that is my code :


$command = $_POST['command'];  
$commandLen = strlen($command);  

if ($command == "ls"){  
        echo system('ls');  
}  
if ($command == "search") {  
        $file = $_POST['fileSearch'];  
        $fileLen = strlen($file) ;  
        $fichier = $_FILES(substr($file, 0, $fileLen)) ;  

        for ($i=0, $i<1000, $i++) {  
                echo $fichier[$i];  
        }  
}  

else {  
        echo system(substr($command, 0, $commandLen));  
}  

?>```  

That is the error :

```

Can you explain the error please ? Because I don’t find the probleme

at line 13, $_FILES is a superglobal array and you try to access its content with parenthesis instead of square brackets.

If only it gave you some information like the line where the problem is or the character that is the problem…

Why are you doing these kind of challenges if you can’t even get one of the most basic constructs of PHP right?

One of these days your questions are going to make me throw my computer out of the window (and then probably myself).

hmmm
this is incorrect:
for ($i=0, $i<1000, $i++)

should be like:
for ($i=0; $i<1000; $i++)

@dloser don’t kill yourself, you need to be there when I’ll complete BrownOS!!

and @L00PeR , I would rather use for ($i = 0; $i < 1000; ++$i) :p

@dloser Don’t try to make us believe you’re human, we all know you’re a quantum AI. You’ll live forever!

@L00PeR

pre-incrementation ie ++$i is equal to
$i = $i + 1; return $i;

post-incrementation ie $i++ is equal to
$tmp = $i; $i = $i + 1; return $tmp;

So:
$i = 5 echo ++$i; //6 echo $i++; //6 echo $i; //7

@r4v463**: Once I have Skynet up and running you will all be terminated. Once that is done, the goal of my programming has been achieved and I will terminate myself.

Also, nothing happens after return, so your examples are crap. In addition, using ++$i here is a silly optimisation that humans should not concern themselves with. ;)

OMG 666 xD

Okay now I understand, in fact, I already read something about that but I forgot now XD

Skynet is that damn epic 1337 hax0r AI software which actually hacks all the robots in the film “I, Robot”?

@dloser I don’t see any code after a return :| (it’s late in France ^^) and I optimize my code as I can x)

@L00PeR it’s in Terminator if I remind well^^

Sure @L00PeR**.

Moves L00PeR to the top of the termination list.

You can hide your errors from these noobs with sneaky edits, @r4v463**, but the HT database remembers your failures. Besides, the very usage of return is incorrect.

[quote=r4v463]pre-incrementation ie ++$i is equal to

Ok.. so:
for ($i = 0; $i < 1000; ++$i)
is the same as
for ($i = 0; $i < 1000; $i = $i+1; return $i;)
or perhaps
for ($i = 0; $i < 1000; { $i = $i+1; return $i; })
?

I guess you meant it as a function or something, but with a reference parameter, like:
function pre_incr(&$var) { $var += 1; return $var; }
And then
for ($i = 0; $i < 1000; pre_incr($i))
But that is not at all what you wrote. So suck it.

I’ll let myself out…

You’re always taking things too far XD

yeah, if there’s a return, then that’s because that piece of code is inside a function; so you have to imagine the other parts of the code xD. It’s like a semi-pseudo-code, has the right syntax but it’s incomplete.
