Ok, please forgive my ignorance, but in PHP isn't $_COOKIES the same as
$_SESSION?. I thought it was if the user had cookies turned off (and
even if the user had cookies turned on come to think of it) ... If not
I'm in trouble.
I was always under the impression that $_SESSION vars were passed as

[PHP] Securing areas of a web site with PHP
On my web site there are some areas that I want to make accessible only after a user has logged in (for example when placing an order, etc ...) I have been able to achieve this however I have the following problem: 1- user logs in 2- user goes to restricted area 3- user views pages, orders an item, changes his account settings, etc ... 4- user logs out 5- user is sent to log out page 6- user hits back button ... And here my problems start ... even though the user has logged out, all the "restricted" pages he saw are still cached by his browser and accessible ... I have tried using a script that checks a session variable that indicates if a user is logged in or not and take appropriate action at the start of all "restricted" pages, but that doesn't work since when the user hits the back button, the PHP script is not re-executed, the page is simply loaded from the browser cache. What are some PHP techniques I could use so that a user can no longer access/use pages once he has logged out? Basically I would like to have sort of state machine so I that I can simply check where a user is coming from and his login "state" to decide if a certain page should be presented or not (i.e. you can't get here form there or you can't view that page with your current login status). But it seemed that creating a state machine is not the right way to go about it since hitting the back button pretty much allows a user to circumvent this ... Eventually the web site I will build will actually have many "areas", each needing a separate/different login, (and you can be logged in to multiple "areas" at once) so I would like to be able to generalize this problem and understand how I can use PHP to implement the needed functionality. Just as a simple example, once a user has placed an order, he should not be able to go back to the "order placing/processing" pages ... Any tips, hints, or pointers to tutorials are appreciated!

[PHP] PostgreSQL/PHP: transactions: how-to abstract out?
Hi. I thought I had abstracted out the SQL querying part of my code out,
just to find out today that it doesn't work when it comes to
transactions. I had come up with this code:
function sql_query($sql) {
$conn = pg_connect("dbname=JC user=postgres");
$res = pg_exec($conn, $sql);
if (!$res) {
echo "CONNECTION: could not execute query ($sql)";
die;
}
else return $res;
}
I had transactions in my code implemented like this:
$sql = "BEGIN";
sql_query($sql);
[some sql that should be in a transaction ...]
$sql = "COMMIT";
sql_query($sql);
This doesn't work. Now that I look at my code I clearly see why. All sql
queries are executed using a new Postgres connection, hence the use of
BEGIN/COMMIT as I was using them have no effect.
Can someone recommend a way to abstract out my DB layer while still
being able to use transactions?
I was thinking of using the same function but if the incoming query
contained the word BEGIN, saving that and all future queries in a
session var and when the COMMIT comes in executing all the saved queries
as one (i.e. "BEGIN;[];COMMIT"). One drawback is that all queries
will be written out to disk (as session vars) and that will slow things
down. Another drawback is that I have to abort if not COMMIT comes in.
And a few more drawbacks ...
I was also thinking about maybe the $sql a GLOBAL or first building up
my query as as long string ("BEGIN;[];COMMIT") and *then* sending it
to my sql_query() function.
The last two seem easier to implement, safer, and more efficient but
they don't seem "elegant" because I haven't abstracted out the fact that
I want a transaction. Whenever I write an SQL query I have to think
"does this need to be in a transaction" and then use a different coding
technique depending on the answer. And if the future something that
didn't need to be in a transaction now needs to be in a transaction I
have to revisit my code and change the code.
I'm sure someone out there must have thought about this and come up with
an elegant solution and way of abstracting out the DB layer from PHP.
Can anyone share their solution with me or give me some pointers to
reference material?
Thanks,
Jc

You're right! I did some more testing and the problem is with my testing

Any idea why connection_status() returns 0 when it should return 2??
My code:
set_time_limit(2);

require_once("db_functions/sql_query.inc");
$sql = "BEGIN;";
$res = sql_query($sql);
$sql = "insert into test(test) values('testing 4');";
$res = sql_query($sql);
//This will cause the script to time out
$i = 0;

$sql = "COMMIT;";
$res = sql_query($sql);
function timed_out() {
$status = connection_status();
if ($status == 2) {

}
else echo "no time out. Connection status is $status ";

[PHP] Re: PostgreSQL/PHP: transactions: how-to abstract out?
To all who replied to my initial question ... I actually did *not* have problems with transactions in the way I first implemented my abstraction layer. In the case of PHP "If a second call is made to pg_connect() with the same connection_string, no new connection will be established, but instead, the connection resource of the already opened connection will be returned." The bug was in my transaction testing code. I was forcing PHP to time out to check weather the transaction went through or not. In the script I was catching the time-out but it so happens that there is a bug in PHP when it comes to catching connection time outs using the connection_status() function ...

