I'd say it depends on the size of your project and on any plans to reuse
the code. Classes are better suited for building libraries of code you
use in other projects. And any large project runs into problems with
function names if the programmer doesn't use a rigorous naming system
(like "function package_subpackage_functionname() { ... }") and if such
names are used one could just as good use classes.

Technical difference: Functions are a little bit faster (think of PHP
having to look just one time instead of one time for findeing the class
and one time for finding the method).

Depending on PHP version: PHP4 has an affinity to using functions
because the classes are not as mature and full-featured as in PHP5.
So: with PHP4, you actively have to choose using classes;
with PHP5, you want to use classes.

'method' would be more 'correct'. and I don't agree that it is considered
a function as you are not directly calling the constructor (if it even
exists), but rather instantiating an instance of a class.

but that is all rather purist, and not really in the spirit of php.
regardless you cant write ... :-)

class Test {}
$x = new (Test);

although you can do the following (for the benefit of the OP):

class Test {}
$a = "b"; $b = "Test"; $c = "a";
$d = ( ${${$c}} ); /* (the brackets are optional) */
$x = new $d; /* or: $x = $d(); */
$y = new ${("b")}; /* or: $y = new ${("b")}(); */
$z = new ${${$c}}; /* or: $z = new ${${$c}}(); */
${""} = new Test;
var_dump($x, $y, $z, ${""});

Consistency shares a house with Standards, and you know what
they say about Stan ;-)

Hola lista:
Resulta que estoy tratando de crear un RSS 2.0 para mi web y estoy medio que parado por ciertas y determinadas cosillas. La primera es que las noticias las introduzco en la BDatos usando un editor WYSIWYG (TinyMCE Editor) y entonces en los campos TEXT de la tabla me sale contenido HTML. Por ejemplo si alineo el contenido del TEXTAREA a la derecha me introduce esto en la Bdatos:
================================================
<div align="right">CONTENIDO</div>
================================================
Entonces a la hora de mostrar el fichero XML generado me da problemas porque en el área de la descripción me sale todo ese código HTML. Miren el código para hacer el RSS:
================================================
$contar_noticias = $db->Execute("SELECT COUNT(IDN) AS cantidad FROM noticia");
$rscantidad = $contar_noticias->fetchRow();

    # RSS File
    $res = "";
    $res.= "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
    $res.= "<rss version=\"2.0\">\n";
    $res.= "\t<channel>\n";
    $res.= "\t\t<title><![CDATA[RSS Portal de los Joven Club de Computación y Electrónica de Granma]]></title>\n";
    $res.= "\t\t<description><![CDATA[RSS Portal de los Joven Club de Computación y Electrónica de Granma]]></description>\n";
    $res.= "\t\t<language>es-es</language>\n";
    $res.= "\t\t<generator>RSS Portal JClub Granma</generator>\n";
    if ($rscantidad[0] > 0) {
        $fecha_noticias= $db->SQLDate('d M Y - h:i:s A', 'FechaN');
        $noticia = $db->Execute("SELECT IDN, IDC, $fecha_noticias, TituloN, DescN, AutorN FROM noticia WHERE (NACtiva<>0) ORDER BY FechaN DESC");
        while ($rs=$noticia->fetchRow()) {
            $res.="\t\t<item>\n";
            $res.="\t\t\t<title><![CDATA[" . stripslashes($rs['TituloN']) . "]]></title>\n";
            // $res.="\t\t\t<description><![CDATA[" . stripslashes($rs['DescN']) . "]]></description>\n";
            $res.="\t\t\t<pubDate>" . stripslashes($fecha_noticias) . "</pubDate>\n";
            $res.="\t\t\t<link>" . $PageAdress . "&IDC=" . $rs['IDC'] . "&IDN=" . $rs['IDN'] . "</link>\n";
            $res.="\t\t\t<author>" . stripslashes($rs["AutorN"]) . "</author>\n";
            $res.="\t\t</item>\n";
        }
    }
    $res.= "\t</channel>\n";
    $res.= "</rss>\n";
    $actual =date("Ymd");
    $handler=fopen("../noticias-" . $actual . ".xml", 'w+');
    if (!fputs($handler, $res)) {
        $tpl->assign("msg","No se pudo crear el RSS");
    } else {
        $tpl->assign("msg","El fichero RSS ha sido creado satisfactoriamente");
    }
    fclose($handler);
    $file = "noticias-" . $actual . ".xml";
    $tpl->assign('file', $file);
================================================

Luego el otro problema y un poco OFF TOPIC es que no se como decirle a un arhivo XML que use un fichero XSL para poder mostrar el fichero XML con estilo.

Salu2 y gracias de antemano

When you use the browser to access using the news: protocol you are
actually invoking NNTP functions. That's whats the IMAP functions you
are using are also doing. So that is the proper way. I imagine if you
search for NNTP and PHP you will find some third party classes and
code that might help out too...

