[PHP] MySQL password()
Hi all,
I do this:
dbconnect();
$query=SELECT * FROM users where username='$PHP_AUTH_USER';
$result=mysql_query($query);
$list=mysql_fetch_array($result);
if ($PHP_AUTH_PW !== $list[passwd] || == $PHP_AUTH_PW || all !=
$list[domain]){
Header(WWW-authenticate: basic realm=\EMM\);
Header( HTTP/1.0 401 Unauthorized);
unauthorized();
exit;
}
}
Noe this bit:
if ($PHP_AUTH_PW !== $list[passwd]
My problem is that the password stored in MySQL was done with password(), so
it comes out similar to this as plain text:
072g307j9236a82h3u
How do I Un password() it?
I have RTFM but to no avail.
If you tell me to RTFM again, at least tell me what to search for ;-)

RE: [PHP] Resetting ID
What i want to do is delete the entire IDs and generate them again so that they are in one single order like 1,2,3,4,5... .like this. I suspect that if your table, as you use it, needs this ordering then you've got something wrong. It really shouldn't matter much what the internal IDs are. When you extract the data you'll be ordering it by some means that may or may not include the ID ie. You might sort by date or some other field in the table, in which case, the ID's are irrelevant - particularly if you're doing a select that excludes some of the data anyway. If you seriously need all your id's to be sequential and have no gaps then I suspect that about the only way you'll achieve it is probably to drop the contents and enter the information all over again. Of course, then you'll need to do the same again if you delete any information from the table and so on and so on... There may well be other ways, I've not really looked as I tend to think a reliance of this sort is counter-productive so I've never needed to look.

with

To my knowledge it isn't possible to decrypt the PASSWORD function in
MySQL (you need to use MySQL ENCRYPT/DECRYPT for that). However, it's
possible to use PASSWORD on the user-provided string too. You could try
the following code:
$query=SELECT * FROM users where username='$PHP_AUTH_USER' AND
passwd=PASSWORD('$PHP_AUTH_PW');
$result = mysql_query($query)
or die(Couldn't execute query!);

RE: [PHP] Re: Table formatting -- PARTIALY SOLVED
why would you expect a for loop to know whether there was an array returned
from the mysql_fetch_array($result). you haven't told it to check this. This
is why I suggested using the fetch_array() to control the loop and a counter
to determine when to start and end rows - did you not get that?

2 rows of 2 *NOT DIPLAYED* images which I don't have... like it was

Re: [PHP] Good books on sessions
Well, I have asked a couple of questions on this list, but they havn't really helped alot. Maybe you can help? My situation background is as follow: I have always written my apps in the following way: register_globals=on, so I allowed PHP to generate my variables for me on the action page, and if I cannot use a form to send variables to the next pages, I added them manually to the url. So, then I discovered sessions and thought my probelms were solved, only to discover that it uses cookies by default, and has to have the --trans-sid option compiled to have PHP handle the app if you don't want cookies ( like me, don't want cookies at all, or for that matter, anything that relies on the client's side). So, I couldn't just jump in and use sessions as I would not be sure that my app would work on any PHP4 system regardless of the options it was compiled with. ( Oh, I am writing my apps to work with register_globals=off now, so that shouldn't be a problem). So I started to look for a way to code with sessions that will not require cookies nor require any special compile features; the answer came in adding ?=SID? to all relative URL's in my app. Alas, that is where I'm at, and it's still not working as I would have expected. My problem is with the way my proposed app works/should work. I am trying to write an app that allows the user to log in, then add/remove projects to his list, then, when a project is selected, he should have access to all the relevan documents in that project, again allowing him to add/remove documents from the project here, and in the last step, when a document is selected, allows hime to add/remove/edit chapters to the document. My first attempt at using sessions with this failed miserably ( keeping in mind my approach of adding SID at end of urls). I have a back link on all the pages that takes the user to the previous step(s) and thus on the last page ( the chpaters edit/remove/add page), there is a link to go back one level, two and three levels. Yet, using these causes unexpected results. I think the problem comes in with overriding the value of the session variable. For instance, on the first page you have a login form, on the action page I session_register(username,password), and that works fine even when using the back buttons as the values are never changed. But, on the 2nd page I have the drop down select containing all the project names ( gets built with a while that reads all the project names from the project_table) and send over the project_id. On that actio page, I session_register(project_id); and it also works fine for all pages down stream, however, when I come back to that page to select a new project, it keeps the old variable... At first I did nothing special in the sence of assigning a value to the session variables, as I let the register_globals=on do it's trick, but later I explicitly said $project_id = $HTTP_POST_VARS[project_id]; But that also did not overwrite the value of the session var. In the end I was forced to again add all my variables to the end of the url, keeping the session solely for the username and password. I don't know if you would like me to post my code ( it is quite a bit already ) but I would really appreciate it if someone could look at it, and then point out where I'm missing the picture, as then I would have two pictures that I can compare and see where my reasoning failed.

