Re: [PHP] Subtracting Money
Hi Stephen, I'm having a problem. I need to subtract money, but if they type in an ammount such as $2.30 and I subtract $0.20, instead of returning $2.10 like it should, it returns $2.1. How can I fix this keeping in mind that other variable could be $2.40 or $100.30 and so on...? This is because, 2.1 is equal to 2.10 :-) You need to format the numbers in the way you want them. have a look at: http://www.php.net/manual/en/function.number-format.php and/or http://www.php.net/manual/en/function.sprintf.php both of them should do that job. sprintf's Example 6: $money1 = 68.75; $money2 = 54.35; $money = $money1 + $money2; // echo $money will output 123.1; $formatted = sprintf(%01.2f, $money); // echo $formatted will output 123.10 -Sascha -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] $_SESSION question
Simply put - you can't. You need a way to transmit the session identifier, and AFAIK there's nothing except either cookies or SID. Using SID for security relevant issues presents a problem - users can send links with a SID to friends by mail or else, so this is not really a secure solution. However there are numerous application parts where no security is involved, and sessions are just used to construct a site - it's unnecessary IMHO to avoid SID use here. On our server we have disabled session cookies in general, as a courtesy to our users. However when logged in we require a user to accept a cookie. The value of this cookie is randomly generated (something like md5(rand())), and changes with every click. This value (we call it a login token is also stored in session data to verify the cookie against the session. If no user token, or a wrong token, is transmitted, we assume a hijacked session and automatically logout the user. (there's more to it, but basically you get the idea) This sounds like a pretty good idea to work around that problem :-) Does this system work, if the user decides to split one session accross multiple Browser-Windows, i.e. the uses the Open in new window-Function of most browsers? -Sascha -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] $_SESSION question
Hi Jochen, How can I process $_SESSION variables if the user disables cookies and session.use_trans_sid = 0 ? You could use a combination of outputbuffering and a self-written session-handler. So you could build a trans_sid-alike system, that would do more checks (i.e. compare IP-Addresses) to validate, if a session is really the one it is claiming. (Of course this would be slower as trans_sid's and ain't that easy to do) -Sascha -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] POST-ing or GET-ing an array
Hi,
first of all, i would prefer to do this task in a session-variable (less
traffic, less security holes).
But, if you're sure you need to pass the array via an URL, try:
A HREF=test.php?ary[]=1ary[]=2
which will result in test.php called with $_GET['ary'] containing:
[0] = '1'
[1] = '2'
If the array contains strings (as databases usualy do), you should url-encode
them.
If there is a better way to do this task, please let me know too.

Re: [PHP] POST-ing or GET-ing an array
Hey,
I think you should be able to serialize and urlencode the array and then
pass that via get/post.post would be a lot better as get is limited to
so many chars. Something like:
$sql = select stuff from my_table;
$result = mysql_query($sql);
while ($myrow = mysql_fetch_assoc($result)) {
$id = $myrow[id];
$my_array[] = $id;
}
echo 'a href=next_page.php?array='. urlencode(serialize($my_array))
.'Next/a'; You'll need to unserialize+urldecode the array at the other
end.

Re: [PHP] Re: POST-ing or GET-ing an array
Hi, I disagree that serialize/unserialize is the way to go, unless you're absolutely completely sure that there will only be a relatively small number of things in the array. As somebody mentioned briefly, the get request is limited to a certain number of bytes, and the string representing your serialized array could easily get too large to send on a get request. imho the best option is to use the session, which somebody already mentioned but didn't really elaborate... $_SESSION['my_array'] = $my_array; Exactly. But just to mention it at this point: if you have script-output (echo, print, print_r etc.) before any operation on $_SESSION, you should call start_session() at the start of the script. (I don't know if recent versions of PHP still _need_ this) and on next_page (or any other page), you'd just use $_SESSION['my_array'] where you need. I would suggest, unsetting the array in the next_page (or whatever) after you don't need it anymore: unset($_SESSION['my_array']); Another option would be to send the request as a post, and serialize the array into a hidden variable in your form; that way you won't have to worry (as much) about size constraints. (a post request is also limited in size, but it's so large that you probably would never approach the limit.) /nick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Upload Problem
Hi,
as far as i can follow you, you want to:
1. copy a file from position a to position b.
2. read it from position b.
3. and delete it at position b.
Why not read it directly from position a?
So what about:
$content = implode(br, file($userfile));
Anyway: You should initialize $i in any way, best with zero - $i=0; before
the while loop.
You check if 0.tab 1.tab 2.tab; if 2.tab exists, you create 3tab (A dot seems
to be missing) $destfile .= '.tab'; instead of $destfile .= tab;

