I need a script that displays the tree structure of every category

P: n/a
I need your help. I'd be very thankfull if write me this script.I
need a script that displays a list of categories and subcategories
like this:

<select name="category">
<option value="1">Main</option>
<option value="2">Main > Computers</option>
<option value="4">Main > Computers > Hardware </option>
<option value="8">Main > Computers > Hardware > PC</option>
<option value="7">Main > Computers > Hardware > Mac</option>
<option value="9">Main > Computers > Hardware > Atari</option>
<option value="11">Main > Computers > Hardware > PC > History of
<option value="">etc...</option>
The categories and subcategories details are stored in these two
tables in a MySQL database.
-categories : the categories names and ids.
-cat_relations : the relations between categories.It shows which
subcategory belongs to which category.
The belongings between categories can go very deep and the number of
categories is unlimited. This script will create the two tables and
fill them with sample data. All you need to do is to change the four
variables below. You can send me the script back to this email :
ya****** and thank you in advance.

//Here starts the script. Please change the values of these variables
to fit your settings
$user = "db";
$database = "db";
$server = "localhost" ;
$pwd = "" ;
//Connection to the database that you created
mysql_connect($server,$user,$pwd) ;
//Creation of the two tables : categories and cat_relations
$categories = " CREATE TABLE `categories` (`id` INT not null
AUTO_INCREMENT, `name` VARCHAR(100) not null , PRIMARY KEY (`id`),
INDEX (`id`), UNIQUE (`id`)) comment = 'The categories details' ";
mysql_query($categories) ;
$cat_relations = "CREATE TABLE `cat_relations` (`id` INT not null
AUTO_INCREMENT, `daughter_id` INT not null, `mother_id` INT not null ,
PRIMARY KEY (`id`), INDEX (`id`), UNIQUE (`id`)) comment = 'Which
category is the daughter of which category'";
mysql_query($cat_relations) ;

//Filling the two tables with sample data
$cats = array('Main','Computers','Countries','Hardware','S oftware','Programming
languages','Mac','PC','Atari','Winamp','History of the
level','USA','NYC','LA','Manhattan','India','Winzi p');
for ($i=0;$i<count($cats);$i++){
$sql = mysql_query("insert into categories (name)
mysql_query("insert into cat_relations (daughter_id,mother_id) values
(2,1),(3,1),(4,2),(5,2),(6,2),(7,4),(8,4),(9,4),(1 1,8),(12,8),(13,8),(10,5),(20,5),(14,6),(15,3),(16 ,15),(17,15),(18,16),(19,3)");
//Now you can have a look on them through phpMyAdmin
