theres issues with this, should be....

if ( $community == 'Invision Power Board' )

{

  $you = "Cool";

} else {

  $you = "n00b";

}

Either way works. Of course, it could also be if ( $you == $cool ) and refer to IPB.

of course in an ideal world it'd be:

if ( $community = 'Invision Power Board' )

{

  $you = "Cool";

} else {

  $you = "n00b";

}

Very good coder. :lol: ;)

if ( $community == 'Invision Power Board' )

*cough cough*

obviously i'm faced with newbs here (yea i said it :P). Idea was to say that everyones community always is ipb, hence "in an ideal world" :P.

But the syntax...

What about it? It looks fine to me as far as PHP syntax is concerned.

if statements require a double equal. so if ($wolifie = "awesome") in incorrect. it should be if ($wolifie == "awesome")

You can do a single = in there.

It would only change how it works (ie wouldn't be comparing the value, but rather setting it and on success the condition would be true).

So in a perfect world, $community would always be set to Invision Power Board, so you wouldn't need to compare it, only set it.

Yeah, you still don't require a double == in there, a single = works fine. Try it some day.

$var = 'hello;

echo $var; // hello


if( $var = 'goodbye' )

{

echo $var; //goodbye

}

{

}

how come every manual everywhere uses two?

[Lewis P]

Honestly, I don't know. It's probably because the chance of you needing something to evaluate to TRUE is small, and that it's not really needed.

Checked php.net though?

[Wolfie]

In most instances, you would be doing something like

if ( $imagesize = getimagesize( $filename ) )

{

  (code to parse)

}

So long as there's no error and $imagesize is filled with data, then the condition is true. Take a look at this code: http://php.net/manual/en/function.fopen.php

    if(($fh = fopen($rssFile,'w')) === FALSE){

        die('Failed to open file for writing!');

    }

It's setting $fh to be the value of the file handler and if it fails (FALSE), then it executes.

Now I do agree that a single = is pragmatically correct but I fail to see the point of doing such a thing, because the else part of the if statement will never be executed unless there is a mysterious case where $community = 'Invision Power Board' would evaluate to false. <_<

pssst, it's this thing called a joke...

which part?

[Wolfie]

if ( $community = 'Invision Power Board' )

{

  $you = "Cool";

} else {

  $you = "n00b";

}

[Enkidu]

you call that a joke? <_<

[Wolfie]

As a matter of fact, Mister Data, it's something that requires a sense of humor to get. <_<

And yet another topic is totally derailed.

And yet another topic is totally derailed.

-1 for "My other account is Wolfie"

[Wolfie]

I found a good design...

[Lakai]

wow talk about going way off topic..

[Mark]

I think Jaggi's joke went over a lot of heads :P

They're different things. A single = is of course an assignment operator, a double (or triple) = is a comparison operator.

This is completely valid code:

if ( $foo = bar() ) { // Is executed if bar() returns true. $foo is now true. } else { // Is executed if bar() returns false. $foo is now false. }

On the other hand:

if ( $foo == bar() ) { // Is executed if bar() returns the same value as whatever $foo is } else { // Is executed if bar() returns a different value as whatever $foo is }
