[PHP] Storing values in arrays
Hi, I think its easier to explain what I want to do.. so here goes: I want to store values in arrays for one minute and then write them to file. For example, everytime someone logs in I want their username to be in an array 1 or 100 or X people may login in 60 seconds...but it should only write all the usernames that logged in to disk every 1 minute. Ideas? suggestions? starting points or a link to a specific spot in the manual with a RTFM would be appreciated :) Thanks in advance, Ryan -- - The faulty interface lies between the chair and the keyboard. - Creativity is great, but plagiarism is faster! - Smile, everyone loves a moron. :-) - It's here!

why dangerous?
given that this page: http://php.net/manual/en/function.ctype-alnum.php
says, and I quote:

alphanumeric. In the standard C locale letters are
just [A-Za-z] and the function is equivalent to preg_match('/^[a-z0-9]+$/iD',

the 'D' modifier being the only difference in my example regexp and the
equilavent given on the

between dangerous and
not dangerous, if that's the case please explain (because I'm not seeing it :-)

re_format(7) on FreeBSD:
A bracket expression is a list of characters enclosed in `[]'.
(...)
If two characters in the list are separated by `-', this is
shorthand for the full range of characters between those two
(inclusive) in the collating sequence, e.g. `[0-9]' in ASCII
matches any decimal digit.
(...)
Ranges are very collating-sequence-dependent, and portable programs
should avoid relying on them.

Logically, it /could/ be more secure as it prevents access to any PHP code and thus any vulns in PHP itself. In practice tho', the login code and the small part of cpanel that the un-authed user has access to is unlikely to have any vulns. Even new injection attacks are unlikely to cause any problems, but you certainly can't rule it out. So, in principle, yes it is more secure; in practice, it probably doesn't matter.

Think I will do both. I can timeout the session with PHP.
Does adding mysql_real_escape_string make this secure to injection or should
I be doing something else?

$username = mysql_real_escape_string( $_POST['username'] );
$pass = mysql_real_escape_string( $_POST['pass');

[PHP] Php coding help - Newbie question
Hi Group,
A very newbie question. Might be discussed earlier, please forgive.
I am having a site in PHP ( not very great design ) which I need to
convert/modify to use functions. Such the code for connecting /
binding to Ldap is not repeated scripts are more readable.
The site deals with modifying / adding / deleting entries in a LDAP dir.
In each of the pages following is done:
?php
require 'validate.php' ;// validate.php checks if the user is loged in
$connect = ldap_connect(ldapserver);
if ($connect) {
bind ...
do the things
}else { echo erro..}
?
Also please advice what is a correct method of checking the user's
session. Currenlty I use a HTTP_SESSION_VARS variable to store the
user's login passwd . Each time the user hits the page these vars
are checked with the existing values in the LDAP (this is done by
validate.php).
Please suggest me some good starting point where I can start a fresh
with more compact/cleaner Code.
Many thanx in advance.
Regards
Ram

If this were XHTML or you were working with complete HTML documents,
then you would have a shot. Being HTML snippets, you are going to run
into problems (different encodings, possibility of entities, etc..) -
all of which need to be handled. You could probably hack the snippet a
bit to create a full HTML document, but there's still no guarantee it
will work correctly between different snippets.
On top of that, unlike working with XML, there is no way to output a
subtree of HTML. You would need to use the XML serialization routines,
which would most likely change the structure of your document (it would
be XHTML compliant now).

all input fields go to $_POST/$_GET depending on the form method you
use. so you don't have to create an array in the form itself.
just do it like
select name=\tyyppi\
and then you will have that value in $_POST['tyyppi'] or $_GET['tyyppi']

First off, thanks to everyone who helped me get started with a

I am moving along with a few additions and seem to be running into a
problem. The script I have works just fine, it's just slow when you
put some large files in it, the page takes awhile to load weither I'm
calling it through the php file it's self or through a include in an
html file.

