is this inheritance?

Hello,

I like to start a new project where I need to loop through several levels to create sub items (line a xml parser).

Now I'm looking for some information, I know that this kind of technique is often used in OOP but I forgot the name of this pattern (is this a pattern?). Maybe someone can tell how is this called?

You mean something with category hierarhy?

If yes, you want to have infinite number of sub items or a specific number of levels?

yes, I want to create a class for a dynamic folded menu

I use this technique :

First you have a table with id, path where path is the path to reach the item.

For example this should be a tree :

id -> 1 , path -> 0
(parent of 1:)
id -> 2, path ->0,1
(parent of 2
id-> 3, path 0,1,2

etc.

Then I use a function like this :

Code:

<?php
$ar = array();
while($record = mysql_fetch_array( $res ))
{
     $s="";
     foreach (explode(",",$record['path']) as $i)
     {
      $s.= "[$i]";
     }
     $s.= "[".$record[0]."]";
     $u = "\$ar".$s."[name]= 'whatever you want here';";
     eval($u);
}

function re($ar,$d=0)
{ 
 if ($ar[name]) {
  $v=array_shift($ar);
        if($v!="")
             echo $v;
}

foreach($ar as $i=>$v)
  re($v,($d+1));

?>

It is a difficult to understand code fragment, hope you can make it work

It seems that this is not the perfect day to remember....

I remember an XML parser class that used a simmilar model, I will try to search my libraries if it is saved somewhere

Harry Fuecks? I think he is too busy and I think as an author for sitepoint he has to join the sitepoint forums first...
