I do a lot of research into SEO, and the only evidence I've found that
comes close to this is where a website set up a page containing a
fictional keyword in the URL, then searched for that word a week or two
later.
I don't know how valid the 'SEO friendly URLs' are though. How often
have you searched for the answer to a question online and had the top
few results turn out to be forums with dynamic query-string URLs?!
Thanks,
Ash

I hope here is a proper validation there, 'cause as is, sounds truly dangerous,
since you are not using bindParams or other PDO related techniques to avoid
input problems.
About the rest I kinda agree with the proper model controller, rather than just
a reader.

Subject: [PHP] Insult my code!
Hi there,
I'm in the process of trying to wrap my head around MVC, and as part of
that, I'm attempting to implement a super-tiny MVC framework.
I've created some mockups of how the framework might be used based
around a very simple 'bank', but I'm trying to get some feedback before
I go and implement it, to make sure I'm actually on the right track.
Any thoughts would be much appreciated!

Controller - http://www.pastebin.cz/23597

The linked code was supposed to be more of a mockup than anything, with
the functions a bit of filler to try and show what I'm trying to do.
With regard to the SQL injection, I try not to make the problems with my
code quite so blatant. :-)

Hi Paul,
As I agree some of your thoughts, I want to add my opinion also.
Yes the code should work. That is why we earn Money. If it doesnt work, then we are on
fire. But things like OOP or MVC weren't invented for a better running code. They are
invented so the codes will going to be much more clean, readable, reusable, maintainable.
"Running codes" is not enough.
Eric asked about how his MVC structure looks. And we are trying to help what we know
about MVC. He didn't asked if the code is fine for running. So giving an answer "The
real key is, does it work, and can it be maintained" is not enough and not really
helpful to him on MVC concept. If you need just a running and maintainable project, you
don't need to use MVC (MVC is not all about that). We are not criticizing his code(the
code is really fine(except injection problem :-) ) and very readable)
Eric,
As Martin said, All the business logic should be in Model. Controller should not tell a
model "Save it to this database, select it from this table, use this
db_adapter" etc. A controller is like a maestro of the system. It askes the model to
play piano loud. But it wont say which key of piano, the model should touch.
I suggest you to read this online book about Zend Framework and MVC. Its really
really very helpful to understand the concept. Also example codes are very
clean and good.
http://www.survivethedeepend.com/zendframeworkbook/en/1.0
Take Care,
Mert
(sorry for my english)
Thanks for the link, it looks like an interesting read. Hopefully it
will help me understand MVC better and hence allow me to improve my code
design.

Hi everybody!
I want to get some tips about how avoid a attack of Denial of service. May
be somebody can about your experience with Php o some configuration of
apache, o other software that help in these case.
Thanks in advance.

Not sure what exactly you are looking for.
Anyways, some common practice are request for API key, username / password
tokens before providing access to a service.
Thanks,

If you are using Apache there are a bunch of different DoS modules that
you can use:
http://www.google.co.uk/search?q=apache
+dos&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a
Also, if you are in full control of the server, you may be able to
configure firewalls for this sort of thing.
It gets more complex when you're attacked with a DDoS (Distributed
Denial of Service) as there's no real hard-and-fast way to prevent them,
as they could genuinely be legitimate requests to your server and not
attacks. As a distributed attack comes from many sources, you can't
reliably differentiate the valid requests from the malicious ones.

Hi guys,
I've knocked up a quick RSS feed on my site. It works fine in Fx 2 & 3,
in Opera it throws an error "unexpected end of file" but allows the feed
to be added anyway, and Chrome just says there's an XML error, and gives
the second from last line as the one containing the error.
I tried adding a newline to the end of the file, but that just makes the
error message report the next line. Any ideas where I'm going wrong? The
file is using utf-8 character encoding.
Thanks,
Ash

Nevermind, I was having a "moment"! I'd forgotten to close the final
tag, as I mistook the root <rss> tag for an XML declaration instead! I
am a little surprised that Fx allowed it to validate correctly though!

Well, don't forget, Fx will correct SGML and HTML that is missing tags.
I think Fx would rather simply accept the incorrect format, correct it (since it
wasn't a fatal error), and finally display what it figures you /intended/ to
send it.
I hate it when software tries to assume what I meant to say... :-(

I'm just used to it letting me know if I was trying to view malformed
XML. It must be a special case for RSS as it recognises the format as
being special!

Hello all,
I'm grabbing all records from a table using:
$records = $stmt->fetchAll(PDO::FETCH_OBJ);
return $records;
In order to display the values we can do:
foreach ($records as $record)
{
echo $record->id;
echo $record->name;
}
However, I'd like to grab, also, the *column names*.
I've tried:
foreach ($records as $column=>$value)
{
echo "$column is $value\n";
}
But I get:
"Catchable fatal error: Object of class stdClass could not be converted to
string"
Can I have your help on how can I properly get the column values?
Regards,
Márcio

I feel like a total newb asking this, but I'm just having a brain fart or
something...
I'm writing a page where I can either get back a list of items:
Array {
[1233] => "apple",
[6342] => "apricot",
[2345] => "banana",
...
}
where the user then refines it by choosing one single item and a single
element array is returned like this:
Array {
[8575] => "peach",
}
How can I get this $item so I can print it like so:
echo "The ID is $id and the name is $name";
Normally with an array of items, I do a:
foreach ($item as $id => $name) echo...
But that seems overkill for this scenario.
The rub is that I don't know the "id", so I can't use $item[0], and I also
don't have something like $item['name'] to use either.
There's got to be an easy way to extract those.
list($id, $name) = $operator;
Felt like it would work for a minute (wishful thinking).
(I'm too embarrased to even sign my name on this one)
