Re: Re: [PHP] Full-Duplex communication
Vinod, Interesting... Okay unless I'm mistaken, what you want to do can't be accomplished through PHP. However, you may want to take a look at libnet. http://www.packetfactory.net/Projects/Libnet/ I've always wanted someone to create a PHP interface for this- unfortunatly my C isn't quite there yet, but I'm working on it...

Now for your question - When the client wants to send data to the server, it just has to open a socket connection with the web server, and issue a GET or a POST request! if the connection is a keep-alive connection, and it has already been created, the client just has to do a GET or a POST without the need to connect().

Re: Re: [PHP] Full-Duplex communication
I don't think you're going to get Apache to hand you the socket. However, you can write a program using the standalone (CGI) PHP interpreter that will act like a server - check out http://php.net/socket_create_listen for more info. You could redirect from your standard web server to your listening PHP app running on another port. You'll then have to implement at least a subset of the HTTP protocol in order to get browsers to talk to you. Unfortunately, since you can't - to the best of my knowledge - fork a PHP program, you're going to have to do your own homebrew threading which will make life slightly complicated. miguel On 22 May 2002, Vinod Panicker wrote: It still seems like I havent made the problem clear enough.

Re: Re: Re: [PHP] Full-Duplex communication
Thanks for the reply Miguel, but here i'm not trying to implement my own multi-threaded server - exactly the reason why i'm using Apache / PHP. I could have made a listening server which is based on a multi-threaded or multi-forked model, but the time and complexities involved would be huge. Thats why I chose Apache / PHP. Now if what i'm asking for can be done, developers can easily leverage existing efficient server technologies (Apache) to build their own App servers. I know that there is no existing function in PHP that would allow it to retrieve the socket from Apache ;), all i'm asking for is a hack that would allow me to do it. I thought that i'd just as well post it on the mailing list before diving into the source code and trying to figure out for myself. No point trying to re-invent the wheel, right? Evan, that lib will allow me to create my own packets, but which socket do i send it to? Thats been the question all along. I think this is getting really interesting :) Tx, Vinod.

Re: [PHP] Mcrypt: Blowfish or Twofish or no fish? Part 2
Yes Jimmy, you are correct. MD5 is a one-way hash. Its used for getting a unique fingerprint of some data (like files / passwords etc) so that it can be compared with another MD5 hash. Thats the point of a hashing algorithm like MD5 and SHA1 - you should never need to decrypt the data. Refer to how Digital signatures and PKI works - they use MD5 hashes. The next question - A bigger keylength means stronger encryption - but it also means more CPU cycles. A bigger blocksize means that bigger chunks of data are encrypted at a time. Its always a balance that needs to be found over here - you cant use a keylength that is 2048 bits - it will give u the strongest encryption, but it will also take a lot of time. Tx, Vinod.

RE: [PHP] Mcrypt: Blowfish or Twofish or no fish? Part 2
Jimmy, You could md5 something and send it encrypted and then verify the md5, something similar to sharing keys...md5 is similar to a key...i use it as something similar to kerberos... And yes, MD5 is a one-way hash...which comes in handy... Just remember that bigger is almost always better. I would suggest trying all three (blocksize, keylength, and both) and see which one works best for you. You should see how your system deals with it and then decide...I like to have bigger keylenghts personally...

RE: [PHP] Servers, servers and more servers
When referring to an application server many times people are refereeing to a server that is running something like J2EE or EJBs or .NET with XML. They are actual applications running behind a web server. Some examples are BEA, WebSphere, or Jonas for Java apps. I have no idea about .net, not into that... If you are looking for a good Java one I suggest Jonas which is open source (free) and is fairly decent. I have used it for running applications with apache and tomcat running together... The Java apps with Jonas need to have something handle the web front-end which is Tomcat for apache Thanks, Ray Hunter -Original Message- From: Stephen Tredrea [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 22, 2002 1:06 AM To: [EMAIL PROTECTED] Subject: [PHP] Servers, servers and more servers I'm trying to put together an architecture for a web environment and have a newbie question regarding PHP and application servers...

