[PHP] fsockopen() to remote URL: what if remote URL times out?
I have a question about the usage of fsockopen() to open and scrape the contents of a remote URL: if the contents take a very long time to load on the remote URL either due to server or coding issues, is there a way for the socket on the PHP end to time out, that is, quit trying to scrape contents from the remote site and post a default message instead?

[PHP] checking status of a HTML checkbox
Hi,
If I pass a FORM (using POST) from one php script to another, which
contains the following HTML checkbox:
INPUT type=checkbox name=insurance value=yes
I know that the input will only be passed if the checkbox is ticked... but
how do I check if the checkbox was ticked and the value has actually been
passed ?
At the moment I am doing this:
if ( $_POST[insurance] == yes )
{
}
But is there a more accurate way of checking the exsistence of insurance
?
Many Thanks,
Shams

[PHP] Column size, user input and htmlspecialchars
Hi, No problems with my code but instead I'd like some views on the best way of doing the following: When I read in a text field from a users HTML form, I will allow them a maximum of say 50 characters. So, I define the corresponding field in MySQL to be VARCHAR(50). The problem is that after I run it through htmlspecialchars() the size could have increased considerably, if there were for example 5 characters that got escaped, this would mean possibly an extra 25 characters to the original meaning it would be truncated considerably. One option is to store the input without using htmlspecialchars, and then when I display the information wrap the output in htmlspecialchars. I don't like this though as I've got several text fields which will be hit very often, it seems too much of a performance penalty. The other option is to str_replace($text, '', '') so this gets round people embedding Javascript and other HTML but means non-malicious less-than characters would be lost, however I would only need to use htmlspecialchars when outputting to an input box, not just as plain text, so not so much a performance penalty as the first option. How do you guys go about resolving this situation? Thanks for any input, Jim. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

called, so I need some precious help here. Anyone please?
99% of the time scripts such as this operate in the following manner.
Lets say the script responds to emails sent to [EMAIL PROTECTED] The
server which handles mail for example.com has an alias for the address
foo which actually points to an external script. Most MTA's will
allow you to do this (yes, even some for Windows, believe it or not).
For example, in sendmail you could place a line in /etc/aliases or
/etc/mail/aliases (depending on your installation) like the following:
foo: |/usr/local/bin/myscript.php -s
This would cause sendmail to send the text of any email sent to foo
to myscript.php's stdin via a pipe. (Be aware that some sites with
sendmail use the sendmail restricted shell, so there are some extra
steps involved in getting an alias like the above to work, which I
won't go into here).
myscript.php would need to be a PHP CLI script, meaning that it's
chmod'ed executable and has:
#!/usr/local/bin/php
at the top or something similar. Then this script would have to read
from stdin and parse the text it receives via regexes or some other
method to determine how to handle it. The script would receive the
full message, including all headers.
In PHP you can read from stdin by opening a filehandle to it:
$stdin = fopen('php://stdin', 'r');
Although in PHP 4.3.0 there are CLI specific constants defined which
obseletes the above. For more info:
http://www.php.net/manual/en/features.commandline.php
I've implementing a script like this before, but unfortunately it's
written in Perl. Many of the concepts are similar, though, so if you
know any Perl at all and think it may help you I can send it to you
off-list.

I agree with Edwin on this one. What's the for?? Could it be you want to be doing this: $templatestring = include(/pathto/email_template.php); $message = HTMLMESSAGE.$templatestring.HTMLMESSAGE; ?? When you include() a file with PHP, it DOES parse the included file (although in the included file, anything not between ?php and ? tags will be considered plain text. Put another way: Even though the include statement in the main document is ALREADY between PHP tags, the parser looks for an opening PHP tag in the included file to find where to begin parsing - anything before that opening tag is echo'ed out as plain text).

