Re: [PHP] 304 Not Modified header not working within a class
Camilo Sperberg wrote:
Hi list, my first message here :)
To the point: I'm programming a class that takes several CSS files, parses,
compresses and saves into a cache file. However, I would like to go a step
further and also use the browser cache, handling the 304 and 200 header
types myself.
Now, what is the problem? If I do it within a function, there is absolutely
no problem, everything works like a charm. However, when I implement that
same concept into my class, there is no way I can send a 304 Not Modified
header, when the data is *over* ~100 bytes.
Hi Camilo
For what it is worth I have implemented cacheing in a class and for me
the 304 not modified header gets sent fine ... some example headers
output is below together with the relevant code snippet..
// See if client sent a page modified header to see if we can
// just send a not modified header instead
if (isset($_SERVER['HTTP_IF_MODIFIED_SINCE']) &&
$_SERVER['HTTP_IF_MODIFIED_SINCE'] == self::$_gmmodtime) {
header('HTTP/1.1 304 Not Modified');
return null;
}
if (isset($_SERVER['HTTP_IF_NONE_MATCH']) &&
stripslashes($_SERVER['HTTP_IF_NONE_MATCH']) == self::$_etag) {
header('HTTP/1.1 304 Not Modified');
return null;
}

Re: [PHP] Re: PHP Application Structre
On 10/05/2010 18:17, Ashley Sheridan wrote: It makes sense sometimes to have different files for different sections of a website. For example, blog.php, gallery.php, cart.php could deal with the blog, gallery and shopping cart sections for an artists website. Yes, it could all be achieved with one script handling everything, but sometimes when the areas of the site differ greatly, it results in a lot of extra code to deal with pulling in the right template and content parts. I've always favoured only including the code a page needs rather than a huge amount of stuff that it doesn't. this isn't necessarily true - the architecture I've developed uses a single dispatch script (works fine with the mod rewrite option 2 scenario as well) - this script does general checks/security/filters etc then simply determines what page/function the user wants from the request ($_GET/$_POST parameter) and passes control to the specific handler via including the relevant controller module. The controller module is responsible for which template is required and loads up specific classes needed to process the request etc so each module just loads its own stuff and nothing else so there's no overhead. This method also has a small extra benefit that the web server document root just has a very simple 2 liner script instead a myriad of php scripts... if the webserver is misconfigured then someone who sees the source code doesn't get to see much..

Are you are using a 'referencing' foreach? i.e.
foreach ($objs as &$obj) {
do_some_stuff($obj);
}
or is the above code a direct lift from your script?
Referencing foreach statements can cause problems as the reference to
the last array entry is persistent after the foreach loop has terminated
so any further foreach statements on the same array will overwrite the
previous reference which is still pointing to the last item.

throwing everything starting from "da08.." away.
That's a very different proposition, and probably has more to do with word
size: float is 32-bit, so only the first 32 bits are used and if anything else
is found the conversion falls back to INF. To handle really big integers like
8315e839da08e2a7afe6dd12ec58245d you probably need a more specialist library
(or language)
For me it is not. PHP throws things away during conversion. In my opinion a
language (compiler, interpreter whatever) should not do that. Never ever!
Either it is able to convert the value or it is not.
What about of returning "null" instead of "0" if the conversion is not perfect?
So intval('F') could return NULL and intval('0') could return 0.

Daniel
I think you will have to live with this or use another language for
development - IMO it will never change because of the massive BC break
that would be produced by changing the type juggling behaviour... of
course you could always post an RFC to the dev/internals list if you
want to take this further... good luck with that!

a field named 'varenr' exists in both tables - your sql query needs to
specify from which table you are selecting the data.
foreach($varenr_inn_pa_lager as $vnr){
include('../../tilkobling.php');
$sql = "SELECT * FROM exan,dynamit WHERE varenr = '$vnr' LIMIT
do you really need to include the file 'tilkobling.php' repeatedly for
each iteration over $varenr_inn_pa_lager??

Re: [PHP] Re: $_POST variable
You could use foreach to iterate through the post variables until you
encounter a match:
foreach ($_POST as $key => $value){
if (substr($key, 0, 6) == "radio_") {
$buttonName = $key;
$buttonValue = 4value;
break 2;
}
}
I haven't tried the above code, but I hope someone will correct my
efforts if I'm wrong.
given your code example -> 'break 2;' -- s/b just 'break;' ... 'break
2;' is to exit the outer loop of a nested loop which is not the case here.
