I'm hopeful this is a solved problem, and I'm just not searching for the
right thing yet.
I'd like a way to send a 'notify' to php processes that want it, without
the use of a moderator or helper process. One way I tried is to use
Daniel Rozsnyo multicast patch and have each php process join a
multicast group and wait. Interestingly, this works when invoked on the
CLI, but not from a browser. Daniel suspects there may be some
interference from apache.
The basic problem is sort of akin to a chat program. Multiple clients
join and sit waiting for new messages. Using ajax, I open an http
connection to a php script on the server, which then waits for a certain
amount of time for a message. If none arrives, I respond as such and a
new connection is created. Otherwise, I send the message back to the
client. I need some way to notify the waiting processes that there's a
new message so they can spring into action.
Thanks!
Marty

Not realy right, because the Music-Industry try to enforce a
International Law which they permit to contact directly the
ISP's for informations about customers...
So, this law can be misused in any case...
And as I have already sayed, if they get ONE time infos about
me, I am tracable worldwide with my Laptop which let me run

Google and privacy violations.

This is not right... Once they HAVE infos about your ISP, you are
tracable and Google hast the posibilities and resources to do it.

Not realy, since IF YOU are collecting data of customers/visiort you are
responsable for this stuff and for ANY misuse you can be sued.

Yes but by "European Law" you have to destruct the data after 3 month.
Otherwise your customers must aggree with you, e.g. signing a form on
your website.

Ehm? I can anylyze logs and more by cookies... Google is settings
cookies in mass which then can be used by Google to identify the user.

I was talking about your urchinTracker() which out of your control.
Google is advertising this service to INOCENT Website-Owner which then
put it into there webpages and then Google give you some infos about
your visitors back and you are happy...
But you do not know, WHAT Google does with the other infos collected...
You are helping Google to violate privacy.

urchinTracker() does much more....

You clearly think you're right, which is your right, but I'm not
sensing any openness to alternative points of view so this will be my
last comment on this pointless conversation. It's just not fun anymore.

"try". Yup, that's right *you* said try. They need a court order to
get that information (which is what I said) and they always will. If
they can show that they have reasonable cause to believe someone has
broken the law then a court order will be forthcoming. I don't have a
problem with that, and if you have nothing to hide neither should you.
[IMHO]
So, this law can be misused in any case...
And as I have already sayed, if they get ONE time infos about
me, I am tracable worldwide with my Laptop which let me run
into heavy trouble.
I can't really reach any conclusion from that statement other than
that you're breaking the law. You might want to stop doing that - you
might be able to relax.
Again, if you want to block it I have no problem with that. I think
you're overly cautious but it's entirely your choice.
There are since years threads in many Forums arround the world
about
Google and privacy violations.
Don't really see the relevance of that comment and my comment. Are you
actually reading what I'm typing? Block it if you want, I don't give a
rats behind, but (yes, back to the actual point I originally made)
don't block half of it and then complain that it's causing errors.
Google Analytics (which is where the Urchin code comes from) does
gather a tiny bit more information than normal server logs but none
of
it is personally identifiable or in any way a security risk. But just
This is not right... Once they HAVE infos about your ISP, you
are
tracable and Google hast the posibilities and resources to do it.
You are *anonymously* traceable. They still need a court order to
connect that information to you personally, and they don't hand those
out without just cause. Again, I suggest you stop breaking the law so
you can relax a bit.
Then don't use sites that use it from those countries. Or, better
yet,
turn your computer off and go play outside.
Really don't know where you're getting that from, but if it's even
remotely true nobody would be using Google Analytics. I'm betting
you're confusing Analytics with something else Google do, but for the
life of me I can't think what.
Sorry but it was already in the Press that the NSA is using Google
and
they have confimed it officialy!!!
Reference please? *How* are they using it? Are they using it like any
other individual or organisation would use it, or do they have an
illegal arrangement with Google to get access to personal information?
Just looking for more than your word, that's all.
Ooh, give 'em a peanut. I live and work in the UK and every site I
work on that uses Google Analytics has nothing specific about Google
Analytics in the privacy policy. They all talk about use of cookies,
IP addresses and server logs and I've never had any complaints.
Because most users care about there priacy?
I assume you mean "most users don't care". If people cared about their
privacy they'd do everything with cash which they'd stash under their
mattress, wouldn't use loyalty cards and certainly wouldn't go near
the Internet. Total privacy is overrated and extremely inconvenient.
I'd end with "get over it" but I just don't see it happening so let's
go with "live with it".

