Yes, there are a bunch of arrays in the program.
This is on a DSL line... ?? Would the asynco thing be likely, or
possibly even standard, with DSL?
Did you come up with a workaround?

I had same problem and it involved an array. In my case there was a typo,
and the array I was trying to do something with didn't even exist, but it
was hard to find because instead of dying with an error it would just sort
of sit there, not outputting anything further, until I clicked stop in the
browser.
Can't remember more details.
Haven't had problem since, we upgrade with releases.

I wrote a very compact stand-alone XML interpreter
for the Amazon.com XML webservices interface:
http://www.chipdir.nl/amazon/
The part that interprets the XML code is
only about 30 lines long. Please consider
that I can't guarantee that it's useable
as a general XML-interpreter, because it
was written with the quite neat Amazon
code in mind.
The code may also not be useable for big
source files. Furthermore the code reads
the XML code in such a way that the resulting
array stays as shallow as possible. To this
end certain information is not stored in the
array, and therefore it's not possible
to regenerate the XML code from the array
again.
I have also been busy expanding the script
code into a similar HTML interpreter (which
is much harder of course) but that means
that I don't have a very clear picture in
my head about what the quality of the XML
interpreter currently is. I think I have
found some serious improvements while
working on the HTML version.
One of the problems I encountered whilst trying
to keep the resulting tree shallow was, that
when you interpret something like:
<a>
<a>_data_
<b>_data_
<c>_data_
(I'm leaving out the end-tags.)
You can't put the a,b,c in an associative array,
with a,b,c as index, because every index should
be unique and the sequence might as well be:
<a>
<a>_data_
<b>_data_
<b>...
<c>
This means that you have to put the elements in
an enumerated array.
But in the case of say:
<author>
<name> _data_
<street> _data_
<city> _data_
One really would prefer to put them in an associative
array.
Of course one could check first if all the fields
are unique and decide then, but this might lead
to the fact that XML code like:
<authors>
<author>_data_
<author>_data_
<authors>
<author>_data_
leads to arrays of different depth.
I haven't checked yet if interpreting the DTD
could help to resolve this issue.
Greetings,
Jaap

I generally keep it like this, so that the first user is logged out.
This way the user is alerted that someone has "hijacked" their account
and they can act upon it.
If you do it another way so that the first person remains logged on and
the second user is denied access, you'll just need some extra flags in
the database. Set a "logged_on" column when the user logs on and if
another user tries to use the same name and the "logged_on" column is
set, deny them. The issue you'll run into with this though, is how do
you know someone is logged off? Sure, some people may use the log off
button, but others will not. So you have to come up with a "timeout"
script. What if I accidentally close my browser and come back to log in?
The system will not let me because I'm still "logged_in" until X minutes
pass. Also with this method, you need to keep track of these attempted
log ins and somehow alert the first user.
Hope that helps.

good question i'm checking this out atm :|

hmmm,
for me these few line are working well, user cannot login before
max-idletime is reached.... (i check the list every time an action is taken
on the board, if no user is online, i cant login forever and have to connect
as another user first ;)
thats all, you could check idletime for all users at the login window and
log them out if reached - before logging in ....

And you call that a viable solution? That's ridiculous.

ok here is the latest sql query
SELECT username FROM users WHERE (logged_in=0 OR (NOW()-last_login) > 300
AND username='".$this->post['username']."'"
there is the idle time added but what after the idle time they log bak in
and then kiks the first login out ? there must be a better solution ??

ok well i just noticed my sql statement is a bit flakey as its not a true
idle time to get a true idle i'd have to keep a record of the time every
request to the pages when logged in, this is checking when they lasted
logged in so the user may still be logged in 300 seconds later , this isnt
really idle especially when the users will be fulltext searching a table of
100K + records :|, any suggestions ?

Is it possible to reference two instances of an object at once with a
single variable name while retaining the ability to reference the
objects seperately?
I am using the PEAR Template IT package and need to generate two similar
but different results at the same time. I am doing this with two
instances of the IT class ($tpl1 and $tpl2).
I have some code like this:
$tpl1->setVariable("var1","This");
$tpl2->setVariable("var1","This");
$tpl1->setVariable("var2","That");
$tpl2->setVariable("var2","That");
$tpl1->setVariable("var3","Something");
$tpl2->setVariable("var3","SomethingElse");
I would like for this to be:
$tpl3->setVariable("var1","This");
$tpl3->setVariable("var2","That");
$tpl1->setVariable("var3","Something");
$tpl2->setVariable("var3","SomethingElse");
Where $tpl3 is a reference to both $tpl1 and $tpl2.
Is this possible at all? It seems to make for very clean code for me,
but I can't think of how it could be possible.
Thanks in advance.

No chance. Well, you could hack it with some really fancy object
overloading, but in general, no, you cannot have a single reference that
references two distinct objects. References work the other way around.
Given a single distinct object, you can create multiple equivalent
references to it.

