Hi everybody!
I use cake, I have an error, but I can't find where the error occurs.
Have any tools for debug?
Set up an error log. Edit your php.ini file and set:
log_errors = On
error_log = /path/to/logfile.log
then errors will get put in the logfile and you'll be able to track them down.

Since / is your delimiter you need to escape it.
Also '.' means anything so you need to escape that as well.
if (preg_match('/\.\.\//', $string)) ...
What are you trying to achieve? There may be a better way than using a
regular expression.

You're right, it's not going through the __Set() method a second time.
If you REALLY want to get confused by overloading behavior try the
following code using your T class:
$t = new T;
$t->insideArray = array('a' => 'A', 'b' => 'B', 'c' => 'C');
foreach ($t->insideArray as $k => $v) {
$t->insideArray[$k] = null;
}
if (count($t->insideArray) > 0) {
foreach ($t->insideArray as $k => $v) {
echo $v;
}
}
var_dump($t);
Why does count() return > 0?
Why has $t->insideArray become NULL instead of an empty array?
I can't tell you because I don't have access to a 5.1.2 CLI at the moment.
I can tell you that this leads to a SegFault on 5.0.4, here is the output:
Setting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Segmentation fault
and on 5.1.1 it's not much better, the output is:
Setting insideArray

Getting insideArray

Getting insideArray
Getting insideArray

Dont know if you guys see the MAJOR difference between your code,
so I will point it out.
Jasper did this
function __get($k) {
var_dump($k);
}
Uhm, no I didn't. Jochem did :)
Jochem did this
public function __get( $key ) {
return $this->array[$key];
}
No, I did that.
First off, the required public before the function call was not
included, secondly, Jasper is var_dumping the key of the array, not
the array it self.
Public is not required. I always put it regardless, but if you leave
it off then PHP defaults to public for compatibility reasons.
Jochem's code, which behaves incorrectly, does var_dump. Mine just
returns the array key as you would expect. That's why Jochem's
doesn't behave correctly with arrays.

why is this iconv function not working for me?
i am converting $search to euc-kr charset.....
my conversion code is not working.
background and motivation
--------------------
i have to mimic a accept-charset on a form to fake a get request by
disguising it as a hyperlink. (my firefox refuses me tosend a remote
post request from a win_open() [ al a javascript] function.
the accept-charset value is 'euc-kr'.
i threw in extra iconv_set_encoding to eliminate some problem there, but
still no progress... :(
code
----------
$xab = 1;
$str_out = mb_detect_encoding($search);
$converted_search="ax";
iconv_set_encoding("output_encoding", "EUC-KR");
iconv_set_encoding("input_encoding", $str_out);
if ($xab) echo " mb_detect_encoding***" . $str_out ."***search***
$search***<br>";
if ( function_exists('iconv') ) {
if ($str_out != 'euc-kr') {
if ($xab) var_dump( iconv_get_encoding('all'));
if ($xab) echo "iconv: \$converted_search***$converted_search***
<br>";
$converted_search = iconv($str_out,"EUC-KR",$search);
if ($xab) echo "iconv: \$converted_search***$converted_search***
<br>";
}
}
output (checks that search is proper and outputs "iconv_detect_encoding"
and checks return from iconv function call)
-----
mb_detect_encoding***UTF-8***search***꺼다***
array(3) { ["input_encoding"]=> string(5) "UTF-8" ["output_encoding"]=>
string(6) "EUC-KR" ["internal_encoding"]=> string(10) "ISO-8859-1" }
iconv: $converted_search***ax***
iconv: $converted_search******
many blessings to all.
merry chirstmas.

this works for some utf8 words coming in.
strange, also, if i var_dump($converted_search) it says
----> string(4) ""
but it is completely empty for all other purposes.
by the way, is this the correct way to send an encoded value over the
internet for a href tag, as a get request?
the $converted_search is what is output from the iconv functions....
<center><h3>search from <a
href='http://nlpweb.kaist.ac.kr/Urimal/find_word.php?kt_word=\";<?php
echo
$converted_search;
?>\"&cs=ksc'>http://nlpweb.kaist.ac.kr/Urimal/</a></h3></center>

Hi there,
I am trying to encode output with php with uft8_encode(); and then output it to
an xml file. Unfortunatelly this does not work as the string that has been
encoded by utf8_encode is not valid utf8?!
Any ideas how this has happened?
Here is a link to this file:

Thank you for any hint,

Hi,
Anyone can suggest me which PHP AJAX framework you are using, for what
reason(s), what are pros and cons of your particular choice.
I found many, and now facing difficult choice.
BTW, how do you pass session id between calls to PHP from JavaScript (cookies
or explicit foo.php?PHPSESSSIONID=blahblahblah)?
Thanks in advance for any suggestion(s).

The setup is simple, usage is very easy to debug and it is actively
maintained by one of the more respected PHP coders, Josh Eichorn.
Cookies are fully supported and are preferrable to using a GET variable.

Reading Ted's post didn't give this impression. I wanted to make sure
he wasn't doing it that way.
Chris et al:
Actually I am. When I need something from the dB, I open it, get the
information and close it. It's like opening a drawer, getting what
you need, and then closing the drawer. Where's the problem?
I don't see any reason whatsoever for me to open the dB at the start
of my session and then close it at the end. Is there some
overwhelming reason for anyone to do so?
You see, my habit stems from doing a lot of communication programming
-- it was my experience that you open a communication port
(file/channel/port/whatever); establish a link; exchange data; and
close it. There's no need to leave it open.
Additionally, isn't that they way the net is set up? When your
browser accesses a web site, the browser sends a request for
information, the web site responds, and then both of you attend to
your own business. There is no maintaining an open communication
link, other than a session or cookie.
Plus, if you are talking to several devices (including dB's) at once,
then how do you know for sure which device you're talking to IF you
leave all communication ports open?
Furthermore, from a code perspective, I always comment my open and
close dB-includes as a pair -- like braces in a function or in an "if
statement". That way, I always know where in my code are the dB
segments. Additionally, I also number the error statements in the die
portion -- so if something goes wrong, I know exactly where it went
wrong.
This does not mean that I place an open/extract-insert/close dB
within a loop. If I need to get something that way, then I open the
dB before the loop and close the dB after the loop. However, I much
prefer having MySQL do the looping for me.
It's my understanding that opening a dB isn't problematic and isn't
something that I should worry about, right? It's also my
understanding that opening a dB is very fast, and it can manage a
large number of commands, and different connections very quickly,
right? Then what's the problem with opening it several times during
a session instead just once?
If someone cares to enlighten me with a convincing argument to do
otherwise, I'll certainly consider and adapt. But my guess is, that
opening a dB the way I do it presents no significant downside.
I've never had a problem with showing my ignorance before, so prove
me wrong if you can. I can learn.
Thanks.
