Hi,
I am on a quest for a new good webhost and I am currently using a trail
account at a host that seems pretty good, but has one problem. I cannot
turn register_globals off. They don't allow php_flag/php_value in
.htaccess for security reasons but in this case it's causing insecurity
... hi Karen, I notice you're (probably) dutch, that given I might recommend
http://webhosting.nedlinux.nl - always been very good for me.
Marc (the owner) is very generous guy (for instance he runs a php, myql
& gentoo mirrors). as a php programmer I have never been left wanting
for functionality..i.e. you want registers globals off on your site,
you got it.
klein maar fijn. :-)
Thanks a million!

Hi,
I have a table with 15 columns or so that has been inherited from an older
db and am trying to insert an auto increment column (in mysql) without
having to number it manually. This is fine when I add new colums via a form
but the old entries have a null value
Alternatively It has been converted from Excel soif anyone knows how to do
it that way that would help.I never use Excel so have no clue about it.
R.
$id = 1;
do {
mysql_query('update table_name set id = ' . $id++ . ' where id is
null limit 1');
} while(mysql_affected_rows() > 0);

Yes, I completely agree that business logic should be separated from
presentation logic. Only problem I have is that from there people go on to
conclude that html does not need to be sseparated from presentation logic.
As far as I see It is a very good idea to keep all 3 of them separated.
Bussines logic from presentation logic by proper organization and code
design in php, and presentation logic from html by template engine.

What usually is the problem is that template systems define its own
programming language, with constrructs for loops, if's and whole other bunch
of stuff to model dynamic behavior. And I agree with you that this makes
diffrence between using such template system, and just php as template
system much, much smaller.
Where I do not agree, is that "fat template" syndrom is common to all
template engines, and that it is inveitable. For instance my TemplateTamer,
is now almost 5 years old, and it never had any sign of becomming
programming language in it self, and it never will. It has a markup language
of only 6 idioms:
<!--NAME: -->
<!--END: -->
<!--GLOBAL: -->
<!--USEGLOBAL: -->
{VARIABLE}
{#TRANSLATE}
and there is no single sign of presentation logic inside html template, no
ifs, no loops, no calls to the methods or functions, nada. All presentation
logic is written in php, and in nicely separated logic.php file.

The DOM implementation i PHP5 allows classes to be extended. Extending
the Document class is no problem, but how can I extend the Element class
and use it in a DOM tree?
DOMDocument::createElement returns a DOMElement object which you cannot
extend.
Could this be a solution?
class MyElement extends DomElement {
function __construct($a_stTagName) {
//has to be called!
parent::__construct($a_stTagName);
}
function myFunction() {
// do something
}
}
$oDom = new DomDocument();
$oMyElement = new MyElement('mytag');
$oMyElement = $oDom->importNode($oMyElement, true);
$oMyElement = $oDom->appendChild($oMyElement);
Regards

Ok, that was not the really right answer ;) Of course it does work.
You can even do stuff on that element, if you use the variable, resp.
reference ($oMyElement) for doing this.
What doesn't work (and I referred to that) is getting this object
back from the DomDocument, so for example:
$oDom->documentElement will give you the DomElement back and not your
new MyElement.
Hope it's a little bit clearer now

But all the chinese words could change to "????". The charset of this

I wonder know how to deal with it. And i am blind with it now. Because
the lack of experience with php.
Maybe UTF-8 is not supported by your system. You may try GB2312 to see
what happends.
Good luck.

i've been doing some reading on optimizing php for fastest performance.
are there any benifts to configure php with:
--enable-inline-optimization
also running eAccelerator.
these are my current options:
--with-apache=../apache_1.3.33 \
--with-mysql=/usr/local/mysql \
--with-xml \
--with-gd \
--with-jpeg-dir=/usr/lib \
--with-png-dir=/usr/lib \
--with-xpm \
--enable-magic-quotes \
--with-pear \
--enable-gd-native-ttf \
--with-zlib
just looking for tips.. that is all.

That's the default now, so no, you don't need that.

That's a bit of a hassle for you, I bet. You have to recompile Apache
to upgrade PHP. You can get the same performance by using --with-apxs
to get a shared library and --without-pic to make sure you get a non-pic
library. For older PHP versions, --without-pic won't work and you need
to hack your configure scripts a bit. Just change all instances of
-prefer-pic to -prefer-non-pic. Or use this patch:
http://www.lerdorf.com/php/non-pic.txt
You can tell if it is working by looking at the compile line as it is
compiling. If you see -prefer-non-pic instead of -prefer-pic on each
line it is working.
--with-mysql=/usr/local/mysql \
--with-xml \
--with-gd \
--with-jpeg-dir=/usr/lib \
--with-png-dir=/usr/lib \
--with-xpm \
--enable-magic-quotes \
--with-pear \
--enable-gd-native-ttf \
--with-zlib
just looking for tips.. that is all.
Beyond the compile-time switches, look at your configuration. Check
your variables_order and turn off $_ENV population. That is, remove the
'E' from variables_order and look for any $_ENV instances in your code
and change them to getenv() calls.
Also, remove '.' from your include_path and always use:
include './foo.inc';
That will save you a system call on every include. At the same time,
for the real include_path includes, make sure that most of your includes
hit the first include path. If PHP has to scan multiple dirs on every
include it will be slower than it needs to be.
But most of your gains will come from profiling your actual code using
either apd or xdebug and optimizing the parts that show up as being the
bottlenecks.

Hey,
I know this belongs more on the mysql list, but I'm not a member there and I
dont often have problems queries plus dont have time to join then ask just
this one q and then unsub...so if possible please help :-)
I have these two tables:
jappz_guestbook(owner_cno, sent_datetime, is_secret, accepted)
jappz_member_profile(cno, pic_name)
jappz_guestbook's owner_cno and jappz_member_profile's cno are the same
what i need to do is select * from jappz_guestbook where owner_cno=x and
also select pic_name from jappz_member_profile where cno=jappz_guestbook.cno
I have been fooling around with something like this:
SELECT * FROM jappz_guestbook
INNER JOIN jappz_member_profile ON jappz_guestbook.owner_cno =
jappz_member_profile.cno
WHERE jappz_guestbook.owner_cno = jappz_member_profile.cno;
but its not working, how do i get the pic name from the other table
(jappz_member_profile)?
Thanks,
Ryan
