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();

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!

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.

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.

i am trying to understand, how a site like ebay can display content and be case insensitive?
for example:
  The original url:

http://www.ebay.co.uk/itm/Toshiba-Satellite-C50-AMD-E-Series-1-4GHz-Dual-Core-15-6-Inch-500GB-2GB-Laptop/151458954958

the above works fine and go to the intended page.

user editing the browser url into lowercase :

http://www.ebay.co.uk/itm/toshiba-satellite-c50-amd-e-series-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958

random uppercase and lowercase.

http://www.ebay.co.uk/itm/toshiba-sateLLite-c50-aMd-e-sERIes-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958

both the urls above also work fine and go to the intended page.   How can such a thing can work? it is supposed to throw an error such as page not found and the like?

any thoughts welcome.

Code: [Select]
    /*** a new dom object ***/
    $dom = new domDocument;

    /*** load the html into the object ***/
    @$dom->loadHTML($file);

    /*** discard white space ***/
    $dom->preserveWhiteSpace = false;

    /*** the table by its tag name ***/
    $tables = $dom->getElementsByTagName('table');

    /*** get all rows from the table ***/
    $rows = $tables->item(0)->getElementsByTagName('tr');

    /*** loop over the table rows ***/
    foreach ($rows as $row)
    {
        /*** get each column by tag name ***/
        $cols = $row->getElementsByTagName('a');
        /*** echo the values ***/
        echo $cols->item(0)->nodeValue.'<br />';
    }
Hi, Is there a way to start to echo from 43?
thanks.

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.

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.

hi, im trying to say if field ARTIST = Eminem then do the following.  here is my current code

Code: [Select]
$hmm = simplexml_load_file('http://localhost/1.0/?method=player.getPlayQueue');


foreach($hmm->tracks->track as $tracks) {
    $artist = $tracks->artist;
    $title = $tracks->title;
    $album = $tracks->album;
    $index = $tracks->index;
$id = $tracks->id;

//If we submitted the form
if('.$artist.'="eminem")
{

echo '<table border="0" width="70%" align="center">';
echo '<tr>';
i just need to know how to do the if(***) part.

thanks.

are there any php functions that are best used when testing to see if a server is busy or not? and if the server is busy then display a "server is busy" message in the php script?
