RE: [PHP] session_start() times and resets?
See session.gc_maxlifetime in php.ini. The session timer is based on the session file access (or modified?) timestamp.

Hi - I'm a TOTAL php NEWBIE - my 1st bit of code!!!.
Basically the input form page has 17 sets of radio buttons, each
representing one game with 2 options - team 1 and team 2.
What I want to
do
is a better way of checking each radio button value instead
of using an if
statement for each. This code doesn't really work - it
finds that vars
ALWAYS exist.
IE:
INPUT NAME=Game1 VALUE=1Chicago
INPUT NAME=Game1 VALUE=2whatever
INPUT NAME=Game2 VALUE=3Minny
INPUT NAME=Game2 VALUE=1Nobody
Code above is processed by the following code:
for ($GameIdx = 1; $GameIdx = 17; $GameIdx++) {
/* instead hardcoding each radio button name - just do it
programmatically
by concatenating / creating the name */
$frmGame = Game + $GameIdx;
if ($frmGame) {
/* U want to check if the length is 5 or 6 bytes because
it could be
game1 or game14 */
$Length = strlen($frmGame);
if ($Length == 5) {
$GetNumber = 1;
}
else {
$GetNumber = 2;
}
$GameID = intval(substr($frmGame, $Length - $GetNumber,
$GetNumber));
print Game --- $GameIdx - $frmGame - $GetNumber - $GameID BR;
if ($GameID == $GameIdx) {
print Yeah Match - $GameID = $GameIdx BR;
/* OK, here is where U want to do the actual insert */
}
} /* $frmGame endif */

RE: [PHP] Project Suggestions
Things I want to do:
- convert this site into a dynamic one, where I can very easily
change the layout of things whenever it comes time to revamp
the site into a new design.
I have not worked with any of the templating systems, but here is a
home-grown one. Separate the page HTML into 3 pieces. Two of the pieces form
the shell, which is the HTML that is constant across groups of pages. The
third piece is the HTML that varies with each page. Build the two shell
files so that they form an empty td, into which the dynamic piece goes:
?
include(htmlShellHead.inc);
buildCurrentPage(); // or another include()
include(htmlShellFoot.inc);
?
Then, if you need to add a right-hand sidebar, for example, you just edit
the shell files, and all the pages using that shell get updated at once.
Simple way to update the look and feel across the whole site.
- insert all the products, their prices and related data into
a database (which would tie in with the above item, maybe by
means of functions, say, 'function
show_product('inkjet_prints')'
Sounds good.
- make it so that those responsible for price changes can make
their own changes to the database, so I don't have to deal with
it every time.
Making your own forms is probably best. We have done this with Java applets,
which may be overkill for you. The main thing to think about here is
authentication: making sure people can access only their own data and nobody
else's. Also, make sure everyone involved shares a clear idea of who bears
responsibility for update mistakes. If the user has the ability to change
their data, they have the ability to screw it up. Make a clear oversight
plan: how much reviewing of their changes you will do before the changes go
live, etc.
Good luck!

RE: [PHP] Getting my head around nulls.
And remember 0 as a number is as important as any other number. I wish the rest of the world saw it that way! But not so... You may want to look at MySQL's IS_NULL function for retrieving data. Other than that, I don't have any good advice. It seems that if you retrieve a NULL from the database and try to assign it to a PHP variable, that variable gets destroyed. AFAIK, yes, you need a bunch of data checks, both putting data in and pulling it back out. Kirk -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, September 24, 2001 8:59 AM To: [EMAIL PROTECTED] Subject: [PHP] Getting my head around nulls. First recap (been doing RDBMS stuff for over 10 years so reckon this is correct). Nulls and blank are NOT the same in RDBMS (in fact there are actually several types of nulls). MySQL implements this correctly (Unlike Oracle which treats null and blank the same). Up to now I am OK but when it comes to codeing in PHP I am not to sure about best practice. The app I am working on for number datatypes inserts 0 if no data is entered in form. I can see why, I am inserting a blank into the database and MySQL goes (Hang on this is a number fields and as you are not inserting NULL you obviously mean zero). So I guess I need to do some conditional stuff so the blanks are not actually inserted or put null into the PHP variable and insert this (Can PHP vars be null but exist?). Or is their another option? The second half of the issue is getting data from the database. I added a couple of columns to database but then I tried to retrieve them as $row[index]. I got a variable x douse not exist error. This really through me until I realised it was because the value in the database was null and it kind of makes sense not to create the var for nulls (although it makes coding a pig). So again, it seems I need to do a lot of isset() stuff which is going to be a pain. Any other insight. Nulls with varchar/char types are not so much of a problem as long as you don't mind all fields in the database being blank rather than null after you first insert data into them.

