First of all .. always be careful with tainted data.
Like when you

be aware that this could be a security risk one day an ImageMagick
exploid is circulating.
At the first glance I saw a syntactical thingy that might cause problems ..
case default:
break;
In PHP switch for default this way ...
switch ($statement) {
case 1:
// do something
break;
default:
//do something else
}
then you forgot a semicolon
$orientation = $image->getImageProperty("exif:Orientation"); // <--- ; added
after that I got your script running.
Note:
At least turn error reporting on during debugging etc.
All error-reporting behavior can be modified at any level, so if you
are on a shared host or otherwise unable to make changes to files such
as php.ini, httpd.conf, or .htaccess, simply ...
ini_set('error_reporting', E_ALL | E_STRICT);
ini_set('display_errors', 'OFF');

Well, since Javascript does the Job anyways you don't have to load it
with the page when doing the div method.
You would only need this little addition to your css ..
.div_win {
position: absolute;
width: 400px;
top: 100px;
left: 10%;
visibility: hidden;
}
When user initializes the request by clicking a link
var div_window = document.createElement('div');
div_window.setAttribute('class', 'div_win');
div_window.className = 'div_win';
document.body.appendChild(div_window);
Then you do some AJAX or JSON or whatever and apply it to the div.
You can also move the div around doing it somehow like this ...
http://www.quirksmode.org/js/dragdrop.html
Still, opening up a new window might be the simple solution after all lol.

In that case I would go for an algorithm using some kind of gaussian
distribution, like the Marsaglia polar method [1].
I once wrote something similar to what (I think) you are asking for ...
1) {
$u1 = 1/(rand(1, $likelihood)*$likelihood);
$u2 = 1/(rand(1, $likelihood)*$likelihood);
$v = $u1*$u1 + $u2*$u2;
}
$p = $u1*sqrt((-2)*(log($v)/$v));
return ($p < 0.85) ? 1 : (int)$p;
}
?>
The best return of this function would be 1. Now if you call the
function with a high $likelihood (say 1000 and more) it gets less
likely have 1 returned ( gaussian ).
If you want to decrease the chance of getting values close to 1 then
you will have to increase $likelihood inside the function or
something.

Re: [PHP] Voting methodology
I once had to implement something similar for a client's intranet page. First we designed it to work without login simply by logging the IPs (static and in the 10.10.*.* range) to avoid people voting twice or more. Then the client wanted to have some statistics like what department voted for what (yeah, not very democratic i know). So we changed it have the user log in before voting. Now we could also make sure that only authorized users were voting, unless a user forgot to log out and a delivery guy was taking his chances (very unlikely). I think the thingy about online voting is to ask oneself how serious the result has to be. Getting a 99% bulletproof result might be quite time consuming (thinking of HTTPS, tokens, authorization, etc. here). So it all depends on what your client wants. //A yeti -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Short circuit evaluation and include
Hello everyone,
I'm posting this as a warning when using include() or include_once()
and checking their return values.
I'm refactoring someone else's code at the moment and got a short
circuit evaluation problem that made some problems ..
Here's the code:
FILE "some_file.php":
some_method()
) return false; // line 14
return $obj;
}
$file = 'some_class.php';
some_function($file);
?>
FILE "some_class.php":
ERRORS PRODUCED:
Warning: some_function(1) [function.some-function]: failed to open
stream: No such file or directory in */some_file.php on line 14
Warning: some_function() [function.include]: Failed opening '1' for
inclusion (include_path='.;*/php/pear/') in */some_file.php on line 14
Note: I ran this code in PHP 4.4.9
It seemed to me like include_once() was not fully executed or
something when "short circuited", because this code worked just fine
...
FILE "some_file.php":
some_method()
) return false;
return $obj;
}
$file = 'some_class.php';
var_dump(some_function($file));
?>
OUTPUT:
object(some_class)(0) {
}
So I was wondering how include() or include_once() are actually being
executed. I know they both return int(1) if no return specified in the
included file.
That's why I had a glance at the manual [1], where I saw this ..
Because include() is a special language construct, parentheses are not
needed around its argument. Take care when comparing return value.
Example #4 Comparing return value of include
So when I added the paranthesis it worked ...
FILE "some_file.php":
some_method()
) return false;
return $obj;
}
$file = 'some_class.php';
var_dump(some_function($file));
?>
Me, after an hour of coding without a line of code.

