What I was getting at was not that Debian was hard to use, but harder to
install than ones like Suse or Ubuntu.
I understand what you mean about being forced into specific software
though. For some reason the company I work for was advised ages ago that
IIS, MSSQL and ColdFusion was the combination to use, and now we have a
load of legacy sites that we have to maintain. This combo is just not
good for websites, and to do anything useful with CF you have to buy
loads of addons. :(

I have to disagree here. Although it uses tables for layout, it can be
changed quite a bit by going into the code that makes up the pages. I
had to do this for a previous site I worked on which used OSCommerce. As
well as changing the whole design, I had to add loads of functionality
to it on the product display area. It took quite a while, as the system
is not intuitive, but it is possible. I do know what you mean about the
source code though, it took me a long time to get to grips with it in
the end!

Are you sure you can make following my original code work to play the
mp3 automatically in firefox or any other browsers?
<html>
<embed src="audio.mp3" autostart="1"></embed>
</html>
BTW, I also tried to change <object type="audio/x-mpeg" ....., did not
work either.

Whoa dude -- not only is putting width and height in a tag not good

It should be:
<html>
<embed src="audio.mp3" />
</html>
No, the autostart attribute is fine, but should be set to true.
<html>
<embed src="audio.mp3" autostart=true ></embed>
</html>
The above will work for Netscape -- but for other browser (i.e.,
IE's, Opera, el all) use:
<html>
<bgsound src="audio.mp3" ></bgsound>
</html>
Also you can add the attribute of "hidden=true" to both.

Well, this is weird. When I copied your text and tried it myself, the
error I got was:
Parse error: syntax error, unexpected T_STRING in /Users/ericgorr/
Sites/page1.php on line 9
Now, of course, there is nothing visibly wrong with line 9
($_SESSION['animal'] = 'cat';). But, when I had my text editor show
invisible characters, there were some on that line and line 10.
Do you have a text editor that can show invisible characters?
On the Mac, the one I really like (and is free) is TextWrangler
(http://www.barebones.com/products/textwrangler/ ) and has this
capability. This may be part of your problem. Once I got rid of the
invisible characters, the example worked without any problems.
Also, are you certain there are no spaces or anything (even invisible
characters) before <?php?
Whenever I've gotten a similar error in the past, that was nearly
always the problem. You are welcome to compress the text file and
send it to me directly so I can see exactly what it contains.
Since you're a PHP rookie, to sum it up: there can not be any output
before you start a session.
When PHP interprets a file (include or otherwise) it considers anything
before <?php as HTML, so it outputs it as HTML (newlines, spaces,
whatever). So if you have whitespace before the <?php, then the PHP
interpreter outputs it, thus the output before the session_start() error.

It's an easy mistake to make, not just reserved for rookies ;) I had a
similar problem streaming video to the browser, and found that for some
reason all the video files were larger than the original and wouldn't
play. Turned out (after some very strong words aimed in the general
direction of my laptop) that I'd included a header file which was
outputting some HTML!

The space is completely optional, but I don't think it has anything to
do with the form that the tag is using. By default, browser will just
hide any tags they don't understand. I think that what is happening is
that the < and > have been escaped out. Try viewing the source to the
output page. If you see <br/> then your CMS is escaping the
chevrons and interpreting them as literal text rather than code.

Your xss answer is moot. XSS attacks can (almost) just as easily be

No, because you can't click on a link that make a post. Maybe on

This is a slightly OT but along the same lines.
I've found that the main way that ISP's and large content hosts control
who can access their site and from where is by using BGP routing (Border
Gateway Protocol), and other advanced things that are beyond the control
of the majority of webserver admins.
It allows them to change the routing that information, which is for
example, how your ISPs servers know where to forward your data packet to
next.
However with some funky router, you can get 'magic' IP addresses, like
Akami and most ISP's DNS server have.
E.g, You will request to access data on a certain Akami IP address,
instead and taking >200ms to hit some server on the other side of the
world, and come back, it could go to a server sitting in your nearest
capital city in <50ms, which is great for video content, and AJAX calls.
The thing is, someone in another country could request the same data
from the same IP, and the request will automatically be sent to a
completely different server, most likely that of one in their capital
city (or at least the closest place that has an Akami server containing
the required info).
Above is just another example of how you can't purely rely on IP
addresses, although it is the easiest thing from a webservers PoV, and
usually right >90% of the time (as far as I am aware, although haven't
tested, nor have any good ways of testing besides Traceroute).

I used to have a demo of that, but my server
crashed and with it went the database.
It was one of those stupid things of having
everything backed up but the database.
Too bad, I had it running for a couple of years
gathering "correct" or "not correct" input from
visitors.
Just another of my lame attempts to do something of worth.

Hi,
Just started with object oriented programming and glad I have come across
it, just need a few things clearing up.
When I make a variable or method public, does this mean that it can be used
outside of classes, for instance in other classes or as well as
instantiating classes? So if I made it private, it wouldn't be able to be
instantiated or extended in other classes, am I right?
I have never added public when I am creating methods so I presume its
already set as default if you don't add it?
Hope you can understand my question.

yes, and the answer nearly always lies in trying it out, run this
(and if/when you hit a fatal error, comment the offending line and run it
again):
<?php
class Test

protected $b = "B";

class TestTwo
{

$t1 = new Test;
