Hello
Using
http://www.micro-active.com
I find that with IE9 the page is not centred when first visited.
Moving to another page and then back to index.php it is then centred?!
With the latest Firefox, Opera, Chrome and Safari for Windows the page
is centred from the start.
Plus, if I do a W3C HTML check I see that the doctype is not known. If
I remove the php at the top of the file then no errors found, so, what
is wrong with the php?
Thanks
Geoff

There is nothing wrong with the PHP - PHP is server-side, and the client
knows nothing about it. It's your HTML which is incorrect.
The html may or may not have been generated by PHP - but it's not a PHP
problem. Try alt.html to figure out what's wrong with your html.

A quick look at the source of the above page shows that you are
inserting a mess of JavaScript at the top of the page -- prior to the
doctype. That's a no-no.

PHP is only a tool to do stuff. That stuff can include things like
sending e-mail, creating thumbnail images or (as in your case)
generating HTML to be sent to the browser. But the browser doesn't know
or care about that: all it can see is the final product as it arrives
through the internet tubes.
What's a DOCTYPE? It's a tag that you can insert at the top of an HTML
document to tell the browser what HTML version you are using. The
browser uses that information to pick rules on how to render the page.
What happens if the browser cannot find a DOCTYPE? It assumes that the
HTML document is a very old one, from the early times of the web where
DOCTYPEs did not exist yet, and it tries to render the page in the same
way that browsers from the late 1990s would do.
So, what's your problem? This:
script type='text/javascript'
src='assets/javascripts/soundmanager2.js'></script>
<script type='text/javascript'
src='assets/javascripts/jquery-1.5.1.js'></script>
<script type='text/javascript'>
soundManager.debugMode = false;
soundManager.onready(function () {
/*soundManager.createSound('helloWorld', 'assets/audio-new/chord1.mp3');*/
soundManager.createSound('helloWorld',
'assets/audio-new/welcome-plus6.mp3');
soundManager.play('helloWorld');
});
</script>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=iso-8859-1">
There is no DOCTYPE *on top* of the document. Even if there was one, you
are not generating a valid HTML document. That means that the browser
cannot follow the well-established rules on how to display a page: it
needs to guess how to fix your document first. And that's the main
problem: there're infinity ways to break HTML so there're infinite ways
to fix it. You cannot predict how the browser will do it.

thanks for your comments.
I have added the doctype etc info to the php at the top of the page
and now the page is centred in IE9 and the other browsers and W3C HTML
checker finds no errors.
Seems OK?

You don't have a constant called firsttime so this should trigger a
notice. You should enable full error reporting when developing:
ini_set('display_errors', TRUE);
error_reporting(E_ALL);

I just ran your page by the validator again, and it still says it can't
find the doctype.
Errors found while checking this document as HTML 4.01 Transitional!
Result: 5 Errors, 5 warning(s)
Maybe it is because of the blank line before it. Maybe it is because of
the single-quote marks in your doctype. Remove the blank line in the
resultant HTML and copy/use this (with double-quotes):
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

I have tried a whole lot of variations using
http://www.micro-active.com/index-test.php
which has
<?php
session_start();
ini_set('display_errors', TRUE);
error_reporting(E_ALL);
setcookie("firsttime","no");
$firsttime = $_COOKIE[firsttime];
if (@$firsttime != "no") {
echo "
<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.01//EN' etc etc
but I cannot get it right - I do see the error message "undfined
constant etc".
I have tried defining it by having
var $firsttime;
var $firsttime = '';
etc etc
but need a little more help please!
Cheers

And I think I'll add this, which is still OT for a PHP group, but I see
it as important. In your CSS, you've assigned a font-size of 80% ...
that is below my aged eyes' ability. And you're using Verdana. Use 100%
for your base font, and drop the overly-large Verdana font.
body {
background-image: url(pattern.png) ;
font-size:80%; /* 62.5*/
font-family:verdana,helvetica,arial,sans-serif;
line-height:1;
/*behavior: url(csshover2.htc);*/
}
line-height: 1 is less than normal. You should drop that.
Was 62.5%?? Were you reading about the horrible Clagnut method?

I will take a look at the font sizes but just for the minute I have
gone back to
http://www.micro-active.com/index.php
which is seen by W3C HTML Checker as HTML 4.01 Strict and sees no
errors.
But if I add a line such as
error_reporting(E_ALL);
I then get loads of errors in the Checker.
Plus in the normal browser window I see "undefined constant firsttime"
line 5
see
http://www.micro-active.com/index2.php
?!

Do you even know what a constant is?
I suggest you have a look at this chapter in the PHP manual:
http://es.php.net/manual/en/langref.php
You absolutely need to read the complete chapter, but for your immediate
needs you can start with the "Strings" and "Arrays" sections.

Well, yeah. "errors" are not valid HTML!

> line 5
Follow Alvaro's advice about " constants " and such. Your page inserts
HTML *above* (preceding) the doctype about your errors, thus blowing the
validity of it. Look at the source!
> see
> http://www.micro-active.com/index2.php
Errors found while checking this document as HTML 4.01 Transitional!
Result: 22 Errors, 8 warning(s)
In your CSS, please don't change the font-size and boldness of links
when hovered. Doing so makes the text jump about. A color change should
be sufficient.

There is a problem with IE9 in that although the page is centred on
the first visit (using css), after going to another page and then
returning to the index.php file, the page is no longer centred and the
drop down menu no longer works!
This does not happen with other browsers.
Any ideas?

Any site which interferes with the music I currently have on my machine
will not receive a second visit from me. A lot of others feel the same.

Only if you want people to visit only once then leave.

Check your HTML after they've visited other pages. But this is NOT a
PHP problem.

OK! I am coming round to agreeing with you.

I looked at the html on returning to index.php and low and behold the
doctype info was missing! Once I added an "else" section to the php
which echoed the doctype code info on the return when the
$_SESSION["index_with_sound"] was set the page centred itself and the
drop down menu worked.
Interesting that browsers other than IE9 somehow still showed the
doctype code on return!?