Re: [PHP] Good books on sessions
Well, how exactly do you implement the back button? If it is a normal client-side back, then of course the previous value will be shown. If it is actually a forward-link to the previous page, then your logic on that target page is bogus. By the way, trans-sid is compiled in by default in PHP so should always be available. And it will fallback to sid mangling only if cookies are disabled. You would probably be better off just letting php manage this for you. -Rasmus On Tue, 30 Jul 2002, Petre wrote: Well, I have asked a couple of questions on this list, but they havn't really helped alot.

Re: [PHP] Good books on sessions
Yes, it is a forward link to the page, but as mentioned, that page contains a form with the selection options, and on that form's action page is where I don't see the values change, so the question should probably be something like how do I change the value in the session_var with the newly selected value? And oh, I almost forgot: Due to that fact that this type of app doesn't really have a logical end page, I cannot issue a session_destroy() anywhere logically ( except using a logout button), but that's not going to ensure that people use it... I would ideally like to have this app run on an intranet, where people will most probably have this app open indefinately, and thus I also battle with my logic of keeping a session alive. Thanks .

For instance, on the first page you have a login form, on the action page I session_register(username,password), and that works fine even when using the back buttons as the values are never changed. But, on the 2nd page I have the drop down select containing all the project names ( gets built with a while that reads all the project names from the project_table) and send over the project_id. On that actio page, I session_register(project_id); and it also works fine for all pages down stream, however, when I come back to that page to select a new project, it keeps the old variable... At first I did nothing special in the sence of assigning a value to the session variables, as I let the register_globals=on do it's trick, but later I explicitly said $project_id = $HTTP_POST_VARS[project_id]; But that also did not overwrite the value of the session var. In the end I was forced to again add all my variables to the end of the url, keeping the session solely for the username and password. I don't know if you would like me to post my code ( it is quite a bit already ) but I would really appreciate it if someone could look at it, and then point out where I'm missing the picture, as then I would have two pictures that I can compare and see where my reasoning failed.

[PHP] Credit Card Validation With Expiration Date
Hi the ML I'm looking for an algorithm or a free PHP Script which enable me to verify expiration date with a credit card number. Does anybody knows this ? Regards Laurent Drouet -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Credit Card Validation With Expiration Date
I'm looking for an algorithm or a free PHP Script which enable me to verify expiration date with a credit card number. Does anybody knows this ? It doesn't existcredit card number alogrithms do not use the expiry date in their formulas (at least I'm not aware of any that are). Also there is no way to actually check if a credit card is valid without using a company that keeps an online database of active credit cards. The most you can do is verify that the number provided could potentially be a credit card...and even then the expiry date has no algorithm attached to it...as long as it is past the present date there's no way to consider it invalid without cross-referencing against a database of active cards.

Re: [PHP] Good books on sessions
The trick is to not name your form vars the same as your session vars.
Keep them separate so you have full control of what ends up where. Also,
note that if you are not relying on trans_sid or cookies then don't use
SID. Call session_id() explicitly to get the session id. So, a quick
little mockup to illustrate this.
login.php:
?
ini_set('session.use_cookies',false);
ini_set('session.use_trans_sid',false);
session_start();
$sid = session_name().'='.session_id();
session_register('username');
$username = 'petre';
?
a href=page1.php??=$sid?Next Page/a
page1.php:
?
ini_set('session.use_cookies',false);
ini_set('session.use_trans_sid',false);
session_start();
$sid = session_name().'='.session_id();
?
form action=page2.php??=$sid? method=POST
input type=text name=form_foo value=?=$_SESSION['foo']?
/form
page2.php:
?
ini_set('session.use_cookies',false);
ini_set('session.use_trans_sid',false);
session_start();
$sid = session_name().'='.session_id();
session_register('foo');
$foo = $_POST['form_foo'];
echo You entered $foobr /\n;
?
a href=page1.php??=$sid?Back/a
I am ini_setting on each page to force PHP to not do trans-sid/cookies.
Would be easier to simply turn these off in the php.ini file.
When you hit the back link, $_SESSION['foo'] will exist on page1.php and
the form will get filled in with the previous value. You can then change
it, hit enter again and the session value will take on the new submitted
value because I have decoupled the form data from the session data and I
set the session var in page2.php.
There are other ways to do this, but this is probably the easiest method
to understand. Play with this simple example until you understand how it
works.
But again, I'd suggest letting PHP do session id handling for you by
letting it default to cookies and fall back to url mangling in the few
cases where cookies are turned off.

