This might be possible to do with some client-side javascript. I think that eTrade and all of those sites are using an AJAX paradigm and so the client is periodically pushing requests onto the server (but just for the information that needs to be updated). Among other things I'm sure that users would be submitting the session ID that they have and eTrade can track if the browser session is still alive by doing this. However, all of this would be something to ask on a JS list instead of here. :-) Also remember that not all users will enable JS so you need to have backup functionality (i.e. rely on the timeout) so you will never have 100% accuracy, but the method described above will improve your accuracy (at the cost of extra HTTP connections) ... by your statements, you're pretty much saying that the only approach one has > to this issue is to utilize some sort of timeout function, and if you > don't > detect user activity after your timeout, then mark the user as no longer > being active, and proceed accordingly. this apporach doesn't allow an app > to > immediately know when a user has killed the browser. > > so, the question might be, how does one detect when a user has killed a > session/left your app? The timeout method is still the main way to do it... but with the addition of the AJAX methods you can have the client machine *push* updates into your user session. Once you've determined that the client is enabling JS then it is pretty safe to assume they will keep JS enabled for the life of the browser session. So when your site stops getting pings from the client you could kill their session. All of this said... unless you're using AJAX throughout the entire sit already I wouldn't mess around with it. IMHO it takes a lot of extra coding and the added benefit for something like improved user count isn't going to offset the costs of coding and extra HTTP connections when it goes live.
Re: [PHP] trying to figure out the best/efficient way to tell who is logged into a site..
Close: You mix both of these ideas. Create a custom session handler. This handler creates user entries in a database. Then when you want to know how many are online you do a count on the number of user entries in the table. Play around with different gc_probability values to tune the efficiency.

Re: [PHP] Unique user?
I'm going to agree with Jay... most users are lazy enough that if you just require them to have a user account then that will suffice. Since this is only for a joke site that would be my suggestion as well. However, if you really, really wanted to identify remote *computers* then you can try tracking the clock skew of the client which is making that request. If you're interested then google for "clock skew tracking" and you should get some hits. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Custom session handling - bad or good idea?
This can be a fine way to go, given that you have a specific reason to do so that is not easily handled by using session_set_save_handler. The most common session handler in use (besides the default handler) is a DB session handler. You could write this handler in C and it would possibly be worth the effort. Caching DB connections in a shared module could give you a nice performance boost (although I have no idea how stable a setup like that would be, usual caveats about multi-threaded servers would apply). Hope this helps. On 8/18/05, GamblerZG <[EMAIL PROTECTED]> wrote: > I'm not speaking about "session_set_save_handler", I'm considering > writing session handler from scratch. Is it a bad idea?

Re: [PHP] Register globals and ini_set
Since you mention the PHP version was old (4.1) then I have to ask: were you using the $_SESSION array all along or were you using session_register to register session variables? Although you probably aren't since that would be rather easy to debug. The script in which your global_variable was set makes absolutely no difference. PHP is just looking for the SID someplace anyways (whether that's COOKIE, GET or POST) and then it goes and retrieves that session that matches that SID. OK... when you say that it fails sporadically, what do you mean exactly? Probably, based on what you've just said, you're somehow assigning into your $_SESSION variables through the use of global variables that have the same name as your $_SESSION indexes. http://php.net/manual/en/ref.session.php#ini.session.bug-compat-42 -- NEW? | http://www.catb.org/~esr/faqs/smart-questions.html STFA | http://marc.theaimsgroup.com/?l=php-general&w=2 STFM | http://php.net/manual/en/index.php STFW | http://www.google.com/search?q=php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

ini_set() just doesn't make sense for that directive. register_globals
takes the input data from HTTP requests and sets them in the symbol
table before any of your PHP code gets parsed. PHP has already done the
work. Doesn't seem too terribly efficient to just throw all of that
away on every script invocation, now does it?
But what you *can* do, is to ini_get('register_globals') and have your
script act accordingly. You could for example extract() your $_GET and
$_POST variables.