Re: [PHP] Full-Duplex communication
Hi Richard, Thanks for your suggestion. Yes, Apache is the wrong platform for the server. What would be ideal is a custom designed TCP based multi-threaded server. Since we had lots of constraints, we went in for Apache / PHP. What i'm trying to do is to reduce the number of compromises being made in this architecture. If i have a long running script, the script is still polling the database, wasting precious server CPU cycles. Having an open socket on which the server calls select() is much less CPU intensive. Instant is how the response should be. Thats why i'm clamouring for the socket so that i can send data directly to the client, from a C++ binary or maybe another script. And to have the script running for hours, i would have to change the script timeout to a ludicrous setting, which would leave open many more possiblities for other problems. Tx, Vinod.

Hi, I believe that twofish has been successfully broken, so use blowfish instead.

We are talking abt a production system here which needs to be optimised. I cant honestly go ahead for a solution that would involve such a huge re-write :( though i'd love to do that using PHP. Just wanted to take the chance to give a huge CONGRATS to the PHP dev team for making such an AMAZING server-side scripting language.

Re: RE: [PHP] Mcrypt: Blowfish or Twofish or no fish? part 3
There is no use of hashing in file-encryption except to use it as a check - to see if the decrypted file matches the original file. To do this check, you can use either MD5 or SHA1. The choice is urs. If ur looking for a good encryption algorithm, you might want to consider AES (Rijndael). It supports encryption using different key sizes as well as all modes. You can take your pick from ECB / CBC also. For binary file encryption, i would recommend ECB mode. For text files, it would be better that you use CBC mode. Tx, Vinod.

RE: [PHP] Mcrypt: Blowfish or Twofish or no fish? part 3
File hashing is used to take a hash of the clear text. In this way, you can append the hash to the encrypted text. When decrypting, you remove this hash, decrypt the rest of the file, hash this decrypted file and see if the two hashes match up. If they don't then an incorrect key was used with the algorithm (or the data was corrupted somehow). Hashes are typically used as sanity checks in this way.

Re: RE: RE: RE: [PHP] Mcrypt: Blowfish or Twofish or no fish? part 3
Thats why lots of people like Blowfish, including myself. I am using it in a production environment with PHP and mcrypt. In ECB mode, the blocks are encrypted independently, whereas in CBC mode, the blocks are encrypted with information based on the previous block. What this means is that if a particular block which was encrypted using ECB mode is decrypted, it would show the plain text, whereas it wont happen if the data was encrypted using CBC mode. Plain text files can be seen and understood, whereas its much more difficult to understand if the crack attempt on a block of binary data was successful, since the data wont necessarily make any sense.

eval ('?'.$var.'?php');
if you want to eval usual php scripts.
(We close the ? then comes the content of the php script which also can
contain
html and then we reopen ?php again)
So if you have a file:
?php
include('test.php');
?
and you say
$var = ?php include('test.php'); ?;
you'll result in
...
eval(??php include('test.php'); ??php);
which will evaluate normally.

Hi.
I'm changing my website to one based on My-SQL which will help with
organization and searching etc. Hopefully, the code for all the pages will
be stored in the database too.
However, I cannot get PHP to parse / execute the code stored in the
database. The script
$query = mysql_query(SELECT * FROM pages, $link);
$result = mysql_fetch_array($query);
print $result['4'];
gets the content of the page (column 4 of the database) but displays
include(common/counter.php); include(common/navbar.php);
to the screen instead of opening and including these two files in the
output.
Is there something I need to do to the result to make it executable? Might
I
need a \n between the two lines of code?
I'm using Win 98, Apache 1.3.19, PHP 4.2.0 and MySQL but I'm not sure
which
version! (fairly recent though)

[PHP] Re: JavaScript vs. Header redirect
note:
you should use $array[test] if test is a string
and $array[test] if test is a constant.
do not use $array[test] if you mean the string test.
$array[test] will also work, if test is a string.
Php then tries to look for a constant with name test,
won't find one and evaluate test as string.
But as soon as you define a constant with the name test,
it won't work as expected:
$array = array();
$array[test] = hello;
define(test, thetest);
$array[test] = bye;
print_r($array);
will output:
Array
(
[test] = hello
[thetest] = bye
)
This could also happen if the php dev team decides to set a constant
with the name test. Therefore always use for string-keys in arrays.