By the way, trans-sid is compiled in by default in PHP so should always be

Well, I have asked a couple of questions on this list, but they havn't

My situation background is as follow:
I have always written my apps in the following way: register_globals=on,
so I allowed PHP to generate my variables for me on the action page,
and if I cannot use a form to send variables to the next pages, I
added them manually to the url.
So, then I discovered sessions and thought my probelms were solved, only
to discover that it uses cookies by default, and has to have the
--trans-sid option compiled to have PHP handle the app if you don't want
cookies ( like me, don't want cookies at all, or for that matter,
anything that relies on the client's side). So, I couldn't just jump in
and use sessions as I would not be sure that my app would work on any
PHP4 system regardless of the options it was compiled with. ( Oh, I am
writing my apps to work with register_globals=off now, so that shouldn't
be a problem).
So I started to look for a way to code with sessions that will not
require cookies nor require any special compile features; the answer
came in adding ?=SID? to all relative URL's in my app.
Alas, that is where I'm at, and it's still not working as I would have
expected.
My problem is with the way my proposed app works/should work.
I am trying to write an app that allows the user to log in, then
add/remove projects to his list, then, when a project is selected, he
should have access to all the relevan documents in that project, again
allowing him to add/remove documents from the project here, and in the
last step, when a document is selected, allows hime to add/remove/edit
chapters to the document.

Try it this way, it will check if it is a jpeg and it has a horizontal

(you do not need the gd package for getimagesize())
/** Check for the type of the image : only allow jpeg's */
$im = getimagesize($_FILES['uploadFile');
if(!($im[2] == 2 $im[0] 0 $im[1] 0)){

The $im[2] being set to 2 means it is a jpeg other image types have a
different number, have a look at the getimagesize()function for details

If I DO stick with your suggestion of letting PHP do the url mangling,

ini_set('session.use_trans_sid',false); and ?=$sid? from your code to make it work
exactly as is?

I solve that problem. Apache was not runed as vpopmail.vchkpw. Suexec is

separate apache server as vpopmail.vchkpw user on other port. Now
vpopmail functions are ok.

Hello All, So, I've been using my own implementation of session handling which is mainly storing the userinfo in a cookie (an array, serialised and signed) but I'm starting to come around to the idea of storing this info on the server and just passing a session key about - but I have a couple of reservations, which I'm hoping someone can confirm or resolve : Assuming that sessions are stored on the filesystem by default: 1 How secure is this? Could someone with system level access simple wander into the session store directory and start browsing though the session data? 2 Are expired sessions removed from the filesystem automatically? How often is this garbage collection performed? 3 How can I get a count of currently active (I.e non expired) sessions? 4 Are there any performance issues to worry about doing it this way? 5 Is it quicker to do it this way or store sessions in a db using session_set_save_handler? Like the subject says, I'm after informed opinions on this subject rather than rumours and hearsay. As for my setup - it's a BSD box - Apache2.0.39 + PHP4.2.2 (apache module) + PHP4.3.0dev-Zend2alpha2 (cgi) - both compiled with pretty much everything.

