Multi level categories

[sami]

Hi,

I cannot seem to find any articles about multi level categories and sub categories in php.

I only know how to create a 1 level categories only. Does anyone know how or could point me into the right direction?
thanks in advance.

Categories of what?

A filesystem setup will work, as will a tree setup with a database, where you have a table of "folders," each of which except the root has exactly one parent referenced.

I meant like using mkdir() to make a dir and add subdir into it.

I think it is something like this:

Top Level
- Sub1
- Sub1_1
- Sub1_2
- Sub2
- Sub3

mkdir('dir/subdir');

I'm learning how to explain this.

Just say that I a top level category or directory and I wanted to create very very deep into that category.

Like this...

Top Level > x > xx> and etc... nn>vv

So how would you create that from a php script. thanks.

I'm so confused about even the general idea of what you are doing.

you're making folders on the site, right?

So... mkdir('a/b/c/d/e/.../z/whatever'); ?

With PHP5, you can:

mkdir('x/xx/blah/nn/vv', 0777, true);

However, in earlier versions you'd have to do it one at a time:

$pathname = 'x/xx/blah/nn/vv';
$dirs = explode('/', $pathname);
foreach($dirs as $i => $dir)
  mkdir(implode('/', array_slice($dirs, 0, $i + 1)));

Oh, I didn't think of that. I was just accessing the folder, forgetting that I was creating it as that function. How silly.
