Hi Ross,
I previously worked on this theme and the general feeling / feedback from
the mailing list was the following one :
- access to your login window, via HTTPS (SSL)
- hash you password (inspired by :
http://phpsec.org/articles/2005/password-hashing.html)
- when user is authenticated, you can authorize him to go further, therefore
use a session and store in session array ONLY his login. (as he is already
identified).
all the webpages should be accessible in HTTPS (with first check on
$_SERVER[HTTPS] != 'on')
HTH.

Where should I store the password/username can I just have it located in the pagehead? I would be careful about using any code from that site. The code presented in that tutorial does not escape variables before putting them into SQL queries. In addition it appears to be storing the MD5 of the password in a cookie. This leaves it open to offline dictionary attacks. The author falsly represents MD5 hashes as encryption. MD5 is not encryption, it's a checksum. By all means use it as an example, but please be aware that it is not particularly secure and could open your site to attacks. -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I didn't provide a link to support my claim, I provided a link to prove how easy it was to find statistics. That my 1% asstistic was wrong was not surprising; however, your claim is not quite right either since the value of 19.4% is a value for all disabilities, not just ones that benefit from visual issues. The actual number of visual disabilities I believe was around a third of the given number, so closer to 6.5%-- I would increase that a bit for mental disabilities that may make processing of information more difficult. That said, I live in Canada, our disability numbers are around 12% versus the US 19.4%. So, there is marked difference between countries. So to set the record straight, I wasn't claiming anything and neither of our asstistics were correct :) Cheers, Rob. -- .. | InterJinn Application Framework - http://www.interjinn.com | :: | An application and templating framework for PHP.

hi,
this one I can't figure out:
I have to assign value of an array to variable named after key of the
array several times in my project to , e.g. after I submit a form with
personal info I have
$_POST['name'] = 'john doe';
$_POST['address'] = '123 main st.';
$_POST['city'] = 'urbandale';
$_POST['zip'] = '12345';
$_POST['phone'] = '123-456-7980';
etc.
Then I assign value to the var name:
foreach ($_POST as $key = $value)
{
${$key} = $value;
}
and then validate submitted.
Are you sure you want to do this? You never know what a hacker inserts
to your POST data, so he could easily define variables inside your
script, especially when you're using more dangerous functions like
system().
I do validation after this step. :)
you should validate before this step, not after. let's say you have an
important variable called $system_setting
then someone sends you a POST with 'system_setting' in it. then you're
writing that POST value to your important variable with that foreach
stuff, and trying to validate after it - but your system_setting value
is corrupted still!

Zoltán Németh
Though, to avoid writing all over again the same lines (even it's only 3
lines) I was thinking to create a function something like:
function value2var($array, $print=0)
{
foreach ($_POST as $key = $value)
I think you should change above line to :
foreach ($array as $key = $value)
yup! it's print error. I meant $array.
{
${$key} = $value;
echo ($print ==1) ? $key.': '.$value.'br'; // to test
results and seeing array variables and values
}
}
value2var($_POST, 1);
but, I don't know how to get info from function back to script?!?!?
:-(
Uhm, it's not even possible when you don't know the keys i believe.
after 2 hours of testing and research I realized this too, but want to
be sure.
:-(

RE: [PHP] preg_replace and regular expressions.
In your regex, you have a greedy matcher, i.e. .* will match as much
as it can to satisfy its condition. I believe you can do .*? and it
will work, as .*? will match as little as it can to be satisfied.

Subject: [PHP] preg_replace and regular expressions.
Okay, so what I have is a BB code type of thing for a CMS, which I for
obvious reasons can't allow HTML.
Here's the snippet of my function:
function bbCode($str)
{
$db = new _Mysql;
$strOld = $str;
$strNew = $str;
$getRegexs = $db-query(SELECT `regex`,`replace`,`search` FROM
`_bb_codes`);
while ($getRegex = mysql_fetch_assoc($getRegexs))
{
$search = base64_decode($getRegex['search']);
$regex = base64_decode($getRegex['regex']);
$replace = base64_decode($getRegex['replace']);
if (preg_match($search,$strNew) == 1)
{
for ($i = 1; $i 20; $i++)
{
$strNew = $strOld;
$strNew = preg_replace($regex,$replace,$strNew);
if ($strNew == $strOld)
{
break;
}
else
{
$strOld = $strNew;
}
}
}
}
$return = $strNew;
return $return;
}
**
But, for something like this:
[quote][quote]Quote #2[/quote]Quote #1[/quote]No quote.
I'll get:
div class=quoteContainer
[quote]Quote #2[/quote]Quote #1/div
No quote.
Despite being in the loop.
Regex is: /\[quote\]((.*|\n)*)\[\/quote\]/
Replace is: div class=messageQuote$1/div
Both are stored base64 encoded in a database.
Any help / suggestions much appreciated.

And right there is your first mistake. The only time to not have E_NOTICE on
is when you're using legacy code that isn't E_NOTICE compliant and you don't
have the time to upgrade it to be compliant. Developing without E_NOTICE
means you're telling the computer it's OK, let me just randomly guess where
this bug or security hole or random typo is. *Bad* idea.
*Always* develop in the tightest, most restricted, most nit-picky setting you
can get, regardless of the language.
If you want your syntax to be a bit simpler, I frequently use helper functions
along these lines:
function http_get_int($var, $default=0) {
return isset($_GET[$var]) ? (int) $_GET[$var] : $default;
}
if (http_get_int('var') ==5) {
// Do stuff
}
Clean to read, easy defaults, (reasonably) type-safe, and E_NOTICE friendly.

If you are looking for
isset($_GET['var'])
to return true if the value exists, but may be null, you can always use
if (isset($_GET['var']) || is_null($_GET['var]))
Albeit, I'm unsure if this will generate a warning if $_GET['var']
doesn't exist for the is_null() call. And in this case, I believe it
would be appropriate to ignore that one warning.

But when I add an element like $dirs = array (filemtime($d) = $d) (sorry the previous one is incorrect, I misunderstood what you wanted...) so: $dirs[filemtime($d)] = $d; greets Zoltán Németh the previous ones are lost. I tried array_push but that doesn't seems to work, at least I always get syntax errors. Next try was array_merge(array (...)). So what next? O.

I've had imagecreatefromjpeg() eat memory up to almost 50x the size of the image before finally deciding it can't handle it and crapping out. That was *after* running it through getimagesize() with no problem at all. okay - good point - but in this case the OP is reading in an html template file, just a string of 20.7Kb, what could go wrong there? this is probably one issue... the template is an HTML template containing images like img src=http://www.brainguide.com/xxx/. How does PHP handle this stuff? I suppose that it is just a string and the image at the URL is not really read, or am I wrong? The newsletter does not have any attachements. Now you're not making any sense at all... Either your newsletter has the images in it, or it doesn't. Embedded images are different to images with a href. To embed images, you need to read them in to memory and attach them (much the same as a regular attachment). Referencing a href like that doesn't do anything, it's just part of the string. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] auto page generation
I'm building a website right now that will be a database of attractions in the Carolina and Virginia area. The idea is that attraction owners can submit data to the database and the database will automatically generate a page containing that information. What I'm trying to figure out is how to generate the pages automatically and have links to them added to the site. If someone could help me or point me in the direction of a book or web page that covers this I would really appreciate it.
Re: [PHP] auto page generation
What you're looking for is basically what PHP is all about. Just read any PHP MySQL book and you'll find whatever you need.