The php script I'm using can be seen here: http://www.raoset.com/

Jason,
I'm not able to see your PHP script because when I navigate to the
script it is interpreted, not downloaded as text. Please copy the
script into a file ending in .txt if you'd like people to be able
to read it.
Is your thumbnail script slow because you're creating images on the
fly every time? If so, an obvious fix would be to cache thumbnails
on the server so you only have to create them once. The logic
could look something like:
if (thumnbail doesn't exist)
{
// create thumbnail save it to the server
}
// use existing file
Then you might consider putting the thumbnail-cacheing logic into
the script that lets people upload their images in the first place,
so there won't be so much processing the first time the thumbnail
gallery is loaded.
Sorry... Not used to working with PHP scripts... I forget you can't
just view source them :) here is the wheeler.php script:

so you want to print the same form fields for each iteration on the same
page?
then I would use a method like
echo select name=\record_$count_tyyppi\
which results in
select name=\record_1_tyyppi\ for record 1 and so on
and you can access the values in $_POST/$_GET like
$_POST[record_$count_tyyppi]

Re: [PHP] Storing values in arrays
Hey! Thanks for replying. Instead of CRON i was thinking of having a file created and check the creation time everytime someone logged in... if its less than 1 min then don't do anything, if 1 min or more old... write file... But then it wouldn't be written to disk every one minute if someone didn't log in for 3 minutes ;) True, but thats not the most important part... I guess I wrote it wrong, I meant that it should not write to disk before 1 minute... anyway... about the array saving any ideas? Thanks!

I would be using the Super Globals for this: $_SESSION, and don't store

Re: [PHP] md5
MD5 is a hasing algorithm.. one-way.. really only good for checking known values and keeping them 'private', like storing passwords in a database. That way, if someone breaks into your database, they don't get the passwords, only the non-reversible MD5 hashes of the passwords. To check a user's login credentials, you take the database value for password and you compare it to md5($password) that the user entered and see if they match. So the fact that MD5 is a well known algorithm doesn't really make a difference as far as security goes. Then again, RSA, Blowfish, etc are well known algorithms and are considered at least fairly secure too.. and are reversible. -TG = = = Original message = = = Hi, Does md5 really offer much in terms of protection?

Re: [PHP] md5
Be warned, crypto isn't a strength of mine, so any/all of this may be total BS. Ross wrote: Does md5 really offer much in terms of protection? Depends on what you're doing with it. AFAIK, md5's weakness comes in the form of collisions - it has been cryptanalysed to the point where it is no longer reasonable for high security purposes. It is possible to create two different strings (i.e. documents, passwords) that result in identical md5 hashes. It is likely possible to find alternate passwords if the md5 is known - if a user can get a hold of your md5'ed passwords, they may be able to come up with another password that will create the same MD5 hash, thus would be capable of logging in to the system. If what you're trying to protect is reasonably sensitive, don't use it to verify that a document hasn't been tampered with, and don't use it to hash passwords though salting may help. The algorithm is really well known. IMO, that's a good thing. I'd much rather have an algorithm that is well known, well analysed and *still* secure over an unknown and untested algorithm. I would like to hear your thoughts and poosible alternatives (mcrypt?) sha1 has also been cryptanalysed but should be more secure than md5. I think sha256 is believed to be secure. PHP 5.2 seems to have a 'hash' function that can generate many atypical hashes like sha256. jon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm not sure where your variables are being set. Are you relying on
register globals for $orgname? Is $formerror being set with default
values? What does ValidateString do? If you don't want to paste your
code to this mailing list you can use http://pastebin.com/. Perhaps
somebody smarter than me can figure it out, but I cannot until I see
more.

Look at your conditional. To my (new to PHP) eyes, you're setting
$result to whatever ValidateString($website, 2) returns. It should be:
$result == ValidateString($website, 2)
Some people countenance conditionals in the form:
ValidateString($event, 2) == $result
As this usually throws a fairly obvious error if you miss out the
extra equals sign. Personally, I don't like this but I can see it
helps one write more robust code the first time round.

Yep, never a good idea to just rote md5() the password. Best to add a
sprinkle of salt, that way you avoid precomputed lookups. For instance
if you're server ever got compromised and the attacker got your md5
passwords, if they already had a precomputed database then finding the
reverse of the hash would be trivial.

I got it working like this:
$counter = 0;
foreach ($arr as $value) { //make the form
...
print input type=\text\ name=\ArrUpdate[$counter][]\ value
=\$value[0]\\n;
$counter++;
}
Now I have array $ArrUpdate which contains sub-arrays with the update data.
This can now be processed with another foreach loop

And how does it work? does it create a sub-array of $_POST?
test it and find out:
echo 'pre'; var_dump($_POST); echo '/pre';
And is it documented somewhere in the manual?
more than likely.