Hi all.
I'm currently working on a project that's in its beta stage. Due to
time restraints, we were unable to build in transactions from the
beginning. Well, we're getting to the point where we can now put in
transactions. Basically, I'm curious to find out your opinion on the
best way to accomplish this.
Currently, my thoughts for doing this are:
<?php
function someFunctionThatNeedsTransactions ()
{
$this->db->begin(); // Start transaction
$this->db->query("SELECT..."); // Run my queries here
$this->db->query("UPDATE...");
// Do some PHP logic here
$this->db->query("SELECT..."); // Run more queries
$this->db->query("INSERT...");
$this->db->commit(); // Commit transaction
}
?>
If there was a failure in one of the queries, that would be caught in
the database class ('db' instance) and <?php $this->rollback(); ?>
would be called. Note that all the tables are InnoDB and the above
code/functionality works.
Ideally, I would have liked to use stored procedures, but that
decision was not mine. So are there any complications I'm potentially
missing? Any other thoughts on the direction to go at this point?
Thanks in advance,
~Philip
PS... No, I didn't have too much coffee this morning, Robin. ;)

I'd get your db class to handle nested transactions, so if you had
something like this:
$db->begin();
....
someFunctionThatNeedsTransactions();
...
.. oops, need to rollback.
$db->rollback();
the bits between "someFunction" and the "rollback" will be committed (by
the function) and can't be rolled back.
See http://dev.mysql.com/doc/refman/5.0/en/savepoints.html
The situation might not come up but it can't hurt to have it already
built in "just in case".

HI5.COM, Enter hotmail address and password can get your contact list, who
can tell me how to ?
that skill is SDK ? API ? or Script ?
i know fsockopen can make it, but it like hacker, not propriety...
if Window Live Contacts API, this need end-user agree, but HI5.COM not like
it, no need agree, or HI5.COM really using hacker skill ?
who can give me idea ? i want make that like HI5, detail and sample please
Thank You Very Much !!

I have a form statement with: <form name=memjoin"

when I click the submit button, the web address appears in the firefox
address box, but no page appears on the screen. and when I try to view the
page source code from the firefox "view" drop-down menu there is no source
code. the page is in the correct directory and I can open the source in IE

message. I'm at a lost as to what might be the matter. does anyone have an
approach to solving this problem or know what the cause might be?

Check the php.ini on the server that hosts caamesuem.org (is it your
server?) and see if display_errors is enabled. You generally shouldn't
enable this on a production server,
but it could be very helpful right now. If it's disabled, it might be
suppressing a helpful error message. Remember to restart your web
server if you change the php.ini.

Carlton Whitehead

i added __set() to my original class, now i can do cool stuff, like this:
$a = ArrayClass::simpleFactory(getArray())->{'a'} = 5;
which allows retrieval of the array, and modification (or access) to a given
member, in a single statement.
<?php
class ArrayClass {
private $theArray = array();
private function __construct($theArray) {
$this->theArray = $theArray;
}
public static function simpleFactory($theArray) {
return new self($theArray);
}
public function __get($member) {
if(array_key_exists($this->theArray, $member)) {
return $this->theArray[$member];
}
return null;
}
public function __set($member, $value) {
$this->theArray[$member] = $value;
}
}
function getArray() {
return array(
'a' => 1,
'b' => 2
);
}
$a = ArrayClass::simpleFactory(getArray())->{'a'} = 5;
var_dump($a);
?>
maybe boring to some (or many :D) but as the first time around, i just
thought it was cool and id share.