RE: [PHP] Can I rely on session.gc_maxlifetime?
So, no matter if the user is still working, the session will be destroyed. I mean session.gc_maxlifetime isn't session.gc_maxIDLEtime? Every time the user requests a page in an application using sessions, the session file's access time gets updated. The garbage collection routine looks at that access time. If the file hasn't been accessed less than gc_maxlifetime seconds ago, the gc routine deletes the session file. Another factor comes into play, tho, that is session.gc_probability. This sets how often the gc routine is launched. The default value is 1%, which means that on 1 of every 100 page requests the gc routine launches. So, if the server is not getting many hits, it can be a long time before the gc routine launches, so the session file can hang around longer than gc_maxlifetime.

That has been my experience: if a bookmark contains the session ID, PHP will re-use the old session file if it still exists, but if the old file has been cleaned up, then PHP will create a new session using the old ID in the bookmark.

Any additional help appreciated. I might be able to help if you have some more precise questions, but basically there are two ways LDAP can be used. You can either use it as a data store or you can have LDAP make the authentication decision for you. If you want the user to supply username and password, the authentication can be done as follows: As data store: Hopefully the passwords are stored encrypted. Then there are two ways. If the password is stored encrypted with some unknown salt where the salt is stored together with the password (like the traditional UNIX way), your PHP script retrieves the encrypted password from LDAP, checks the salt, encrypts the user supplied password using the salt, and compare the two. If you don't use a salt you can encrypt the password from the user and just do an ldap_compare to check that it's the same as in the LDAP server. You get better security by not allowing people to read the encrypted passwords from LDAP. To store passwords encrypted in LDAP, SHA1 might be a good choice, PHP has this. As decision maker: You can simply bind to the server on behalf of the user, you use the user supplied username and password as arguments to ldap_bind(). If the bind succeeds, you let the user access your stuff. In this case you should consider using SSL/TLS for talking to the server. There are other ways to authenticate with LDAP, RFC 2829 gives a good overview. You can find it at for instance http://www.ietf.org/rfc/rfc2829.txt I could go into more detail, but to write a complete general overview would be a lot of work.

[PHP] Security question: getenv()
Happy Friday! I don't know anything about the innards of the PHP/Apache relationship. I am wondering if there is a security advantage to using the getenv() function to access an environment variable, instead of using the $HTTP_SERVER_VARS array, or, if register_globals is on, the global version of the variable. Using $SERVER_NAME as an example, and assuming register_globals is on, if $foo = gentenv(SERVER_NAME); $bar = $HTTP_SERVER_VARS[SERVER_NAME]; are $foo, $bar and $SERVER_NAME guaranteed to have the same value? Can a cracker poison one of these but not the other? Does getenv() get the value from Apache or PHP's namespace? You know what I'm getting at, right? ;) TIA Happy Friday!

Hi Mike and Jim,

simple as this not working in somefile.php:

I've looked over every single line in my php.ini, the only
thing changed (checked with diff) is adding the debugger info
for DBG. That doesn't do it either, I replaced it with my
original from PHP4.0.2, no go either.

