#2565 — error message I don understand

Hello group,

I'm doing some php programming on my own webserver.

I get the error message: PHP Fatal error:  Can't use function return
value in write context in line 69

This is line 69:  if (mysqli_num_rows($sDBResultaat) = 1 )

Either I don see what I'm doing wrong or I interpret the message wrong.
Either way I don't understand, can somebody point me the right way?

Thanks in advance, schimanski.

You need to use the comparison operator (==) rather than the assignment 
operator (=).

Odd, since I said exactly the same thing, with added humour.

Hmmm, strange form of humour. Not my cup of ........
Maybe due to the fact that Englis (nor American) is not my mothertongue.

Natural posted 2 hours *after* Billy and, of course, we're supposed to
assume that he didn't see Billy's reply to spur him onto the same
solution but differently composed.  

In some programming languages, the "=" is not an assignment operator
when its context is within the conditional clause.  In others, it is an
assignment operator (followed by a Boolean test for true or false) and
is sometimes used as a cheat but usually for the right-side operand.  If
you had reversed the left- and right-side operands you wouldn't get an
error in all languages and instead might get an assignment that you
didn't expect along with an action by the 'if' that was unplanned.

Sometimes another pair of eyes will see your mistake.  Too often your
eyes see what your mind expects to see.  Bouncing between multiple
programming languages doesn't help, either.  Don't let Natural fool you:
this is a mistake common to ALL programmers and shows up often enough
that all of them recognize the mistake because it wasn't so long ago
since they made that same mistake.

Never mind, I learned something I didn't know and that is a win.

Well you got your answer, I had some fun, reminiscing about  the first 
uncertain steps we all take in programming,  and no harm was done, so a 
win win hopefully.

I remember many years ago I went back to sort out some issues in some C 
code..someone else had taken ober

" I see you don't like using the 'switch..case' statement, its all 
nested 'if then else' here'

"No, I like it. Then I wasn't sure of the syntax, and I was under heavy 
pressure to get this working, so I used what I was familiar with".

(I didn't want to tell her it was in fact the first commercial C code I 
had ever written).

You have to understand TNP.  He's not a programmer (nor even the 
engineer he portends to be).  He really doesn't understand a lot.

What he does is wait for someone else to answer, reword it into an 
insult (if he even understands the original response) then, when called 
on it, claim it's "humor".

It's unfortunate that we have to put up with his trolling.  But then he 
wouldn't want people to find out who he really is - which is why he 
tries to hide behind a 'nym.

Thanks for explaining. I'm relatively new to this newsgroup, so I have
to learn who is a troll and who is really doing a good job in helping.

Over time I'll learn to distinguish trolls from helpers.....

That's a nice way of saying  that you are a complete numpty and haven't 
yet learnt to distinguish between assignment:-)

SET a=b

and comparison:

IF a==b

You can thank your lucky stars that your interpreter is merely obscure 
in its error messages  - heck if you had posted this to comp.lang.php or 
something, you would have got an impenetrable answer from Stuckle AND 
abuse, too;-)

However, I am pretty sure that I did this a couple of times when I 
started programming, so I am only going to have a chuckle at your 
glorious innocence, that reminds me of long long ago when programming a 
computer was a new and very strange thing.

Since I learned to program in a fair amount of computer languages, the
difference between = and == doesn't get the attention it needed to have.

Nevertheless I am delighted with your typecasting of me as someone
who is just asking. I hope you, as The Natural Philosopher are that much
enlighted that you will forgive me my typo......

Next time when I'm busy to ask something in your language, try to answer
it in mine. That makes you a philosopher.

Thanks, Schimanski.

Consider:

<?php

function x()
  {
  return 5;
  }

x() = 1;

?>

although x() gives the value 5, it is not a variable that can be set, and 
so you can not assign (or write) a value (such as 1) to it.

The php error message is saying that you can't assign (or write) a value 
to a function call, or in other words, the return value of a function 
call is read_only data.

Thanks Dennis.

Good addition to the explanation of Billy.

In the end an oversimplified, wrong explanation.  It is a syntactical 
requirement, not a functional one:

  function x()
  {
    return array(23);
  }

  $a = x();

  $a[0] = 42;

  /* 
   * Array
   * (
   *   [0] => 42  
   * )
   */
  print_r($a);

You would be well-advised to post under your real name, as it is customary 
in Usenet.

fair point, if pedantic.

And have the Stuckle stalk you in real life?

I think not.