You'll have to shove all your PHP knowledge over to one side of your brain, cram all the new stuff into the other half of your brain, and then compare/contrast. Then, for real fun, try to learn something totally whacked-out different like Lisp, Scheme, Forth, Logo, or even (blech) COBOL. This will require even more compartmentalization in your brain-space, and some serious deep thinking on what makes a program tick. Only after you really "get it" in a totally different programming paradigm do you achieve that deep comprehension of Programming with a capital P. Hmmm how does declensional based programming sound? Remember back when our ParrotHeadPoster was alive and squawking and ready to flap his wings right out into the news server? Well doing some searching for text classifiers led me to this really funky, weird, unusual... twisted... programming tool. The program is called crm114. "It's not ugly like Perl; it's a whole different *kind* of ugly." I still am not an expert with this program (hell, the development is finally getting to where it can use autoconf), but it fits in really well as a new / active tool that does everything different. And I mean almost everything. Everything is a regex. The default regex engine is called TRE (which supports approximate matches). The language is declensional instead of parameterized. For the most part the order that you use for your arguments just don't matter. Variables look like :*:yourvariable: Releases don't follow the typical naming convention; instead, people get blamed for releases. crm114-20050628.BlameCochrane is the new release that just came out and it is the "CRM114 Galactica Buzzphrase Compliant Version". It makes use of the new hyperspatial classification... just read the manual on it, ok?!?! At least one similarity to PHP though: it makes use of a JIT compiler. In short, it's a useful and interesting utility. Not just because it can sort your spam / nonspam email with greater than 99% accuracy... but because you can adapt it to other tasks by writing your own crm filters. This is no simple task (I'm still learning how to use it!), but this is mostly because the way of doing things is just different. The whole thing is like a computer science project gone mad, but at the same time it's actually very useful for something. For those that are interested, grab the new version released today: http://crm114.sourceforge.net/ H. That came out kinda stronger than I meant it... I mean, sure, the guy who learns C, and knows only C, and codes C all day is a Programmer, and I'm not knocking that. But there's this sort of "hole" in a guy like that, and while it doesn't "hurt" them or make them less a Programmer, it's there, and it's just not the same as a guy who actually groks something as bass-ackwards (that's a compliment) as Lisp as well as they do C.

My idea is a great one and it's going to make millions. Now since I'm the one that had the idea I think it's pretty easy for me to go find 3 friends of mine (people that I know/trust/live close to me) that have the requisite skills. After all, it's not like most programmers go hanging out with Hollywood celebrities. ;) If I really believed that my idea was so hot then I probably wouldn't be waiting around for someone on this mailing list, I'd just get started doing it. Back about two years ago I was subscribed to this newsgroup with my email address from college. Back then I was just doing what I do now... answering PHP questions while I work. Except that I answered a lot more questions then because, well, I was in school still. :) I don't remember exactly how many I answered, but you can check out the marcives if you really want. Anyhow, after doing this for about a year I apparently caught someone's attention. I received an email from telling me that he had capital to give me if I had an idea that I wanted to develop. I politely declined, but I told him I would get back to him if a superb idea came my way... I have always felt that getting the financing is the easy part. Besides, if your goal is to get $millions in funding then you're looking at it all wrong. The goal is to make profit... and loads of it. If it just so happens that you need a lot of funding to make that happen, then you can go get it. If you have killer idea(s), then you are better off mocking up a prototype and networking with some people that can get you financing. You always have to make a profit. You always have to make a profit.

Re: [PHP] Re: security question...??
This was an interesting topic when it started, but this is getting way out of the realm of PHP and you are in danger of your messages going my /dev/null. I understand your concerns about application security being all-encompassing, but there have been a lot of good suggestions on how to overcome some of these problems already. If you are hell bent on checking browser integrity then this is what you do: 1. Download every version of IE, Fire(fox|bird|???), Opera, Konqueror, Safari, Links, Lynx, Mosaic, Netscape Navigator, mobile phone browsers, PDA browsers, etc. that has ever existed. These have to be the "trusted" binary versions of those applications for every platform on which they have been built. 2. Run a checksum program on each of the binaries and store the checksums in a database. This checksum algorithm needs to be one that you trust. 3. Require each user to create a secure connection with your server (however you want to do that). 4. After the connection is created, get the user to upload the executable they are using to access your server. 5. Checksum the upload and look for the matching hash. The steps outlined above do very little if anything to enhance security, but it is a way to check for integrity of a plain vanilla installation. Then again if you really, really wanted to be accurate you would also need to download and hash all possible combinations of 3rd party add-ons with each browser, for each operating system, and... Do you see what a difficult task this is? And do you think the average user is actually going to do anything like what I've described above? It's tough enough to just get visitors to accept cookies. The benefits of going through the exercise you're describing are nowhere even close to the costs involved (costs meaning the time involved for the server, the client, the web developers, and the end users as well as bandwidth usage). There are other ways to increase security that are more cost effective than what you're suggesting. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

