PHP - Question About Using __get()

Looking at a forum like PHPbb or similar. Wondering if anyone can tell me how the system (or scripts) manages to pull all the user information when viewing a thread without a massive amount of database calls? For example, lets say 1 thread has 10 different users associated to it. When you view the thread, on the left you see the username, their avatar, when the membership was created, maybe even the users level or amount of interaction. So, for each thread view (or page view) does the program do a SQL Select back to the user database for each user's information or is the users information being pulled from cache somewhere?

Any insight into the logistics is greatly appreciated!

I'm considering getting a VPS, but I'm not entirely sure what this would be able the handle. The specs doesn't look that good to me, but my friend swears it will handle running apache/php/mysql handling large websites and databases without a problem. I want to run multiple databases that just store statistics and I'm a bit worried about the RAM and the company doesn't even mention a cpu.

Here's the specs:
256MB RAM
300GB HDD
10Mbps unmetered
1 IP Address

My friend runs two counter-strike: source servers off his VPS (same stats).. so I'm actually considering this, but it just seems like it's not powerful enough.

Oh.. forgot the most important part.. it's only $9.

I have an issue with the below code

Code: [Select]
if ($gtype == "%24L" || $gtype == "$L")
The value actually starts with the dollar sign then L, but its being read as a variable that's not assigned so it showing as blank. so the question is how to I get to check and see if the value of gtype actually is $L in a way that it wont read $L as a variable and as a value instead?

i am looking for a way to write a php script to pull information from a html table and put that information in to the databases  does any one have any idea who to do this

I am trying something simple, creating some horses and making them race using OOP, creating them is easy, how can i find out which one "won" based on the highest total. Here is what i got so far

Code: [Select]
<?php

class Horse
{
   public $strength;
   public $speed;
   public $agility;         

        public function create($name,$age,$odds){
            $this->name=$name;
            $this->odds=$odds;
            $this->strength=(rand(50,200) * $this->odds - $this->age);
            $this->speed=(rand(100,400) * $this->odds - $this->age);
            $this->agility=(rand(150,250) * $this->odds - $this->age);
            $all=array(0=>"$this->strength",1=>"$this->speed",2=>"$this->agility");
            echo "<b>$this->name</b> has a strength of <b>$this->strength</b>, a speed of <b>$this->speed</b> and agility at <b>$this->agility</b>. --- <b>".array_sum($all)."</b><br>";
        }
}

$mix=rand(2,6);
$a=new Horse;
  $a->create("Dave",  2, $mix);
  $a->create("Dude",  3, $mix);
  $a->create("Evan",  3, $mix);
  $a->create("Jill", 15, $mix);
  $a->create("Flex", 10, $mix);

?>

I cant figure out a way to find out who had the highest total, i would love to know what i am doing wrong.

I have been away from PHP for a long time and I was looking over my old scripts. I did PHP OOP at one time and I used a paticular method to connect all my methods up and load them. I have been looking at other peoples code and when I look at my code it does not even feel like OOP, I want to know how to you link all the methods (or is it called functions?) in a class up and return them? I use to do this:

Code: [Select]
<?php
class quickFUNC
{
 
function note_pad()
{
// code for notepad
}
 
function quickAdminFunc()
{
// code for admin func
 
$this->note_pad();
}
 
 
}
 
$quickFUNC = new quickFUNC;
 
if(isset($_GET['id']))
{
$act = $_GET['id'];
}
else
{
$act = NULL;
}
 
switch ($act)
{
 
 
case 1:
 
//some random code to launch case 1
 
break;
 
default:
$quickFUNC ->quickAdminFunc();
 
 
?>



This was my code back in the days, as you can see the notepad was called in the admin function then made the admin function default in the case switch.  I looked at all my script and the all are layed out like this :S..

Can I get some help please, thank you.

hi php people,

I am wondering will  if the code below will work when I call $C->getafoo() will I get foo;  I keep getting an error at this point  return $this->A->a(); saying  the method is not there

Code: [Select]
class A{
  public function a(){
    return "foo";
  }
}

class B {
  public $A;

  function __construct($A) {
    $this->A = $A;   

  }

  public function geta(){
    return $this->A->a();
  }
}


class C extends B{
  public function getafoo(){
   return geta();
 }

}
$C = new C(new A());

echo $C->getafoo();

Code: [Select]
<?php
if ($News_1_Status=="Y")
echo <div class="newstitle" align="left"><?php echo $News_1_Date;?>&nbsp;&nbsp;<a href="<?php echo $News_1_URL;?>"><?php echo $News_1_Name;?></a></div><br>;
else
echo "Have a nice day!";
?>
how do i get the above script working any clue?

Hi,

I am looking into a way of adding addons to a class I made.. I thought something like this would work, but not sure how to implement it:

Code: [Select]
<?php
class foo {
    function foobar($text) {
        $text = $text . 'b';
        return $text;
    }
}
class bar extends foo {
    function foobar($text) {
        $text = $text . 'c';
        return $text;
    }
}

$var = new bar();
$var->foobar('a'); // this would then return abc
?>

Now i want to be able to call up foo, and it calls the foobar of foo, and the foobar of bar.
is that possible?

hosh

Im not new to php but I am trying to think if this possible.

I want to write a php script that creates a div inside a div until lets say 10 divs are created.

I have been trying do while statements but them seem to place them underneth each other not within.

I want
<div id=one">
<div id=two">
<div id=three">
</div>
</div>
</div>

Only thing I can create is

<div id=one"></div>

<div id=two"></div>

<div id=three"></div>

Like I said  I dont even know if this is possible or if I am just retarded and can't think of a way to do it but it would be nice to see what others have to say about it.

Hello, i am currently working on a project and i have been on google and nothing has helped i am trying to detect characters in the URL so for example XSS if someone typed in the URL:

home.php?=<script>document.cookie();</script>

OR

home.php?=<?php echo file_get_contents("document.txt", "a");

How would i be able to make a kind of firewall to detect this?   and if it does then redirect to another page.   Thanks.

Hello,

I have a 'strange' situtation.
I have this string "Who Am I" that will be used as an header (site for a client) but the design shows that the word "Who" and the words "Am I" are in 2 different colors, in HTML this is a quick fix, but in PHP?

What I was thinking was explode the string and fetch the first element put it in a var en then concat the 2 others.
But what if the title is more then 3 elements after exploding? It needs to be more dynamic, but I don't know how to do it.

Does anyone have an idea?

U guys know in forums how at the top or bottom there links to the "1 2 3 4 5 next" and stuff? and how it loads a database? how would i do that exactly? or explain to me what it could be called. cause me i have no idea :/

I am trying to make it so that it will load if the site if the site is online(EG. $siteonline = 1), and so on. I can't seem to think of how I could do this so it will work from the very top of the page's html, to the very bottom.

Like the following code is meant to list all of the stuff in that database.
<?php
$list_q = mysql_query("SELECT * FROM settings") or die (mysql_error());
while($list_f = mysql_fetch_assoc($list_q)) {
}
?>

I have my page laid out like this..
<?php 
include "includes/connect.php";
include "includes/config.php"; 
?>
<?php
    $list_q = mysql_query("SELECT * FROM settings") or die (mysql_error());
    while($list_f = mysql_fetch_assoc($list_q)) {
?>
Html content etc..
<?php 
}
include 'includes/footer.php'; ?>

But if I do it that way, It only displays what is in footer.php.
