Re: [PHP] Best way to use other objects within classes?
Hi,
Friday, June 3, 2005, 5:16:19 AM, you wrote:
MP Hi All,
MP I'm using the MDB2 object to access my MySQL database. I have a number
MP of classes that perform page-building activities that need db access,
MP and I'm wondering what the best way to expose the MDB2 object to them is?
MP (Note: my development environment is PHP 5.0.3, but the production
MP environment is 4.3.10. This is my first project built with 5.x local and
MP 4.1.x remote, so if anyone with more experience spots any fatal flaws
MP where I'm using 5.x specific methods etc, I'd appreciate knowing about them)
MP Currently, I'm instantiating the MDB2 class in my main page, then
MP passing it as an object reference to each of the other classes that
MP require it.
MP A simple representation of my main page and a class would be:
MP ?
MP $db = connectMDB2(); // function that returns instantiated MDB2 object
MP $comments = new displayComments(); // class that performs displaying
MP of comments
MP $comments-set_db($db); // passing the MDB2 object to the class
MP $comments-doSomethingElse();
?
MP The displayComments() class might then look something like:
MP class displayComments{
MP private $db;
MP public function set_db($db){
$this-db = $db;
MP }
MP public function doSomethingElse(){
MP $sql = SELECT something FROM sometable;
$rs = $this-db-query($sql);
MP while ($row = $rs-fetchRow(MDB2_FETCHMODE_OBJECT)){
echo $row-something.br /;
MP }
$rs-free();
MP }
MP }
MP My main page calls on at least 8 or 9 such classes as it is being built,
MP and I'm concerned that I may not be handling the MDB2 object in respect
MP to them in the most efficient way possible. In a way, I guess this isn't
MP specifically about the MDB2 package, but more about how to handle
MP objects when they are required within classes.
MP I'd very much appreciate any comments or advice anyone might be able to
MP give.
MP Much warmth,
MP Murray
My solution to this problem was to write a class loader and to call it
whenever I needed a particular class. I give each instance a name and
the loader checks if an instance of that class, that name exists. If
it does it returns a reference directly, if not it loads the class
and then returns the reference. This way I don't have to worry about
passing references around. It is a little more complex than that as I
also check if the class was passed the same variables, if not it calls
the constructor again. Let me know if you want to try the code (only
tested on php4)