$PHP_SELF still works fine, just make sure that
register_globals is on.
Also, don't forget that you must define global $PHP_SELF if
you need to
use it within a function, like so:
function foo() {
global $PHP_SELF;
}

RE: [PHP] register_globals odd behaviour?
I just come across and odd behaviour with the register_globals and session handling. The problem is that when I set the register globals to on I cannot access the session_variables through the associative array HTTP_SESSION_VARS. The manual says explicitly that with track_vars and register_globals both on the array and the vars will point to the same. I believe this was a bug in all versions prior to 4.0.6, globals and $HTTP_SESSION_VARS did *not* reference the same value while on the current page, in spite of what the manual says. So, either upgrade to 4.0.6, or use the global version of session variables rather than the $HTTP_SESSION_VARS array.

OK, the session_is_registered() thing is correct.
It seems like the gist of the problems is that different
pages can't seem to
modify the same session variables.
This is definitely not the case. Two things to try:
1. In page2, put some logic around the session_register(FailedLogins);,
otherwise you re-register on every visit. I don't think this affects the
variable's value, but it is definitely wasted cycles.
2. If register_globals is set to on in php.ini, and you are using a PHP
version earlier than 4.0.6, then the code below probably won't work. If this
is the case, just use the global variable, $FailedLogins, instead of

Subject: [PHP] chicken and egg problem with SID
I have a multi page sequence of input forms tied to a session. It
works perfectly with cookies. But I also want to make it work without
cookies, using:
php_value session.use_cookies 0
php_value session.use_trans_sid 1
in my .htaccess file, to use the SID support provided by PHP.
When testing this, I see that the SID works with all pages except the
first. But because the first page has no SID passed to it in the URL,
the first instance of:
session_start();
creates a new session every time you refresh the first page with the
browser. And that is the problem. I only want one session to be
created, no matter how many times the user hits refresh on the first
page.
So then I tried setting the session id myself, hard coding it to some
arbitrary value like:
?
session_id('625d282694214b0459cebe28');
session_start();
?
and that solves the multiple session problem; only one session is
created, no matter how many times you hit refresh on the first page.
Yay!
But that still leaves a chicken and egg problem to solve:
I can generate some random value to be used for the session_id, but I
can't think of a good way to store it for use on the first page.
Since the first page does not get the SID in the URL, I need to set
the session_id before calling session_start. But that means I don't
have any session where I can store my random value, for recalling it
later, on the next page refresh.
Ack! I only need some simple way to store the SID value I generate,
before the page is loaded a second time.
I thought of using a CGI to dynamically generate all the PHP and HTML
for page 1, and also have the CGI put a random session_id value right
into the page source itself, just like I did when testing. I suppose
that would work, but it seems like there should be an easier way.
Maybe there is some obvious solution, but it is not obvious to me at
the moment.
Has anyone else solved this problem, with a better method?

RE: [PHP] Session Headaches
I am using php 4.0.6 and i would rather not use global variables. I hear ya. After playing around with this, your approach works if register_globals is set to off (I did this with an .htaccess file). I'm surprised by this. It appears that the global version of a variable still overwrites the HTTP_SESSION_VARS version when the script ends and the data is stored to the session file, in spite of the change in this area in 4.0.6. This is not the behavior I expected with this bug fix, but it appears to be the case. Since your code never sets the global version of $FailedLogins, nothing gets stored in the session. Unless I'm missing something, it looks like register_globals needs to be off to use session variables the way your code does. In case you haven't done this before, create .htaccess with this line: php_flag register_globals off All for me on this day. Good luck!