The only solution I could think of was to have the server admin set an environment variable in an httpd.conf include file owned by root (chmod 600) [1]. EXAMPLE (mysql_pw.conf): SetEnv mysql_pw password SetEnv mysql_user username In PHP the variables then should end up in the $_SERVER array ... EXAMPLE (PHP): If this is impossible I can't think of another secure way on shared host systems, since other hosts usually are able to read your files. Maybe (if supported) one could SetEnv in .htaccess, so an attacker would at least have to glance into the PHP source code to find out where the password is stored. Still most people have it inside an include file and it works, I think.

Since you are looping through the result already, why not do it this way ..
$combinedArray = array();
for ($i=0;$i 0) {
while ($myrow = mysql_fetch_array($result)) {
if (in_array($myrow['study'], $myArray))
$combinedArray[$myrow['study']][] = $myrow['symbol'];
}
}
}
You should get an array like this ...

[PHP] Help on caching an object.
Hello gang, First of all, yes I searched the mailing list's archive. My problem is very simple: I have an object that's definately called with every page request. It's pretty much the same for every unregistered/anonymous user. And it's not small. Alot of attributes are being set from DB queries etc. Now my idea was to do some sort of caching with PHP to speed things up. So I was wondering if anybody had experiences on this ... Of course, I considered using serialize(), but it seemed to me as if it could cause even more lagging since PHP requires the class to unserialize the object correctly. Then I would end up reading the class file, reading the searialized object and unserializing it. A 100 simple DB queries might be done in the same time or at least not much slower. Could it be that I'm looking at the wrong place? Should it be more like caching the queries or something similar?

[PHP] IPv6 validation
Hello community,
I have been working with alot of IPv6 lately.
Now i was wondering of what there might be the best way to validate an IPv6
address.
Couldn't think of any working regexp, since even ::1 or :: is valid
(localhost), so i tried it the following way:
http://tools.ietf.org/html/rfc4291
function validate_ipv6($value) {
if (substr_count($value, ":") < 2) return false; // has to contain ":" at
least twice like in ::1 or 1234::abcd
if (substr_count($value, "::") > 1) return false; // only 1 double colon
allowed
$groups = explode(':', $value);
$num_groups = count($groups);
if (($num_groups > 8) || ($num_groups < 3)) return false; // 3-8 groups of
0-4 digits (1 group has to be at leas 1 digit)
$empty_groups = 0;
foreach ($groups as $group) {
$group = trim($group);
if (!empty($group) && !(is_numeric($group) && ($group == 0))) {
if (!preg_match('#([a-fA-F0-9]{0,4})#', $group)) return false;
} else ++$empty_groups;
}
return ($empty_groups < $num_groups) ? true : false; // the unspecified
address :: is not valid in this case
}
var_dump(validate_ipv6("::")); // false (wanted result)
var_dump(validate_ipv6("::1")); // true
var_dump(validate_ipv6("1234::abcd")); // true
var_dump(validate_ipv6("2001:DB8:0:0:8:800:200C:417A")); // true
var_dump(validate_ipv6("0:0:0:0:0:0:0:1")); // true
var_dump(validate_ipv6("0:0:0:0:0:0:0:0")); // false (wanted result)
var_dump(validate_ipv6(":::::::")); // false
(wanted result)
var_dump(validate_ipv6("2001:0DB8::CD30::::")); // true
var_dump(validate_ipv6("FF01:0:0:0:0:0:0:101")); // true
var_dump(validate_ipv6("bananas")); // false
var_dump(validate_ipv6("1:2:3:4:5:6:7:8:9")); // false
?>
anybody with better ideas?