The value of name for the submit button is wrong - it should be the same
as the value you gave the isset statement, in this case it should be
input type=submit name=name value=sendit
Better yet is to use isset($submit) and the value for the submit
statement is also name=submit -
input type=submit name=submit value=sendit
of course value is optional. So you end up with this -
?
if (isset($_GET['submit']))
{
echo Hallo .$GET['name'];

echo FORM action='test.php' method=get

Re: [PHP] getimagesize or loop pblm
You can calculate the image size when adding the image (rather than when
displaying it) and store the information in a file or a database. This file
or database you could use for posting the right sizes for popup windows.

It could take a while. Depends how fast your server's disk sub-system is.
Going to disk to stat and open an image and then parse through the initial
headers to get the sizing data can take some time. I'd suggest caching
this data somewhere if you are going to need it on every request.

Re: [PHP] backwards compat for newly developed scripts ($_GET / $HTTP_GET_VARS)
Hey gang,
I've been wondering about developing scripts that the end-user might run on
php 4.1.0. I've heard allot of ways except for one that I recently
thought of.
How about using:
-
if(!isset($_GET)) { global $HTTP_GET_VARS; $_GET = $HTTP_GET_VARS; }
-
? That allows you to use $_GET as if you were using the new versions and it
only requires one lineand doesn't depend on the new versions to have
$HTTP_*_VARS. It also works for the other vars(POST, SESSION, etc).
If any script shall be executeable on such an old PHP release, this method
sounds really good. But, for security reasons i would prefer to ship this in
an extra script, which the user has explicitly to include (Maybe just
paranoia)...
Hmm, anyway it would be better to force those old versions to be updated -
since 1) there was a lot of security changes/updates and other bug fixes 2)
new functions have been developed in more recent versions. i.e. executing
stored procedures on MSSQL. I think, this will force people much more to
update. Wouldn't it be better to force them now, than provide backward
compatibility for _new_ scripts?

Re: [PHP] backwards compat for newly developed scripts ($_GET / $HTTP_GET_VARS)
ummyou'd have to include that line at the top of every function that uses get(or any of the other) vars(scoping reasons) or somehow pass it via a reference to the function. I've always added the line at the top. At the top of each _function_? Urgs. Sounds like a hell of a lot of work. Would be enough at the beginning of the script - or even better, creating a dummy include for that or it might even be posibile to run it via an .htaccess (how is this option named php_prepend or such?). ... Thats if the user has the option to upgrade - some system admin don't like to do their job...I know of quite a few isps still running 4.0.6:( If they can't update the PHP Version they should update the ISP :-) Well, 4.0.6 might be a famous release (as you can find this very often), but it's about 1 year old now... If ISPs don't updated, they make their own machines vulnerable - the only conclusion (to make them learn their lesson) can be, that customers keep on running away, ain't it?