Do the make install again and pay attention to what scrolls by and see where it puts the libphp4.so file. Then, make sure that's where Apache expects it. the LoadModule directive acts in conjunction with the one above all the LoadModules that tells Apache where to start looking for Modules in the first place. Some folks set that in httpd.conf to include the libexec part, so then your libexec in the LoadModule line is ending up doubling the libexec in the path and that ain't gonna work. If there are any *working* LoadModule lines, you can try digging around to find them on your hard drive, and make sure libphp4.so is sitting next to them, and then do the LoadModule the same way as the working ones. http://apache.org will explain all the stuff I just said in formal language. :-) Ok i followed what you have suggested and Apache didn't spit out anything on libphp4.so so I am lead to beleave it wasn't created.. my apache config like was #./configure --enable-module=most --enable-shared=max #--activate-module=src/ modules/php4/libphp4.a cheers Peter Peter - if you are still battling with this, perhaps you might try an alternate approach, where you first compile apache with dso support, then compile php as a loadable module. For guidance, here are the configure files I use for each: Apache ./configure --prefix=/usr/local/apache --enable-module=most --enable-shared=max You'll possibly have apache in a different place so may need to change the value for prefix. PHP #! /bin/sh # # Created by configure ./configure \ --enable-debug=no \ --enable-gd-imgstrttf \ --enable-gd-nativett \ --enable-sysvsem=yes \ --enable-sysvshm=yes \ --enable-track-vars=yes \ --with-apxs=/usr/local/apache/bin/apxs \ --with-config-file-path \ --with-config-file-path=/usr/local/apache/conf \ --with-freetype-dir=/usr/X11R6 \ --with-gd=/usr/local/src/gd-2.0.1 \ --with-jpeg-dir=/usr \ --with-mysql=/usr/local/mysql \ --with-png-dir=/usr \ --with-xml \ --with-xpm-dir=/usr/X11R6 \ --with-zlib \ --with-zlib-dir=/usr \ $ #--with-mnogosearch \ The two things you need specifically here are --with-apxs which allows the loadable module to be built, and the two with-config-file entries. The latter of these points to the directory where you have installed apache configuration files, and allows the php install process to find the apache config file and add the necessary entries to get php up and running. So the order of play is Apache configure make make install optionally start to ensure its all working PHP configure make make install Apache restart to re-read the config file That should get you up and running. I just did the php part earlier today to upgrade my laptop to 4.2.2 and it only took a few minutes.

Re: [PHP] Sessions - Informed Opinions
3 How can I get a count of currently active (I.e non expired) sessions? Count the number of session files. Can I be sure that the count will only include active sessions though? By definition, if the session file is there, it is an active session. There is no such thing as counting active users on the Web. You define a time window and count how many users accessed your site within that window. Once a session has been idle for a time than the configured session gc time, it will get deleted. I tend to do this out of band though. PHP has a mechanism for calling the session gc code, but I prefer to turn this off and run my own cron job that does this regularly. And yes, this is easier to manage if you have a database where you can do a simple count() query to get the number of active sessions. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Resetting ID
I have a table, with 4 columns. One of the column is ID, a Primary Key, which has Auto_Increment set on it. Now i have a lot of rows deleted and a lot of duplicate rows that will be deleted, and all sorts of stuff happening in the table.. the result is, that the IDs have become inconsistent. What you get is something like 5,6,9,10,25,32,33 .. and so on. With many IDs missing etc. What i want to do is delete the entire IDs and generate them again so that they are in one single order like 1,2,3,4,5... .like this. And so that any new entry in the table gets the ID accordingly. How can i do this? Who cares if your IDs aren't sequential?? All these IDs are for is to provide a unique identifier for each row. That's it. If the holes are causing a problem in your scripts, then you are using this column incorrectly.

[PHP] A somewhat unusual session question...
Hi all! The manual claims here (http://se2.php.net/manual/en/ref.session.php) that: /snip ...If session.save_path's path depth is more than 2, garbage collection will not be performed. /snip Anyone know why this is the case? And can you get around it? My scripts currently lives on a shered server and I wanted to get away from using /tmp (which is the default). I changed the session_save path in my .htaccess file to: /home/httpd/vhosts/mydomainname/httpdocs/sessions/ and created some sessions. The creation and destruction of sessions works fine as long as the user logs out correctly, but PHP fails to garbage collect sessions when the user just quits the browser. I've tried changing the session.gc_probability to 100 (and waited until session.gc_maxlifetime had passed), but it still doesn't work. Now I'm stuck with a bunch of deserted session files that don't seem to go away. Any ideas on how to solve this? /Lasso ([EMAIL PROTECTED]) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] need help reg. User Accounts
I am using PHP-4.1.1 on Linux, I wanted to know the difference between nobody user and normal user of operating system. None. Nobody is an ordinary user. However, ordinary UNIX users can be set up in all sorts of ways. This question just came to mind when, neither nobody's directory nor any entry was not found in /home or elsewhere. That's deliberate. The nobody user is set up with very few resources or privileges and is then used to run things like the web server. If a hacker can exploit a weakness in the server to gain control and issue commands as the user running it, the potential damage is limited to what that user can do, which is not much.