The debate between storing includes outside of document root versus using a .php file extension, instructing Apache to process .inc files as PHP, instructing PHP to deny requests for .inc files, etc. I agree regarding code on your own server/project. I do believe that the situation is another when you are manager of some project where your php code is being distributed to several different systems beyond your control (think phpmyadmin, phpnuke, etc. - maybe not the best examples regarding security record, though :-) In that case, one could create some requirements regarding the installation of the php application that some customers at web hosting companies might not be able to follow (e.g. create a .htaccess denying .inc-files, create folders outsite of webscope), or one could make a trade-off between ease of installation and highed security. One way of achieving this could be the sole use of .php-extensions (and code constructed in a way that direct access would cause no harm). I believe that there is reason to differ in these two cases for practical reasons. In the latter case a lot of assumptions could cause damage. Poorly implemented high security could be worse than moderate, application based security. -- - Peter Brodersen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Site Design Strategy
asinning wrote: This is my first post to this group. I've been trying to figure this out on my own, but I keep running into complications, so I've decided to get some help. Much thanks for any help! I've been writing php server application for a couple of years, but now I'm turning my attention to re-building our company's aging website. This is a big project and is going to require a solid foundation. At the crux of this post is the following question: How do you develop a very robust, dynamic web-site, but also allow non-technical people to contribute? There must be an easier way. Here are my working assumptions and my strategy. Please help me if I'm thinking down the wrong path. Assumptions: 1) Non-technical people in the company need to be able to build pages, and they should be able to post their pages without bothering me. We have a tech-support person who will be able to help them, but she has zero programming knowledge and only a superficial understanding of HTML. 2) Every page needs to reside within he shell of the web site. This includes header(the top-level menu) left-side menu (a dynamic, context-specific menu) content (this is what the non-technical people will produce) footer (your standard fare text-based links) 3) I don't want to use frames, and I don't want to use Dreamweaver templates. Strategy: Currently, I am working on the following model: There is a top-level index.php page. This is the target of EVERY page on the site. The page that gets loaded in depends on the parameters of query-string. It's very simple, if the query string reads ?target=products/gsp, then my php will look for a site-relative document such as products/gsp.htm OR products/gsp/index.hml. Then, this document will get included as the content in my shell. Well, this works to a degree, but it requires that people use site-relative paths for all of their graphics and links, which is way, way to much to ask. After all, people are using WYSIWIG editors such as Dreamweaver and even Word to build their pages. Typically, site-relative paths don't work in these environments. They shouldn't need to upload their document to preview it. It also requires that they put their page within a 550 pixel wide -td- tag. I'd love to drop that requirement. So, now I considering the following: A parser that will convert any content into includable form. Relative paths will be translated to the site-root, etc. I'm a bit stuck here. Maybe I've misunderstood but here's a thought: I'm not sure what they're actually doing with these pages but it's usually in my experience something like a headline, a block of text in which you can allow certain HTML tags (you can use tidy within PHP) and some images and some links. Is there more that these folks are doing? Is there a reason to give them so much flexibility in design? Are these home pages as in personal showcases or department-specific offerings? You probably want to set up each user with their own directory or db area so they can upload all their images through your control panel, enter their text and have everything in one place for each user. If you give users the opportunity to put in unlimited matched sets of Headline, text block, image float right left or center (cna cation if required) plus strong, em and a limited href capability 99% of people will probably be happy. Make sure you rename all images they upload to remove spaces, weird characters and duplicate names. You can use a naming convention like user.image.x. or even md5(imagename). So this way, each user gets a user directory in which all image links are relative to that directory, all images are righ there and ties to the user. It also requires that they put their page within a 550 pixel wide -td- tag. I'd love to drop that requirement. AAARG. We use a wrapper in XHTML, putting everything in div tags so that later, when we change the format, they're not stuck in a td as you rightly worry about. Using div and CSS positioning increases exponentially your flexibility both now and later. And requires fairly modern browsers but according to our logs almost everyone has them. And if they come in using lynx it'll still *work* in that they get all the info in sensible order. Netscape 4 and IE 4 users are out of luck, but then, they often are anyway in terms of support on the web (please let's not devolve into a flame war over that statement).

Anyway I am not sure how to capture the HTTP request and pass it to the relevant objects. Is there a generic way developers process the request to call the classes and generate the needed objects in PHP5? I'd use $_REQUEST if I were expecting to access both $_GET and $_POST arrays frequently/equally. __autoload() is pretty handy, keeps you from writing tons of include statements. I agree with Greg. Although I would add that if you are using GET / POST arguments to determine which pages to include then you minimally want to filter to be sure they don't try to read sensitive files (/etc/passwd, My Documents, and the like). And since I'm paranoid I might also want to escapeshellarg() the $_REQUEST variable you're using. -- Teach a man to fish...

explicit in passing by reference in my code wherever I've needed to access

Hi Chris,
Thanks for replying
I noticed a site that is using php, but he is has shortened
the url so that the filename was not shown..
eg:
somesite.com/?a=1
How did they do that?
It's called a directory index. Examples include index.html and
index.php. You configure this with the DirectoryIndex directive in
httpd.conf.
I did see the directory index in the httpd.conf file, but let me explain a
bit more about what
I am trying to do.
Basically I am waiting for the client to pay me...till he does, I am
displaying the index page which
is a under construction page...but he also wants to play with the site so I
need to direct all calls
to main.php...but i dont want to show the client that he is going to
main.php so I wanted to use
it like this clientssite.com/?do=blah
Personally I reckon you should just enable the page. Once it is
already online, particularly if he has visitors, then it going offline
will be more expensive for him, than if it were never online.
Having that said, you could simply password protect it and give him
the password, or else require that any unauthorised IP's view the
under_construction page, whilst, an authorised IP will view the
correct page. This could be a simple if ($_SERVER['REMOTE_ADDR'] !=
'whatever'){ die(This page is under construction);
Thanks,
Ryan

