Hi,
i still got no answer. Maybe i did not see it, altough i'm trying to read any
single post. But may be i overlooked it due to high traffic. So now i have
set up a filter (hopefully) copying answers to another folder.
Here is the question: Is it possible to disable validation when using
XSLTProcessor? If yes, how?
When i use xsltproc, the command line tool for the libxslt, i can use the
switch --novalid to subpress validation. This makes a huge difference in
speed. Without validation it is fast enough. With validation it takes far too
long to be acceptable. So how do i use XSLTProcessor from within PHP to
achieve the same result as if using xsltproc --novalid?
Regards
Siegfried

You may want to try using http://php.net/exec to run your command line
tool and ignore the PHP one, if it won't let you turn off validation.
You could also consider filing a "Feature Request" in

the engine doesn't give 2 hoots about what you think it should be of course.
'static' doesn't do what you think.
chances are you want to use a private instance property:
<?php
class Foo {
private $i = 0;
public function bar() {
echo $this->i, "\n";
$this->i++;
}
}
$a = new Foo;
$b = new Foo;
$a->bar();
$a->bar();
$a->bar();
$b->bar();
$b->bar();
?>
do please read the OO sections of the manual, some functionality, although named
similarly to other languages, works quite differently - you'll avoid alot of assumption
biting you in the a$$.

thats a gamble since there is no description of how the static keyword
behaves inside class member functions. i for one will stick to static class
variables and instance variables, and avoid this static variable feature
altogether.

Just FYI the static keyword was quite popular in PHP4 for the
singleton pattern. You could do something like:
function getInstance() {
static $instance;
if (empty($instance)) {
$instance =& new Instance;
}
return $instance;
}
I've used it across multiple classes without any real conflicts so it
was fine. Of course I wouldn't do such a thing now that I am working
in 5, but I just thought I'd throw that out there.

and im certain it was used heavily that way in php4 as well. its also
great for those people who dont want to use classes in their php.
i mainly avoid it as a matter of preference. all im saying from earlier,
is that even if it does work inside class methods, theres no doc out there
that gives the green light on such usage (at least not to my knowledge).

static variables save your scripts repeating themselves..
class used_all_over_the_place {
private static $bigArrayOfThings;
public function __construct() {
if (!is_array(self::$bigArrayOfThings)) {
$this->complicatedMethodThatFormsArray();
}
}
protected function complicatedMethodThatFormsArray() {
#loads of stuff that would be best not to repeat to often
}
}
#complicatedMethodThatFormsArray is called here
$myclass = new used_all_over_the_place;
function something() {
#complicatedMethodThatFormsArray is NOT called here
$myclass = new used_all_over_the_place;
}
maybe I've gone ot or missed the point of this thread..

There's something wrong with re-usable components that are extended as
separate classes? Weird, I thought that was half the purpose of OOP.

Yes and yes...
Tho I suppose you might have some "extra" info in the replicated DB
about the user that would not be crucial to be up-to-the-second
accurate that could be considered part of your "session" data...

It can "help" reduce the amount of cross-server data, but it's not a
solution since a user could have multiple IP addresses in a single
session, and multiple users could have the same IP address.

There is some kinda signal you can send to Apache to GRACEFULLY die out.
New connections are refused, but old ones are finished and then the
child exits.
http://apache.org/
There is a "graceful" restart for sure. Perhaps it's just "apachectl
graceful stop"???

the problem with the AJAX approach is the fact that there is absolutely
no reason for a user to sit staring at the screen. hit 'Go' get an
email when it's done, do something else in the mean time.
of course a PHB might demand functionality that gives him/her an excuse to
watch a progress bar ... in which case why not waste man hours making it a
funky web2.0 deal ... heck go the whole hog and use 'comet technique' to
push update info to the browser.

You can use a resized window (JS required) which automaticaly
refresh all 2 seconds and show the status of the taring...

Can't see any problem with going down the ajax route myself (depending
on how many concurrent users you expect) - A simple ajax style poll
every second would suffice.
You could always use the fancily named yet really old "comet technique"
aswell.. slap the script in a "magic" iframe and ob_flush whenever you
have new data to send.
To be honeswt, both are trade-offs on a technology which isn't around
yet. With ajax you've got to spawn a new thread for every request (say 1
per second, 100 concurrent users, that's 100 requests per second minimum
on your server) OR with comet you've got 100 long lasting worker threads
going.
If you do go comet, it's worth investigating mod event for apache 2.*

in the last couple days, i've looked into php $_SESSION and kinda get the
concept. my question is can i use $_SESSION to store mysql statement?
what is the pro/con to store mysql statement in $_SESSION?
with $_COOKIE, i can use setrawcookie to avoid urlencoding. is ther
anything similar in $_SESSION?

Hiep,
There is no need to use "setraw" in case of session. Because every
session variable keeps its value as it is assign to it. Where as in
case of cookie by default browser encode the cookie in urlencoding
format. To stop this feature of browser we use setrawcookie() function.

You can easily store a SQL statement in $_SESSION since the statement
is just a string. Are you asking if you can store the *result* of the
statement execution in $_SESSION?
You shouldn't store the SQL statement in cookies. It gives the end
user way too much insight into your DB implementation if they can see
the actual statement that you will be issuing to the database and it's
an even bigger security risk for SQL injection than simply using raw,
unescaped form input in a statement without validation! The attacker
doesn't even have to think how to create a parameter to escape out of
your statement - they can send you "DELETE FROM mysql.user" or any
other wonderful thing they like. Granted, your script should not be
using a db user account that has privileges to execute such a
statement, but that should give you a clue that this would be a VERY
bad idea.
URL encoding/decoding isn't really an issue with sessions since the
session data is stored internally on the server and does not have to
be urlencoded to be sent between the server and the browser in an HTTP
header.

I think the best way is to have a local MTA (e.g. postfix), to which
mail()/sendmail can simply drop emails in the filesystem.

Often times, you can write a tiny shell script to connect using an
authentication password to the mail server, and then the rest go
through as you are already authenticated...
Not sure this applies to TLS/SSL, but it's worth a try.

Having seen your sample code, it probably IS within the PHP code,
since you are passing a file handle to curl -- and it should behave as
a proper file handle, in an ideal world, as far as curl is
concerned...
But then curl may be doing something funky with it and making invalid
assumptions too...

Scanning for SQL injection is like a "blacklist" approach -- always
bound to be another injection you didn't think of.
Validating the data and using mysql_real_escape_string is the
"whitelist" approach -- You specifically require the data to be of the
correct format, and you get MySQL to delimit it properly as DATA and
not SQL CODE.

Old-school PHP functions do not (and will not) raise exceptions.

If you do a Location: with a FULL URL then the browser will forward
POST and I think AUTH data.
If you use a partial URL, it seems to work, but IE will decide not to
forward that data.
It is in the spec that you need the full URL, starting with http://
for a Location header.
This may (or may not) be what is messing you up.
