[PHP] parsin XML with DOM
hello, could somebody give me some direction here. i am trying to build a RSS 2.0 parser using DOM. what puzzles me is the following - i get the XML - $RSS_XML = file_get_contents($params['uri']); then i instantiate a DOM object - $RSS_DOM = new DomDocument(); then i load the XML - $RSS_DOM-loadXML($RSS_XML); then i get the first node - $NODE = $RSS_DOM-firstChild; here $NODE-tagName is rss, so far OK but then if i get the first child of rss, which is channel - $NODE = $NODE-firstChild; its type is not DomNode, but DomText. Only the 2nd child - $NODE = $NODE-nextSibling; has $NODE-tagName channel. My question is - why is the first child after rss DomText?

[PHP] generate letter combination..
i made a mistake when i say i can solve this problem to a friend. finally i realize it is not as simple as i appear to be. what he ask me to do is write a simple script that, given a word.. the script will generate a list of words combinaton from the each character in in that word. i am tired thinking. to make it clear. i give a simple scenario. i don't have an idea what i should name my baby. so, i took my wife name and me and input to the script.(i want a name that is from our name combination). later the output will present many words that i can choose. the input string can be of any length. anyone have an idea?

Re: [PHP] Disadvantages of output buffering
These two reasons are in fact of little impact. The real problem I have with output buffering in my web app is that it doesn't handle .xls and .pdf files generated on the fly with PHP. Every time the browser is going to download those kind of files it will get corrupted. The only solution I could find for this was to disable output buffering. Another thing: you can even compress the buffer before sending it so it will help a lot if a user have little bandwidth. Text files have a very good compression ratio.

[PHP] DOM support
Hey! I have been looking through the docs writing test code and am going a little bit mad trying to work this out. Does anyone know where I can find a definitive list of DOM XML functions that are supported in specific versions of PHP? I write my code in Zend and it has 5.2.0, so everything works as per the manual but when I try to run on our production environment (5.0.4) then things go very, very wrong. In particular there doesn't seem to be a DOMXPath object. Failing a list of methods/versions - does anyone know what I can use in lieu of a DOMXPath object?

put together some names, phrases, and other stuff expressed as PHP

?
while($u_work) {
whistle();
}
?
would be Whistle While You Work.
Try to use some really common phrases that all of us around the
world should recognize, but feel free to get really elaborate with the
code.
So here's the first one (it's simple):
?
function at($level) {
$level == 10 ? $ret = winner : '';
$level == 15 ? $ret = try : '';
$level == 20 ? $ret = first : '';
$level == 25 ? $ret = user : '';
$level == 30 ? $ret = place : '';
$level == 35 ? $ret = again : '';
$level == 40 ? $ret = succeed : '';
$level == 45 ? $ret = last : '';
$level == 50 ? $ret = finish : '';
return $ret;
}
if(at(20) != succeed) {

Thus, if his script is terminated before his code deletes the file, the engine will insure it's deleted. Otherwise, he should use an ignore_user_abort(). You're right, and good point about ignore_user_abort();. I'd actually never used that function before, but there are several places where I could (and probably should). The point I was making is that, unless the server is set up properly, as the files exist on the server, they'll be readable, clone-able, and possibly even executable. All a malicious user would need to do is watch the /tmp directory for files being written and immediately copy or read them. This doesn't take into account proper usage of suexec, correct chmod'ing of /tmp (and mounting, if you're like myself), et cetera, but keep in mind that not all (perhaps even most) hosting providers out there are one-man operations, and a gross majority of those are run by people with almost no knowledge of - or maybe concern for - best practices regarding their customer's security. -- Daniel P.

put together some names, phrases, and other stuff expressed as PHP
code and see who can come up with a real stumper. For example:
?
while($u_work) {
whistle();
}
?
would be Whistle While You Work.
Try to use some really common phrases that all of us around the
world should recognize, but feel free to get really elaborate with the
code.
So here's the first one (it's simple):
Yes, of course, call it simple... :P It took me 20 minutes to figure
it out :S :P
?
function at($level) {
$level == 10 ? $ret = winner : '';
$level == 15 ? $ret = try : '';
$level == 20 ? $ret = first : '';
$level == 25 ? $ret = user : '';
$level == 30 ? $ret = place : '';
$level == 35 ? $ret = again : '';
$level == 40 ? $ret = succeed : '';
$level == 45 ? $ret = last : '';
$level == 50 ? $ret = finish : '';
return $ret;
}
if(at(20) != succeed) {
try {
$e = again;
throw new Exception($e);
} catch(Exception $e) {
echo Try .$e-getMessage().\n;
}
}
?