Re: [PHP] Undefined constant error
make sure you have register_globals on in php.ini or your next question
will be 'why isn't $compteur set to the value posted?' Better would be to
change the line to the new magic globals, and learn the right way from
scratch:
I agree with you as far, as to learn the right way from scratch - but this is
no POST-Var here.
echo input type='radio' name='interet' value='$animalType';
if ($_POST['compteur'] == 1) {
echo checked;
}
echo ;
This is another bug in the script. Considering that, it would be correctly:
(Note the space between '' and 'checked')
echo input type='radio' name='interet' value='$animalType';
if ($compteur == 1) {
echo checked;
}
echo ;
or shorter:
echo
input type='radio' name='interet' value='$animalType'.
($compteur == 1 ? ' checked' : '') . ;

Re: [PHP] Htmlentities and Newlines?
Hi John, Sorry about the ambiguity. What I'm trying to accomplish is close to what you describe. However, before anything goes into the db (ie html chars, bad commands, or anything from Mr.Hacker), I verify it. Someone suggested, way back when I first started with textarea, to use 'htmlentities' to strip the bad items out. You should always save it in the database exactly how the user typed it. So far, so good. But, if I follow what you suggest (and it's eminently reasonable!) I could have some 'bad stuff' becoming 'resident' in my db. Perhaps I am paranoid, but that seems like a-bad-thing-to-do. Save it with newlines and don't add any HTML code to it. Ahh . . . if I save as the user typed it, assuming Mr. Hacker has added some little extras, what then?? I use a Preview mode for viewing what thgey've entered, and they must go back to the textarea box if they need to edit (which has exactly what they typed.) Oh, this all did sense to me a while ago, but I am tired, and it's beginning to sound like gibberish . Thanks again. Andre Things will be alright, if you follow two rules: 1. before Output, use htmlentities() to make sure, your text isn't confused with HTML (This way noone can insert HTML-Tags into your Text). 2. before saving to database, either use addslashes() or turn on magic_qoutes in php.ini. (This will ensure, that noone drops your database on the fly. e.g. Enters something like '; drop database;' into a textarea.) as i remember magic_qoutes should be turned on by default. Don't do anything else with data that goes to your database, or you'll lose posibility to edit it later on.

Re: [PHP] Htmlentities and Newlines?
Yeah, good catch on the addslash/magic_quote. Also, FYI: PHP will only allow you to do one query per mysql_query(). So you can't try to end a quote and then send another query.

Does PHP do what? By default the MySQL query function can only take one query at a time. There is nothing strange about this. The command-line mysql tool can take multiple queries separated by semi-colons, but that is something that is implemented in that command-line tool.

Re: [PHP] Running a PHP script automatically?
On the Linux box compile PHP as CGI (i.e. don't configure it as an apache mod). Then you can just run your script from the the command-line. This is called CLI (Command Line Interface), not CGI (Common Gateway Interface). The CGI is called from an WebServer; CLI get's called from a shell-(script) or any thing. Anyway, this is the most likely way to do this. The PHP Binaries for Windows already ship with a CLI-Version of PHP which lives in the root of your PHP folder. Most Linux Distribution have also one (I'm not using Red Hat), which would usually live in /usr/bin/php ( to find out, type: whereis php).

There are many different states, in which an array would be empty. Can you post the output of a var_dump($array); in that special case you want to check? In general: 1. the variable may not have been set: if (!isset($myarray)) echo 'error'; 2. the variable is set, but ain't an array: if (!isarray($myarray) echo 'error'; 3. the variable is set and is an array, but contains no data: if (array_count($myarray) == 0) echo 'error'; I think the 3rd case could apply to your problem, but only a print_r or var_dump of the $_POST['myarray'] can show this.

Re: [PHP] Friend of function??
Just as Kevin Stone said, you can either use one of these constructions:
function func1() {
global $myarray;
array_push($myarray,1);
}
# _or_
function func2() {
array_push($GLOBALS['myarray'],1);
}
In fact, there is no performance decrease, because PHP will internally use the
same mechanism to access the array - as it would if you were not in a
function.
Another way would be to pass the array as a reference:
function func3($myarray) {
array_push($myarray, 1);
}
but this might decrease performace (in compare to the other ways, you will not
really notice it).