In core.class.php I have my generic special html methods and my db

user.class.php should be able to access methods/attributes of

http://php.net/manual/en/function.include.php
So if user.class.php include()'s core.class.php then you should have the
class definition (for methods) as well as any objects that were created.
in core.class.php. In other words all variables get imported into the
current scope in the calling file.
I'm running PHP 5.0.4 on Windows
//core.class.php
class core {
var $db;
Is this actually var? Did you possibly call this private / protected?
Var == Public, so the db property of any "core" class should be available.
function core(){
//initialize db connection (works from here)
}
//Other methods
}
//system.class.php
include "../../inc/core.class.php";
Note that relative paths can cause problems when you switch the current
working directory. This likely isn't a problem for this particular
issue you're having, but it's a gotcha for future work. What I do for
relative includes is something like:
include dirname(__FILE__) . "../../inc/core.class.php";
class system extends core {
function system(){
/** See note below */
$this->core();
}
}
//user.class.php
include "system.class.php";
class user extends system{
function user(){
//$this->db cannot be used here
What exactly do you mean by cannot be used... do you mean that you don't
have access to db? Or perhaps you expect cascading __constructor calls
which PHP does not do by default. Instead you need to call the parent
constructor *explicitly*.
$this->system();
}

As I sit here surrounded by machines (physically and virtually) and
realizing that while I've got most of them on "auto-update" as much as I
can, or I've foisted off the updating on somebody else (for $$$) because I
just don't *WANT* to be a SysAdmin...
I'm still left with a lot of hours I'd have to invest to really be as
"current" as I'd like to be.
Let's take RedHat and other OSes, for example, only because I don't want
this to devolve into the "what version of PHP should I use" thread that
would be a hot button here. [Not that RedHat and or its versions aren't
almost as hot, but...]
No kidding! The way that they switched their codebase was, erm,
interesting to say the least? I looked at Red Hat about 1.5 years ago
and it took me a while to realize that Fedora Core was the free /
development branch of their OS. And the prospect of using a box that
never makes it out of "development" is, um, a reason to invest in Rolaids :)
I've got RedHat 8, RedHat 9, FC2, and FC3 on different machines here and
at client's sites.
Oh, and Win XP Home, just for fun, for testing stupid IE bugs.
I'd love to just move them all to FC3 (4 now?) but it would really be
painful, and a lot more hours than I have available.
Now, the thing is, it's finally gotten to the point where I'm willing to
let the OS authors/maintainers (RedHat) update my box for me, because,
with the current arms race in viruses and whatnot, that's got to be better
than my inability to stay on top of things, even if occasionally it breaks
something that actually worked before.
Yes it's an unfortunate trade off, but not so bad if you Keep It Simple
Stupid (tm). Most of the patches that get released to the wild (i.e.
the stuff that you get if you don't closely watch any internals@ lists)
have been tested for the OBVIOUS problems. It's the edge cases that
cause the most bugs...
My philosophical question is:
Why can't the damn things just have an easy one-click button to go from
major version to major version, or if I'm willing to turn over control of
the OS versioning to RedHat (or whomever) just do it automatically?
Okay, I can accept that for Microsoft and other proprietary software,
that's a non-option, because they WANT to force you to BUY the new
version, though with their new subscription model... Well, let's not get
into THAT argument either. Forget the Windows box.
But that's hard to do with my W2K workstation... with that pompous
sound that blares out of the speakers every time I reboot! ;)
In the past, I've been told that the various pieces of software version
control and tracking means that you need the "clean break" of a major
release to keep sanity in versions.
I think that was true then, but is it really true now?
I would tend to say: yes. Take PHP for example. There are a lot of
Extensions floating out there (mostly in PECL) which rely heavily on
internal function calls / behaviors. So if the maintainers of the PHP
project decide to do something so fundamentally different that it's
likely to break, like, everything... well then every extension out there
needs to be recoded (and tested) or else it's going to break.
There are currently two issues on the PHP internal list that directly
affect this question of yours: Unicode and Module Dependencies.
As we all know (or should know) PHP lacks proper Unicode support. Perl,
Java, and a whole slew of others already have this support, but PHP
("the language of the web?") doesn't. So there is work underway to fix
this in the default distribution (I've heard maybe around PHP 5.5), but
let's face it: this is going to break almost everything. Strings are
the lifeblood of web applications and the addition of Unicode strings is
going to require a lot of extensions to be upgraded. An excellent
summary of this situation can be found here:
http://www.gravitonic.com/downloads/talks/intlphpcon2005/php_unicode.pdf
So clearly our extension authors need to get the word and upgrade their
packages. A lot of them probably will make the changes for PHP 5.5 (or
whatever version Unicode comes out in), but some might not. So if
Redhat comes in and upgrades your version of PHP (even if they're good
enough that they upgrade all of the extensions too!) then you're going
to have an application that doesn't work because your extensions don't
support Unicode.
Now we move on to another discussion on the internals@ list. Someone
(Jani?) mentioned they had started work on a patch for module
dependencies. The proposal is still being worked on, e.g. where do we
do the checking so that PHP startup doesn't slow down too dramatically?
However, if the module lists dependencies properly... and the parent
modules (e.g. PHP core) correctly indicate BC breaks... then we might

