You need to put the name of the GET data you want to read in brackets. 
Like so.


$_GET['SERVER_NAME'];

or

$l_url2 = ".".$_GET['SERVER_NAME'];

Maybe I missed something here, but aren't the cc's held by the

Considering their is no validation of the credit card number, you
could just use a random string of numbers starting with 99.

According to 
http://en.wikipedia.org/wiki/List_of_Bank_Identification_Numbers#References,
nothing starts with 99.

Can you come up with a phony CC number that fails the

  binhex($cc_encrypt)
  binhex($row['encrypt_iv']))

Why are you using text fields for storing binary data?

Ah, it was my mistake, I misread the spec. It's only the TLD that must
not be completely numeric, so that check can be taken out of the code I
gave earlier.

Probably a browser issue.  The above works fine with e.g. FF3.6 amd
Konqueror 3.5.

Perhaps not the correct expression, but most non-English languages have
their own alphabets, and despite some countries sharing a language,
what they allow for domain name registration isn't always the same
(ref. Michelle Konzacks earlier posting).
For instance, while 'ï' is used in Dutch, English, and French (I
believe), it is not used in Danish, so it is not allowed in Danish
domain names.  

Here is the list of characters accepted by the German registrar: 

http://www.denic.de/de/domains/internationalized-domain-names/idn-liste.html

The Swiss registrar:

https://www.nic.ch/reg/wcmPage.action?res=/reg/guest/faqs/idn.jsp&plain&lid=de

Austrian registrar:

http://www.nic.at/fileadmin/www.nic.at/documents/idn/idn_at_tld_de.txt

Danish registrar:

https://www.dk-hostmaster.dk/selvbetjening/koeb-dk-domaenenavn/tegnsaet-for-domaenenavne/
(quite limited: a-z, 0-9, hyphen, æ, ø, å, ö, ä, ü, é)

> Are the Greek letters Sigma, Delta, Pi part of this "National

No, only the Greek alphabet which probably is used in Greece and Cyprus
only.

Not in my experience.  The various national/European registrars usually
have very strict regulations, and any domain registrar offering his or
her services to the public had better understand them.

National alphabet? Never heard of it -- what Nation?

Are the Greek letters Sigma, Delta, Pi part of 
this "National alphabet"? While they are common 
in our English language, I don't think they are 
not included.


In addition, many registrars are clueless about 
IDNS, Char Sets, and what is legal and not. Plus, 
the are many differences between different TLD 
registrars. For example, the TLD COM can have 
single characters whereas the ORG will not allow 
single characters regardless of language 
(including ASCII).


The IDNS is still in a state of flux.

Do you know, that there are MANY domains with numbers only?

Like <163.com> or <126.net> which are legal names.

Oh I should mention that I block ANY mails from this two  domains  since
chinese spamers use it excessively.

on my Ubuntu box, I can copy and past the ˆ (square-root) character and
it displays properly in he address bar on google chome, but it
translates it back to the http://xn--19g.com and doesn't show anything
else (well... the page loads...LOL)

so did you register the xn--19q.com address knowing that it would
work/translate to ˆ.com (square-root) ?

Steve:

When I was associated with the IDNS WG (not a 
member), there came a time where the "powers that 
be" wanted to "try out" their solutions, namely 
PUNYCODE. As such, we were allowed to register 
IDNS domain names on a trial basis. The 
conditions of the trial were that we could 
register any IDNS we wanted (at $100 a pop) and 
if at anytime over the following year our names 
caused problems, then we would forfeit our names 
without compensation. In short, a $100 per-name 
bet!


At that time, I registered almost 30 names. 
Fortunately, all of my names passed and I was 
permitted to keep them. Unfortunately, all 
browser manufactures (except Safari) negated some 
of the work done by the IDNS WG and as a result 
PUNYCODE is shown instead of the actual 
characters intended.


I continue to hold on to my domain names because 
I believe that the PUNYCODE problem will be 
resolved someday and my single character domain 
names will be valuable. Please realize that 
single character ASCII characters are estimated 
to sell for over a million dollars each -- you 
may want to review this:


http://www.cbsnews.com/stories/2005/11/28/tech/main1080245.shtml

In any event, this is out of the main stream of 
PHP. However, it should just be noted that 
Unicode characters, which started this thread, 
are very involved and many software manufactures 
are not implementing solutions correctly. In 
contrast, the PHP community has provided numerous 
Multibyte String Functions (mb_) for dealing with 
Unicode. So, our PHP applications can correctly 
deal with what Unicode provides that are far 
exceed simple ASCII.

tedd

on my Ubuntu box, I can copy and past the √ (square-root) character and
it displays properly in he address bar on google chome, but it
translates it back to the http://xn--19g.com and doesn't show anything
else (well... the page loads...LOL)

so did you register the xn--19q.com address knowing that it would
work/translate to √.com (square-root) ?