Re: [PHP] How to find random records in a subset?
On Thu, June 2, 2005 4:31 pm, Brian Dunning said:
I am using a routine to find 50 random records in a large MySQL
database (about a million records) where I generate a list of 50
random unique ID's, and then use MySQL's in command to find them. I
can't use order by rand() due to its performance hit.
But I have to take it one more step: I want to first limit my found
set to those matching a different search criteria, and then find 50
of those.
If your search criteria is on an indexed field, you may find that the
order by rand() is much much much less of a problem once you winnow your
record set down to the search criteria.
Or, more precisely, if your search parameters get you a small result set,
the order by rand() will be fast because that is done AFTER the smaller
result set is determined.
If your search parameters get you a HUGE set, order by rand() not so fast.
Anyone? Can this be done all within MySQL, or is it going to require
some humongo PHP arrays?
How do you generate a list of 50 random unique IDs in the first place?
How to you guarantee that all those IDs are in the database?
What if a record gets deleted?
I suppose *ONE* option to try would be to just get the full result set,
and then use PHP's mt_rand() to skip forward/backward a random number of
records, using something like:
//untested code
$count = mysql_num_rows($result);
$ids = array();
while (count($ids) 50 count($ids) $count){
$random = mt_rand(0, $count - 1);
mysql_data_seek($result, $random);
$id = $result['id'];
//Note use of $id as key, so duplicates are ignored.
$ids[$id] = $id;
}
This will perform MISERABLY when your number of records is closer to 50.
It would be okay only if all searches result in tons and tons of records.
One does have to wonder:
If the user has put in multiple search criteria, why order randomly? Why
not put best matches first?

Re: [PHP] How to find random records in a subset?
Richard Lynch [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
How do you generate a list of 50 random unique IDs in the first place?
By using the SQL function to create those randoms
How to you guarantee that all those IDs are in the database?
No need for that. When you do 'order by rand()' SQL understand that you
are adding an extra, unnamed column which contains the value of the function
rand(). Since rand() is, of course, random, the records are ordered in
arbitrary ways. Then you take the first 50 or whatever of those randomly
sorted records. The problem is that to do so, it will have to read
sequentially all of the table to assign each record a random number, and
then sort those. It works for short tables, it is a killer for big ones.
Once upon a time, on a table with an autoincrement field, I first fetched
the minimum and maximum current value of that autoincrement field. Then I
did individual one-record selects (limit 1) with the key equal or greater to
a set of randoms created within those minimum and maximum value. Since two
randoms could produce the same record, I checked the key of each resulting
record against an array which had the primary keys as key. When the count()
of that array reached the number of records I wanted, I was done. This was
for a very little subset of a really large table and in those circumstances
it was faster than the other way.
satyam
What if a record gets deleted?
I suppose *ONE* option to try would be to just get the full result set,
and then use PHP's mt_rand() to skip forward/backward a random number of
records, using something like:
//untested code
$count = mysql_num_rows($result);
$ids = array();
while (count($ids) 50 count($ids) $count){
$random = mt_rand(0, $count - 1);
mysql_data_seek($result, $random);
$id = $result['id'];
//Note use of $id as key, so duplicates are ignored.
$ids[$id] = $id;
}
This will perform MISERABLY when your number of records is closer to 50.
It would be okay only if all searches result in tons and tons of records.
One does have to wonder:
If the user has put in multiple search criteria, why order randomly? Why
not put best matches first?

