Zasto ispisuje vrednosti i kljuvceve niza u definiciji niza?

^{20.04.2007. u 15:57 - pre 207 meseci}

Evo kod i nije mi jasno kada pozovem ovu klasu i metodu Display() urdi se sve dobro samo uporno ispisuje vrednosti i kljuceve na html stranici. Upitanju je niz $buttons?

stvarno mi nije jasna ova stvar

Code:

<?php
class Page{
    //atributi klase Page;
    public $content;
    public $title='TLA Consulting Pty Ltd';
    public $keywords='TLA Consulting, Three Letter Abbreviation some of my best friends are search endiges';
     public $buttons=array('Home'    => 'home.php',
                         'Contact' => 'contact.php',
                         'Services' => 'services.php',
                         'Site Map' => 'map.php');


  public $bt=array('23','2321','4');

    public function Display(){
         echo "<html>\n  <head>\n" ;

       //echo "Velicina niza ".count($this->buttons)."\n";
       //echo "Velicina niza ".count($this->bt)."\n";
       $this->DisplayTitle();
       $this->DisplayKeywords();
       $this->DisplayStyles();

       echo "</head>\n<body>";
       $this->DisplayHeader();
       $this->DisplayMenu($buttons);
        echo "</body> \n </html>";
  }


  public function __set($name,$value){

       $this->$name=$value;

  }

  public function DisplayTitle(){
      echo '<title>'.$this->title.'</title>';
  }

  public function DisplayKeywords(){

      echo "<meta name=\"keewords\" content=\"".htmlentities($this->keywords)."\" />";
  }

  public function DisplayStyles(){
  ?>
  <style>
  
   </style>

  <?php
  }

  public function DisplayHeader(){
  ?>
      <table width"100" cellpadding="12" cellspacing="0" border="0">
            <tr bgcolor="black">
                <td aligne="left">  <img src="slk/logo.gif">   </td>
                <td>
                    <h1> TLA Consulting Pty Ltd <h1>
                </td>

                <td aligne="right" > <img src="slk/logo.gif"> </td>
            </tr>
     </table>

  <?php
  }

  public function DisplayMenu($buttons){

      echo "<table width='100%' bgcolor='white' cellpadding='4' cellspacing='4'";
      echo "<tr>\n";
      //izracunavanje velicine dugmeta
      $width=100/count($this->buttons);

       foreach ($this->buttons as $name=>$url)
          $this-> DisplayButton($width, $name, $url, !$this->IsURLCurrentPage($url));

       echo "</tr>\n";
       echo "</table>\n";
   }

   public function IsURLCurrentPage($url){

          echo 'Urls='.$url.'';
          if(strpos($_SERVER['PHP_SELF'],$url)==false){
              return false;
          }
          else{
              return true;
          }

   }


   public function DisplayButton($width, $name, $url, $active=true){

        if($active)
            {
                echo "<td width='".htmlentities($width)."%'>
                      <a href='".htmlentities($url)."'>
                <img src='slk/s-log.gif' alt='".htmlentities($name)."' border='0'></a>
                      <a href='".htmlentities($url)."'> <span class='menu'>$name</span></a></td>";
            }
        else{

            echo "<td width='".htmlentities($width)."%')>
                  <img src='slk/side-logo.gif'>
                  <span class='menu'> $name</span> </td>";

        }
     }

     public function DysplayFooter(){

        ?>
            <table width="100%" bgcolor="black" cellpadding="12" border="0">
                <tr>
                    <td>
                        <p class="foot"> © TLA Consulting Pty Ltd. </p>