[PHP] Re: ORDER BY from 2 tables
I am not sure what exactly you mean. If you are talking about a regular query then: SELECT tblTable1.hits, tblTable2.hits FROM tblTable1, tblTable2 ORDER BY tblTable1.hits; If you are talking about combining the two tables so that all your 'hits' are in one column then there are a few ways to skin that cute little kitten (in order of difficulty): 1) Check to see if your databae supports UNION clauses. 2) If not, make a table with the data from the first table then append the data from the second table. Then query for your combined results and delete the table from the database. You may run into problems if more than one person tries to do this at a time, so be careful. 3) Or. create an array using data from the first set then loop through the second set adding the data from the second set. Then sort. Good luck and keep us posted.

Re: [PHP] Good books on sessions
*shakes head a bit*
I'm not REALLY sure what the problem is here, but let's take a step back.
A session ID is a unique, random number assigned to a user as they kick
around your site.
To maintain state (a session) across multiple pages, you pass the session id
around. This can be done with the URL or cookies. Yes, trans_sid is in
there as well, but all it does is re-write URLs.
No surprises so far.
You then assign variables to the session. If you're using PHP = 4.1, I'd
use $_SESSION['varname'] = value; rather than session_register(), because
it's a lot more logical, and clearer to think through.
Furthermore, the manual tells us NOT to mix use of session_register('var')
and $_SESSION['var'] = 'value'... so, pick a method, and stick to it...
since the $_SESSION array is the new way, I'd be going with it.
So, the first two session vars YOU assign after the user logs in is the
username and password (I wouldn't register the password).
$_SESSION['username'] = justin;
$_SESSION['password'] = secret;
Then a few pages later, they pick an option from a pull-down list, and you
assign another variable to the session:
$_SESSION['project_id'] = 45;
The user clicks through a few more pages, and later wants to work on a
different project, so you link them through (forward) to the options page.
They select a new project from the pull down, so you need to overwrite the
old project_id session var with a new one:
$_SESSION['project_id'] = 74;
Now, when they kick around through pages, they will be doing it under
project_id 74.
If you wanted to delete the project_id all together (no project), you could
use unset().
Now, go back, and have a look at your code, check out the logic, and I'm
sure you'll see the mistake(s).
As far as the maintaining session forever thing, I'd highly recommend
it... it's highly insecure (walk away from your computer, someone else has
access to everything)... besides, sessions are a temporary thing by nature,
with garbage cleanouts, etc etc.
If you really wanted to maintain state 'forever', you would have to set a
cookie with the username and password to that person's computer, hence your
website would 'remember them' all the time.
Of course there are plenty of reasons why your shouldn't do this. I guess
the client should be informed of the options here:
1. log in every so-often as needed (if there is lots of activity, the
session probably won't die all day anyway), and have heaps more security
2. log in once only, and have the whole system wide-open forever
I'd pick 1 over 2 anytime.
I'd also provide a logout button with either system, so that people CHOOSE
TO DESTROY THEIR SESSION. Personally, I log-out when I leave my desk, just
in case.
Imagine if you left a session open which disclosed everyone's pay rates in
an office... not good for your career at all :)
Hope this all helps,
Justin French

Yes, it is a forward link to the page, but as mentioned, that page
contains a form with the selection options, and on that form's action
page is where I don't see the values change, so the question should
probably be something like how do I change the value in the session_var
with the newly selected value?
And oh, I almost forgot:
Due to that fact that this type of app doesn't really have a logical end
page, I cannot issue a session_destroy() anywhere logically ( except
using a logout button), but that's not going to ensure that people use it...
I would ideally like to have this app run on an intranet, where people
will most probably have this app open indefinately, and thus I also
battle with my logic of keeping a session alive.

