PHP :: Store Classes In An Array?

Get Data From The Db And Store It In An Array
I want to have an input field in my Admin CP when you are creating a Forum where you can input a list of numbers (member ids) seperated by commars, like this:

Quote1,6,4,8,2
These will be the ids of people who can moderate the Forum and will be stored in the db along with all the other stuff like forum name/description etc.

That's easy enough.

Now my problem is I need to get that from the db and store it in an array... basically so I can do something like:

<?php
if(in_array($_SESSION['mem_id'], $forum_moderator_array)) {
echo('Congratulations, you are a forum moderator.');
}
?>

How can I go about doing this?

Store A Array As A Variable
is there any way that i can store a array as a variable because i dont want to creat a database for thousands of variables. heres what i thought of so far

<?PHP

$array = array($arrayval);

What's The Best Way To Store An Array In The Database
I am trying to build a simple tree menu where the main items can be either a link or open up a subList of items which themselves can belinks or open into more submenus and so on.
An example is:

$ar = array(
'new_user' => 'newuser.php',
'tst1' => array(
'subtst' => 'subtstlink.php',
'subtst2' => 'sublink2.php'
),
'heyhey' => 'heyhey.php',
);

I am wondering what is the best way to store that in a mysql database (Both the item name and the link to it). Is there any php function that will allow me to make such an array into some sort of variable (String?) which can then be read easilly and made back into the array for manipulation and creation of the tree menu?

Static Classes Vs. Singleton Classes Vs. Globals
Sometimes I want to use certain data and functions anywhere in my code;
for example, when writing logging routines. In PHP5 I could write a
class with all static members and functions, a singleton class, or a
regular class assigned to a global variable. What would be the
advantages of each?

In Java web-apps (or in non-web applications), these classes persist
for much longer, so it's easier to see the reasons for using them. But
in PHP, it seems like you could do pretty much the same thing with all
three.

PDF , Classes, And PHP
I'm stuck at first base here. Currently working on turning a rather static PDF building script into a more modular, OO PHP app.

I have scaled this example down to the bare bones, trying to see what the heck is going wrong. It recognizes that is should spawn a pdf file, but then there is just no data. Nothing, no error, no helper app.

I'm only a week or so into PDFs and only a couple of days into OO with PHP, so I'm on the lookout for the obvious. I do have PHP/PDF apps that run fine off the same system.

Here is the class:
<?
error_reporting(E_ERROR);
/********************************************
pdfReport.class.php - description
********************************************/
/*
common functions / classes
*/
//class used to build rectangles - how exciting (-:
class pdfReport{
//define our common properties
//page properties
var $pdf;
function createPDF() {
header("Content-type: application/pdf");
header("Content-Dispositions: filename=report.pdf");
$this -> pdf = pdf_open();
pdf_begin_page($pdf, 612, 792);
}//end function createPDF
function closePDF() {
pdf_close($pdf);
}//end function pdf_close
function buildText() {
pdf_set_font($pdf, "Times-Roman", 15, "host");
pdf_show_xy($pdf, "Active Case Review Quarterly Report", 25, 780);
pdf_set_font($pdf, "Times-Roman", 26, "host");
}//end function buildText
}//end class
?>
And here is the page where I call the class:
<?
include("test.class.php");
//error_reporting(E_ERROR);
//create a report
$quarterlyPDF = new pdfReport;
$quarterlyPDF -> createPDF();
$quarterlyPDF -> buildText();
$quarterlyPDF -> closePDF();
//end pdf document
?>

thanks much for any input.

Value Of PHP Classes?
So PHP classes are pretty cool. But what is the value they provide? I understand the value of OO, but in the PHP environment, every class you instantiate lives only in the span of that request. There is no concept of singleton classes, or classes that remain across requests. The notion of allocating new memory for every instance of a class for every request seems wasteful. Thoughts?

Why Uses Classes?

Use And Need Of Classes In PHP
I know what object oriented programming is - I know what classes are and how they work - I'm just trying to figure out when they should be used in PHP...

I have two questions:

1-How do you keep your objects? For example if we had a shopping cart, would we create a new shopping cart object and everytime the user adds/removes items update that same object? and how would you keep that object's information as the user browses through the site? Would you use serialize/unserialize session variable functions? or is there a better way?

2- For example, if we have a website that has users why would we want to make a "Users" class containing all the user information? Can't we just insert/retrieve data directly from the database? and when we get the data from the database what exactly is the point of creating an object out of them when we can just print it out? I guess my question is why would having a Users class be useful in a php web application? (assume users have name, username, password, address, etc.)

Using Two Classes
Lets say I have one class that deals with the database (class called SQL), a class that manages the user authentication (class called User) and another class that does something like getting all the options from the database for a poll (class called Options). The class Options is extended by another class called Poll which is extended by the class called Gateway, like this:

class SQL {}
class User {}

class Gateway {}
class Poll extends Gateway {}
class Options extends Poll {}

$sql = new SQL;
$sql->connect();

$user = new User;
$user->authenticate();

$poll = new Options;

As you see, SQL and User are in no way connected to the other classes, however sometimes I'd like to use SQL inside the Options class. Would it be better to use global inside one of Options' function, like this:

class Options {
public function __construct() {
global $sql;
$sql->query();
}
}
...or would it be better to let Gateway extend Users and SQL, like this:

class SQL {}
class User extends SQL {}
class Gateway extends User {}
class Poll extends Gateway {}
class Options extends Poll {}
// etc...

When To Use Classes
I've been developing websites using PHP for several years now, yet have never used OOP concepts. I am familiar with them, but have never had a need for them in my projects. However, I am now interested in using them to expand my knowledge, but unsure when they are really needed.

Lets say I have a MySQL database with a "customer" table that stores all their information such as name, address, phone number, etc. The web page will do basic queries on the customer info, inserts, updates, selects, and so forth. I'm trying to incorporate classes with this, yet it seems like it's a lot more work than if I were simply using function to perform the actions on the database. I did some browsing on the web and it doesn't seem like classes are really needed when your dealing with data from a database (other than possible a class to connect to the db). Is this true? Any examples maybe?

PHP Classes
Today I looked at the documentation for PHP classes and now I would like to rewrite a member system and content mangement system using classes. In the past Ive used classes in java, and PHP seems very similar other than some syntax stuff.

My primary concern with using classes is that if I wanted to make each member an object would it be possible to store that object in a mysql database, or would I have to have a method within my class to get all the data from the object and put it into the database, and another to then later get the data from the database and construct the object.

PHP And Classes
Specefically, how do they work? php.net describes them as a collection of variables and functions working with these variables. So far I'm doing this with collections of function and include'' statements. For any given operation, a link will include a $_GET['thing'] variable. The index then have:

if ((isset($_GET['thing'])) && ($_GET['thing'] == "linkname")) {
include 'useful_pile_of_functions.php'
}

This method seems to me to be somewhat like using includes as classes, as the called file contains everything needed to support the users desired function. How is using classes better than this method?

Problem With Classes..
Has anyone had problems with PHP returning two different results on different machines when using classes?

Here's the scenario:

On win2k/IIS/PHP 4.0.3, I set up a class like this:

class myClass {

var $thisVariable = "test";

function getVariable(){
$this->variable = $thisVariable;
echo $this->variable
}

}

When I instantiate it, it returns "test" but when I upload the file to my website server, which is Apache running PHP 4.0.2, it refuses to return anything.. but when I set it like this:

class myClass {

var $variable;

function getVariable(){
$this->variable = "test";
echo $this->variable
}

}

It works just fine. Any idea why?