Not using references.
I once built a small class that handles such stuff. Basically it's a
container for object references that are attached to it, and it will
execute any method to all objects simultaneously. Code plus testbed is
attached below.
The base implementation of CTeeObject checks if that all attached objects
are of the same class of the first attached object, or at least derived
from it. This is how I needed it but it's not mandatory, as the call agent
method or CTeeObject checks each attached object if the method exists. Upon
attaching objects, CTeeObject calls its check_object() method if the object
is ok to attach - you may override this method in a derived class to
perform less or additional checks.
For example you could provide a specialized CTeeObject-derived class that
doesn't use the generic call agent (for performance reasons) but calls
object methods directly (which would be quite feasible in your case). Use
the overridable check_object() to check if the object to attach has a
supported class.
<?php
class CTeeObject {
var $arObj;
var $class;
function CTeeObject() {
// we do nothing in the constructor class
// use the attach() method
$this->arObj = array();
}
function attach(&$hObj) {
// if this is the first object, simply accept it.
// for all successive objects make sure they have
// the same class (or at least derived from).
if (!count($this->arObj)) {
if (is_object($hObj)) {
$this->arObj[] =& $hObj;
$this->class = get_class($hObj);
}
}
else {
if (!$this->check_object($hObj))
return false;
$this->arObj[] =& $hObj;
}
return true;
}
// override this method in your derived class
// for additional class checks
function check_object(&$hObj)
{
return is_a($hObj, $this->class);
}
// generic call agent
function call_method($method)
{
// accessing unlisted arguments will trigger a notice/warning
// this is unavoidable here so modify error reporting
$erep = error_reporting(E_ERROR);
// build a list of arguments to pass
$arglist = array();
for ($i = 1; $i < func_num_args(); ++$i)
$arglist[] = func_get_arg($i);
// build the method call
$cmd = null;
for ($i = 0; $i < count($arglist); ++$i)
$cmd .= ($cmd ? ',' : null) . "\$arglist[$i]";
$cmd = "return \$hObj->$method($cmd);";
// error reporting to standard
// to have it available in the object implementation
error_reporting($erep);
// now walk all attached objects and execute the required
method
// but check if the object is still an object and that the
method exists
$result = array();
for ($i = 0; $i < count($this->arObj); ++$i) {
$hObj =& $this->arObj[$i];
if (is_object($hObj) && method_exists($hObj, $method))
$result[] = eval($cmd);

$result[] = null;

Just noticed a small glitch in the attach() method - check_object will not
be called for the first object. Use this attach() / check_object()
implementation instead. The "var $class" instance variable of CTeeObject
can be omitted.
function attach(&$hObj) {
if (!$this->check_object($hObj))
return false;
$this->arObj[] =& $hObj;
return true;
}
// override this method in your derived class
// for additional class checks
function check_object(&$hObj)
{
// if this is the first object, simply accept it.
// for all successive objects make sure they have
// the same class (or at least derived from).
if (is_object($hObj))
return (!count($this->arObj) || is_a($hObj,
get_class($this->arObj[0])));
return false;
}

If they are coming out of your database, why not get your database to do

Right... I never thought of this.
But can I use this if what I'm trying to get the (price * quantity).

?? Are you reading that chapter at all? Closing the browser has
absolutely nothing to do with aborted connections unless the browser is
closed while data is actually flowing across the wire. You are completely
on the wrong track here. HTTP is a simple stateless protocol. Sessions
can be used to emulate state, but that doesn't mean you suddenly have a
stateful connection-oriented protocol. Between clicks of your browser you
do not have an active connection from the browser to the web server (with
the minor exception of keep-alive connections, but they aren't what you
think anyway, so ignore those). Since you don't have an active
connection, closing your browser could not possible abort a connection.

Hi,
Is there any body who have experience with the flags in mysql_connect() in
php >= 4.3 . Especially the MYSQL_CLIENT_COMPRESS flag.
I dont know if it works or not. I cant make any difference. Should php must
be compiled with a special flag to get work this?
Thanks

Actually, the session ID has to appear in every URL... if you compile PHP
with enable-trans-sid, then PHP takes care of this for you in *most* cases.
As you say above, you need to append them manually to things like header()
redirects.
One way around this would be to write a simple wrapper function which does
this for you automatically:
<?
// UNTESTED
function redirectWithSession($location)
{
$sid = session_id();
$sname = session_name();
header("Location: {$location}?{$sname}={$sid}");
}
?>
Then (after testing the above code thoroughly) you just need to do a batch
search and replace on your whole site source for 'header("Location: ' with
'redirectWithSession(', and everything should be cool.... I think. Please
test all thoroughly :)
Or, just go through your code and patch it up :)

There is no difference in the security risk between URL and cookies, if they
are sent in plain text. SSL is a different story.
You have a choice: make sure your site can be used without cookies (and
deal with the small effort during development), or be prepared to turn away
users.
I know which I picked :)

Maybe it's just that it's late, but can't seem to figure this out. I
want to show a shipping price depending on the amount of purchase. I
thought about using a lot of if() statements, but I know this is not the
best way to go about this.
Can anybody enlighten me on this one and give me a better approach.
Here is an example of my shipping rates:
Less than $20.00 = $7.45
$20.01-$35.00 = $8.45
$35.01- $55.00 = $9.45
$55.01-$80.00 = $10.45
$80.01-$100.00 = $11.45
$100.01-$150.00 = $13.45
$150.01-$200.00 = $15.55
$200.01 or more = $19.45
Thanks.

Better approach in what sense? From a performance perspective you are not
going to beat a specific set of if conditions unless there is an distinct
formula you can apply. I will assume there is no simple mathematical
relationship for your full set of data and what you are really looking for
is a way to just feed the pricing structure into your code by some
mechanism and then have it just work, so your goal is to make it more
maintenable. To that end, you could stick your pricing table into an
array of arrays and simple loop through it. Something like this:
function find_rate($num) {
$rates = array(array('7.45'=>20),
array('8.45'=>35),
array('9.45'=>55),
array('10.45'=>80),
array('11.45'=>100),
array('13.45'=>150),
array('15.55'=>200),
array('19.45'=>999999999));
foreach($rates as $i => $vals) {
if($num > current($vals)) continue;
else { $price = key($vals); break; }
}
return $price;
}
This should return the correct shipping price for whatever you pass into
find_rate().