Re: [PHP] The "goto" discussion on the Internals List
I agree 100% with Greg's comments for the goto() / ifsetor() discussion on the internals list. As far as speed goes if the dev team knew of ways to improve specific parts of the codebase (while maintaining the rest of the features available in PHP) then I'm confident they would make that change. There was one comment on the internals list that perhaps the documentation should have a big fat red warning label that says "DO NOT USE THIS UNLESS YOU REALLY KNOW WHAT YOU'RE DOING". I guess the developers assume users actually read the manual, but I think this list has proved time and again that end users don't do this. ;) This is especially true for newbies (i.e. the ones most likely to get burned by using goto() all over their code). PHP-dev team: at the moment you are supplying me with 95% of the features that I need with a base installation.

One way that would work for me (and initially it's how I assumed it worked) is for __autoload to be a standard class method like __construct, so that a class would attempt to run its own autoloader before breaking out to the global function namespace. Maybe I'm being dumb, but how can an object's __autoload function get called when the object class definition hasn't been loaded, and that's why you're calling __autoload in the first place... That seems like classic chicken/egg situation to me... that was my first reaction, but then I thought what if the __autoload() function was called when 'any' class needed to be included while running code inside said class... that _might_ actually be useful at any rate the __autoload() issue is still very much undecided :-) I opened up a feature request for this very topic a while back. The __autoload function should just register user-defined functions and store those func names in a stack so that (in turn) each function can require the appropriate file. If the first registered function fails to load the class then __autoload tries the next registered fucntion and so on until all of the registered functions have been tried. At this point if __autoload fails then we E_ERROR out explaining that __autoload could not load the class definition. As far as I can tell this is the cleanest solution that has been provided, but there is some disagreement over some of the details on this approach.

