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.

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();

hello all,  i am having a for each problem.  im trying to get two post fields using the foreach function.

here is what i have in my form.php:
Code: [Select]
<?php
foreach($_POST['staff'] as $value) {
echo "$value -  <br />"; 
}
?>

the name of the the fields coming in are Code: [Select]
name='staff[]'   and the second one is name='descr[]'
fields += 1;

Sorry for the really, really basic CSS question. (I'm asking this in the PHP forum, because so far, you've all been nice to me and haven't made fun of some of my really dumb questions.)  

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 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.

Major breakthrough.  utf8_encode() allows me to view utf-8 characters in the browser.  Therefore, my source data file must be ISO-8859-1 encoded text, right?   Am I understanding this correctly?

<?php
//mb_internal_encoding("UTF-8");
header('Content-type: text/html; charset=utf-8');
$file = fopen('some_csv_file_created_by_excel.csv', "r");
ob_start();
while (($spec = fgetcsv($file, 100000, ",")) !== FALSE){
    echo($spec[0].' '.utf8_encode($spec[0]).'<br>');
}
$string=ob_get_clean();
?>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <title>utf</title>
    </head>
    <body>
        <p><?php echo($string);?></p>
    </body>
</html>

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.

Hello. I'm trying to pull information out of an xml file. However I'm a bit lost in getting the actual value.

Code: [Select]
$url="http://ws.audioscrobbler.com/2.0/?method=artist.getimages&artist=Dr%20Feelgood&limit=1&autocorrect=1&api_key=c107c9b5c09cb5693b6c19409dd984c1";

$xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA);

$largesquare=$xml->images->sizes->size[2];
Is what I have but its not pulling the information. The above url will give you the link to a set xml file for this example. And I want to get the info for the

Code: [Select]
<size name="largesquare" width="126" height="126">http://userserve-ak.last.fm/serve/126s/43173899.jpg</size>
I'm sure I'm doing something wrong that's a simple fix but I am lost here. In the sizes there are 6 different size options each with different names and I have no idea how to pull the one with the correct name that I need.

Thank you to who ever can help me sort this out.

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?

In php, which function is best used to act something like the sql "LIKE" command? and how would that function be used like?

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.

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.
