>
<ticketType>cticket_agenda_server</ticketType>
<ticketTypeID>1</ticketTypeID>
<platformID>1</platformID>
<ticketAction>addUsersToGroup</ticketAction>
</request>
XML;
$file = new SimpleXMLElement($xml);
$ticketTypeAsSimpleXmlElement = $file->ticketType;
$ticketTypeAsString = (string)$file->ticketType;
$ticketTypeAnalyzer = new ReflectionObject($ticketTypeAsSimpleXmlElement);
echo (string)$ticketTypeAnalyzer . PHP_EOL;
var_dump($ticketTypeAsString);
?>

Thanks! Problem fixed... But I think PHP must do the cast automatically.
I think it's a bug fixed in a further version than mine as I've read

no problem; but just fyi, its not a bug; the behavior is as expected per the
manual:
http://us3.php.net/manual/en/ref.simplexml.php
*Example#6 Comparing Elements and Attributes with Text*
To compare an element or attribute with a string or pass it into a function
that requires a string,
you must cast it to a string using *(string)*. Otherwise, PHP treats the
element as an object.
if you use an operation that casts implicitly, such as echo, you dont have
to cast yourself;
otherwise you do :)

Find Weitz's "The Regex Coach" (Linux and Windows) and install it and
play around.
You'll learn more in one day from the pretty color syntax highlighting
than reading the perl books/pages for months.

Except that once you start trying to integrate several large bodies of
code, you have NO IDEA what exceptions can be thrown, and even less
idea where they didn't get caught and handled properly.
Worse, many times the library[ies] you are integrating to an abysmal
job of doing anyting intelligent with the catch block, and you're
stuck with something even worse than set_error_handler.
try/catch works great for small/medium projects, or even large
well-documented projects perhaps, but as soon as you start trying to
integrate several projects...
Well, in MY experience, try/catch just ended up biting me in the butt...

Write your own inter-process language that sends out some kind of HTTP
response that tells your .net client to do whatever it is you want it
to do.
Or, possibly, have the PHP script open up a socket
http://php.net/sockets to the .net application, and send commands and
data identifying itself sufficiently to make your .net application do
what it's supposed to.

Shared Memory is not for the faint of heart, but you'll still need
some kind of back-n-forth to identify who's doing what, I think, so
you might as well send the data with that...
Though I guess you could have a sort of "global" shared memory and
keep a running list of "to do" on there for the .net and PHP apps to
manage...

The 160 byte limit is carrier/handset dependent, and goes as low as
140 for some Canadian carriers.
The cell phone companies are happy to provision you with a gateway
account, if you can prove you are not a cell-spammer and will pay them
money.
If not, you are at the mercy of free systems designed for casual
limited use by end users, and abusing that with a PHP script that
could send lots of messages would be a very Bad Idea -- They'll just
block you as soon as you get going.
The core gear is owned by the phone companies. They're not interested
in providing free spammer access wide open to the general public for
some reason...

I'm betting there is a PEAR module to write Word docs.
Or you could use COM objects, if you are running PHP on a Windows box

I never optimize code unless there's a problem with its performance...
Why one would tweak code endlessly to maximize performance when that's
not needed is beyond me...
But maybe I'm just a Luddite.

thats only true until poorly designed software cant be spread across
machines
due to a monolithic nature.
get an opcode cache and index the database; that will probly absolve any
noticeable
speed problems.

Well obviously you can always write horrible code but if you write code
that is easy to maintain it's usually not that kind of code.

thats pretty subjective; ive worked w/ plenty of 'easy to maintain' code
that could
only have hardware thrown at it by a load balancer. which i consider a real
mess.
even then the design of the load balancer will have to maintain request
forwarding
to particular hosts unless the code already supports or is given support for
session
storage in a common location all the webservers can address.
i personally am not a fan of the 'just throw hardware at it' adage, if it
can be called that.
i was recently at the d.c. php conference and heard a talk from a gentleman
on behalf
of yahoo. he says they are *very* picky about getting new hardware; yahoo
wants clear
rationale for the addition of any new hardware into the system. in short;
they advocate
writing solid code because it saves them money in the long run.
what i see happening when people throw hardware at their problem is that in
early stages
it works great. then further down the road the software is unable to be
easily spread to
multiple systems and then guess what; you end up spending man hours to do
something that
could have been done in the first place. another issue is randomly added
machines can be
hard to maintain because their roles are not clearly defined.
what im saying is adding hardware to a system is natural and relevant, but
ensure it is a
good decision by evaluating alternatives before arbitrarily 'throwing
hardware at the problem'.

Perhaps it is valid, when the database is up and running.
But if your DB was re-started for some reason, the link won't be there
while it's restarting will it?
You've GOT to write code to handle the $link being false instead of
marching blindly off the cliff.
You are not a lemming. :-)

FIRST LINES OF CODE:
<?php
function error_handler($code, $message, $file, $line, $context){
die("ERROR: $message ($code) in $file:$line");
}
set_error_handler('error_handler');
?>
Anywhere else in your code:
[examples]
$connection = mysql_connect(...) or trigger_error("No DB access.",
E_USER_ERROR);

incidentally, i was looking through Pear::Log today;
i stumbled upon this and thought id share:
/**
* Using debug_backtrace(), returns the file, line, and enclosing
function
* name of the source code context from which log() was invoked.
*
* @param int $depth The initial number of frames we should step
* back into the trace.
*
* @return array Array containing three strings: the filename, the
line,
* and the function name from which log() was called.
*
* @access private
* @since Log 1.9.4
*/
function _getBacktraceVars($depth)
{
/* Start by generating a backtrace from the current call (here). */
$backtrace = debug_backtrace();
/*
* If we were ultimately invoked by the composite handler, we need
to
* increase our depth one additional level to compensate.
*/
if (strcasecmp(@$backtrace[$depth+1]['class'], 'Log_composite') ==
0) {
$depth++;
}
/*
* We're interested in the frame which invoked the log() function,
so
* we need to walk back some number of frames into the backtrace.
The
* $depth parameter tells us where to start looking. We go one
step
* further back to find the name of the encapsulating function from
* which log() was called.
*/
$file = @$backtrace[$depth]['file'];
$line = @$backtrace[$depth]['line'];
$func = @$backtrace[$depth + 1]['function'];
/*
* However, if log() was called from one of our "shortcut"
functions,
* we're going to need to go back an additional step.
*/
if (in_array($func, array('emerg', 'alert', 'crit', 'err',
'warning',
'notice', 'info', 'debug'))) {
$file = @$backtrace[$depth + 1]['file'];
$line = @$backtrace[$depth + 1]['line'];
$func = @$backtrace[$depth + 2]['function'];
}
/*
* If we couldn't extract a function name (perhaps because we were
* executed from the "main" context), provide a default value.
*/
if (is_null($func)) {
$func = '(none)';
}
/* Return a 3-tuple containing (file, line, function). */
return array($file, $line, $func);

Hello I'm building a website with a search engine.
Do you think it is more usable if the search interface had a search
button? or do you think it will be more convenient to not have button to
let the users just push "enter" to search.
I would appreciate any comment regarding this, thanks.

Not exactly PHP related, however..
Having the button there is an indicator that the user can do something.
Even if they simply press return, the button lets them know something
can be done.

The one thing I have found in building websites is that you should
always create the site to the lowest IQ. Make it simple because there
are users out there that might not know that you can hit enter (or
return) to activate a search.
That's my 2 pents worth.