Donovan:

Yes, Safari shows ALL Unicode Code-Points (i.e.,

Here's a couple of examples:

http://xn--u2g.com

http://xn--w4h.com

Interesting enough, the above characters cannot 
be typed directly from a key-board, but are shown 
correctly by a Browser.


However as I said, these can only be seen 
correctly by the Safari browser. If you use IE, 
then the URL's will be shown as PUNYCODE -- M$ 
has a "better idea".


What I also find interesting is that there are no 
restrictions for using IDNS names in email 
addresses. However, even Apple's Mail program 
restricts these to standard ASCII.


IOW, an email address of t...@ˆ.com is perfectly 
legal (and will work), but no email application 
will allow it.

Daniel et al:

Translation of Unicode characters by various 
software programs is unpredictable -- this 
includes email applications.


While I can send/receive ˆ (square root) through 
my email program (Eudora) what your email program 
displays to you can be (as shown) something 
completely different. The mapping of the 
code-points (i.e., square-root) to what your 
program displays (much like a web site) depends 
upon how your email program works. If your email 
program has the correct Char Set and will map it 
to the what was actually received, then the 
character will be displayed correctly. If not, 
then things like –.com happen.


Unfortunately, this mapping problem has not been 
of great importance for most applications. As it 
is now, most applications work for English 
speaking people and that seems good enough, or so 
many manufactures think. However, as the "rest of 
the world" starts using applications (and logging 
on to the net) it will obviously become more 
advantageous for manufactures to make their 
software work correctly for other-than-English 
languages. Apple is doing that and last year the 
majority of their income came from overseas 
(i.e., other than USA).


The mapping of other than English characters was 
the problem addressed by the IDNS WG, where I 
added my minor contribution circa 2000. 
Unfortunately, homographic issues were not 
resolved by the WG. However, a solution was 
proposed (I entitled as the "Fruit-loop" 
solution) which was to color-code (flag) the 
characters in the address bar of a browser IF the 
URL contained a mixed Char Set. Unfortunately, 
that solution was not pursued and instead Browser 
manufactures choose to show raw PUNYCODE, which 
was never intended to be seen by the end users. A 
giant step backwards IMO.

tedd

^ is to the power of, not square root, which is √, which does translate
to Tedds domain

error in translation.

I get the same domain for:
seamonkey
firefox
googlechrome
safari

but yes, the actual square root character appears in safari only.

Thanks for the math lesson, professor, but I already knew that.  ;-P

My point is, and as you can see in the quoted text from my email,
that I don't know if it was a typo on Tedd's part or what, but ^.com
is what came through here.

You're talking about IDNs ?  The actual domain name is still US-ASCII,
only when you decode punycode do you get UTF8 characters.

Per Jessen, Zürich (10.1°C)



Unfortunately, you are correct.

It was never the intention of the IDNS WG for the 
end-user to see PUNYCODE, but rather that all 
IDNS be seen by the end-user as actual Unicode 
code points (Unicode characters). The only 
browser that currently supports this is Safari.


For example --

http://xn--19g.com

-- is square-root dot com. In all browsers except 
Safari, PUNYCODE is shown in the address bar, but 
in Safari it's shown as ˆ.com


The IDNS works, but for fear of homographic 
attacks IE (and other browsers) will not show the 
IDNS correctly.

FYI, if I swap out the guts with this snippet:

foreach ($key_vals as $k => $v)
{
$path = 'ini_array[\''.$heading.'\']';
$subsection = explode('.', $k);
foreach ($subsection as $ss) $path .= '[\''.$ss.'\']';
$path = '$'.$path.' = \''.$v.'\';';
eval($path); //it's not elegant but it works!
}

It works. Not sure if it's any better or worse than the other hack though.
I'd still like to know what is wrong with the initial version for future
reference.

Hi,

I have used this code to feed data to gpg and read back the encrypted
result, Im sure you can adapt it to your needs.

function Encrypt($data){

# http://www.theoslogic.com/scripts/php-gpg/

$gpg_command="/usr/bin/gpg $parameters";

$errLog = "/tmp/errors.log";

$dspecs = array(
0=>array("pipe", "r"),
1=>array("pipe", "w"),
2=>array("file", $errLog, "a")
);

$encrypted="";
$procdata="";

$gpgproc = proc_open($gpg_command, $dspecs, $pipes);

if (is_resource($gpgproc)) {
fwrite($pipes[0], $data);
fclose($pipes[0]);

while($procdata = fgets($pipes[1], 1024)) {
$encrypted .= $procdata;
}
fclose($pipes[1]);
}

return $encrypted;
}

It works really well.

Regards

Ian
