Basic... is there (still) such a thing?
if( $a==1 && $b==2) { // do some cool stuff }
If you use a single =, you'll actually set the value and it'll always
be true. the double == checks equality without changing the value.
Use || for OR.

You haven't been listening.
You have been told what is wrong with this at least twice in the last
two days. You are failing to absorb this essential and fundamental piece
of php.

php is not basic. You need to use the correct php syntax and constructs
to do things in php. When you learn the basic php syntaxes and
constructs, people may become more helpful.

You say you are familiar with the php.net website, yet you obviously
managed to miss pages referring to control structures, specifically the
use of if, and logical and comparison operators, despite the fact that
they can be found in the clearly labelled control structures and
operators sections of the clearly labelled language reference section of
the clearly labelled manual.
Therefore, for your next lesson, go to the php.net website, find the
manual pages that deal with:
Manual
Language Reference
Operators
Operator Precedence
Manual
Language Reference
Operators
Comparison Operators
Manual
Language Reference
Operators
Logical Operators
Manual
Language Reference
Control Structures
If
Once you have read those pages, you will either know the answer to the
questions that you have asked here, or, if you do not then know the
answers, will instead know that you have no aptitude whatsoever for
programming in php and should find another hobby, probably one that does
not involve computers.

Dennis,
What was the point of that? When I started with PHP, I was as
unfamiliar with the jargon and even how to follow the manual pages.
The guy asked a simple question, so either answer his question or stfu.

If my syntax is wrong then so is the coding at php.net.
From php.net's example:
<?php
if ($a > $b)
echo "a is bigger than b";
?>
Where I may use a single = operator in a post, it is only to show what I'm
after in the whole.
I understand that it is best to use double == operators in real life.

This guy has been posting these same questions for over a year now.
Just how long do you define "started with php". A year is long enough
to understand basic syntax. Also he has posted the same sorts of code
that will never run in php for the past 7 days, despite having loads
of people correct him.
Maybe when he has been working with php for 10 years, you will
consider that he has not "just started"???

Not "best" you idiot. In php = is an assignment operator and == is a
comparison one. They do completely different things.
php.net is not wrong, you are an idiot.

It's not better YOU THICK CUNT it's essential. You are now plonked as you

I can see your frustration... I hadn't realized that this guy hasn't
taken the time, or perhaps he's using this forum to build in bound
links to the site he referenced. Still, I'm not sure that flaming
really helps matters. My $0.02.

It is not "best". If you want to test for equality, you *must* use either ==
(equality of values) or === (equality of values and of types): (5 == "5") ==
true; (5 === "5") == false; (5 === 5) == true; ("5" = 5) will produce a
syntax error, since you can't assign to a literal value.
The example that you bring from php.net is Ok. Greater than is spelled >.But
equal is spelled == or ===. On the other hand, >> is the right shift
operator.
If you really want to learn, you should be humble enough to know where you
are mistaken, instead of trying to hold your position regardless of how
wrong you are.
Denis' post is the best advice that you can get at this point. Go RTFM.

That is not wrong. Why would you even suggest it?

You can't do that.

It is not "best" to use == when you want to compare; it is "required."

Once you get to know richard, you'll probably understand. Case in point,
in his reply to your doing his work by providing a correct answer to the
"and" question, was your effort acknowledged? No.
In one of the other threads ("initial value"), Evan Platt said 'I have
NEVER once seen him say "Thanks for your help."' richard continues in
that mode, as always.

Yet, I haven't seen anything on php.net where this is stated.

They may do, but certainly not in this case. In this case idiots
overlook the value of actually reading!

As has been pointed out by others, you are constantly accusing the
authors of web sites and books, of not doing their jobs correctly,
when the problem is that you simply do not possess the intelligence to
understand what they have written.
You have purchased an excellent book on php and yet you say that it if
full of stuff that you have to be a super technician to understand.
BULLSHIT. Lots of people by that book and if they were super
technicians, they would not need to.
Stop wasting your time and money. Take up a hobby that does not
require you to use your brain.

It's not a question of it being "best". If you don't, then it doesn't
fucking WORK!
Are you starting to understand now.
By the way, I agree with all comments made so far that imply you may not
have the aptitude for programming.

And this differs from:
<http://www.php.net/manual/en/language.operators.php>
precisely how? And don't say it's because you need an extra click to get
to each section either.

Another concept you need to learn is not presenting one problem while
your after something else. You'll get called on it every time. These
folks are trying to help, really they are. But you have to meet them
halfway.

And yet you would have us believe that you have looked at:
Manual
Language Reference
Operators
Comparison Operators
which lists all the valid comparison operators for php. Meanwhile, over on:
Manual
Language Reference
Operators
Assignment Operators
it clearly defines what is a valid php assignment operator.
And yet you can not find this information? The only possible reasons are:
a) that you're not looking for it;
b) that you're incapable of absorbing it when you read it;
c) that you're so lacking in comprehension of basic programming concepts
such as "operators", "control structures", "data types", "assignment"
and "comparison" that you lack the fundamental knowledge needed to
navigate any programming language reference in a meaningful fashion.
The information that you are seeking is present in a clearly identified
form on the website that you claim to be unable to be able to find it
on. Almost (I can think of one other exception) everyone else in this
newsgroup is capable of locating and correctly interpreting that
information without any help whatsoever, yet you insist that it can not
be found even after receiving clear and unambiguous pointers to specific
parts of the on line documentation.
This tells me a great deal about your abilities and mindset.
Specifically that I'd be wasting my time in trying to give you any
further assistance whatsoever.

Not quite. Quoted from http://php.net/language.operators.assignment (first
lines):
The basic assignment operator is "=". Your first inclination might be to
think of this as "equal to". Don't. It really means that the left operand
gets set to the value of the expression on the rights (that is, "gets set
to").
Feel free to read up on comparison operators as well:
http://php.net/language.operators.comparison

You've had one all along: www.php.net, as people have been telling you for
more than a year.
