Re: [PHP] Array_keys problem

Good afternoon.
I'm building a class and am having a bunch of trouble with the PHP
array_keys function. I keep getting these errors:
Warning: First argument to array_keys() should be an array in D:\Htf.php on
line 33
Warning: Wrong datatype for second argument in call to in_array in
D:\Htf.php on line 35
$this-ma_arguments IS an array, so why is the error popping up? I did check
syntax but am buffaloe'd by this one.
Just so no one gets confused, I use a form of Hungarian (p=parameter,
m=module, a=array, s=string)
Since PHP doesn't have strict typing, you can't be sure what it is.
I've edited your code a bit.
/**
* @var assoc array of passed arguments
*/
//var $ma_arguments;
var $ma_arguments = array();
/**
* Constructor
*/
function bmc_html_tag_functions()
{
//$this-init();
}
function init()
{
$this-ma_arguments = array();
}
/**
* Checks if the given key or index exists in the array (PHP 4.1.0)
*
* @param $ps_keyKey to check against
* @param $pa_search Array of elements
* @return true if key is in array
* @access private
*/
function key_exists($ps_key)
{
if (!is_array($this-ma_arguments))
{
echo '$this-ma_arguments is not an array';
echo 'pre'; var_dump($this-ma_arguments); echo '/pre';
if ( in_array($ps_key, array_keys($this-ma_arguments)) ) {
return true;
} else {
return false;
}
}
Try that.

When using a link like xxx.proceed.php?language=gbr
the 'proceed.php' script does not receive any $language variable.
Does someone know how to get it run?
This is a register_globals issue. Refer to $_GET['language'] instead of
just language. Or, at the top of your script, add
$language = $_GET['language'];
and you shouldn't have to change anything else.
See the manual for $_GET and $_POST for more information.

I have to send data to flash. Should i use the urlencode() or the
rawurlencode() function to encode the data?
If you are going to be doing this a lot, you should take a look at
AMFPHP, Flash Remoting for PHP, at
http://sourceforge.net/projects/amfphp/
This seems to be a fast, reliable way to send data back and forth between
your server and your Flash client.
I have heard rumors that remoting is supposed to be deprecated in the
next revision of flash, but I'm not sure how reliable those reports are.
Remoting with AMFPHP is speedy and easy, but you may be a little better
off using XML - it's definitely chatty, but the API is stable on both
sides, and there's no reverse-engineering voodoo associated with it.

I am building a system which allows users to post data. I want to allow
them to use ONLY certain tags such as p, /p, b, /b, i, /i,
etc... I want to allow them to use only these, and then strip out ALL
attributes inside the tags. So if they input something like p junk=junk,
it would switch it to just p. Anyone know of a way this can be done?

regular expressions, heres an example:
?php
$input = 'this divis some/div ub class=haxorbad/b/u HTML';
echo {$input}\n;
$input = preg_replace('/\/?[^pbiu\/][^]*/', '', $input);
echo {$input}\n;
$input = preg_replace('/([pbiu])[^]*/', '\1', $input);
echo {$input}\n;
$input = str_replace('bad', 'good', $input);
echo {$input}\n;
?
you might also think about stripping script tags etc.
try taking a look at some forum code (e.g. phpbb.com) to see how they do
it.
no doubt that some real regexp wizard could perform the above
replacements in a single regexp but hopefully it gives you an idea... if
your not yet familiar with regexps then I strongly recommend you read
the relevant part of the manual - they are very handy things indeed.

[PHP] Intermittent problem with Session Variable and IE6
I have a php app that is in the final stages of testing and has been tested by over 30 separate users. One of the testers is having an intermittent problem which seems to be caused by a session variable not being read properly in about 1 in 3 requests - the variable is getting set correctly in the session temp file. This bug only occurs when using IE6 (XP SP2) on this particular machine, it does not occur when using Netscape7.1 on the same machine. It occurs when testing against the main server Linux/Apache 1.3.29/PHP4.2.3 and against my dev machine Win2k/Apache 2/PHP4.3.4 None of the other testers seemed to experience the same problem.