Well, how exactly do you implement the back button? If it is a normal
client-side back, then of course the previous value will be shown. If it
is actually a forward-link to the previous page, then your logic on that
target page is bogus.
By the way, trans-sid is compiled in by default in PHP so should always be
available. And it will fallback to sid mangling only if cookies are
disabled. You would probably be better off just letting php manage this
for you.

Well, I have asked a couple of questions on this list, but they havn't

My situation background is as follow:
I have always written my apps in the following way: register_globals=on,
so I allowed PHP to generate my variables for me on the action page,
and if I cannot use a form to send variables to the next pages, I
added them manually to the url.
So, then I discovered sessions and thought my probelms were solved, only
to discover that it uses cookies by default, and has to have the
--trans-sid option compiled to have PHP handle the app if you don't want
cookies ( like me, don't want cookies at all, or for that matter,
anything that relies on the client's side). So,

Line wrapping... What a concept.
In my PHP XML parsing

I have a db with the following fields: id | month | company | title | name | role | show_company | show_title | show_month sql query is: select * FROM db ORDER BY month DESC; Output gets formatted like: month - company - title name role name role - title name role - company - title name role name role name role The occurrence of the number of fields within each heading is not static. The oldest data sits at the beginning of the db so the order by month desc sorts the output from newest to oldest. Fine so far. Now, as new data gets added to the db sometimes some of it refers to past months. So although the order by month clause will move the new data to the correct month it will not move it into the correct heading (company) and sub_heading (title). I've tried using group by and using multiple fields in the order by but can not get the results I'm looking for, any suggestions? -Brian -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Hide the undefined offset error for the array?
Your default error reporting level must be set different on your Windows
box. If you turn off E_NOTICE warnings on your Windows box it will act
the same as your Linux box.
But, in general, to write E_ALL clean code you would check if each exists
first, or swallow the errors if you know that these indices may not be
present using something like this:

$responders is an array of Responder objects - a Responder object has Email,
LastName, FirstName member variables.
My problem is that although the email is sent on each iteration and reaches
it's intended recipient, I get the Failed to send email message on
every loop!
Anyone know why? mail() is obviously returning false, but the manual says
mail() returns TRUE if the mail was successfully accepted for delivery,
FALSE otherwise. Yet it _must_ have been successfully accepted for
delivery, because the emails always get delivered.
Any help would be appreciated.

Re: [PHP] Good books on sessions
Yes , I agree,But that is exactly where my problem comes in, when I link
the person forward, it DOES NOT take the new value for the project_id,
as it is a form element and it only becomes variable on the action page.
This is where I'm unsure about how to initialize the variable. As
mentioned earlier in my posts, I simply do a
session_register(project_id); on the action page, I DO NOT say
anything like
$_SESSION['project_id'] = 45; or any other form of assignment whatsoever, as I leave
the work to register_globals=on and it's normal expected behaviour. And I think this
is where the problem lies.
It seems I MUST actually do that for things to work??? Unfortunately I cannot test
this yet, as I'm busy with something else, and just trying to get the basic academics
right. I understand the way you are explaining sessions 100%, but when I put that
knowledge to practise, things doesn't seem to work... :( .
I am still to test yours and Rasmus' sugestions and will come back shortly.
Thanks for the help so far.
Justin French wrote:
*shakes head a bit*
I'm not REALLY sure what the problem is here, but let's take a step back.
A session ID is a unique, random number assigned to a user as they kick
around your site.
To maintain state (a session) across multiple pages, you pass the session id
around. This can be done with the URL or cookies. Yes, trans_sid is in
there as well, but all it does is re-write URLs.
No surprises so far.
You then assign variables to the session. If you're using PHP = 4.1, I'd
use $_SESSION['varname'] = value; rather than session_register(), because
it's a lot more logical, and clearer to think through.
Furthermore, the manual tells us NOT to mix use of session_register('var')
and $_SESSION['var'] = 'value'... so, pick a method, and stick to it...
since the $_SESSION array is the new way, I'd be going with it.
So, the first two session vars YOU assign after the user logs in is the
username and password (I wouldn't register the password).
$_SESSION['username'] = justin;
$_SESSION['password'] = secret;
Then a few pages later, they pick an option from a pull-down list, and you
assign another variable to the session:
$_SESSION['project_id'] = 45;
The user clicks through a few more pages, and later wants to work on a
different project, so you link them through (forward) to the options page.
They select a new project from the pull down, so you need to overwrite the
old project_id session var with a new one:
$_SESSION['project_id'] = 74;
Now, when they kick around through pages, they will be doing it under
project_id 74.
If you wanted to delete the project_id all together (no project), you could
use unset().
Now, go back, and have a look at your code, check out the logic, and I'm
sure you'll see the mistake(s).
As far as the maintaining session forever thing, I'd highly recommend
it... it's highly insecure (walk away from your computer, someone else has
access to everything)... besides, sessions are a temporary thing by nature,
with garbage cleanouts, etc etc.
If you really wanted to maintain state 'forever', you would have to set a
cookie with the username and password to that person's computer, hence your
website would 'remember them' all the time.
Of course there are plenty of reasons why your shouldn't do this. I guess
the client should be informed of the options here:
1. log in every so-often as needed (if there is lots of activity, the
session probably won't die all day anyway), and have heaps more security
2. log in once only, and have the whole system wide-open forever
I'd pick 1 over 2 anytime.
I'd also provide a logout button with either system, so that people CHOOSE
TO DESTROY THEIR SESSION. Personally, I log-out when I leave my desk, just
in case.
Imagine if you left a session open which disclosed everyone's pay rates in
an office... not good for your career at all :)
Hope this all helps,
Justin French

