'processing' JSON formatted data is a matter of running a single eval()
line in javascript!?!
just outputting HTML directly into a div is useful in many simple
situations but it doesn't leave a whole lot of room for any real client
sided application logic ...
All that "client side application logic" can also be done in PHP.
Where's the sense in learning to work with JSON, if it can be done in
PHP too? PHP is a lot faster then javascript right?

I've did a few test on this PC(AMD64 3200+), it's running EasyPHP
(Apache+PHP+MySQL), and it shows me that PHP is about twice as fast
then Javascript.(Tested using IE6, FF wasn't working because script
took too long to execute, which generates messages on firefox, and
which didn't let me finish the script)

Fine, just switch the order you are adding them to the two different arrays.
instead of this:
$find[] = '$pay_rate';
$find[] = '$pay_rate_bap';
$replace[] = $pay_rate;
$replace[] = $pay_rate_bap;
do this
$find[] = '$pay_rate_bap';
$find[] = '$pay_rate';
$replace[] = $pay_rate_bap;
$replace[] = $pay_rate;
find the longer one first
I guess next I will play around with preg_replace, but I'm thinking I will
have the same problem as I did with str_replace... As long as the variable
names have any kind of similar names.... Correct? I can resolve this I
suppose, but the data is already in place and trying to work around it...
Thanks,
Jake

Hi everyone,

If I read the manual correct about how to setup the input
values for str_replace()
you should be able to do the following.
This is completely untested, since I have now system like
yours. But here is goes...
#setup the entries that you want to find.
$find[] = '$name';
$find[] = '$ppe';
#setup the values to be replaced.
#Mind you to keep the indexes the in sync with $find...
$replace[] = $name;
$replace[] = $ppe;
echo '<pre>';
while ( $row = mysql_fetch_assoc($resultHandle) ) {
$row = str_replace($find, $replace, $row);
// do something with $row. Display it maybe...
var_dump($row);
}
echo '</pre>';
Basically replace $find[0] with $replace[0] in any of the
values of the return $row then replace the
previous $row values with the newly modified values...
Then go to the next index of $find[1] and
$replace[1] and do the same thing until you are out of indexes.
But this is a much better way of doing this than using
eval(). eval is an evil little function!

same is true for the parameters. don't use references unless you need to -
namely when you expect to actually change the passed in value.

it remains bad if there is another way to do the same thing. eval() is the
matchete you use as the last resort when your backed into the corner by a group
of hungry zombies ... unless you have a zombie problem keep your machete
holstered ;-)
having absolute, total and complete control over the input to eval() is the
entry price for even thinking of using it.
ok this is slight scare mongering but the fact remains: eval() is capable of
causing you serious damage and it's also comparitively slow!

Dear All,
I have made a tabbed navegation with CSS. And if you set class="active" to
one of the tabs, it will then be highlighted.
So I thought to make this dymamic with PHP. Using the $_GET variable I can
get the page name above with something like. $page_name = $_GET['page'] ;
so I can tell the class when to be active to what page.
Should I use the isset function for this? I am very new to PHP but here is
my try, but of course its not working:
<?php
if (isset ($_GET['page'])) {
$page_name = $_GET['page'] ;
if ($page_name = "default") {
$flg_page_default=1;
}
if ($page_name = "about") {
$flg_page_about=1;
}
}
?>
<a <?php if(!isset($flg_page_default)) echo 'class="active"'; else echo '';
?> href="index.php?page=default"><span>home</span></a>
<a <?php if(!isset($flg_page_about)) echo 'class="active"'; else echo ''; ?>
href="index.php?page=default"><span>about</span></a>
Of should I stick to just static html :(
Dwayne
Close, but this is probably how you should do it
$links = array();
url display
$links['default'] = "Home";
$links['about'] = "About";
etc...
foreach($links AS $url => $text) {
$class = '';
if ( isset($_GET['page']) && $_GET['page'] == $url ) {
$class = ' class="active"';
}
echo "<a href='index.php?page={$url}'{$class}><span>{$text}</span></a>\n";
}
This will allow you to change one piece of code, instead of twenty lines later
on.
Use a little of the DRY principle.

Hello,
I would like to install pOWL
(http://aksw.informatik.uni-leipzig.de/Projects/Powl) with ORACLE. I obey
the installation steps. I log in:

and then then i get this error message
http://www.picvalley.net/u/26/25124_335.PNG
How can I find out what causes the mistake? There are several php files,
however, I am not so fit in php and cannot find the error. If I use pOWL
with MySQL instead of ORACLE, everything works perfectly. I think, i must
change something here: http://www.nabble.com/file/7585/include.php

Something went wrong with installation i think.
You should check that the database testdb exists.

Hmm, in your image i see Database 'testdb' not found. Followed by a
link. What happens if you click on that link?
I don't know anything about Oracle/pOWL, but it looks like the script
can't connect to your Oracle database. Did you check if the database
settings are correct?
Like I said i don't know anything about Oracly, i use MySQL, but it
requires a host, username, password too i think, so you should check
if these are correct.