RE: [PHP] Re: fletcher's checksum
-Original Message-
From: Dave Gervais [mailto:[EMAIL PROTECTED]]
Sent: 09 January 2003 21:36
Here is the C code. There is a decode function, but I don't
need it in
PHP because I have a C program listening to serial port on
the other end
that will validate the checksum.
/*
* operator fletcher_encode
*/
fletcher_encode( buffer, count )
unsigned char* buffer;
long count;
{
int i;
unsigned char c0 = 0;
unsigned char c1 = 0;
* ( buffer + count - 1 ) = 0;
* ( buffer + count - 2 ) = 0;
for( i = 0; i count; i++)
{
c0 = c0 + * ( buffer + i );
c1 =c1 +c0;
}
* ( buffer + count - 2 ) = c0 - c1;
* ( buffer + count - 1 ) = c1 - 2*c0;
}
My problem with PHP was with the unsigned char.
Well, as I guess that would effectively be an integer in the range 0-255, I'd just
treat it as an integer and reduce it modulo 256 in places where it might overflow that
value.
Exactly how this translates into your PHP code depends on how you're translating the
rest of the routine, and especially what you turn buffer into, but the loop might go
something like:
for ($i=0; $i$count; $i++):
$c0 = ($c0+$buffer[i])%256;
$c1 = ($c1+$c0)%256;
endfor;
You could also do the modulo 256 reduction by doing a bitwise and with 0xff (or 0377,
or 255), of course -- this is likely to be more efficient, and may, depending on your
point of view, be more obvious as to what's going on. Then your loop might look like
this:
for ($i=0; $i$count; $i++):
$c0 = ($c0+$buffer[i])0xff;
$c1 = ($c1+$c0)0xff;
endfor;
Hope this is helpful and sets you off on the right track.
Cheers!

You dragdrop files there and the same will occur remotely. Not a very secure way, though. 3. FTP integrated tool: Get a good editor that has some FTP integration. It will means that when you `save' a file in your editor, it will automatically FTP that file on the server. A very tool-dependent way but can work. Very cruel when something goes wrong, though.

Re: [PHP] Auto Include a Function
Hi,
I haven't seen anything like that implemented yet. I have my functions
logically grouped/organised into files... I only include the file when
needed. Some files (like my string functions and DB functions) are
auto-prepend (a php.ini directive) auto-included into every script, which
does save me some time.
However, it occurs to me that there COULD be a way to implement what you
want... whether it's worth the grief or not is a different discussion
altogether :)
For starters, you can check whether a function has been defined using
function_exists(). If it doesn't exist, you could then include() it,
assuming that you have one function per file, and each file named the same
as the function, or with decent naming conventions.
There are two functions which can call your user defined function
call_user_func_array() (use an array to pass multiple arguments) or
call_user_func() aparently for single arguments.
I haven't used either of these.
In psuedo code, here's what i'm thinking:
?
function theWrapper($targetFunction,$args)
{
if(!function_exists($targetFunction))
{
$file = functions_lib/{$targetFunction}.func;
if(file_exists($file))
{ include($file); }
}
$result = call_user_func_array($targetFunction,$args);
return $result;
}
?
so, let's say I have a function called foo, saved as a file foo.func in the
/functions_lib/ directory
?
function foo($animal,$name,$color)
{
return I have a {$animal} named {$name}, and it is {$color};
}
?
I could the call foo() thru theWrapper()
?
$args = array('cat','muffins','black');
echo theWrapper('foo',$args);
?
*Totally* untested code, but in theory this should echo
I have a cat named muffins, and it is black
Now, this still needs a LOT of work. theWrapper() needs lots of error
handling code... i haven't allowed for missing functions/files, missing
arguments, or anything else... I guess this was more of a proof of
concept... perhaps something to get you started? Or perhaps something to
make you say nah, too difficult :)

Hi,
This may exist, but I haven't been able to find it, and I think it would
be REALLY helpful and convenient.
The idea is this:
When you write a script and call a function:
?php
$whatever = previously_uncalled_function(one,two);
?
PHP would automatically look for a file named
previously_uncalled_function in your /include/functions/ directory.
This would eliminate a LOT of include() and require() calls (or at least
make them automatic) in a script. The function would only get read in
if it was used.
This would be very convenient. When you create a new function you drop
it in that directory (with a very specific, unique name, of course), and
it can immediately be called anywhere in the site. And, you only incur
the disk IO to read it when its used for the first time in a script.
The 3 things I want to avoid are:
1) Explicitly including every function, every time it's needed.
2) Disk IO of including a function when it's not needed.
3) Taking the easy route and including a file with a bunch of functions
when most won't get called.
Does this already exist, or is this a good idea (if not, any reasons
why)? I personally would love to see it implemented if it isn't
already.
Thanks,