[PHP] session_exist() ?? Can this be done?
Hi, is there any way to know if a site visitor has an existing session
without having to first start the session using session_start()?
I'm trying to avoid starting a valid session unless the visitor has been
authenticated and logged in, so, here's what I do now at the top of every
page:
session_start()
if (!$_SESSION['loggedin']) {
session_destroy();
header(Location:/login.php); // Send to Log-In page.
}
Is this the most efficient way to do this? I'd prefer to not have to start
then immediately destroy the session if it's possible to first know whether
a session exists without starting it.
I have my site set to store the PHPSESSID in a cookie only (not passed via
URL), so, would checking for the existence of $_COOKIE['PHPSESSID'] be a
reliable way of doing this?
Any other suggestions are appreciated!

Re: [PHP] Session hell: register_globals off
Solved my main problem. I was assuming that variables registered with $_SESSION were passed by reference. Apparently they're passed by value. I moved the line '$_SESSION['order'] = $order;' from the top of the page 1 php code (before any properties for the order object are set), to the end of the php code -- now everything's getting passed to page 2 ok. This is an important point that should probably be in the docs section on sessions. When I coded using session_register() with register_globals on registering the variable before making changes to it worked. The '[error] PHP Notice: Undefined variable: _SESSION' happened, I think, because there were no session variables to pass so PHP killed the session. Had a previous thread on this issue. Started working on it again and am running into new bugs, so thought I'd start a new thread. Read thoroughly through session examples in docs and here's how I tried to pass an object from one page to another: page 1 __ // include class definition file include_once order_classes.php; // start session session_start(); // create instance of class Order $order = New Order(); // assign class instance to $SESSION[] $_SESSION['order'] = $order; page 2 __ // include class definition file include_once order_classes.php; // start session session_start(); // assign $_SESSION['order'] object to variable $order = $_SESSION['order']; I'm getting the following error when page 2 loads: [error] PHP Notice: Undefined variable: _SESSION Any ideas?

[PHP] Regular Expressions
I have a page where I am stripping the html tags down. Basically, it will allow certain tags, but still strips out ALL attributs of the tag, so it works something like this: $allowed_tags = pbrstrongbiu; // State which tags are allowed $info = strip_tags($info, $allowed_tags); // Strip all unwanted tags out $allowed_tags = p|br|strong|b|i|u; // Convert tags for regular expression $info = preg_replace(/(?!.$allowed_tags.)[^]*/, '\1', $info);// Strip out all attributes from allowed tags This will strip all attributes out of those tags, so it will turn something like this p some stuff hereMy p tag/p into this pMy p tag/p. The above regular expression will handle this just fine. The only problem I am running into is when someone uses a less than sign in their input (). So when someone puts something like: 2 8 in their input it gets changed to this: 2 . How can I set it to only replace things when there is a and a matching for it? Anyone have any ideas?

[PHP] Using PDFLib
Hello, I am trying to generate PDFs using PDFLib for the first time, and have two questions, one of which is very confusing to me. 1) how can I tell the script generating the pdf to store it in a particular place on the computer where the pdf generation is happening? 2) this is the really confusing one. The text being put into the body of the pdf is an article about 6300 characters. The tutorials I have found all follow the same format, and end up printing all of this text in one line (or row), so that the pdf ends up being just one line across. So the question is, how do I get the text to be placed normally on the page, so as to be a readable document? I should add that I am using a block of text sent from an HTML form. Here is the PHP script: ?php $author=$_POST['author']; $text=$_POST['text']; $pdf = PDF_new(); PDF_open_file($pdf); PDF_set_info($pdf, author, $author); PDF_begin_page($pdf,612,792); $font = PDF_findfont($pdf, Helvetica, winansi,0); PDF_setfont($pdf,$font,12); PDF_show_xy($pdf, $text, 5,225); PDF_end_page($pdf); PDF_close($pdf); $buffer = PDF_get_buffer($pdf); header(Content-type: application/pdf); header(Content-Length: .strlen($buffer)); header(Content-Disposition: inline; filename=sample.pdf); echo $buffer ?