RE: [PHP] Script timeout
Why timeout at 300s instead of the 30s or the 12000s which are the only two values reported? Looks like some HTTP timeout, i.e. either Apache or the browser is getting bored. Try outputting something from time to time. Can anybody point me to information on all the possible HTTP timeouts there are (Apache, browser, ???), or care to discuss it here? We occasionally see timeouts that are not due to PHP, and I'm wondering where they are coming from.

i have written a login page for a members area on my site -

require_once(backend.php);
if (!$userid || !$password) {
include(loginform.php);
exit;
}
else {

if ($login != 2) {

it uses authlib to authorise the user and then include a
different pasge if
they are logged in...fairly simple so far..
approx 50% of the time the user cannot log in straight
away... the page just
reloads and you get the blank entry fields again.

RE: [PHP] Session not timing outafter 180 minutes
Everything is pretty much set to default vaules. I can leave the browser open and come back 12+ hours later and the session is still active. Why?? There is another setting which affects this, gc_probability. This setting determines how often the garbage collection routine runs (that kills off old sessions). The default is 1, which means the gc runs on one out of every 100 hundred requests. So, if the server is not getting alot of requests, the gc routine doesn't run very often, and sessions last longer than the timeout value.

Tim, thanks for the tip. I had heard of this behavior before, but never
witnessed it. Today I wrote a test form with 1 text field and 1 submit, and
it did do this: when I submitted via return, the submit field was not
posted. However, when I added a second text field to the form, the submit
did get posted. I was careful that the focus was still in the text field,
and not on the button, when I hit return.

On all subsequent requests, the cookie is used to route the request to the original server. 2. Haven't done this, but you could also put the session data in a database. See the php.ini file for the session handler setting. 3. I believe I read that there is a way to save the session files to a drive that is mountable by all the cluster servers.

so if a particular form button is clicked a different process will occcur. well what happens if i press return to enter my form submission? nothing is set! so the processing file does nothing This has been pointed out from time to time on this list. It is a fact: if the user submits a form with the return key, a submit button value may, or may not, get posted. So don't rely on the submit button. 3 possibilities: 1. If one of the buttons can be considered the default action, then write your logic as: if(non-default button) do non-default stuff else do default stuff If no button value gets passed, the default stuff gets done. 2. Again, if one button is default, put a HIDDEN field with the same name and value as the default submit button just *before* the non-default submit button. The HIDDEN will always get posted, but will get overwritten if the user clicks the non-default button. 3. Write your logic as: if(non-default button) do non-default stuff elseif(default button) do default stuff else meta refresh redirect back to original page In the redirect, put a message asking the user to click a button, with a pause of 5 seconds or so.

RE: [PHP] session_unset session_destroy being called outside of logic.
Several comments, Jason. session_destroy() terminates the session, which cannot be started up again until the browser is restarted... Yes, session_destroy removes the session file that stores the values of session variables between pages. Once gone, it cannot be accessed again under any circumstances. sooo... I just removed session_destroy, and settled for using sess_unset() to log out of a session. using this method the session is still open, and the session variables are still registered. since they are still registered, they can still be used on the chance that I log in again, correct? session_unset clears the values of all session variables in memory while on the current page. If the variables are not re-assigned before the page ends, all the variables in the session file get blanked out when the page ends. case logout: session_unset(); session_destroy(); $AuthErr = FONT SIZE=-1 COLOR=redSession Terminated/FONT; break; What is happening, is after the user authenticates and logs in, everything looks good, but whenever the user follows any link, the session gets unset and destroyed. Have you verified that the session file actually disappears? This sounds more like the session ID is not getting passed along to the next page, so that PHP is not aware that a session already exists (and so starts a new one). The session ID is usually passed between pages using a cookie. The ID is what allows PHP to find the correct session file and restore the session variable values.

My guess is one server has register_globals on, the other has
register_globals off. Try this change in your code: instead of assigning a
value to $HTTP_SESSION_VARS[toto], instead assign a value to $toto. You
will then see a value for $toto in the echo session_encode().
$HTTP_SESSION_VARS[toto] and $toto are *not* the same variables while on
the current page.
The other way to approach it is to use an .htaccess file to turn
register_globals off but leave your code as it is below. Again, you will
then see a value for $toto in the echo session_encode().

