Shouldn't that be:

$rdfpicdata = rdfpic2html( $rdfpicdata );

Since you haven't defined rdfpic2html as receiving its argument by
reference...

Looks a bit odd to me :) But could be because you're using outdated
semantics. It should be sufficient to do the following:

<?php

session_name( 'CCLTrolley' );
session_start();

//
// Initialize the trolley.
//
if( !isset( $_SESSION['TrolleyContents'] ) )
{
$_SESSION['TrolleyContents'] = '';
}

//
// Add new entry.
//
if( isset( $_POST['AddToTrolley'] ) )
{
    if( $_SESSION['TrolleyContents'] ) == '' )
    {
        $_SESSION['TrolleyContents'] = $_POST['AddToTrolley'];
    }
    else
    {
        $_SESSION['TrolleyContents'] .= ','.$_POST['AddToTrolley'];
    }
}

echo $_SESSION['TrolleyContents'];

phpinfo();

Is there a reason you're using a comma delimited string? I would
recommend using an array instead:

<?php

session_name( 'CCLTrolley' );
session_start();

//
// Initialize the trolley.
//
if( !isset( $_SESSION['TrolleyContents'] ) )
{
$_SESSION['TrolleyContents'] = array();
}

//
// Add new entry.
//
if( isset( $_POST['AddToTrolley'] ) )
{
$_SESSION['TrolleyContents'][$_POST['AddToTrolley']] =
$_POST['AddToTrolley']
}

echo implode( ',', $_SESSION['TrolleyContents'] );

phpinfo();

Cheers,
Rob.

Why is it outdated semantics?

P.S. do folks prefer I reply on top or on bottom?

Might i refer you to:

http://ca.php.net/manual/en/language.variables.predefined.php
http://ca.php.net/manual/en/function.session-register.php

$HTTP_POST_VARS has been considered deprecated for some time now.
session_register() is considered clumsy and dangerous since it is only
works with register_globals enabled which is itself considered poor
coding style in this enlightened era of PHP.

I believe he was referring to your use of $HTTP_POST_VARS and
session_register, which have been replaced by $_POST and $_SESSION,
respectively. The manual will have more details.

Well, I can't speak for everyone else, but personally, bottom, as long
as you trim your posts :)

Some people don't care, but those that do care have loud voices and
would prefer you bottom post since they haven't yet been upgraded to
random access reading and are still hooked up to a tape drive :B

So use
$_POST["AddToTrolley"]
instead of
$HTTP_POST_VARS["AddToTrolley"]?

And $_SESSION instead of session_register and always access your session
vars through $_SESSION.

I've never been very good getting my head around arrays.
Then how do I check to know if $mydata->RNum is in
$_SESSION['TrolleyContents'] ?
Thanks for your patience.

Should be. The docs state that the $_XXX series of vars were introduced
in PHP 4.1.0.

If you go with an array system might I suggest the following change to
what I wrote:

<?php

session_name( 'CCLTrolley' );
session_start();

//
// Initialize the trolley.
//
if( !isset( $_SESSION['TrolleyContents'] ) )
{
$_SESSION['TrolleyContents'] = array();
}

//
// Add new entry.
//
if( isset( $_POST['AddToTrolley'] ) )
{
    if( isset( $_SESSION['TrolleyContents'][$_POST['AddToTrolley']] ) )
    {
        $_SESSION['TrolleyContents'][$_POST['AddToTrolley']] += 1;
    }
    else
    {
        $_SESSION['TrolleyContents'][$_POST['AddToTrolley']] = 1;
    }
}

echo implode( ',', array_keys( $_SESSION['TrolleyContents'] ) );

phpinfo();

To check if something is in the trolley:

<?php
if( isset( $_SESSION['TrolleyContents'][$myData->RNum] ) )
{
echo 'Yaaaaaaaaaaaaaaaaay!';
}
?>

To decrement the quantity of an item in the trolley:

<?php
if( isset( $_SESSION['TrolleyContents'][$myData->RNum] ) )
{
    $_SESSION['TrolleyContents'][$myData->RNum] -= 1;
    if( $_SESSION['TrolleyContents'][$myData->RNum] <= 0 )
    {
        unset( $_SESSION['TrolleyContents'][$myData->RNum] );
    }
}
?>

I'll leave it as an exercise for you to add or delete X quantity.