True, but on an unsecured box, this becomes possible, as Apache

writing to the /tmp directory. This includes session information,
temporary .php files (as Marius requested), et cetera.
Proof of concept:

[PHP] Problems with mirror site script
Hi.
I am currently writing a script to put on my site so people can browse
other sites by using my site as a mirror therefore the contents of a
webpage would be retrieved and echoed on my site.
I am having some problems with placing my ad at the top of the page
that is echoed when a user browses a site so that it doesn't interfere
with the headers. I am having problems with where to place the link
e.g. after the body tag, and how to find out what type of page it is
i.e. html, xhtml, etc. so I know if I can use specific effects with my
ads.
Also, when a user clicks on a link on the mirrored page the link
should be mysite.com/index.php?go=http://othersite.com/othersitepage.htm
and not mysite.com/othersitepage.htm
I have tried to use str_replace in the contents of the retrieved
webpage but it doesn't seam to work.
Here is the simple piece of code that I have started with without security etc:
?
// $http is the page that the user wants to browse
$handle = fopen($http, r); ///get contents of webpage
$contents = fread($handle, 50);
fclose($handle);
$replace = explode(mysite.com/, $contents);
str_replace(mysite.com,
mysite.com/index.php?http=$http/$replace[1], $contents);
if(strstr($contents, !DOCTYPE html
PUBLIC \-//W3C//DTD HTML))
{
$ads = ads_html();
$contents2 = explode(/body , $contents);
}
if(strstr($contents, !DOCTYPE html
PUBLIC \-//W3C//DTD XHTML))
{
$ads = ads_xhtml();
$contents2 = explode(/body , $contents);
}
echo $contents2[0] . $ads . $contents2[1];
?
Please advise me if there is another better way to place my ad and
check the type of page because this coding is just wrong and
error-prone.
Thanks

Re: [PHP] Aggressive PHP Smart Caching
Thank you for your reply Nathan. You are right that this method of caching is different than the two types you have outlined below. I would not say that it is a new method though, in fact, pushing static files to the server is very common. If it weren't for the fact that this method, as I have designed it, allows a very tiny PHP overhead to handle dynamic updating of the cache I could have even gone the extra mile to push html files that would be loaded directly by the end user without PHP being initialized at all. (My reasons for not taking this last step should become apparent to those who read the wishlist I produced at http://technologies.babywhale.net/cache/ ) Understand that this method does not *exclude* using the other two methods you have outlined. In fact, I personally make use of memcached and APC where I feel it is appropriate in my application design. This does not mean that I can not also write a cache layer that makes the application itself and its variables irrelevant and not required for most site hits (hence a major optimization). To answer your other questions: 1) Caching on disk could easily be handled instead by caching in memory, but this approach is meant to be ultra-portable and work everywhere. There are situations where a viable memory storage mechanism is simply not available, and other cases where it is not desirable to consume memory for this purpose and plenty of hard drive storage space is a good alternative. I think you will find this caching method is intensely speed-tuned and a fast implementation of a portable file system based method. I would also point out that in my line of work, where I chiefly have to adopt environments that are configured under rather political circumstances, it is consistently this type of caching that the system administrators argue for. As someone has already pointed out, there may not even be a significant difference between disk and memory based storage mechanisms on your server. 2) Again, one of the main theories behind this method is portability. In order to not rely on cron, server queries, or other external checks for a stale cache, I have gone with a refresh interval which has been proposed on this list in the past. It proposes that dynamic content should be refreshed once every X seconds/minutes/hours. This script avoids PHP date manipulations and instead performs some basic math to handle the refresh rate, but also to *sync* content to some degree, so portions of dynamic content are less likely to haphazardly refresh independently and therefore not match. I think this is a slight improvement over code that has been posted here before. In a practical sense, this means that your application fires and produces content only once every X minutes, and not each and every time the page is hit. Furthermore, because in this case it is known ahead of time when that page will expire, a cache header can be sent with an exact expiration time so repeated hits by the same end user will not even trigger a transmission of cached content from the server. 3) In regards to daily purging: for one, if you are going for a scheduled refresh of content, then you probably already have a refresh rate that is less than 24 hours, so accepting an additional daily trigger of recaching should not be unacceptable. But more specifically, the reason behind this is that a file system based caching method does not natively support a TTL on cached files, and there has to be some way to handle a cache of a script that has since been deleted. Note that if 24 hours is not acceptable for some reason, this script can easily be modified to increase that without negatively affecting anything else.