[PHP] Re: array_diff odities
Pablo Gosse wrote:
Howdy folks. I'm running into something strange with array_diff that
I'm hoping someone can shed some light on.
I have two tab-delimited text files, and need to find the lines in the
first that are not in the second, and vice-versa.
There are 794 records in the first, and 724 in the second.
Simple enough, I thought. The following code should work:
$tmpOriginalGradList = file('/path/to/graduate_list_original.txt');
$tmpNewGradList = file('/path/to/graduate_list_new.txt');
$diff1 = array_diff($tmpOriginalGradList, $tmpNewGradList);
$diff2 = array_diff($tmpNewGradList, $tmpOriginalGradList);
I expected that this would set $diff1 to have all elements of
$tmpOriginalGradList that did not exist in $tmpNewGradList, but it
actually contains many elements that exist in both.
The same is true for $diff2, in that many of its elements exist in both
$tmpOriginalGradList and $tmpNewGradList as well.
Since this returns $diff1 as having 253 elements and $diff2 as having
183, it sort of makes sense, since the difference between those two
numbers is 70, which is the difference between the number of lines in
the two files. But the bottom line is that both $diff1 and $diff2
contain elements common to both files, which using array_diff simply
should not be the case.
Hard to say what happened here. If I had to take a guess I might say
that you're getting line wrapping in the middle of 183 different records.
However, when I loop through each file and strip out all the tabs:
And really since you have tab-delimited records you should be exploding
on those tabs in order to get the data set. But because I'm slightly
paranoid I would do it on the entire string of the file.
$str_OriginalGradList =
file_get_contents('/path/to/graduate_list_original.txt');
$ary_OriginalGradList = explode(chr(9), $str_OriginalGradList);
$str_NewGradList = file_get_contents('/path/to/graduate_list_new.txt');
$ary_NewGradList = explode(chr(9), $str_OriginalGradList);
$diff1 = array_diff($ary_OriginalGradList, $ary_NewGradList);
$diff2 = array_diff($ary_NewGradList, $ary_OriginalGradList);
echo '';
var_dump($diff1);
var_dump($diff2);
echo '';
?>
foreach ($tmpOriginalGradList as $k=>$l) {
$tmp = str_replace(chr(9), '', $l);
$tmpOriginalGradList[$k] = $tmp;
}
foreach ($tmpNewGradList as $k=>$l) {
$tmp = str_replace(chr(9), '', $l);
$tmpNewGradList[$k] = $tmp;
}
I get $diff1 as having 75 elements and $diff2 as having 5, which also
sort of makes sense since there numerically there are 70 lines
difference between the two files.
I also manually replaced the tabs and checked about 20 of the elements
in $diff1 and none were found in the new text file, and none of the 5
elements in $diff2 were found in the original text file.
75 / 5 is probably the right mix. Programmatically you can check this
by comparing the diffs with each list.
However, if in the code above I replace the tabs with a space instead of
just stripping them out, then the numbers are again 253 and 183.
I'm inclined to think the second set of results is accurate, since I was
unable to find any of the 20 elements I tested in $diff1 in the new text
file, and none of the elements in $diff2 are in the original text file.
Does anyone have any idea why this is happening? The tab-delimited
files were generated from Excel spreadsheets using the same script, so
there wouldn't be any difference in the formatting of the files.
The sad truth is that this is quite possibly the root cause of your
problem. I have had many many problems caused by MS Excel conversion
to/from other types of data. I don't completely understand the escaping
process in Excel, but double quotes have always been a problem. And
occasionally it seems like Excel just barfs on a tab / comma. Why it
does that is completely beyond me. I can't count the number of times
that I have opened up a comma delimited file in Excel, just *looked* at
the file, saved it, and when I view the source it's been mangled a bit.
Moral of the story: I don't ever use Excel to view tab or comma
delimited types of data unless I have a backup someplace.

Yes there is a chance, but it's small enough that for practical purposes
you can ignore it.

AFAIK yes it is since it takes advantage of memory mapping (where possible).

Not sure.

H... well, file_get_contents() doesn't lock the file so I'm
interested in how you're accomplishing this feat. Perhaps you're
creating a temporary directory (atomic IIRC) for the filename and then
flocking that? I dunno, I hate race conditions.
You might also want to consider the security of the data that goes into
your cache'd $_APP data. Because any file that is created by PHP is
going to be in pretty much the same boat as the default session files
and on a shared server, well...

Session support is now built-in by default, so unless you specifically

build. Although yes, there are several php.ini settings that can modify
cookie behavior:

I won't venture a guess as to why Richard doesn't approve of the centralized approach, but rather just pointing out that if() is logically similar to switch(). Now going back to your original question... one easy to predict problem is that you've forgotten to handle form submission errors. I mean surely you will want to validate the incoming data and do something sensible if the data doesn't match some regular expression(s). If you're really trying to go for a centralized approach then I'd say this validation should be handled through this main script. A simple alternative? Each form has its "target" attribute set to itself. You start out with invalid data. Then when the form POSTs to itself you can validate the incoming data within the same script where the form elements are located. This approach puts all of the business logic for one page *inside the one page*. It makes debugging a lot simpler because, well, if you have a problem with page1.php then you know it lies somewhere in the script page1.php instead of any of the following: - page1.php - controller.php - index.php - page2.php - etc. One of the easiest ways to reduce maintenance is to make it easy to find your bugs.