On 4 Apr 2004 Randall Perry wrote: Solved my main problem. I was assuming that variables registered with $_SESSION were passed by reference. Apparently they're passed by value. *Passing* by value or by reference has to do with function parameters, not array values. However you can assign one variable as a reference to another, see http://www.php.net/manual/en/language.references.php. When you enter a line of code like: $_SESSION['order'] = $order; you are doing a regular assignment. To use a reference instead, use: $_SESSION['order'] = $order; The data will be passed this way to the next session. For example, try this (substitute your server name in the header() call): test1.php: ?php session_start(); $test1 = ; $_SESSION[Test1] = $test1; $test1 = this is test1; header(Location: http://localhost/olm/test2.php;); ? test2.php: ?php session_start(); var_dump($_SESSION); ? The output on the second page will be something like this (I'm using xdebug so this is not raw var_dump() output): array 'Test1' = 'this is test1' -- Tom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

how would you empty all the contents of $HTTP_SESSION_VARS when you dont need them anymore but still keep the current session running? the problem seems to be that when i try to fill them with something else (dont need the original values anymore) but need new ones without destroying the session itself they wont fill with new things. unset($HTTP_SESSION_VARS); does nothing to help at all because they still have the same values that they were originally filled with (and not to mention they are still in the session)... anybody have any ideas how to delete or empty out the array but keep the session active ??

Something else in your code is messing you up if you cannot change the value after setting it in the first place. This happens all the time in my code as my client makes decisions along the way. Try a small test creating a session variable, displaying it, changing it, and redisplaying it. If it does not show the change, post the test code so we might be able to tell why it fails. Provided you can change the variable, you should be able to create a loop that sets all the variables to or some base values etc. Larry -Original Message- From: Andy B [mailto:[EMAIL PROTECTED] Sent: Sunday, April 04, 2004 6:03 PM To: [EMAIL PROTECTED] Subject: [PHP] $HTTP_SESSION_VARS still holds original values even after unset? how would you empty all the contents of $HTTP_SESSION_VARS when you dont need them anymore but still keep the current session running? the problem seems to be that when i try to fill them with something else (dont need the original values anymore) but need new ones without destroying the session itself they wont fill with new things. unset($HTTP_SESSION_VARS); does nothing to help at all because they still have the same values that they were originally filled with (and not to mention they are still in the session)... anybody have any ideas how to delete or empty out the array but keep the session active ?? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi there, Supposed I have an array of objects, like: $this[$i]-property1 $this[$i]-property2 is there any 'cheap' way to sort the array according to the values of property1? The only way I thought I would be able to accomplish this is to transform this into an assoc array or something like it and then sort it ... I found plenty of functions for dealing with plain arrays, but nothing - easy to use - for this. Am I just blind or do I finally have to write a function doing that on my own? And if so - anyone who had to do this before and come up with a really fast solution (I guess my attempts would work - but not very efficient) Thanks Richard -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: $HTTP_SESSION_VARS still holds original values even after unset?
Okay, start showing some code so we can see wtf is going on. Constantly posting back nope, doesn't work is just going to have us grasping at straws again and again. Is register globals on or off? register_globals=off here is the code that gives me problems: files are attached (if allowed) let me know if the attached files didnt make it through and i will post it in the body of the message...the code is quite huge chunck of stuff... file guestbook_add.php: is a form used for admins to insert a guestbook entry. it is linked from a admin page using session_start(); at the top of the admin main page. the button that links to this page code is: input class=button type=button value=add guestbook listing accesskey=3 onclick=window.location='guestbook_add.php'; onkeypress=window.location='guestbook_add.php'; after filling out the form and submitting it to the file called guestbook_review2.php it sets all of the $HTTP_SESSION_VARS[] vars to the inital form submitted values and shows them on the page. after they hit the continue button it checks for default/required vars and then inserts to the db in the file called guestbook_save.php.. after a successful insert it takes them back to the main admin page. the next time i hit the add guestbook listing from the main screen, fill out the form with different values and submit it all the $HTTP_SESSION_VARS have the same values as the last add sequence... its interesting...(i know the code may be sloppy but...im starting out with complex stuff and was forced on a super fast turn around on it)... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

