base64_encode/base64_decode problem

[Angry Coder]

Hi,

Could you please tell me where is the error in the fallowing code:

$name = "Angry Coder";

$name = base64_encode ("echo $name;");

echo $name;

echo "<br><br><br>";

eval (base64_decode ("ZWNobyBBbmdyeSBDb2Rlcjs=")); 

Thanks

$name = base64_encode ("echo $name;"); 

should be:

$name = base64_encode ($name);

Thanks. But i don't think that was the problem!

The fallowing code works fine:

$name = "AngryCoder";

$name = base64_encode ("echo $name;");

echo $name;

echo "<br><br><br>";

eval (base64_decode ("ZWNobyBBbmdyeUNvZGVyOw==")); 

I just removed the blank space from the variable $name!

I need to put spaces in my string!

instead of

$name = base64_encode ("echo $name;"); 

change the " to a ' (single insted of double).
havent tried it but since when doing something like this:

$name="Shanor"; 

and then

echo "hello $name"; 

what u get is
hello Shanor
what u actually wanna get as i understand it from u'r explanation is not the value of $name but the dollar sign and the name word so that u'll be able to execute it in the future...
doint the following:

$name="Shanor"; 
echo 'hello $name'; 

will result in:
hello $name
therefore u should have the following code line:

$name = base64_encode ('echo $name;'); 

hope i made myself clear.

coder...pardon my ignorance, but what exactly is it you're trying to achieve with this code ?

shanor,
Thanks for your help, but please read the fallowing to know what i want to do :


redux,
I am coding a script -that's not free- and i don't want people who buy it remove the copyright lines!!!
... I know they can remove it. But it will be much difficult if i do it this way

[redux]

ok, so you want to encode the "echo my copyright notice" bit and then have the decoded bit executed...right...but what stops people from just removing the eval() ? ok, inexperience users might not make a direct connection between an eval and a copyright notice appearing, but through trial and error they will.
also, if i personally saw this, i would damn sure want to know first thing what the decoded thing is before i let eval run lose on my server...ok, maybe paranoid, but that's me, eh ?
so...like the idea, but i think it's not worth it really...imho, of course

[redux]

on a related note: maybe it's worth looking at zend encoder. ok, maybe a bit pricey, but i don't know what kind of price you're asking for your script...

[shanor]

i guessed that, i saw it once in one of the code exchange sites...
but trully, just as redux said, the first thing i did was to decode it and analize the code (in that code not just the copyrigth was encrypted but the entire 200 rows were encrypted).
plz do tell me if what i wrote priviously worked?
Shanor.

[Angry Coder]

no programmers will not be able to decode it! believe me!
Some people can not even edit the config file!!!

+

The code of my script is complicated enough!

I gonna put some IMPORTANT variables in the encrypted code, so if (he) remove the copyright notice the script will be destroyed

shanor,
no, it didn't works.