Re: [PHP] IPv6 validation
It will still take some time until every provider has PHP5 running, at least
where I am from. I have many customers who want me to get their sites
running on some cheap webspace they got along with their internet
connection. Then you have to tell them it won't work because of some problem
with the versions. I would love to write code for PHP5+ only.

Re: [PHP] case and accent - insensitive regular expression?
The original problem was User X submits a character string A. A PHP scripts uses A to search for it's occurences in a DB, ignoring special characters. The result of ze search is a list of character strings M-LIST with matches. This list gets outputted to the user X, but before that all the matching strings should be replaced with ''..'' If i clearly got the OP then he is using MySQL to perform the search. I guess he is doing it with MATCH. So MySQL already found the match and in PHP it has to be done again ... eg. The table has 2 entries, string1 and string2 .. string1 = 'Thís ís an éxámplè stríng wíth áccénts.' string2 = 'This is an example string without accents.' Now the user searches for "ample": search = '*ample*' Both string have matches due to accent-insensitivity (AI). Now the result is outputted with highlighting .. *Thís ís an éx**ámplè** stríng wíth áccénts.* *This is an ex**ample** string without accents.* So since MySQL already did the job, why not get the occurances from it? I'm not an MySQL expert, but I know google and found something called string functions. Especially a "locate" function got my interest. http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_locate Now shouldnt it be possible to create a query that searches the db for matches and additionally uses the string function? I have no idea, but maybe some MySQL-expert out there has ...

Re: [PHP] After INSERT form submit - Data doesn't refresh!
ok, in that case forget the Last-Modified or set it to the current date.
header('Last-Modified: '.gmdate('D, d M Y H:i:s', time()).' GMT');
Did you turn caching off in your browser and try it then?
Or try it with a different browser?

[PHP] Reference or copy?
Hello everyone,
Many of you may be familiar with references in PHP. Now i read
somewhere in the PHP manual that creating references can take longer
than copies. PHP5+ also seems to reference a bit different thant PHP4
did.
Here is some working example code:
huge_array = array();
for ($i = 0; $i < 1024; $i++) $this->huge_array[] = $GLOBALS; //
fill ze array with copies of $GLOBALS array
return true;
}
function useless() {
return $this->__construct();
}
}
$time_start = microtime(true);
$test_obj = new useless();
$time_end = microtime(true);
$time = $time_end - $time_start;
echo "It took {$time} seconds without using the reference operator.\r\n";
unset($test_obj);
$time_start = microtime(true);
$test_obj =& new useless();
$time_end = microtime(true);
$time = $time_end - $time_start;
echo "It took {$time} seconds using the reference
operator.\r\n## with obj2 \r\n";
$time_start = microtime(true);
$test_obj = new useless();
$obj2 = $test_obj;
$time_end = microtime(true);
$time = $time_end - $time_start;
echo "It took {$time} seconds without using the reference operator.\r\n";
unset($test_obj);
$time_start = microtime(true);
$test_obj =& new useless();
$obj2 =& $test_obj;
$time_end = microtime(true);
$time = $time_end - $time_start;
echo "It took {$time} seconds using the reference operator.\r\n";
?>
I tested the code in PHP 4.4.7 and in PHP 5.2.5 and the results were
pretty much the same. Using references speeds up the script!
Occasionally obj2-with-references took longer than all the others. But
i don't know if that's to be taken serious.
Now if i do not need a copy, isn't it smarter to use references instead?
I'm grateful for any ideas, thoughts or experiences
Yeti

Re: [PHP] Writing my own web based user forum
If I fully understood the question you were asking then no.
Since it seems you are using a database there is no need to serialize.
You can write a simple function that fetches user data from a DB query
and then creates the object.
If you are going to use sessions you will have to do that only when
the user logs in and for verification purposes of whatever kind.
You might think of something similar to:
http://webbytedd.com/b1/simple-session/
In your original post you did not mention a "picture upload site" so I
suggest it is about uploading pictures to the forum/attaching them to
a thread.
I do not really have an idea of how your site will be operating, but I
guess you analyze the GET parameters and include files according to
them.
Some code might be helpful to explain what you want