Re: [PHP] something annoying about includes/relative paths.
Sean Malloy [EMAIL PROTECTED] wrote... :
Moving to PHP from an ASP backgroun, I always found one thing really
annoying about PHP.
With ASP, you could have a file structure such as:
SYSTEM
|--HTML
| |--header.asp

|--LOGIC
| |--engine.asp
|
|--core.asp
in default.asp, you would
!--#include file=system/core.asp--
in core.asp, engine.asp would be included as such
!--#include file=LOGIC/engine.asp--
in engine.asp, header.asp would be included as such
!--#include file=../HTML/header.asp--
Its a bad example. However, it demonstrates that the relative path for each
include changed depending on what file was being included.
PHP doesn't do that. Which is kind of annoying, but you get used to it.. But
I've come up with a work around.
Wrong. PHP doesn't care that much about these paths themselves, both ASP
and PHP need the path to give it to the filesystem and to retrieve the
file pointer. Which means, on the same system both PHP and ASP would
behave the same way to get the same files from the same locations.
Difference stays in the fact that you can also configure it in the
php.ini file. For instance, if you add '.' in php.ini then every file
request will be relative to your current location (check it, it might
not be set for you - include_path directive).
htdocs/index.php
include('./system/core.php');
dot `.' is the current directory *relative* to the current directory -
makes not much sense in many cases.
htdocs/system/core.php
define('CORE_PATH', str_replace('core.php', '', __FILE__));
a cute way to accomplish the above is:
define('CORE_PATH', dirname(__FILE__) . '/');
include(CORE_PATH.'logic/engine.php');
htdocs/system/logic/engine.php
include(CORE_PATH.'html/header.php');
and so on and so forth. searching for __FILE__, and removing the filename
from the output, gives you a sort of relative path hack.
Hope someone finds that useful

Re: [PHP] Databases vs. File Access
Totally depends on the data in question. I tend to organise my data in a mySQL database, for easy queries, sorting, categorisation, etc etc. However sometimes I associate a file to a record (eg a photo of a member or employee)... so the employee with the id 45 will have a photo stored in the filesystem called 45.jpg. I tend to keep raw-text-based data in a database, and binary or heavily formatted data (mp3s, giffs, JPEGs, PNGs, .doc's, .xls's) in the file system, attached to the database records. I've read that you get faster queries by separating bulky data from the simple stuff... this separation can be done with files, or with relational db tables... I guess it depends a lot on what sort of data, how you will use it, and which your prefer (file/db). One other bit of advice i've read: if you do have LOTS of files in a filesystem (1000's, not 100's), it's best to break them up somehow... by alphabet (a/, b/, c/, etc), year (2002/, 2003/, 2004/, etc), category (entrés/, mains/, soups/, deserts/, etc), etc. on 09/01/03 4:04 PM, Erich Kolb ([EMAIL PROTECTED]) wrote: I am going to be dealing with a ton of data shortly and my goal is to make it accessible via the web.

Re: [PHP] Informing a User of an Illegal Character in a post
Basically, you want to do a regular expression to see what characters are in
the username, and make none of them are illegal...
I currently have the rules of
5-30 characters
lowercase, numbers 0-9 and underscore (_) only
I achieve this with:
?
if((!preg_match(/^[a-z0-9_]*$/, $username)) OR (strlen($username) 5) OR
(strlen($username) 30) ) {
echo username invalid -- must contain only blah blah blah;
}
You could extend preg_match(/^[a-z0-9_]*$/, $username) to match more or
less characters to suit your needs, but I'm no expert.
[a-zA-Z0-9_-] would also include a dash (-) and uppercase chars
Best advice I can give you is rather than worrying about which chars might
do damage, think the other way, and only allow characters you trust.

Re: [PHP] Is this possible with php?
Hi, Where did he say he wanted to use Word to edit PHP files? AFAICT the idea was to automatically upload Word files, presumably to make them available on an Intranet for download etc. As for uploading a file automatically - PHP isn't going to do it. An app which can map a virtual drive in Windows would probably be the best bet - I think Windows has built in support for mapping WebDAV and FTP servers as shares so this may be a good starting point.

