Re: [PHP] mail headers mail filtering
Hi Tom I did finally get my mails on this account (my personal mailbox) hours later but my main problem is with mails sent by scripts on my site (using the mailserver of my web provider) and other people complaining to me that they dont get mails sent from their websites to their ISP mailboxes (using my scripts). More and more legitimate mails are being trashed as a result of anti-spamming systems - read around the IT news. Whether it is illegal or not I don't know but yesterday I cancelled my account with my ISP because they refuse to answer my questions re if they have a mail filtering policy and if they do what is it.

I'm having another problem with my member's area script. When someone
logs in, it's supposed to register their username into a session and it
displays fine on the first page. But once you navigate to another part
of the area, it does not tell you you are logged in, instead it gives me
the error I set it to give You are not logged in. Here's the code
that checks to see if the user is valid:

Re: [PHP] calling session_start()
session_start() has to be called on every page where you want to use the session, before you try referencing it - you also have to call it before outputting anything else (you must be doing it after and this is what is causing your error) - Original Message - From: Børge Strand [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, September 29, 2002 6:12 PM Subject: [PHP] calling session_start() Hi All, When does session_start() have to be called?

Every page in the frameset says Warning: Cannot send session cache limiter - heaaders already sent... in response to session_start() in the test I described above.

Re: [PHP] Not Displaying From Vars??
Its a setting in php.ini where PHP creates vars from form data/cookies if its on. If it is on - its a security risk because anyone can change the value of the data in your script by passing values in thru the URL. So you need to keep it switched off (whereby vars will not be created from form data) and use the superglobals $_POST, $_GET, etc to access your data instead. - Original Message - From: Stephen Craton [EMAIL PROTECTED] To: 'debbie_dyer' [EMAIL PROTECTED] Sent: Sunday, September 29, 2002 7:29 PM Subject: RE: [PHP] Not Displaying From Vars??

Re: [PHP] Not Displaying From Vars??

Yes you are right in what you say but:-
I would argue that register_globals only presents a security risk to
inexperienced developers.
And how many of these are putting code on the net? - Thousands.
Also, all programmers (even the most experienced) are only human and prone
to error and in my opinion anything that makes it easy to write bad code
cannot be good.

Subject: Re: [PHP] Not Displaying From Vars??
Your description of register_globals is good, except that the security
risk is a matter of opinion. I would argue that register_globals only
presents a security risk to inexperienced developers.
The client can submit any data to your application regardless of any
configuration (and even regardless of language used). PHP's
register_globals provides a convenient mechanism for receiving data from
the client. In general, there are two types of data:
1. Data from the client
2. Data residing on the server
Code that allows data from the client to overwrite data residing on the
server is poorly written code, and this is the scenario that creates
this misconception of register_globals being a security risk. Data
residing on the server can be information in a database, session data,
etc. It is quite trivial to ensure that this data is overwritten. When a
script begins execution, the client can no longer submit data. It is
finished and can do no more so to speak. This makes things very easy.
Thus, consider this:
$logged_in=0;
if (is_valid($password))
{
$logged_in=1;
}
Guess what? The client cannot make $logged_in = 1 unless the password
they provide passes the is_valid() function (a function you create to
validate a password - just a hypothetical example). There is no way a
client can submit any data in between these statements. The problem is
when people fail to set $logged_in to 0 initially, so that a failed
password simply avoids the if statement but doesn't explicitly set
$logged_in to 0. This is poor programming.
For session data, try to override data that is initialized with
session_register() and see if it works. What you will find is that
whatever the client sends is overwritten by the data in the session, so
this scenario is also easy to avoid.
My point is that most risks can be avoided by understanding how the Web
operates and programming to the transactional nature of it. It is so
easy to make sure that the client cannot overwrite server data. I think
register_globals is far too often blamed for misunderstandings.

Re: Re[2]: [PHP] counting words in a string
You can get all the terms into an array using preg_match_all:-
$str = UNAVAILABLE More Info AVAILABLE More Info;
$regExp = /(?:UN)?AVAILABLE|More Info/;
preg_match_all($regExp, $str, $regs);
$regs[0] will contain the matched terms - you should then be able to use

Re: [PHP] Displaying full array contents
You could use recursion example:-
function printArray($arr) {
for ($i =0; $i count($arr); $i++) {
if (!is_array($arr[$i])) {
echo $arr[$i];
}
else {
printArray($arr[$i]);
}
}
}
$arr = array(Orange, Peach, Apple);
$arr2 = array(Banana, $arr, Pear);
$arr3 = array($arr, $arr2);
printArray($arr3);

Subject: [PHP] Displaying full array contents
I'm trying to write a function that will display the full contents of an
array. If one of the keys contains a value that is an array, the full
array (all indices) should be shown.
As an example, given the following definitions:
$Arr1[1] = Apple;
$Arr1[2] = Banana;
$Arr1[3] = $Arr2[];
$Arr2[1] = Carrot;
$Arr2[2] = $Arr3[];
$Arr3[1] = Orange;
$Arr3[2] = Peach;
the output should be:
Arr1:1:Apple
Arr1:2:Banana
Arr1:3:Arr2[]
Arr1:3:Arr2:1:Carrot
Arr1:3:Arr2:2:Arr3[]
Arr1:3:Arr2:2:Arr3:1:Orange
Arr1:3:Arr2:2:Arr3:2:Peach
The closest I've come is:
while (current($myArr))
{
if(is_array(current($myArr)))
{
$arrKey = key(current($myArr));
echo Array ;
echo nbsp=nbsp;
$baseArray = key($myArr);
echo key($myArr);
echo BR\n;
walkArray(current($myArr));
}
else
{
$arrKey = key($myArr);
if ($baseArray != )
{
echo $baseArray;
echo :;
}
echo $arrKey;
echo nbsp=nbsp;
echo current($myArr);
echo BR\n;
}
next($myArr);
}
This code only echoes one dimension of a multi-dimension array. I can't
find a way to reliably store more than that. Any suggestions?
Thanks in advance,

