I think you have HTML and PHP mixed up. You cannot use the an ID more
than once in an HTML page, class yes. For variables, you do say:
<?php
if(isset($_GET['year']))
{$year = $_GET['year'];
//do some testing to make sure the value is what you want}
else
{$year = 1960;}
echo "<p>The initial year is ".$year.".</p>";
echo "<p>Loop 10 years:</p>";
for($i=0;$i<10;++$i)
{
echo "<p>The year is now ".$year+$i.".</p>";
}
?>

$_GET(variable) does not work. You need $_GET[variable].

Did you ever think about using the source, PHP.net?

The following might be slightly less confusing, and slightly more efficient:
<?php
$year = (isset($_GET['year'])) ? $_GET['year'] : 1960;
/* do some testing to make sure the value is what you want */
?>
<p>The initial year is <?php echo $year; ?>.</p>
<p>Loop 10 years:</p>
<?php
for ($i = $year, $maxYear = $year + 10;
$i < $maxYear;
++$i)
{
?><p>The year is now <?php echo $i; ?>.</p><?php
}
?>

There is nothing wrong with his newsreader. If you see broken quotes,
you need to check YOUR newsreader.

Which does not answer richard's question. But that's pretty normal for you.

Richard, you really need to get a good book on php. Trying to
haphazardly search the internet doesn't work well. And while php.net is
a good reference, I don't find it to be a good learning tool. Please
save yourself a lot of heartache and spend a few dollars for a good book
to help you learn.
As for your question - you're confusing '=' and '=='. There is a
difference.

In the year since Richard has been regularly posting, I would have
expected him to have at least run through http://www.w3schools.com/php/default.asp
and/or http://www.tizag.com/phpT/
and to have obtained a basic knowledge of the syntax of php.
Now either he has not had the intelligence to have searched for php
tutorials, or he has done them but has not had the intelligence to
understand anything he has done.
Either way, telling him to buy a book on php is a rather cruel way of
wasting his money.
I've suggested before that he and JRough should go into partnership.
They could have endless fun together hitting random keys and
pretending that they are programming.
I'm sorry if this seems rude, but it is fairly obvious that some
people simply do not have the aptitude for programming and I think it
far better to let them know this so that they can go off and try
something else.

I don't know, Paul. You may be right. I've had students in my classes
before who are completely lost even on simple non-language specific
pseudo-code examples. However, others have started out badly, and with
the right tools, have succeeded.
Personally, I don't think w3schools is all that great a learning tool.
It's ok for some stuff, but pretty shallow in their coverage of most
stuff. As for tizag.com - heck, I've never run into that one, either.
I'll have to take a look at it.
But it's obvious Richard is trying, and isn't going to give up. So if I
can point him in a direction which will help him better than newsgroups
do (usenet isn't good for everything!), I will.
And as for his problem - it's a common one I see all the time in my
classes, even from more experienced programmers, and one I make with
embarrassing regularity myself :)

Then whatever code you have at 'Assume here we change $year to be
"1961"' is, to use the appropriate technical term, fucked code, and you
need to fix it.
> Even if I use a second instance of $_GET().
1) You've already been told that $_GET is an array, not a function call,
and that you must use $_GET[some_fieldname_in_quotes] rather than
$_GET(some_random_text). If you can not absorb this simple bit of
information, you will never learn to code in php, so you should stop
trying now.
2) I don't see a first instance of a "$_GET['some_field_name']" or even
a richard_fucked "$_GET(something)" in the example code you offered, so
I have no idea what you mean when you say the problem occurs even if you
use a second instance of $_GET().

Since when do you care about the intelligence of anyone else?
He definitely wants to learn, otherwise he would not post a question here.

Spamming someone else's name is not very polite. Especially because this
person has no (direct) reference to this thread.

I dont think you ARE sorry.
If you really think he's not able to learn some programming, than you
could also simply ignore his messages, which saves you your 'valuable'
time, and saves some other people a lot of frustration.

I see broken quotes too, and I've disabled all forms of word wrap.