Currently I need to first save it on my desktop, then upload that copy to a php-supported server. Oh well, there are four ways to accomplish this. 1. Professional way: Using CVS. CVS (cvshome.org) is a system that allows you to version your files. This, in two words, works this way: in CVS, you `checkout' (update) a file, edit it, and save it (if somebody else edited that file while you edited yours both changes will merge). CVS is the most professional solution for this thing. 2. Simplest way: Use a mapped networking like Samba. This will mean that you will see your server just as it was a hard disk on your windows. You dragdrop files there and the same will occur remotely. Not a very secure way, though. 3. FTP integrated tool: Get a good editor that has some FTP integration. It will means that when you `save' a file in your editor, it will automatically FTP that file on the server. A very tool-dependent way but can work. Very cruel when something goes wrong, though. Again, Zend IDE and Edit Plus can do that. 4. The Geeky way: Edit all your files in a simple VIM or other fancy directly on the server by logging there with telnet or SSH.

That's good advice, but the explanation is not quite accurate. If you do not exit your script after a redirect, the remainder *will* be executed and any output it generates sent to the browser.

Re: [PHP] Medium to Large PHP Application Design
Nick, As PHP becomes more accepted in the corporate world, it is only logical that larger and more complex applications are going to be developed using it. To start I will state this: I am one of the consultants of a project run by 70 developers for the period of 2 years at the Ministry of the Economy and Finance of Italy. This is supposed to be the world's first or the second biggest project in the (depending on whatever size Yahoo is like, Rasmus is there :) The project is mostly in PHP/Apache/Linux and uses Oracle and PL/SQL plus a lot of other things like Java, Ruby, C/C++, C# and even old-friend COBOL and NatStar. Most of the whole thing is PHP/Oracle though. There are approximately 104 servers in all the regions of Italy and are some 5-8.000 authenticated users. Best part of PHP was not really the price (there were money) but the compatibility for all the technologies we needed to communicate within the framework. There are also parts written in other languages and PHP handles them just well. Normally, one chooses Java for such things as Java is supposed to be the most dymanic and flexible language. But, personally, I don't see it that way - I prefer PHP because of the faster development times what makes the application's quality much higher and things much quicker to implement. While there is an abundance of information out there about making specific things work, there seems to be a shortage regarding the big picture. Because of this, PHP is also cheaper - you need less time for debugging and researching online. Bigger you go - more you appreciate things like this mailing list and the tons and tons of online resources. Need a check for the email format? in PHP - a) Google / SourceForge / app you know has it. in 3-5 minutes you got it. in Java - a) What Sun's CD was that? b) What class was that? c) Is it copyrighted? d) Can it be used for free??? So, you end up making it on your own, even if Java makes all these `reusable components' you still need to tripple-check the things and so on As such, my question is this: What methods and techniques can be used to help design and build complex, medium to large PHP applications that are not only scalable, but maintainable and extensible? Obviously separating application and business logic from interface code is a given, but what about other things? Are the object orientated facilities of PHP currently worth really trying to take advantage of? If so, what are you doing to take advantage of them? Are design concepts such as design patterns relevant at this level? What frameworks, if any, currently exist to assist in rapid, structured development, and what specific benefits do they bring to the table? Everyone says OOP. But, in reality I'd say: OOP only for the things you reuse more that once. The rest of application should be written in plain concept of 1. Auto-prepend 2. Prepare XML output 3. Auto-append for the layout Which is something like, let's load a few classes every file needs. Then simply make the file's functionality based on params received and output some XML. The XML will then be used or laying out the page and the rest of the process. Everyone this way gets much a simpler framework to develop with. The important parts of a large PHP project, in my opinion, are: 1. High and solid standardization of the framework and coding. Meaning that everyone works in the same way and not `as he thinks is the best'. This will give the possibility for the team to work better together and move between the sub-projects easier. It's same in every language, so one should really care. 2. Have at least a one or two people who maintain the commonly shared libraries. This is, when someone says Hey, I want this code to my page too the team answers: which code? and then takes that code, creates a library component, document it and organizes it within the libraries. 3. All of the output for the application is better to be an intermediate mark-up like XML. This way you can have the designers who get XML and apply whatever templates to it. Programmers should never care how something looks - their output is plain XML and that is it. Other technics are good too - for instance Smarty if a good idea. But, I'd still prefer XML and then XSLT and then caching mechanism to avoid overload. 4. 30% (AT LEAST!!!) of thee development times should be spent for planning. That is - no coding just sitting with the pen and paper in the meeting room and designing the framework till everyone agrees. After that point everyone knows exactly what is where and things becomes very fast. 5. team should have tools already ready AND STANDARIZED for them to do the development. Thus, CVS is a must. No one should care what OS one uses for development workstation, but the way it is organized on the server should be once agreed and never changed. It is too expensive to change even a simple .htaccess file - take one hour from 70