Re: [PHP] Smart Navigation
Interesting topic, although highly off-topic. I just had a quick kick around, and found this page: http://msdn.microsoft.com/downloads/samples/internet/default.asp?url=/Downlo ads/samples/Internet/ASP_DOT_NET_ServerControls/SmartNav/default.asp Doesn't really say HOW it does it, but here's the interesting part: I'm already experiencing simular benefits as described here, on PHP sites I've developed (and all over the web), using IE 5.1.3 Mac. On pages that share identical content, it doesn't flicker, and yes I'm seeing the other benefits (state, scroll position, etc) as well. Here's what they say it can do: 1Eliminates the flash, or flickering, caused by navigation. 2Persists the scroll position between page navigations. 3Persists element focus between navigations. 4Retains only the last page state in the browser history. I don't know how much can be done on the server to help this. Points #2-4 are client-side issues IMHO, and the only interesting one is really #1. You can emulate this sort of application feel in many ways. For starters: 1 FRAME will only refresh content in the frame specified 2 IFRAME allows you to embed content (HTML files) inside each other... same as a FRAME, but I like to think of it as a floating frame that can be positioned in-line with other HTML elements (like inside a table, block of text, etc). 3 CSS and layers. Load a whole site in (hidden) and use javascript to switch between content layers that have already been loaded. Either way, I can't imagine what can be done on the server side to help this, and it isn't exactly PHP related so far :) Justin on 22/05/02 8:09 PM, Fred Forsyth ([EMAIL PROTECTED]) wrote: Is there any way to emulate ASP.NET's smartNavigation trick?

[PHP] Re: substr....what does this mean? (newbie)
Hi,
first take a look at this page:
http://www.php.net/manual/en/function.substr.php
if (substr($text, -1) == .)
substr($text, -1) will return the last character in string $text.
if it is a . the if statement will evaluate to true
and it'll do the following
{$test = substr($text, 0, -1);}
$test = substr($text, 0, -1) will return all characters of $text but the
last one and write them
to $test.
a negative third parameter means ommitting characters from the end of the
string.
The end of the string depends on the second parameter, which tells us where
to start.
if it is positive, start is the start and end is the end of the string,
if it is negative start is the end and end is the start of the string

Following on from my mail yesterday, here are the results of testing Billy's multipart content method on Windows browsers (Windows 98 to be precise): * IE 6.0 displays the boundary markers and content-type headers inline and also the contents of myfile.foo instead of saving it to disk. * Netscape 6.2.2 displays the HTML correctly and prompts regarding whether myfile.foo should be saved to disk but then appears to do nothing. * Netscape 4.7 displays the HTML correctly and begins downloading the file, only prompting for where it should be saved when the download is complete. * Opera 6.0 displays the HTMl correctly and prompts for where you wish to save the file, but incorrectly uses the script name and not the file name as specified in the content-disposition header. (It is possible that the behaviour of both Netscape 4.7 and Netscape 6.2.2 was in part due to interaction with Norton Anti-Virus.) Hope this is informative and not spam.

[PHP] ini_set('display_errors',1) not working.
I have the following in my php.ini file:
display_errors=Off
log_errors=On
error_log=filename
I want to turn on display_errors for developers, I'm attempting to use
ini_set to do this. I made a script like:
?php
ini_set('display_errors',1);
ini_set('log_errors',0);
ini_set('error_log',null);
ini
phpinfo();
?
(I added log_errors and error_log lines in an attempt to get this
working)
The phpinfo() shows that the local values for the variables I set as I
just set them, and the master values are those of the php.ini file.
Everything looks how I what it. If I add an error:
echo asdfadfasdfa;
The script behaves as it would in the php.ini, it displays no error and
writes it to the log. Does anybody have any ideas on why this isn't
working?