Rasmus Lerdorf wrote: No, you didn't understand correctly. I specifically said the thread safety issues were in 3rd party libraries and not in PHP. Sorry, I thought by 3rd party libraries you meant libraries that PHP is dependent upon. Do you mean libraries used by PHP or Apache. And if these are libraries used by PHP, do you mean library that as in the multi-byte library (i.e. libraries that add functionality to PHP), or do you mean C libraries used when compiling PHP. Why exactly are you asking? Is there some feature in Apache2 that you need that is not available in Apache-1.3? I don't want to move from Apache 1-3 to Apache. I just keep hearing that PHP is not ready for Apache2 yet and I wanted to educate myself as to why. I don't like just being told something and not understanding the reason behind the answer. So this boils down to Apache2 using threads and PHP not being thread-safe? And the reason that PHP is not thread-safe is that some 3rd party libraries PHP used are not thread-safe. Now the only two questions I have left are : #1 what those libraries are used for. I.e. are they part of PHP or libraries that are used to compile PHP? If they are libraries used to compile PHP, I would assume that Apache2 must have faced similar issues when going from a forking model to a threaded model? #2 Is there progress being made towards having PHP work with Apache2.

[PHP] Re: mcrypt installation problems
I fixed my problem. For archive purposes (as of PHP 4.3.0), to install mcrypt support you only need to install libmcrypt. No need for mcrypt, or mhash ... forget anything else you might read. The installation problem I had was indeed a bug in PHP which I am happy to say is fixed in the latest CVS STABLE snapshot.

[PHP] Security Q (persistent in-memory var possib;e?)
I have a PHP application that connects to a DB an retrieves encrypted data from it. The PHP application uses the decryption key to decode the data to so some work with it. Right now the key is hard-coded into the PHP script. I am worried that if someone hacks into my server they will have access to the the encryption key and can then use it to decode the encrypted data that is on my DB. Is there any way for me to remove the decryption key from the script itself and make it as inaccessible as possible? One solution that I was joping would be possible would be to a (super)global variable that is put into RAM once the web server is started. That way the key is not lying around anywhere. Is there anyway for me to either make a either $_SERVER var for apache (say in the httpd.conf file which I could delete after starting the server or in the source code?) or of creating my own superglobal for PHP (and then I delete the source code)?

[PHP] http->https->http redirection causes browser to show alert dialog
I have a login page with a form where users enter there login and
password. The form's action is "https://mysite.com/login.php";.
login.php authenticates the user and if the authentication is successful
it ends with a:
header("Location: http://mysite.com/welcome.html?a=b&c=etc...";);
The problem I am facing is that the flow of event is:
http -> https -> http
and this causes IE and Netscape to put up an alert box telling
users that they are leaving a secured site.
The IE messages is:
"You are about to be redirected to a connection that is not secure. The
information you are sending to the current site might be retransmitted
to a non-secure site. Do you wish to continue?"
I only want to use HTTPS for the parts of my web site that actually need
it and nothing else. The way I have things set up now I receive the
data through HTTPS, use it, and then put the user back on a "regular"
HTTP connection since I don't need https anymore. But I get browsers
throwing up these warnings
Is there a way around this? The messages are annoying at best and
probably scary to users ...
Thanks,
Jc

[PHP] 4.3.3RC download mirror sites?
I am trying to download php-4.3.3RC2 from the PHP site but my connection keeps timing out even before the download starts. I'm guessing the main server is too busy? Does anyone know of any mirror sites? Thanks, Jean-Christian Imbeault -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] how to use array_map() with a class callback function?
I'd like to use array map with the callback function being a static
function in a class. How can I do that?
I have tried:
class Maker {
function sGetNameId($a) {
return 1;
}
}
array_map("Maker::sGetNameId", array("1") )
But I get this error:
array_map(): The first argument, 'Maker::sGetNameId', should be either
NULL or a valid callback
Is it possible to use class functions as callback functions?
Thanks,
Jean-Christian Imbeault

Thanks! That did it.
Now if only PHP could treat class functions first-class citizens instead
of having making us jump through hoops ;)

[PHP] OO function overloading?
Is it possible to overload a function is a class. I would like to have
the same function defined differently depending on the number of
arguments passed in. For example:
function foo() {}
function foo($a) {}
function foo($a, $b) ()
I know I could do it with:
function foo($a = "", $b = "") {}
But that is such an ugly hack ...
Thanks,