Actually I missed something here that's been picked up by Jerry.
$ cat testdick.php
<?php
if ($year="1961") echo $year . "\n";
?>
$ php5 testdick.php
1961
$
and
$ cat testdick2.php
<?php
$year = "1960";
echo $year . "\n";
$year = $year + 1;
echo $year . "\n";
if ($year=="1961") echo $year . "\n";
$year = "1961";
echo $year . "\n";
if ($year=="1961") echo $year . "\n";
?>
$ php5 testdick2.php
1960
1961
1961
1961
1961
$
So if you're not getting an output of 1961 where you expect it,
something else is fundamentally fucked.

I looked at the message source, and there's a newline before "ONCE!",
but no quote character after the newline. I'd call that broken quoting
myself.
Whether it was broken by the newsreader or some action of the poster is
moot - if the poster manually inserted the newline and didn't add a
quote character it was user action, not a broken newsreader, that led to
the broken quoting.

Jerry, I bought the PHP 5 bible ok? Like most of these damn things, it is
so filled with gobly gook only a trained technician could understand.
Several times he spends 10 pages on crap that has no relation to anything
any person programming needs to know.
And for you captain pukehead, I constantly read through php.net, tizag, and
a host of others.

Chances are that it was the Adrienne's newsreader which missed completing
the quote character when line-breaking the quotation. Hence my (implicit)
advice that they check its settings or get a better one.

Nobody said it was. However, your posting slightly too long a line (73
characters) for Adrienne's settings (perhaps 72 characters max.) might have
contributed to this problem.

And there is my point. If you have constantly read this stuff and you
still do not understand the basic syntax of php, then there really is
no hope for you.
But since I note that you have started calling me names that I would
expect to hear from kindergarten age children, maybe the problem is
simply that you haven't grown up.

Actually, Richard, I've seen that book. It's a pretty decent
programming book. There is nothing in it a programmer shouldn't know.
As for having to be a "trained technician" - I haven't seen anything in
there requiring such expertise. It does, however, require a logical mind
and understanding of some very basic concepts - concepts every
successful programmer must know (like what is a "byte"?).
I'm sorry you think it's such a poor book - but you can't get a whole
lot better.

Not according to Richard. He says that it is php.net that is wrong. He
can type whatever he likes. If the manual doesn't say that what he
typed is correct, it is the manual's fault.

Bullshit. The flaw is in script-kiddie languages like VBScript that do not
differentiate between comparison and assignment operators except for the
expression context.

Took me over a day when I first tried to write assembler, to realise
that the (paper) manual had indented the code, but that the assembler
refused to accept any line beginning with white space and silently
ignored them.
I assumed from the manual, the white space was a necessary thing to
include...
This being 1982 or thereabouts, and the first micro anyone I knew had
ever seen, who could one ask?

BASIC is the flawed language, allowing '=' to mean SET TO and EQUALS
according to ambiguous context
Sadly PHP copied BASICS lack of explicit typing as well.

I don't want explicit typing. Let the language work for you.

Explicit typing has many advantages - like having fewer bugs because you
can't do something stupid like pass a string where you expect an
integer. It's a big reason why you won't see large programs written in
untyped languages.

The equal sign `=' has been used in mathematics since medieval times to
denote equality. To use `==' for equality and `=' for something else
(assignment) is not sensible.

All fine and dandy if you're programming in BASIC, but when
programming in PHP you'll either do it as PHP requires or you'll not
get the result you expect. Sensible or not that's the way it is. Your
choice.

Not really. As in various programming languages dictate, usage and display
can be quite different.
In BASIC and simpler low level languages, we say <>, meaning "not equal"
while in the higher level languages we say, !=.

The symbols `/=' and `#' are also used in some high-level languages. It
is unfortunate that the not-equal-to sign is neither on a standard
keyboard nor in the 7-bit ASCII table. As a general guideline, however,
I don't think language designers should redefine the meaning of well
known symbols from mathematics. Or why not let `+' be the
increment-by-one operator and `++' denote addition? Why not? After all,
as Jerry Stuckle mentioned, programming is not mathematics.

I guess I am not lazy enough and prefer the language to do exactly what
I tell it.