I have max_execution_time set to 300 seconds in php.ini. However, users report to me that the PHP script does not always time-out after 300 seconds, it can be much longer than that. So, my question at last: will PHP wait to display the time-out message until after the other process completes?

RE: [PHP] verify phone number
One way:
$phone = ereg_replace([^0-9], , $phone);
if(!ereg(^[0-9]{10}$,$phoneHome)) {
echo error;
}
You could also check the string length after removing all non-numbers.

Before we get too carried away here :), what didn't work with your original
solution? I would have guessed that it would work. What was the error?
But, here's some more with the loop, definitely not tested:
reset($HTTP_POST_VARS);
while(list($key, $val) = each($HTTP_POST_VARS)) {
if(is_array($val)) {
if(count($val) 0) {
reset($val);
while(list($key2,$val2)=each($val)) {
$GLOBALS[$key][$key2] = $val2;
}

Ok, I see where that's going.
I actually was a bit off in my first posting.
The form field names are a multi-dimesional array. The goal it to make
writing all of the info to the db a breeze.
ie- name=cust[personal][phone]
and name=cust[history][interests]
etc etc
lets also say
$cust[history][interests] = tv;
The reasoning behind it is the data does not need to be stored in a
consistent or usable (just readable) manner. so... say
history is a table,
and has a column name details.
I would cycle through the array two levels deep on the first
associative
history, i suppose with nested while(list = each).
The two values I want to return from that array would be the
2nd associative
key name and the value, in this case interests and tv.
SO... back on track... how would i utilize that loop below to get my
multi-dimesion form variables into a session. Once I get it
into a session I
think I can break it up no problem.
Thanks.

RE: [PHP] load balancing...
We are doing it here, although I am not involved in the server setup so I can't give you much help. I guess the main thing is setting up the session storage mechanism. If you use session files, then the load balancer needs to add a cookie so that requests in multi-page applications always go to the same server (so that the session file can be found). The alternative is to use a database for session storage. Other than that, it is working well for us. We are using an F5 load balancer with Apache/1.3.14, Linux, and PHP/4.0.4pl1.

Just to add a couple details. On the first page request, PHP sets the constant SID as well as the cookie. If the user has cookies disabled, then SID is also set on all following page requests. If cookies are enabled, then the cookie PHPSESSID (if you stick with the default name) exists on all following page requests. Kirk -Original Message- From: Adaran (Marc E.

This is a simple yet fundamental programming question I am
hoping somebody will
have the patience to explain...
I have a mysql database with the email field as the key.
Before inserting an
new record to it I want to check if there is already a record
with that e-mail.
This I can do fine. But this script needs to also handle
delete requests,
which I can also do fine, but I need to code for the instance
that there is a
delete request for an e-mail record that does not exist. How
can I figure out
if after my 'while' loop is finished checking the database it
has not found a
match (so i can inform the requester as such)?
Here's the code I have so far...
$email_check_query = SELECT email FROM
$tablename WHERE email = '$email';
$email_check_result = mysql_query($email_check_query);
while($email_query_data =
mysql_fetch_array($email_check_result)) {
$db_email = $email_query_data[email];
//if match, it's an update or delete
if ($email==$db_email) {
if ($op==delete) {
$action=del;
echo delete
requestbr;
}
else {
$action = upd;
echo update
requestbr;
}
}
} //end while loop

Add an exit(); immediately following all the header() calls. Hitting a

different searches
based on what engine was selected. One of these searches is
restricted, and
runs a function that checks for a cookie. If the user has no
cookie, they
are redirected to a login page.
I've used echo tests to make sure the function is being run
correctly, that
I don't have a cookie, etc, and it all checks out. I
*SHOULD* be redirected
to a login page, but I am not.
if ($fromwhere == ARCHIVES) {

I tried putting the check_cookie statement in and outside of
the switch
statement, but both places perform the cookie check, fail it,
but don't
redirect me, and continue to allow me to search? What is