hello again
I have been battling this mysterious char thats showing up in the buffer
when i first log onto my chat, or else try to add new things to the logon
function, I am getting the code not to "fall through" to the next prompt
however, using $varname = socket_recv($sock, $read, 1024, 0)
this won't put anything but a number in that variable, say for example the
passwd was 'test'(just for the sake of testing for now), the password
would end up being not test, but maybe the number 5 I'm assuming its
returning the number of digits but this is totally not what I expected,
and the manual for socket_recv is um, well for a lack of better wording,
its not there on the website anymore, all except the format of it, no
descriptions or anything, should i be using something else instead of
socket_recv()?

attached mail follows:

Of course you are right. I was fooled by this page:

http://www.wiki.cc/php/RecursiveIterator

<?php
class RecursiveArrayIterator extends ArrayIterator implements
RecursiveIteratorIterator
{
     function hasChildren()
     {
         return is_array($this->current());
     }

     function getChildren()
     {
         return new RecursiveArrayIterator($this->current());
     }

?>

Hi all,

I wrote a php script which is running very long queries (hours) on a
database.
I seem to have a problem to run the code when there are single queries
which take long times (like 5 hours for an update query), from the log
of the database I received the following code:

2005-09-30 17:12:13 IDT postgres : LOG: 00000: duration: 18730038.678
ms statement: UPDATE product_temp SET nleft=(SELECT
2005-09-30 17:12:13 IDT postgres : LOCATION: exec_simple_query,
postgres.c:1035
2005-09-30 17:12:13 IDT postgres : LOG: 08006: could not send data to
client: Broken pipe
2005-09-30 17:12:13 IDT postgres : LOCATION: internal_flush, pqcomm.c:1050
2005-09-30 17:12:13 IDT postgres : LOG: 08P01: unexpected EOF on client
connection
2005-09-30 17:12:13 IDT postgres : LOCATION: SocketBackend, postgres.c:287
2005-09-30 17:12:13 IDT postgres : LOG: 00000: disconnection: session
time: 6:04:58.52
2005-09-30 17:12:13 IDT postgres : LOCATION: log_disconnections,
postgres.c:3403

Now after the 5 hours update it need to echo into a log file a line
which say that it ended this command (just for me to know the times), my
assumption is that PHP read the code into memory at start and opened the
connection to the file, after a time which he waited to any given "life
sign" he gave up and closed the connection to the file, and when the
code came back to the file it encountered no connection to the file
(broken pipe).

Am I correct at my assumption? if so how can I set the PHP to wait how
much I tell him?

Ofcourse if im wrong I would like to know the reason also :)

Thanks in advance,

It is a really serious problem, PHP 5 have so much good things specially in
terms of XML that I just want to use them in my programmes but whenever I
decide to do programming in PHP 5, I stuck on the choice of a good server.
Most of the Hosting service providers are still providing hosting in PHP 4.
I think PHP is going through a very tough phase. It has got the
capabilities but we can not use them, thats why we can SAY that PHP is good
programming language But we can not PROVE that in practically.
Well the original posting was about hosting service provider, somewhere I
read about HOSTWAY. they are in PHP 5 hosting.

Dear experts,

something must be terribliy wrong with either php5<->com or our
configuration/code.

We used to control MS-Index-Server via php4 without any problems:
----------------------------------------------------
$q = new com ("ixsso.Query");
$util = new com ("ixsso.util");
$q->query = $QueryText . ' AND #filename "(*"';
$q->SortBy = "rank[d]";
$q->catalog = "docs";
$q->Columns = "filename, Path, size, characterization, rank";
$q->MaxRecords = 300;
$util->AddScopeToQuery ($q, "/", "deep");
$q->LocaleID = $util->ISOToLocaleID("EN-US");

$rs = $q->CreateRecordSet("nonsequential");

// Loop over result
while (!$rs->EOF)
{
........

$rowcount++;
$rs->MoveNext();
}
----------------------------------------------------

Since we migrated to php5 we changed the iterator to run with FOREACH which
causes a fatal error:

foreach($rs as $ResultCounter)
{
...

}
--> Fatal error: Uncaught exception 'Exception' with message 'Object of type
variant did not create an Iterator'
in..
Same thing happens with:
foreach($rs as $ResultCounter => $row)
{
...
}
--> Fatal error: Uncaught exception 'Exception' with message 'Object of type
variant did not create an Iterator'
in..

Also, we tried to use the com-exception try..catch which didn't work either.

What's wrong here???

Environment :
win XP/2003, Apache 2.0.53, php 5.0.5

I'm thankful for any hint!
Marc
