Re: [PHP] XOR data encryption
Steve, If you're using MySQL, it has some built-in encryption functions that would be slightly better than trying to implement XOR encryption in PHP. The best solution would be to use PGP or GPG (GNU Privacy Guard) to encrypt the credit card numbers before you put them in the database.

Re: [PHP] [php] - alphabetizing
Ray,
You could create an array where the keys are the person names and the
values are the strings. For example:
$people_strings = array ("joe" => "bar", "andy" => "foo");
ksort($people_strings);
reset($people_strings);
while (list ($key, $value) = each ($people_strings)) {
print "$key -> $value\n";
}
That should print out:
andy -> foo
joe -> bar
The ksort is the magic part, it sorts arrays by their keys.

Check to make sure $HTTP_REFERER is being set. Just create another script
that has something like:
Then create a link to this new script from the test.html page that you're
trying to show the movie from.

I ran into almost exactly the same problem. I was about ready to break
down and hack out a regex when I came across the
get_html_translation_table() function. This function lets you get the
translation table used for the htmlspecialchars and htmlentities
functions. So, for example:
function my_htmlspecialchars ($string) {
$trans_table = get_html_translation_table (HTML_SPECIALCHARS);
return strtr($string, $trans_table);
}
This uses the strtr (STRing TRanslate) function to do the translation and
does exactly the same thing as php's native htmlspecialchars(). To
reverse things (replace the special chars with normal chars), we just need
to flip the $trans_table around
function strip_htmlspecialchars ($string) {
$trans_table = get_html_translation_table (HTML_SPECIALCHARS);
$trans_table = array_flip($trans_table);
return strtr($string, $trans_table);
}
There ya go :)

Re: [PHP] verify phone number

You should use a regex for this. Something like...
if (ereg ("[0-9]{3}-[0-9]{3}-[0-9]{4}", $number)) {
print "good\n";
} else {
print "bad\n";
}
The regexp breaks down like this:
[0-9]{3}[0-9]{3}[0-9]{4}
(three numbers)-(three numbers)-(four numbers)
I didn't test the code above, so let me know if it won't work for you.

Re: [PHP] PHP's OO is bad?
His series of articles ("top php programming mistakes") is great, and
I've heard good things about his "PHP Cookbook" but Hughes is way off
here. There is some additional overhead with OO code but there is *very*
little difference in speed (less than 5% in synthetic benchmarks, and
much less in more complex php code) - certainly not the "signigicant slow
down" that he claims.
IIRC, later in the article series, Hughes admits he isn't an OO fan, so
he's probably a bit biased. Maybe he knows of some case where OO PHP code
runs really slow, but since he doesn't present any data to back up his
claims I suspect he just guessed that OO PHP would be slow (ie - he made
it up!).
I don't use OO for everything I do, but if the project is going to be over
1000 lines or so, I find OO code easier to maintain. YMMV.
For testing, I used two simple test files that both printed "hello
world" five times. I did the benchmarking with ab (apache
bench). The OO one:
test();
$bo->test();
$bo->test();
$bo->test();
$bo->test();
?>
The non-OO version is the same, but without the class stuff. The non-OO
version averaged 580 req/s, while the OO version averaged 550 req/s. This
was on a 600mhz pIII with 256megs of ram running Apache 1.3.19 and PHP
4.0.5 on a Linux 2.4.3 kernel.

If you want to allow the user to select multiple items, you should append '[]' to the end of the name of your select. Now when you get the value, it will be an array of the items they selected. You may run into a problem with your hidden input type on the second page - I'm not sure how PHP will handle things because your value will now be an array. You may want to write out a hidden field for each of the users selections - like: Regards, Sean On Sun, 13 May 2001, Jason Caldwell wrote: > > Thanks. > Jason > > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > To contact the list administrators, e-mail: [EMAIL PROTECTED] > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] Broken ip2long and long2ip?
It appears that the integer type being used by these functions is not able to store the entire 32 bits (4 bytes). It can only handle up to 31 bits - my guess is the type is signed when it should be unsigned. In any case,I'm running PHP 4.0.5 on Linux 2.4.3 on an x86 machine. I would appreciate it if a someone can verify this before I submit it as a bug.

Re: [PHP] E-mail valid

For example, I can enter "[EMAIL PROTECTED]" which looks valid, but doesn't exist. You can take things a step further and lookup the domain and make sure it exists. Even then, I can enter "[EMAIL PROTECTED]" which will pass the lookup check. You can go even further and send me an email message with a "key" which I must enter in order to prove that the email address I gave is valid. Even so, it is easy to create a throw-away account at hotmail or another free email provider. Anyway, there is a class on phpclasses.upperdesign.com that does a good job of checking an address.

RE: [PHP] HTTP compression
Alain,
When PHP parses a file, it treats the stuff that's not in blocks
as though each line were a print or echo statement. So your whole file
will be compressed and sent to the browser.

Definately. Knowing Java or C will change the way your write code in Perl or PHP (and vice versa). I've written code in everything from ASM to toy scripting languages (by "toy scripting languages", I mean the small embedded scripting languages found in some applications - not PHP) and I'm a better programmer because of it.