Hi I need to encrypt some fields in my mysql database. I need to ask a user for a pass when he enters the data, encrypt it and show him the data only if he enters the pass again. I know that pgp has a module that works with passwords instead of keys. I never tried this on Linux though. Any help will be appreciated. thanks berber
RE: [PHP] PHP PGP
calculate a hash of the pass the user enters and store that. When the user enters a pass again to get the data, then hash this pass and see if it matches the stored hash. If it does , then send the user the data. create a table that stores username, and hashed passwords for authentication.

Re: [PHP] voting using text files
Using file locking, if two people tried to use the script at the same time, wouldn't there be an error for one of them? My first guess at defeating this is having the script write a file named after the voter's IP. Have the file written to a different directory for whatever choices they have, then use readdir() to count the files in each directory, i.e. the number of votes for each choice. Then if that same IP tries to vote again, check it against votes already received and approve/deny it. I guess another way, have files written with consecutive titles, vote1, vote2, vote3, inside each one, store their vote choice, their IP, and a timestamp. I don't know, I'm not an expert!

Re: [PHP] voting using text files
Nick: I have to build a php 'survey' app. but cannot use a db, clearly text files are the way but I wondered, before I start if any of you have done similar and might offer any words of wisdom? Everyone thus far has recommended file locking. Another way is to create a new file for each vote, naming the new file with a date/time/microtime with each vote. You start or end the file name with something unique (a number or letter, etc) to each answer, OR, put the file in a particular directory depending on the answers. Then, it's easy to count how many people voted a particular way just by counting the number of files.

[PHP] Re: voting using text files
Text files are good providing the vote is simple. I would recommend using file locking, but to stop a user recieving an error if the file is in use you could get the script to retry after half a second or so. A good structure would be to have one file for each possible answer and each file contains the number of votes it has recieved. Then: -- Open file for the chosen option as read only -- Read the value in the file -- Close the file -- Increase the value by one using ++ -- Open the file again in write mode -- Lock the file -- Write the new value to the file - old one overwritten -- Unlock the file -- Close the file I don't do the file locking bit and I've never had problems but my script doesn't get heavy useage! You'll have to make sure all your files are CHMODed properly to allow them to be open and written to etc. I had a problem where my host did something to the system, changed the privelages and as a result my guestbook got wiped because it couldn't replace a file! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] voting using text files
On Wed, 22 May 2002, Jason Soza wrote: Using file locking, if two people tried to use the script at the same time, wouldn't there be an error for one of them? The second session would just have to wait for the first to finish (which should be an infinitessimal amount of time). My first guess at defeating this is having the script write a file named after the voter's IP. Have the file written to a different directory for whatever choices they have, then use readdir() to count the files in each directory, i.e. the number of votes for each choice. Then if that same IP tries to vote again, check it against votes already received and approve/deny it. Using IPs is a pretty lousy way of uniquely identifying users, especially for a purpose like this: 1. If I dial in with a modem, I probably get a new IP each time I connect, so I can vote as often as I like. 2. Many companies, ISPs, and even countries use proxy servers that aggregate thousands or millions of users behind a handful of IP addresses. One vote from China, Saudi Arabia or New Zealand and that could be it for the country. Likewise AOL. Try cookies or something. Still can be defeated by the determined ballot-box stuffer, but so can everything else that doesn't require human verification of identity. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] UTF-8/FormMail headaches
Hi all, I've got a problem with character encoding in combination with a FormMail-script (coded in PHP). Everything works fine as long as I stick to ISO-8859-1 as charset, but when I call the script from pages that use UTF-8 as encoding, special characters (e.g. those special chars with dots and circles above that we tend to use here in Sweden) end up garbled. The encoding is set with a meta-tag in case the document is in UTF-8, like so: meta http-equiv=content-type content=text/html; charset=UTF-8/ The server hasn't got any special charset configured, so it should deliver ISO-8859-1 (which is the default if I'm not mistaken) on those pages which haven't got that meta-tag. I can understand that the characters are garbled, using different charsets and all, but how can I make my FormMail-script to cope with both variants of encoding? I've played around with phpinfo() to see if the encoding is available in some environment variable, but I haven't find anything of interest. There's a function utf8_decode() in php that seems to work for converting the UTF-8 form data to ISO-8859-1 prior to sending the mail, problem is that it doesn't work all that well on data already in ISO-8859-1. I guess I need some way to determine what encoding the posted data is in? The content-type after the form has been posted to my FormMail-script always seems to be application/x-www-form-urlencoded no matter what I try. I've looked at the HTML-specs at www.w3.org and even tried to set the enctype to application/x-www-form-urlencoded; charset=ISO-8859-1 in an attempt to make the form-data use a different encoding than the rest of the page, but no success. I've also tried the accept-charset but I couldn't get that to work either. Anyone who has a clue on this? I guess I could alter the script somehow and add a new hidden field that indicate which encoding is used, and then decide whether to call utf8_decode() on the data, but I don't think that's a very nice solution.