$result = ValidateString($event, 2) is always TRUE, $result has had

[PHP] Getting domain out of a URL
Hi,
I receive posts from an open moderated forum that need to be filtered for
urls. I've successfully managed to trap any entires that use 'http://' 'www.'
with the standard '.com' '.org', '.net' endings.
What I need to do is to strip the prefix part ('http:// or http://www. or
'www') and suffix as well (the .com, etc.) I need only the domain name. I
can't seem to trim away the suffix part.
The code I've tried:
$_POST['request'] = . . The third has it all www.borko.worko.com and
meanders on. Then it stops.;
$check = $_POST['request'];
if (preg_match(@^(?:www.)?([^/]+)@i, $check, $match))
{
$host = $match[1];
(print brdiv class='center'
h4brbrbrURLs are not permitted
brbr
Click 'Back' on your browser and delete all URL references.
/h4brbrbr/div);
/* EXTRA 1: Added to see what's happening */
print h4 style='color:green;'$match[1]/h4brbr;
/* END EXTRA 1 */
$boom = explode(www., $host);
foreach($boom as $key = $host){
$boom[$key] = $host;
}
$booms = implode(www., $boom);
$out = (preg_match('[.com]', $boom[1], $match));
/* EXTRA 2: Added to see what's happening */
echo b style='color:blue;'The BOOM1 SPLIT Domain Name is:/b
{$boom[1]}brbrbr;
echo b style='color:green;'The OUT SPLIT Domain Name is:/b
{$out}brbrbr;
/* EXTRA 2 */
What ouputs:
Extra 1: . . The third has it all www.borko.worko.com and meanders
on. Then it stops.
Extra 2 BOOM1 SPLIT: borko.worko.com and meanders on. Then it stops.
Extra 2 OUT SPLIT: nothing
There's gotta be a better, simpler way of doing this. I want to check for the
string in the POST. If it's there, tag it, and be able to save it, and
re-enter just the domain back into future checks based on the IP address as
well.
Tia,
Andre

[PHP] dynamic lists
I'm a noob. My question is whether PHP can produce dynamic drop lists and if so what the tags are so that I can look them up. By dynamic drop list I mean the type where the options contained in the subsequent list depend on what was picked in the previous list without clicking submit. For instance: say the first list is of the states, then the second list updates to contain cities within that state as options. Thanks, Don

I would use a more detailed approach: http://pastebin.ca/319054
could you clarify alittle? (beyond not using the apache specific

function - I chose to go that route because I never run on anything
other than apache)
is the value of $headers['If-Modified-Since'] identical to
$_SERVER['HTTP_IF_MODIFIED_SINCE'] or *can* they differ (i.e. would
it be stupid to assume that apache 'normalized' the modidfied-since
string?)
they should be identical, the one thing, iirc, is that the
getallheaders() returns what exactly the client sent, so if the client
sent 'if-modified-since:' then the assoc array would be
$headers['if-modified-since'].
given that there may be difference in capitalization and the fact that
getallheaders() is apache specific it seems to me that using
$_SERVER['HTTP_IF_MODIFIED_SINCE'] would be better (not to mention saving
a function call).
is my code borked or merely not covering a number of edge cases related
to older or more exotic browsers - my code does output 304 headers
at the right time AFAIHT.
As far as i can see nothing is wrong.
After looking at rfc2616 i dont know why there is that $http_size
thing going on in the code i posted; must be from a very early draft
of HTTP/1.0 (as noted by the date in my comment)

'http://' 'www.' with the standard '.com' '.org', '.net' endings.
What I need to do is to strip the prefix part ('http:// or http://www.
or 'www') and suffix as well (the .com, etc.) I need only the domain
name. I can't seem to trim away the suffix part.
[/snip]
Have you looked at http://us3.php.net/manual/en/function.parse-url.php
Thanks Jay for the function reference, but it doesn't seem like it's what I'm
after since the url is packed into the text.
What i really need is something that will take the first part of an array
cutting the remainder after a delimiter word '.com'.
Something along the lines of:
?php
$boom[1] = ranchy.stuff.com and other junk;
$input = $boom[1];
$out = array_slice($input, 0, 1);
?
Part of my problem, I'm beginning to realize, is that the array '$boom[1]'
contains only one element. Is there a similar string function I could use
that would accomplish what I need?
If there isn't one you can always compose it from the ones already available.
That's programming.