I used to work for another hosting company who would just guess new expiration dates for monthly recurring customers who had not submitted a cancellation request but who's cards had expired. As long as the date was past present they would go through. P.S. Save the flames. It was not my idea to guess new expiration dates ;-) Jim Grill Support Web-1 Hosting http://www.web-1hosting.net - Original Message - From: Craig Vincent [EMAIL PROTECTED] To: Laurent Drouet [EMAIL PROTECTED]; PHP List [EMAIL PROTECTED] Sent: Tuesday, July 30, 2002 3:41 AM Subject: RE: [PHP] Credit Card Validation With Expiration Date I'm looking for an algorithm or a free PHP Script which enable me to verify expiration date with a credit card number.

RE: [PHP] searching an array for words starting with 'p'
I don't think there's a builtin that does exactly what you are looking
for, but this will do the trick:
?php
$array = array ( pinaeapple, orange, passionfruit);
$newar = array();
foreach ($array as $val) {
if ($val{0} == p) {
$newar[] = $val;
}
}

[PHP] PHP4 and MS Excel?

Re: [PHP] Re: A somewhat unusual session question...
That last statement was not entirely true. The server does not have to know when someone leaves to clean up. You are right about session.gc_maxlifetime and session.gc_probability. if the maxlifetime is set to 1200 (20 minutes) and the probability is set to 1 that means that one percent of the time there is session activity on the server it will perform the garbage clean up routine. If you set probability to 100 then every time someone refreshed or loaded a page that used sessions php will look through the session data and remove anything that's older than our 20 minute maxlifetime. As for your problem, I do not know what to tell you except that you might look for an alternative to file type sessions. It is true that php will not perform garbage clean up if the path is beyond two dirs up from root. MySQL is a popular alternate choice because it's fast and more secure than any file that is world readable.

if ($throw = close)
PDF_end_page($p);

All I do is put in to var $throw open or close and its not
working; $p is global, what am I doing wrong? Im really having a terrible
time
with scope and php, no calles from PDF seem to want to work inside a

[PHP] Re: Dynamic Web Pages
Hi! Database queries and global variables are not related to each other. It usually just boils down to the following steps 1. Collect data that that's needed for the database query (via $_GET or $_POST) 2. Run the query against the database and store the results in some nice variables (arrays/strings depending on data) 3. Display the results within the page by printing the variables at appropiate places inside your template file (test.php). Obviously the possibilities are endless, but if you want a starting point you could try the following link: http://www.php.net/manual/en/ref.mysql.php (check under Examples) Kindly /lasso ([EMAIL PROTECTED]) Rolando Morales wrote: I would like to have the same page (test.php) have different text in it depending on a database entry. which is easy enough. but I want it to be on the fly. example list would be created on the fly depending on databse entries. which ever entry was picked (lets say STLT) it would open up my template test.php and it would but the STLT info on the page.

Sounds like you didn't call pdf_end_page() before calling your next_page()