Re: [PHP] UTF-8/FormMail headaches
For detection of encoding, perhaps you could include a hidden field with some shibboleth characters.

Re: [PHP] voting using text files
A good structure would be to have one file for each possible answer and each file contains the number of votes it has recieved. Then: -- Open file for the chosen option as read only -- Read the value in the file -- Close the file -- Increase the value by one using ++ -- Open the file again in write mode -- Lock the file -- Write the new value to the file - old one overwritten -- Unlock the file -- Close the file That's a bad method. You have to have the lock around the read and the write. With your method, 5 users might read the file, all getting 99 for the count, and then each one will try to seperatly write 100 to the file. So you lose 4 actual counts. You want to open the file, read it, update value, write it, unlock, and close the file. Using multiple files would just be a waste of space in my opinion. A locked file doesn't stop the script, it simply waits for the file to be unlocked and then continues on. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

can perform administrative functions. In the course of debugging it, I found
that the header(Location: ...) command worked perfectly until I called on
the $_POST or $HTTP_POST_VARS arrays (which seem to be synonymous). If I
removed the calls to the arrays, it worked fine. I looked through the
comments on the header function on www.php.net and through some of the
previous questions posted in the news group, and it seems like others have
experienced this problem as well. However, the most common situation noted

Re: [PHP] voting using text files
I think you guys are making this way more complicated than it needs to be. Anytime you start talking about locking files, you need to apply a huge reality check to yourself and sit down and approach the problem from a different direction. In this case could I suggest that you make use of the fact that appends of less than a blocksize are atomic. Therefore, why not simply append a single character to a text file for each vote? If you are voting for a list of things, assigning a character to each item and simply append 'a', 'b', 'c' or 'd' to your file. The size of the file instantly gives you the number of votes cast. Reading the file and counting the number of times each letter occurs using something like substr_count() will give you the number of votes for each option. That gives you a lockless and flexible system without the risk of deadlock or missing votes due to race conditions. -Rasmus On Wed, 22 May 2002, 1LT John W.

Re: [PHP] Re: JavaScript vs. Header redirect
Hi there!,
I've looked over this thread and from what I gather you want to know if you
can/should use JavaScript for redirecting, my usual way of going about
things is to put a JavaScript scriptlocation.href='page.aspx'/script
call in the head of the document (putting JS in the head causes it to
execute before the page is rendered, or should at any rate), and then I use
a meta refresh tag as my backup, set for 3 seconds.
That usually covers everything,
it stops spiders (google has a strong dislike of meta refresh), it redirects
JS users transparently, it's almost instantaneous for the
paranoid-shouldn't-be-let-out-of-the-ward non JS people, and it's easy to
code.
Plus it works in any server side scripting language, as it's all client-side
code.
Just my $0.02,
Dw.

Is there any reason I can't just use a JavaScript redirect from a PHP
login
handling script since I can't seem to get the header(Location: URL);
function to work? Any security concerns or anything else? As far as I
can
tell, all calls to header fail as soon as I attain variables based on a
POST
submission. See example below.
?
$username = $_POST[username];
$password = $_POST[password];
if(some username/password format verification) {
query the database
if($password matches pass in database) {
session_start();
$email = $Row[0];
$memberID = $Row[1];
session_register('email');
session_register('memberID');