The click on the link is the next step - this create some tables (but for
this i must change the querys first). pOWL is using the ADODB, and i have
made small script, witch make connection via ADODB and execute select query
(see this: http://www.nabble.com/file/7587/adodb_test_oracle_connection.php
adodb_test_oracle_connection.php ). This works perfectly....the result:
Array ( [0] => 1 [MODELID] => 1 [1] => http://powl.sf.net/SysOnt/0.1#
[MODELURI] => http://powl.sf.net/SysOnt/0.1# [2] => [BASEURI] => )
Have someone another idea, how to solve the problem?

Jake:
As I stated, not all browsers support alpha channel images.
Unfortunately, IE 5.5 and IE 6 fails while everything else (including
IE 5.2 and IE 7) passes -- just another example of why people should
use a different browser than IE 5.5 and IE 6. In fact, just consider
using *anything* but IE (IMO).
See below screen-shots:
http://www.browsercam.com/public.aspx?proj_id=336219
Everything that has a blue dot works AND everything except for IE 5.5
and IE 6 has a blue dot.

I know that I can provide hidden text that bots can see but users
can't -- as demonstrated by this:
http://www.webbytedd.com/examples/offleft/
As such, I wonder if that may provide a twist to this. However, it
would only exist for sighted users.
I think that what Steve suggest may have some merit. I need to
think of some examples.

Would you be able to name a text field something really common like
"e-mail", place it off screen and then check to see if a certain
value is in there and if not don't submit the form? I remember
someone somewhere doing that.
Such as prefill the that text field with [EMAIL PROTECTED] and if it has
anything else reject the form?
Yeah, that would be the idea -- I was just trying to fathom some
really clever way to use the technique -- forgive me I'm strange that
way. My brain works are different.
Cheers,
tedd

Jake:
As I stated, not all browsers support alpha channel images.
Unfortunately, IE 5.5 and IE 6 fails while everything else (including
IE 5.2 and IE 7) passes -- just another example of why people should
use a different browser than IE 5.5 and IE 6. In fact, just consider
using *anything* but IE (IMO).
See below screen-shots:
http://www.browsercam.com/public.aspx?proj_id=336219
Everything that has a blue dot works AND everything except for IE 5.5
and IE 6 has a blue dot.

I remember that from the Invison Board version 2.1.0 and above. They
also use Alpha PNG images. But they have some kind of javascript
function that fixes that, atleast that's what the comments say. I
don't know how it works but you might want to take a look at it. AFAIK
it is only using Javascript, so you would be able to see full source
code :)

Unless you made a failure behave similar to a success but put them
in a situation where ultimately they still can't post messages or
access anything useful.
I remember reading about either 3D Studio or Maya (one of the 3D
modeling programs) and their copy protection method. They, at one
point, made I guess an obvious segment of code for the software
pirates to 'crack' that appeared to have totally deprotected the
program. It turns out that it only sort of de-protected it. They
put in multiple mechanisms that were more subtle. The one I'm
thinking of apparently made it so that after 250 right mouse clicks,
it would render everything in lower and lower qualities of
rendering. Or not render at all. OR menus stopped working or
something. But it was something that wasn't obvious at all until
people really started using the pirated copy for a while.
Tricky bastards. I love it. hah
-TG
Yeah, me too!
In one of my applications, I put in a self-check for size. If anyone
change a single byte, the program crashed.
In the old Apple days, I knew one developer who wrote a program that
when it thought is was being altered initialized it's floppy -- it
bit harsh I think. :-)
I wrote one that when altered would continue working, but gave the
wrong results. I was amused when people would contact me and complain
about their pirated copy not working properly.
I wrote one, didn't mass release it, but if it detected alteration,
it would send me an email telling me where it was and other specifics
about the user. I thought that was kind of neat, but it violated
privacy issues I wasn't comfortable with. However, I could have init
their hard-drive if I had wanted. I wonder what affect that technique
would have on pirating software.
Oh well, enough off-topic chatter.
Thanks for all the review and comments.

This kind of protection is still used these days. A cracker could
atleast use programs like SoftICE to temporaly change bytes. And then
he only needs to find where that protection exists and break that too
:)

That's a good one :)

Yeah, privacy issues.... They suck.. LOL. You can only try to create
programs that are unbreakable, not that send you information about the
cracker. The nicest thing to do is just making applications that
format ur HDD when changing a byte :) If a hacker just does a first
try, then clean up the HDD :)

Hi all, i've got apache/php4 running on windows xp with good hardware
configuration etc. However, the speed of execution of php pages is really slow.
When testing on my local development machine it takes a few more seconds
executing php files than it should normally take.
How can I up the speed of execution ? is this possible ? On my hosting
server its really really fast ! and I will like the same settings for my local
machine as it has a very good hardware configuration and memory.
cheers