Re: [PHP] Internationalisation and MB strings
Oh right. Doing 1 measurement only is not even worth a theory.
Well, I'm wondering how much PHP can speed that result up, since we are
calling the same function with the same parameter 1 times. Wouldn't it
be even more realistic if we called it with changing strings?
MB_STRLEN took : '.(($e_t - $s_t)*1000/$iterations).'
milliseconds';
$s_t = microtime(true);
foreach ($mb_array as $mb_string) {
strlen('œŸŒ‡Ņ');
}
$e_t = microtime(true);
echo 'STRLEN took : '.(($e_t - $s_t)*1000/$iterations).'
milliseconds';
?>
MB_STRLEN took : 0.0525826 milliseconds
STRLEN took : 0.0020655 milliseconds
I could not find out how well str_shuffle supports multi byte strings in
PHP4, so I'm wondering if I did this right ..

That is why i love this list. Always something new to learn.
What I am still wondering about is if it is faster to use commas or

I'm not a walking dictionary)

Re: [PHP] Alternative to HTTP_REFERER?
By definition: The referer, or HTTP referer, identifies, from the
point of view of an internet webpage or resource, the address of the
webpage (commonly the URL, the more generic URI or the i18n updated
IRI) of the resource which links to it.
More detail at:
http://en.wikipedia.org/wiki/Referer
http://tools.ietf.org/html/rfc2616
So is a redirecting page a referrer or not? I don't know. Had no time
to translate the gibberish.
I experimented a bit with it and the most suitable solution I found
was passing the referring page on with a GET parameter ...
## A page redirecting to test.php ##
## test.php ##

http://www.w3.org/1999/xhtml";>

You are absoloodle right about that. Although I'm not sure about their

I prefer the '{0,}' in my rewrite rules because I usually define the

Re: [PHP] Pure PHP Templating Class/AJAX Problem
Well after looking at the template thing you posted with your link it
seems to me like PHP is used to create working XML. So i wonder why
you are using AJAX here.
Now could it be that you use appendChild() ? That function would
simply add the XML again.
It's not easy to tell if you are not showing the JavaScript code ..
Still it simply depends on how you are importing the node you get from
XMLHttpRequest() or responseXML
Btw. importNode() is not working on all Browsers ..
Below is a code snipped I use for my AJAX class in JavaScript to copy
a node of one XML document (like from responseXML) into another. It
works in IE6+ and all W3C compliant browsers.
To make this work you will still have to make some ajustments.
xml_obj.prototype.xml_import_node = function(node, to_node,
all_children) { // cross browser importNode, NOTE: if toNode not
specified it will be set to current root_element
// appends node as a child to to_node
// if all_children is true then all child nodes will be imported too
/* NOTE TYPES:
ELEMENT_NODE = 1;
ATTRIBUTE_NODE = 2;
TEXT_NODE = 3;
CDATA_SECTION_NODE = 4;
ENTITY_REFERENCE_NODE = 5;

Secondly the MIME type can differ from the extension (file suffix)
It's the same with uploaded files. Although the browser sends the MIME
type it might not be the right one, since browsers obtain the MIME by
checking the extension.

Re: [PHP] Inheritance of class methods
Using extends means that a class IS-A substructure of its parent class(es).
EXAMPLE:
class plant { };
class tree extends plant { };
class apple_tree extends tree { };
apple_tree inherits all methods and attributes from plant and tree
So if there was a methods plant->growth() you can also call it from
tree and apple_tree
IS-A versus HAS-A
apple_tree IS-A tree
apple_tree HAS-A fruit called apple
So apple does not extend apple_tree because it is not a tree
EXAMPLE:
class apple {
var color = 'blue';
var inhabitant = 'worm';
}
class apple_tree extends tree {
var apples = array(new apple());
