Boolean Island !

I was reading Hasin Bhai’s New book Object Oriented Programming with PHP5.In chapter 2 i got a nice example of OOP.Its a word counter.Its a nice tool actually and pretty little too.Here is that example.

<?
class WordCounter
{
const ASC=1;  //you need not use $ sign before Constants
const DESC=2;
private $words;
function __construct($filename)
{
$file_content = file_get_contents($filename);
$this->words =
(array_count_values(str_word_count(strtolower
($file_content),1)));
}
public function count($order)
{
if ($order==self::ASC)
asort($this->words);
else if($order==self::DESC)
arsort($this->words);
foreach ($this->words as $key=>$val)
echo $key .” = “. $val.”<br/>”;
}
}
?>

popup menus are very popular now a days.There are many software which helps us to create popup menus.Those software use a JavaScript file.But the main problem is its really tough to edit that JS file without that software.And one software doesn’t support another software’s files.So i was looking for some simple script which will helps me understand and what can i change when ever i want.Then i found a nice solution its based on CSS and javaScript.It is using visibility property.Here is an example.

<div id="MENU"
  style="position:relative; width:80px; text-align:center;
  background-color:#DC6000; color:#FFFFFF; cursor:hand"
    onmouseover="document.getElementById('ITEMS').style.visibility='visible'"
    onmouseout="document.getElementById('ITEMS').style.visibility='hidden'">
      Menu
</div>

<div id="ITEMS"
style="position:relative; visibility:hidden; width:80px; text-align:center;
background-color:#DEB887; color:#FFFFFF"
  onmouseover="this.style.visibility='visible'"
  onmouseout="this.style.visibility='hidden'">

  <div style="background-color:#DEB887"
    onmouseover="this.style.backgroundColor='#9D4602'"
    onmouseout="this.style.backgroundColor='#DEB887'"
    onclick="location='url'">
      Menu Item 1
  </div>
  <div style="background-color:#DEB887"
    onmouseover="this.style.backgroundColor='#9D4602'"
    onmouseout="this.style.backgroundColor='#DEB887'"
    onclick="location='url'">
      Menu Item 2
  </div>
  <div style="background-color:#DEB887"
    onmouseover="this.style.backgroundColor='#9D4602'"
    onmouseout="this.style.backgroundColor='#DEB887'"
    onclick="location='url'">
      Menu Item 3
  </div>

</div>

Just copy and paste the code inside a HTML file and watch :).
