Richard, this is what the docs are talking about:
list($a,$b,$c,$d) = array('a','b','c','d');
echo $a,$b,$c,$d;
vs.
list($a,$b,$c,$d) = array('a'=>'a','b'=>'b','c'=>'c','d'=>'d');
echo $a,$b,$c,$d;
In your case you are calling each() which itself returns a numerically
indexed array.

Ok, that was not the really right answer ;) Of course it does work.
You can even do stuff on that element, if you use the variable, resp.
reference ($oMyElement) for doing this.
What doesn't work (and I referred to that) is getting this object
back from the DomDocument, so for example:
$oDom->documentElement will give you the DomElement back and not your
new MyElement.
Hope it's a little bit clearer now

At the same time, for the real include_path includes, make sure that most of your includes hit the first include path. If PHP has to scan multiple dirs on every include it will be slower than it needs to be.

[PHP] Extending Element class in a dom tree?
The DOM implementation i PHP5 allows classes to be extended. Extending
the Document class is no problem, but how can I extend the Element class
and use it in a DOM tree?
DOMDocument::createElement returns a DOMElement object which you cannot
extend.
Could this be a solution?
class MyElement extends DomElement {
function __construct($a_stTagName) {
//has to be called!
parent::__construct($a_stTagName);
}
function myFunction() {
// do something
}
}
$oDom = new DomDocument();
$oMyElement = new MyElement('mytag');
$oMyElement = $oDom->importNode($oMyElement, true);
$oMyElement = $oDom->appendChild($oMyElement);

Yes, I completely agree that business logic should be separated from
presentation logic. Only problem I have is that from there people go on to
conclude that html does not need to be sseparated from presentation logic.
As far as I see It is a very good idea to keep all 3 of them separated.
Bussines logic from presentation logic by proper organization and code
design in php, and presentation logic from html by template engine.

What usually is the problem is that template systems define its own
programming language, with constrructs for loops, if's and whole other bunch
of stuff to model dynamic behavior. And I agree with you that this makes
diffrence between using such template system, and just php as template
system much, much smaller.
Where I do not agree, is that "fat template" syndrom is common to all
template engines, and that it is inveitable. For instance my TemplateTamer,
is now almost 5 years old, and it never had any sign of becomming
programming language in it self, and it never will. It has a markup language
of only 6 idioms:
{VARIABLE}
{#TRANSLATE}
and there is no single sign of presentation logic inside html template, no
ifs, no loops, no calls to the methods or functions, nada. All presentation
logic is written in php, and in nicely separated logic.php file.

Re: [PHP] Regular expressions problem

Depends on what regexp function you use, what exactly you want to match,
and whether or not you want to know, after you match, any of the
segments. Rasmus has given you one possible pattern that works with the
ereg functions. If you wanted to use a preg function and wanted to match
3 digits, a space, two m', one or more spaces, and 3 digits, you would
use:
preg_match('/^\d{3} mm\s+\d{3}$/', $string);
But, what it all comes down to is: you need to determine what PATTERN
you need to be able to match. Once you know that, you can write the
regexp.

Re: [PHP] How to know if php CAN write files on server and WHERE it can?
Thanks Richard for your answer Il giorno 29/apr/05, alle 10:07 PM, Richard Lynch ha scritto: If you're just going to delete the files after your script is done, why copy them somewhere else at all? Your best bet is to try and use the /tmp dir, or, more properly, what PHP thinks is a "good" place for tmp files. I developed an application that uploads files on the server calling a php page, using post just as a form would be. to avoid the max_file_size and max_post_size problems, the application splits large files on smasller chunks, and calls repeatedly the php sending one file chunk at a time, every time waiting for a response from the php page and then reposting to it subsequent chunk of data. So the php script is called more times, one for every chunk, and at the last call It's up to the php script to re-construct the entire file when all the uploads are finished, and then copy it on a known location using ftp. That's why I would like to move every temp file on another directory, since I'm not assured that php temp files will keep existing during all the upload process transactions ( or worst, could be php engine itself deleting them immediatly when php script execution ends? ) Hope was clear what I'm attempting to do... regards, Giulio For that matter, using http://php.net/tmpfile may take care of all your worries on this one.

Re: [PHP] sessions problems
Hi,
When someone hit the logout page say "logout.php".
You can write the code in that page itself to update
the record. Since the username of that particular user
is stored as a session as long as the user closes the
browser window.
So in the logout page you can add like this.
session_start();
include("connect.php");
$uname=$_SESSION['username'];
$sql = mysql_query("UPDATE users SET online='0'
WHERE username='$uname'");
//alternatively u can also delete that particular user
from the database instead of updating the online
status to '0'.
I hope this might help you.