Hi, I have enough experience working with PHP on Windows XP over IIS, but
now I need to work on Windows Server 2003, algo with IIS.
I installed PHP (With the installer that I downloaded from www.php.net) but
it doesn't work. When I try to see a PHP page I receive the following
message:

"The server can not found"

What can I do?

Ahead of time, thank you very much.

actually the underlying 'OS' does support something I think they call
hard links - but you need a 3rd extension to use it (free download somewhere,
gives you an extra item in context menu) ... behold the power of the dark side. :-)

Without looking up this specific error code thoroughly through Google or
elsewhere, I would have to ask you to submit the code excerpt that
generates this error. If it is a permission error it could be because
you are trying to listen to a system reserved port in the 0-1024 range,
or it could be that the URL that you are trying to open is actually
invalid. For instance, if trying to connect to http:// you could have
forgotten a slash, or used backslashes, or any other common mistake.
Please submit more information the next time, and use Google, it
actually finds information for you. :)

Torgny

Tried Google and the guy who created the snippet they had no helpful

It would be nice to have a php function valid_email or something but
until then i suppose we just make do with what is available, for what I
need I use the following:-

eregi("^[a-z0-9]+([_\\.-][a-z0-9]+)*"
.""."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a-z]{2,}"."$",$email)

Ive never had problems with it but have up to now no need for
multilanguage validation.

What is wrong with that validation anyway?

hi..

before i reinvent the wheel...

i'm looking for some code that i can modify to use as a job posting
app...i've been looking over google/freshmeat/sourceforge/hotscripts/etc..

my basic needs:
-allow user to enter job function, for a number of fields
-allow user to maintain/update/delete/enable to jobs
-allow admin to enable/disable users
-allow user to login/register
-allow company user to create jobs
-allow regular user to submit resume for a job

if anybody knows of job posting/resume code, great! if you alos know of a
different app that i could look at, and possibly rewrite/reengineer to get
what i need, i'll take that as well..

this is for testing, more than anything...

thanks

I've written a script to munge and import 108,000+ records.

To avoid spiking the server, I'm sleep()ing 1 second for each record.

So it takes 30+ hours to run, so what?

This data changes "daily" but not really much more often than that,
mostly.

Anyway, it seems to be using an awful lot of RAM for what it's doing.

Like, 80 Meg or so.

php.ini memory_limit is set to 100M by my ISP. I can use my own
php.ini and change that, if needed.

Most of the fields are short, and the longest is maybe a varchar(255)
and there are only ~15 fields.

There's only a couple $query strings in each iteration, a couple MySQL
result handles, and 2 copies (raw and munged) of each field's data.

That don't sound like 80 Meg worth of data to this naive user.

I got worried about the RAM, so stopped the process and added some RAM
usage calls, started it over, and am logging the RAM usage at each
record.

I've written a "pretty" PNG graph and I'd like some experts to look at
the graph, look at the code, and then tell me.

1. Do I have a memory leak that is gonna kill me and I have to fix it?

2. Is PHP's garbage-collection so non-aggressive that this is just
"normal"?

3. Is there some kind of 80/20 or 90/10 "rule" in the guts of PHP
garbage-collection, so that reducing my memory_limit would just "fix"
this?

4. Can you spot any obvious/easy ways to alter the source to reduce
memory usage without micro-managing or adding needless complications
nor, perhaps most important, adding too much time onto the 30-hour
process.

Below is a link to the graph, some commentary, and there's a link to
the PHP source code at the bottom-right of the web page.

Hope all this isn't too presumptious...

TIA!

Because of the way it spikes and maintains, I'm guess that this is normal behavior, but we'll see what the real experts have to say.

In theory, if you allow a process 100MB of memory and it thinks it might need some stuff again later, it's likely to cache for faster reuse of that data later.

But putting all that aside, because I really have no idea, only hunches, I'm wondering if you might want to rethink how you're doing this in general.

Does it make a difference if instead of one record at a time, you pull 10, 20, 100... might speed up your process a little and if it doesn't use any more memory, then why not?

Another thought.. can you use database replication here? So instead of dumping all the records and processing and inserting the ones that are new, you'd only be acting on what's changed since the last backup. With real replication, you can do this realtime (or at least semi-realtime), but you could simulate replication in your PHP script as well.

The idea is to see what INSERT, UPDATE, DELETE and ALTER (maybe some other) commands are run on SourceDB and perform the same actions on DestinationDB. This can be done by either recording the actions for "playback" on the DestDB later or by performing the same actions on the DestDB at the same time as the SourceDB effectively mirroring the databases.

I'm not sure what 'data munging' is going on or if this is the right solution for you, but it might be worth checking into.

Here's the manual page for MySQL's replication:
http://dev.mysql.com/doc/refman/5.0/en/replication.html

But if you get the theory, you could easily keep a list of the INSERT/DELETE/UPDATE/etc that your scripts do on SourceDB and either do the same thing on DestDB right then, or "play it back" later like during nightly maintenance.

Good luck Richard!