Re: [PHP] Site Design Strategy
Here is what I use:
The articles (non-technical user supplied content is stored in a database
e.g. mySQL with a table named something like article_content). The table
has columns such as
CREATE TABLE article_content (
id int(11) NOT NULL auto_increment,
page_name varchar(35) NOT NULL default '',
side char(1) NOT NULL default '',
position int(2) NOT NULL default '0',
title varchar(35) NOT NULL default '',
leader_length int(11) NOT NULL default '0',
creation_time datetime NOT NULL default '-00-00 00:00:00',
last_edit datetime NOT NULL default '-00-00 00:00:00',
editor int(11) NOT NULL default '0',
content longtext NOT NULL,
PRIMARY KEY (id)
) TYPE=MyISAM;
Each user is assigned a security level in a user database that grants them
access (table name something like 'editors')
Each article has an hidden (no decoration) editor's link at the end of the
article. It could be the last word, the final punctuation, or a graphic.
When you click the editor's link the user is challenged against the user
name and password in the database and appropriate data stuffed into
sessions.
Once authentication is complete the article content is delivered for editing
via a JavaScript CMS such as xinha or tinymce.
Upon completion of editing, the content is stuffed back into the database.
The template for all the website is as follows:
require('/home/pathtofile/phplib/class.articles.php');
require('/home/pathtofile/pieces/header.txt');
require('/home/pathtofile/pieces/column1.txt');
require('/home/pathtofile/pieces/column2.txt');
get_article(L);
require('/home/pathtofile/pieces/column3.txt');
get_article(R);
require('/home/pathtofile/pieces/footer.txt');
The function get_article() pulls the content from the database for the
referring page (e.g index.html) where the page_name matches the referrer and
the side matches L or R. I use position to rank the articles on the page.
A page with lower position (e.g. 1) gets displayed first and then any 2
articles, then 3, etc. I use the 0 as a 'non published' indicator which
allows an editor to work on an article and then hide it until the right time
or to repost a recurring article at certain times..
Works wonderfully well and elevates my perceived status to that of near
genius!
Here is a link to see it in action or at least to see the finished content.
The entire web site is maintained by non-technical volunteers and they have
populated hundreds of articles on dozen of pages.

Subject: [PHP] Site Design Strategy
This is my first post to this group. I've been trying to figure this
out on my own, but I keep running into complications, so I've decided
to get some help. Much thanks for any help!
I've been writing php server application for a couple of years, but now
I'm turning my attention to re-building our company's aging website.
This is a big project and is going to require a solid foundation.
At the crux of this post is the following question: How do you develop
a very robust, dynamic web-site, but also allow non-technical people to
contribute? There must be an easier way.
Here are my working assumptions and my strategy. Please help me if I'm
thinking down the wrong path.
Assumptions:
1) Non-technical people in the company need to be able to build pages,
and they should be able to post their pages without bothering me. We
have a tech-support person who will be able to help them, but she has
zero programming knowledge and only a superficial understanding of
HTML.
2) Every page needs to reside within he shell of the web site. This
includes
header(the top-level menu)
left-side menu (a dynamic, context-specific menu)
content (this is what the non-technical people will produce)
footer (your standard fare text-based links)
3) I don't want to use frames, and I don't want to use Dreamweaver
templates.
Strategy: Currently, I am working on the following model:
There is a top-level index.php page. This is the target of EVERY
page on the site.
The page that gets loaded in depends on the parameters of
query-string. It's very simple, if the query string reads
?target=products/gsp, then my php will look for a site-relative
document such as products/gsp.htm OR products/gsp/index.hml. Then,
this document will get included as the content in my shell.
Well, this works to a degree, but it requires that people use
site-relative paths for all of their graphics and links, which is
way, way to much to ask. After all, people are using WYSIWIG editors
such as Dreamweaver and even Word to build their pages. Typically,
site-relative paths don't work in these environments. They shouldn't
need to upload

[PHP] Help with some OOP
Hello all, Ive been working with PHP for my websites for a few months,
just attempted to build my own class, after reading all this stuff about
automated robots and XSS attacks etc decided to step up security a
bit, my result is an attempt to create a class for using the token
method within web forms, not even sure whether its the real thing but my
work is below, some advice on whether its ok or what needs improving
would be appreciated, thanks.
?php
// PHP 4.3.11
class SecretToken {
var $_returnCode;
function GenerateToken() {
if(!isset($_SESSION['token'])) {
session_regenerate_id();
$new_token = md5(uniqid(rand(), true));
$_SESSION['token'] = $new_token;
}
}
function VerifyToken($post) {
if(isset($_SESSION['token'])) {
$saved_token = ($_SESSION['token']);
}
if($post == $saved_token):
$this-_returnCode = 1;
unset($_SESSION['token']);
else:
$this-_returnCode = 0;
endif;
}
function ReturnCode() {
## Result will be 1 for success or 0 for fail
return $this-_returnCode;
}
// end class definition
}
?
Basically in my web form I call GenerateToken firstly, then when the
forms been submitted I then call VerifyToken and finally check return
codes using a switch statement, seems to work,
TIA