where /devel might be missing (for production code) or /test (for a test

files included within index.inc, and we of course want to get the right

{ $DEVELDIR = preg_replace(|/.*/home/sites/\.php(.*)/[^/]*$|,\\1,__FILE__) ; }
# get the working dir
followed by
include(/home/sites/.php$DEVELDIR/includestuff.inc);# include our various

)
{

and, as you can see, gets the master config.php and functions.inc from

[PHP] NEW MSGproblem switching versions
redhat linux 7.3 apache 1.3.27 mysql 3.23.49 php 4.0.4pl1 (static install) mod_ssl-2.8.12 the box had php 4.2.3 installed on it originally. we had a mysql application that would only run with php version 4.0.4pl1 so we installed the old version of php and everything worked. then we ran autorpm with the 'interactive' setting (just downloading and not auto installing) and the application broke. when I run debug_phpinfo it says version 4.2.3. we have reinstalled php version 4.0.4pl1 and debug_phpinfo still says version 4.2.3 and the app. remains broken. yes we copied the php.ini file after the install. we checked the new php binary and its definitely version 4.0.4pl1. we're pulling our hair out. what are we doing wrong/do we have yet to do? thanks! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I see what you mean Khalid, but I only retrieve 1 entry at the time, so exploding wouldn't be the biggest problem I suppose.

I've posted this a few weeks ago with no response. I want to use an external email template as it were, so that the sales guys can edit it as they like and simply shuffle the variables around that they need $username and $password (either with or without the ?php ? tags). I don't want them mucking around in my code and potentially screwing it up. Not to mention having a huge 'email' text in between those HTMLMESSAGE markers is ugly as hell and ends up making the color-coding in HomeSite all kinds of whack at the end of it. I tried to use: $message = HTMLMESSAGE include(/pathto/customer_email.php); HTMLMESSAGE; But $message has the literal string ''include(/pathto/customer_email.php);'' instead of including the file. Grr.. (wouldn't it make sense that an include() should be parsed FIRST with the contents put in place basically? This seems like a 'bug' not a feature. I also tried: $filename = /pathto/customer_email.php; $fd = fopen ($filename, r); $message = fread ($fd, filesize ($filename)); fclose ($fd); But all the $username, etc. are treated as literals and if I use ?=$username? in the customer_email.php the field is blank (like it's being parsed but doesn't have a value for it or something), instead of being converted to their actual PHP values. I also tried to put the global keyword in the customer_email.php file at the top. Ideally I would like to set things up so we have varoius form letter emails and I can switch them around based upon say a special order code, where the $user/$pw is always the same (depending on the database user of course), but the email content is different formats. Is there no way to accomplish this? Am I not being clear on what it is I'm trying to accomplish? My final thought is to use some regex to search for ?=$username? in $message after it's all been read in, and replace it with the variable $username or make up my own tag codes like [!username!] or something like that. This seems like such a hack, when PHP should be able to do this natively somehow.

Re: [PHP] Sessions and Frames...
I highly doubt it. The server, and PHP, have absolutely no idea about frames and don't care about them, it's just handling page requests. Frames are a display feature in the browser and it's the browser that requests the various pages it needs for display. PHP is just getting a few page requests in quick succession and as far as I know, PHP is thread safe where it uses threads. Meaning it won't trip over itself. What may be slowing things down is the number of files the browser needs to download, which is a minimum of 9 with 8 frames. And that doesn't include any image files. Most browsers limit themselves to certain number of connections. IE for Mac defaults to 4 max connections and can be set as high as 8. So with 9 files to download the browser won't even request the 9th file until at least one of the first 8 is completely downloaded. And then you have the overhead in the browser parsing all those files for display. I don't know what your web page looks like, but perhaps Javascript, CSS and/or DHTML could reduce the number of frames being used. On Thursday, January 9, 2003, at 01:45 PM, Dale Schell wrote: All of the pages in these frames activate the session, and some of them modify session variables.