RE: [PHP] One last try at this!
This is what I am trying to do, and for the most part it works, but it also
may be causing some of my other problems.
If $event contains invalid characters, I am returning a string that says
Invalid Characters So $result now contains the value 'Invalid Characters'.
Then $formerror['event'] = $result - is self explanatory.
If there are no errors nothing is returned and $result should contain
anything. But this doesn't always seem to be the case. This is one of the
problems I am having.
This is the code in a nutshell.
if($result = ValidateString($event)) { $formerror['event'] = $result;
function ValidateString($string) {
if(!preg_match(/^[-A-Za-z0-9_.' ]+$/, $string)) {
return Invalid Characters;
}
Thanks

I like #2. If you need a starting point, google for javascript dynamic select list FYI... Neither #1 or #2 are considered good practice for Accessibility/ADA compliance. If you are using a keyboard or screen reader to view your website, it will always pick the first one in the list and you won't have the option of even seeing the rest of the list. Basically, anything that uses onchange or onselect will cause accessibility issues. The only way to accomplish this is using onclick or submitting the form. that stance basically negates everything 'ajax', flash, video and everything considered to be remotely 'web2.0' - is the 'low-common-denominator' case always the correct choice? And what about the my-ajax-is-longer-than-your-ajax (or whatever's in right now (is in still a cool word?)) lemming-march mentality? I think 'correct' was the wrong word. still thinking what the right word should be. bare in mind I was playing devil's advocate rather than defending a particular stance. I understand the importance of accessibility but the practicality of most peoples' job in this sector means satisfying the requirements of a client that demands such dynamic functionality such as the auto-selection example given here. That's typically a result of poor user requirements capture. :) of course the level of requirement/functional specification one can do is dependant on (at least) 2 things: 1. budget - building a small (5000 euros) site leaves not much money for developing detailed specs, it easy enough to blow 5 grand on a preliminary investigation let alone something that resembles a fullblown spec. 2. client - can the client even comprehend the specs and the ramifications they entail, a small local business has no idea (or interest) in the problems, ramifications and technicalities of site building - he/she just want's a website. is there not an argument that screen-reader and [braille] keyboard software are somwhat responsible for being capable of 'keeping up' - given that an onclick can be handled why not an 'onchange' (in theory)? Yeah, wheelchairs can move along a sidewalk, so what's stopping them from walking up and down stairs? no doubt the economics of greed - technically it possible to, I mean Honda built a freakin' robot that runs up stair and I seen multiple axel wheelchairs on TV more than 15 years ago (anyone in England know the 'Tomorrows World' program from the time when it was still about real science? ;-) that were capable of traversing stairs. but applying the extreme accessiblity mantra to the stairs analogy would mean making stairs more or less illegal. should we sue companies out of existence because they have a set of stairs? should stairs be illegal? If you haven't written an open source browser on par with mozilla for blind people, has anyone actually achieved that? actually my comment was aimed purely at commercial software, which, for now, AFAICT is the only real option for disabled people - and it's not a cheap option either, so the bar is set very high in the economic sense, disabled people in a low/no income are often shut out purely on budgetary grounds. should commercial vendors that supply tools to enable disabled people be held to a [very] high standard? additionally it could be said that the only feasible proposition is to make the the enabling tools adapt to the environment they are intended to make accessible? to return to the wheel chair analogy: it's completely impractical to replace all stairs in the world with suitable ramps but it is technically achievable to build a wheelchair that is capable of navigating a world full of chairs. it's IMO polite to not raise the bar for them unless necessary. KISS and all that. there are plenty of multi-billion dollar corporations that pay nothing more than lip service to accessibility - those same companies are the examples alot of my clients point at when telling me what they want. (I'm painting with a broad brush here) if I completely refuse to 'raise the bar' then I'm going to be flipping burgers at sooner than I'd like - my clients will go else where. so I'm stuck between doing 'the right thing' and paying the bills - all this is rather a moot issue in a world where millions of disabled people don't even have access to running water, let alone wheelchairs - so extending KISS approach all the way down the line I would say fuck what's happening online completely and let's all try to make sure everyone on the

Does your included PHP script contain any functions? Or is it more like:
file1.php contents:
function my_function () {
if (i_feel_like_it) {
include(inc.php);
}
}
and inc.php contains variables at the global level such as:
inc.php:
$var1 = 2;
$var2 = 3;
Am I close?