There are two problems there. First, your session data is not getting cleared. Second, it is not getting reset with the new values. For the former, in guestbook_save.php you can simply do a session_unset (if you really want to clear all of them). However this does not handle an abnormals equence -- for example someone hits Back in the middle of the process. I don't understand why they are not getting set properly the second time around. It could be a condition in your code. I'd have to see the code to have an idea. Try stripping the code WAY down so you have a test_add.php with a 1- field form, and a test_review.php that displays that data and saves it in a session variable, and test_save.php that just displays what it receives in the session variables. If that still fails, post the code. If not, your problem lies in the difference between that and the original code. -- Tom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] session_exist() ?? Can this be done?
* Thus wrote Monty ([EMAIL PROTECTED]):
session_start()
if (!$_SESSION['loggedin']) {
session_destroy();

}
Is this the most efficient way to do this? I'd prefer to not have to start
then immediately destroy the session if it's possible to first know whether
a session exists without starting it.
Yes. But you dont *need* to destroy() the session. btw, your
Location header should be like this:
Location: http://domain.com/login.php
I have my site set to store the PHPSESSID in a cookie only (not passed via
URL), so, would checking for the existence of $_COOKIE['PHPSESSID'] be a
reliable way of doing this?
A cookie can easiy be sent without ever being assigned one. Doing
this will open a large hole in your security model.

Hi, is there any way to know if a site visitor has an existing session

I'm trying to avoid starting a valid session unless the visitor has been
authenticated and logged in, so, here's what I do now at the top of every
page:
session_start()
if (!$_SESSION['loggedin']) {
session_destroy();
header(Location:/login.php); // Send to Log-In page.
}

I've been doing exactly that, it works great. I use,
$sessid = $_COOKIE[PHPSESSID];
if ( isset($sessid) ) {
session_start();
}
I use 'if( isset($sessid) )' in the rest of the code if there are things
that should only be done if there is a session. Only my login
authentication page starts the session if there isn't a cookie. Of course,
for security you ought to verify the session after starting it, and unset
$sessid (and destroy_session() ) if something screwy is going on.
The reason I set things up like this is so that users are not bothered with
cookies unless they need to be. I use cookies for the administration side
of the site, but casual users don't need a session, so why should they have
a cookie? -- I'm a not a proponent of passing around useless data :).
Any other suggestions are appreciated!

This should do what you want, though I think your example is
confusing...
?php
function cmp_ascending($k1, $k2) {
global $a;
if ($a[$k1]-property == $a[$k2]-property) {
return 0;
}
return ($a[$k1]-property $a[$k2]-property) ? -1 : 1;
}
class test{
var $property = 0;
function test($val){
$this-property = $val;
}
}
$a[] = new test(7);
$a[] = new test(1);
$a[] = new test(5);
$a[] = new test(3);
print_r($a);
uksort($a, cmp_ascending);
while (list($key, $value) = each($a)) {
echo $key: $value-property br;
}

[PHP] Weird variable issue encountered... help needed!
This problem only seems to be happening on one of the virtual hosts on this system, and I cannot seem to figure out just what it is. I have a simple form posting to search.php, with a text input field, with a name of 'search'. And since this site is an internal site, register globals are on, as we are not worried about anyone misuing any of the variables in use. In any even, this problem was noticed about a week ago, and it did not exist before. After inputting some text into the search box, in this example, 'var', sans quotes, and i hit submit... on the next page, I am just having it return just $search for testing, and, it comes back sporadically with: 'var', but most of the time, it comes back with: var^!#ndda/form or var4194092d098240928d12ed or var#c0c0c0 or varput type=text etc. etc. it seems soemthing is somehow corrupting the variables, and I cannot seem to figure out what it might be. This has been working fine until about the past week, and I cannot think of any major changes that may have happened within the past week that could have caused this... and as I mentioned above, it only seems to be this one virtual host. And ai also compared with backups of all of y included files at the beginnings and ends of each script from before this problem started happening, and I can see no major changes in any of them. And, this is happening around all php scripts on the site... I am running 4.3.4, with apache 2, FreeBSD 4.8, and the data is all stored on a vinum partition. The server has been rebooted, a fresh install of php... tried setting output buffering on and flushing it at the end of the script(s), however, they seem to get hacked up when doing that, so I stay away from that band-aid fix...I am using sessions as well, as a few scripts within the site store session variables... and also using SMBAuth to do authentication from our domain controller... I've been pulling out my hair for 4 days straight on this issue, and I am all out of ideas, any help would be *GREATLY* appreciated! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