Here is the C code. There is a decode function, but I don't
need it in
PHP because I have a C program listening to serial port on
the other end
that will validate the checksum.
/*
* operator fletcher_encode
*/
fletcher_encode( buffer, count )
unsigned char* buffer;
long count;
{
int i;
unsigned char c0 = 0;
unsigned char c1 = 0;
* ( buffer + count - 1 ) = 0;
* ( buffer + count - 2 ) = 0;
for( i = 0; i count; i++)
{
c0 = c0 + * ( buffer + i );
c1 =c1 +c0;
}
* ( buffer + count - 2 ) = c0 - c1;
* ( buffer + count - 1 ) = c1 - 2*c0;
}
My problem with PHP was with the unsigned char.
Well, as I guess that would effectively be an integer in the range 0-255,
I'd just treat it as an integer and reduce it modulo 256 in places where it
might overflow that value.
Exactly how this translates into your PHP code depends on how you're
translating the rest of the routine, and especially what you turn buffer
into, but the loop might go something like:
for ($i=0; $i$count; $i++):
$c0 = ($c0+$buffer[i])%256;
$c1 = ($c1+$c0)%256;
endfor;
You could also do the modulo 256 reduction by doing a bitwise and with
0xff (or 0377, or 255), of course -- this is likely to be more efficient,
and may, depending on your point of view, be more obvious as to what's going
on. Then your loop might look like this:
for ($i=0; $i$count; $i++):
$c0 = ($c0+$buffer[i])0xff;
$c1 = ($c1+$c0)0xff;
endfor;
Hope this is helpful and sets you off on the right track.
Cheers!

Re: [PHP] PHP/Oracle Command line Segmentation Fault
Are you saying that OCILogoff gives you the segfault?
It's very strange because OCILogoff is actually an empty function -
all the contents of that function is commented and is there only for the
backwards compatibility reasons. Zend API ends OCI sessions
automatically as script's execution ends.
Do what, try removing the last function from your script and run again.
If the segfault happens again submit a bug report at http://bugs.php.net

Session Destroy will work if you provide the user a way to log out of the website. But if the user closed the browser then that's it. Session Destory can't be used because the browser is a client side and Session Destroy is a server side. So, once the browser close, it doesn't contact the server before closing. You're only option is to clean up the session data from the webserver as I usually have done. I also use the database to find out about the session id and the timestamp it was updated.

Well, I've developed a database application with PHP and MySql, I used sessions. While developing I used my own computer as a web server - Windows 2000 Pro, IIS 5, PHP 4.2.3 via ISAPI. And all my code was tested successfully while my computer is the server and the client. Now after moving the sources to the server (Windows 2000 Advanced Server) and exporting the MySql database to the server, the application fail. While debugging I got to a firm conclusion that the sessions doesn't work well. I copied the php.ini to the system root on the server and it still doesn't work.

[PHP] Parsing a directory for specific files
Hi, does anybody know how to solve the following task? I'd like to generate a dynamic page, which contents come from txt-files. The files will be in a directory called content (from the page: ../content) and they are labeled with date and (within one day) increasing numbers, e.g. 20030108-1.txt, 20030108-2.txt, 20030108-3.txt, 20030109-1.txt, 20030110-1.txt, 20030110-2.txt The script should parse the file names and get the most recent five ones! The text inside should be included in the page - but this is not the problem, the task mentioned above is the problem! Thx in advance for these who can deliever solutions or ideas!

Re: [PHP] Encrypt in Javascript and Decrypt in PHP????
The way you want it can be securely done only using asymetric
encryption, which is not available to JS.
Do you really need to encrypt user_id? You could use md5 to hash
password with some random string,
store the hash in a hidden field and erase password. On server side if
the hidden field is set compare it
whith a hash you create with password and the random string (keep the
string as a session variable, don't
pass it as a form hidden field). If the hidden hash field is not set,
use normal procedure.
code:
server:
$_SESSION[random]=create_random_string();
client:
function onsubmit(form) {
form.hiddenfield.value= md5( md5(form.password.value) +
form.randomstring.value);
form.password.value='';
return true;
}
server:
if($_POST[hiddenfield]) {
$res=mysql_query(SELECT * FROM users WHERE user='$_POST[user]'
AND
'$_POST[hiddenfield]'=MD5(CONCAT(password,$_SESSION[random])));
} else {
$res=mysql_query(SELECT * FROM users WHERE user='$_POST[user]'
AND password=MD5($_POST[password]);
}
this example assumes passwords are stored as md5 hashes in the database