By default the php.ini settings should enable all PHP scripts to use
$_SERVER variables (i.e. values that are provided by Apache / IIS /
whatever). AFAIK you can limit this by changing the php.ini's
variables_order so that it doesn't include 'E'; or you can use some
combination of safe_mode, safe_mode_allowed_vars and / or
safe_mode_protected_vars to accomplish this as well. The manual says
that all of these except for variables_order are PHP_INI_SYSTEM, so the
only one of these settings that you can possibly change at runtime would be:
Within PHP it is sometimes possible to use getenv() to get the value of
an environment variable. I don't have the time to test this but you
might be able to try:
ini_set('variables_order', 'EGPCS');
$user = getenv('PHP_AUTH_USER');
$pw = getenv('PHP_AUTH_PW');

For my point of view, this should do exactly what I like to do: destroy
the old session data, generate a new one, write them and redirect the
user to next page.
And you're partly right. From the client's point of view it's still the
same session. Why? Because you didn't destroy the cookie as well as
the session data. So you're generating fresh session data, but the id
is the same.
In other words:
- Page1.php
- PHP reaches this session termination code
- session file on hard drive / in DB / whatever for current SID is
destroyed
- $_SESSION still exists! Although this might be ok?...
- execution for Page1.php ends (Header and then exit)
- Page2.php starts
- PHP reads in the session ID from the cookie
- SID is the same as what was used in Page1.php
- However, no session data exists for this SID so PHP starts up a
*new session* with the *old SID*
I remember somehow that there have been problems with SetCookie and
Header("Location: ..") combination. Could this session problem arise due
same reasons?
Sort of. This is what you need:

Subject: [PHP] Tracking what has been changed
Here's the scenario...
I am building a site in which users will be able to create and then
later edit personal information. When they edit their information, I
need to keep track of what was changed so that I can inform via email a
person to approve the changes. Here's the flow I'm considering...
When an UPDATE page is loaded, I build an array like...
$fields = array("table.field1" => value, "table.field2" => value,
"table.field3" => value)
I then plan to save this array to a SESSION variable. Then, when the
form is posted I save the new form contents to another SESSION variable.
Then I compare the two arrays and save the names of the fields changed
to an array saved in a third SESSION variable. Finally, when I build the
email, I can parse the changed fields array to inform the person who
must approve the changes.
First, does anyone have a suggestion of a better way to do this?
cron job a script for the emails... just in case you have some fool(s)
trying to make 100's of updates per minute.
store the potential changes to an "UPDATE" table or something similar.
admin can then commit the change by updating these proposed changes or
just dump them from the table.
[EDIT] I see that you're doing this below. Nice.
--
How long do you expect people to take to approve the changes? What
happens if they don't approve them? What if they are on holiday? What if
someone changes the data, then someone else makes another change, then
the person who approves them approves the first change?
Your problem, not mine. ;) Seriously those are good questions, but I'm
not going to make policy decisions for you / your company. Your
question about transactions is interesting though... do you mean you
have multiple users that can change the same information?
I would recommend storing the change information in a db.
Say you have a table t_personal_info
Id
firstName
surName
Telephonenumber
dateUpdated
You can then have another table
t_personal_info_pending
With an additional field changeid (to handle multiple changes to the
same record)
With the same fields. When someone approves a change, update
t_personal_info with the change and delete the record from
t_personal_info_pending
Second, I can't seem to save an array to a SESSION variable. I build the
array in a local variable and then set the SESSION variable equal to it.
When I recall the SESSION varialbe, it's contents is "Array". Then, when
I print_r() the SESSION variable, I still get "Array" as the contents.
What's up?
I doubt that references are the issue, but if they are you can do this:
$_SESSION['local'] = &$local;
Are you possibly emptying out the $local array some place? Or are you
emptying out the $_SESSION anywhere? Heck, are you even sure that
you're using the same session from request to request? Or perhaps the
process you use to build the $local and / or $_SESSION['local'] is
flawed and not really building anything.
Thanx in advance for any help.