Re: [PHP] Displaying full array contents
Use a static variable in the function? A static var retains its value
between function calls
function printArray($arr) {
static $depth = 0;
for ($i =0; $i count($arr); $i++) {
if (!is_array($arr[$i])) {
echo $depth $arr[$i];
}
else {
$depth++;
printArray($arr[$i]);
$depth--;
}
}
}
$arr = array(Orange, Peach, Apple);
$arr2 = array(Banana, $arr, Pear);
$arr3 = array($arr, $arr2);
printArray($arr3);

Yes. I could use recursion, but what's really hanging me up is keeping

Re: [PHP] Session
PHP is automatically rewriting the URLs for the tags specified in url_rewriter.tags (php.ini) because the session cookie has not been accepted. I found it best to remove these tags and append the SID manually to the URLs that need it for when cookies are off - else SIDs can get appended where you don't want them appended. I think PHP's session system is really good and definitely worth learning.

Seems like there are a zillion options to choose from, lots of interdependent settings, etc, and I'm a bit confused on how to make it work. I try not to use session objects too much in any language as it makes the code somewhat less portable, but I did want to experiment with PHP's notion before launching off on another suite of apps. I'm starting with a simple fake hit counter that checks session to see if the counter was already dinged. It works if I turn on enable_transient_sid, but setting that drives ht://dig nuts by appending ?PHPSESSIDyaddayadda to the URL. Really makes a mess of the database :-)~~.

[PHP] Automatic Form Generation with PHP
Hi We are shortly to release the next version of Form Generator Pro (automatic generation of HTML form/PHP processing code) and are looking for some comments on the way in which we intend to make the software available. Due to the fact that we cannot distribute this PHP application without comprising copyright (the Zend Encoder is not an affordable option for us - we are a small start-up business), the current version of Form Generator Pro is only available for use online at the C U Online site which is fine because 1. it only generates mail forms and 2. it's free. However this won't work for version 2 because version 2 automatically generates forms for MySQL databases by querying the database for table information (field lengths, types etc). Opening up connections from our server to other servers to get database info is not an option - for security reasons (and also many MySQL servers are set up to only accept local connections anyway for this reason). To resolve this problem, the software has been split into 2 parts. The part that retrieves the database information sits on the customers server (secured). Field definitions are then extracted and sent to the generator which remains on our site. I will stress here that no actual database data is sent between the 2 servers, nor any MySQL server usernames or passwords - just the field lengths, types etc of the selected table. Access to the generator will then be sold as opposed to selling the actual software (although mail form generation will remain free). This is not an ideal solution but it seems to be the only way to make the software available and at the same time protect copyright. I would be grateful for any thoughts from other businesses/developers on this solution. Regards Debbie Dyer Software Engineer for C U Online
Re: [PHP] Getting a mysql set info
You need to use SHOW COLUMNS FROM table LIKE 'yoursetfieldname'
You can then retrieve the values from the [Type] column which will look

Re: [PHP] Re: Automatic Form Generation with PHP
Hi Henry Well the software generates the code to process the forms as well (eg for an insert form the code to check required fields are not empty, perform any data validation and insert the record into the db) as well as the forms themselves and this code is in PHP. You can choose to generate a sticky form where you would get 1 PHP page (containing a mixture of PHP and HTML) or non-sticky where you would get separate HTML PHP pages for the forms/processing. Because all this generated processing code is in PHP customers who don't have PHP either wouldn't be interested in the software or if they were interested in the software they would need to install it - both to use the software and also to be able to use the processing code that it generated.

Re: [PHP] Re: Automatic Form Generation with PHP
Hi Henry On set up of the side of the software that sits on the customers server a table is created for users. Adminstration screens are provided for adding/deleting users and a user can only gain access by logging in and they can only log in if a record exists in this table. The whole thing (on this side) is secured by cookies. After logging in the software attempts to connect to a MySQL database using the host, username, pass db name specified in a mysqlvars.php file - these vars are never passed across the network. No usernames/passwords either for MySQL or access to the software are stored in the cookie - the cookie is authenticated using a checksum value. The generator side is secured by sessions but again no MySQL vars are sent across nor any access usernames/passwords for the customer software. What is sent between the servers is: 1. the customers email address and password for the generator (encoded and different from their MySQL/customer software username/passwords) and. 2. table structure information which has been retrieved. This information could of course be intercepted but could be of no use to a hacker without a valid username and password for the MySQL database. If you disagree please tell me. It's this aspect of the software (security) that causes most concern as with any application enabling online access to databases.

You probably have magic_quotes_gpc in php.ini off on your Windows platform

Magic_quotes_gpc automatically applies addslashes to POST, GET and cookie

Use stripslashes to remove it or to write code thats portable - write a