I'll look into this and try it out. The only thing that is important to me
is that the password get encrypted before transmitting across the internet.
I'm not worry if the JS is disabled because if it is then the login will

RE: [PHP] Header information ...
Hi Anders,
You can't send a header to the browser once output has been sent. The
header() function should be before any other output on your script. Further
more, because the script isn't terminated after the header() function, and
you usually do not want to continue running it, an exit() should directly
follow.
e.g.:
Header(Location: main.php);
exit();

Daniel Kushner

RE: [PHP] checking status of a HTML checkbox
Also look at empty(). I don't know if the $_POST array will send the key if
it as no variable. I know on a regular post it does send the variable, but
it has no value. I have used isset with just receiving post data and got
strange results. On one I had an isset statement that ran a result that
bypassed some code. When is submitted the form I got results as if the
isset was being executed and the code was skipped. Just to make sure this
was the case, I added echo hello; on the first line of the isset bypass
coding and after running the script I got the results without the bypass. I
took the hello back out and it bypassed! So adding the hello statement
affected whether isset gave a positive or negative response. The variable
isset was checking in this case was not being sent with a value. I changed
to empty() and got the result I was looking for. If $_POST sends the key
but not a value when you submit the form without a value assigned to the
variable then isset may not always work.

[PHP] PhP 4.3.0 Relative includes and Apache Alias problems.
Greetings,
Why is that, that when we try to issue a include statement, which has any kind of
Relative path in it, it will fail if the php script is mapped into apache web tree
by Alias Statement ?
An example: We have:
/a/b/one.php
/a/c/two.php
/a/three.php
Apache Alias stament is:
Alias /test /a/
If we run: include('../c/two.php'); from one.php, it will result in error: failed to
create stream: No such file or directory.
If we run: include('c/two.php'); from three.php it will result in suiccess.
If we run: include('./c/two.php'); from three.php it will fail as in first example.
If we just copy the whole /a into the web server document root, all examples will work.
Is that some kind of security feature or a bug ?

RE: [PHP] session_destroy problem
Question...Do you know if Mozilla runs a browser instance that might handle the process after one of the browser windows is closed? Right now the situation is that IE closes the session when the window that opened it closes. I have a site that is authenticated and then runs sessions on the authenticated user. If you close the browser window and open another one, you are prompted for the login and password and have your new identity/session. On Mozilla if I close the window actively on the site and have other windows up on other sites I can open another Mozilla instance and return to the site and it still has my session open and identity. I have to close every Mozilla instance for the session to close. If Mozilla is run by one central process I would think maybe it could do this onwindowclose behaviour?

Re: [PHP] Mysql/php database performance question
Oh, sorry, i should have remarked that all of the columns should be fixed width (CHAR) for this optimization to take effect, since if even one of the columns is variable width (VARCHAR) the whole row will be variable width, and it will be no use to change to CHAR.

I don't know the php internals, but my guess is yes, each session_start() locks the session file and the lock is released when you session_write_close or your script ends, otherwise some session variables could be lost.

Re: [PHP] Session Expiration?
Ok I think I understand this better, my garbage collection is working but I just didn't see it before. Until I check to see if the data was actually being deleted from the /tmp directory (der!). I was using just one browser to test this. So when I navigated through some test pages passing the PHPSESSID in the url and let it expire, the session_start() wouldn't do a garbage clean up against itself (if that makes sense) being the parent browser. Now I didn't see the garbage clean up until I launched the second browser and when it ran the session_start() it cleaned up the expired session of the first browser, thus any other activity on the first browser would cause the browser to go back to the login page.

First are you sure the data was not deleted? If the cookie is still set in your browser a new session file will be created with the same session id. I believe you adjust the session gc and the session max lifetime, additionally if you are concerned about someone bookmarking a sessionid or storing it in history take a look at the session.referer_check configuration directive: ; Check HTTP Referer to invalidate externally stored URLs containing ids. ; HTTP_REFERER has to contain this substring for the session to be ; considered as valid. session.referer_check = Obviously it wont work with some browsers and referer is sent by the client but every little bit helps.
