如何用子类别循环子类别？

Question

EDIT: ok let me be a bit more clear i have a html file name file.html it is like this:

{category} {sybcategory}

and i have a index file which is like this:

class template { var $page;

function add_file($file){
    $this->page = file_get_contents($file);
    return $this->page;
}

function vars($array)
{
    foreach($array as $key => $value)
    {
        $this->page = str_replace('{'.$key.'}', $value, $this->page);
    }
    echo $this->page;
}

}

$template = new template();

$template->add_file('file.html');

$template->file_vars(array('category' => $row_cat['title'], 'subcategory' => $row_subcat['title']));

now, this only outputs the title and the subcategory only once how do i loop that and i have not added the mysql query here because i don't wanna waste your more time please if you know how to do it then let me know.

Answer 1

How about storing everything within those whiles you have there?

while (mysql_fetch_assoc($mycategory)){

  $catsArray[] = $cat_title;

  while (mysql_fetch_assoc($mysubcategory)){

   $catsArray[] = $subcat_title;

  } 
}

This way you'll have a single array with all the cats followed by their subcats.

Hope it helps a bit :)

EDIT: I think I misunderstood your question, what I answered covers how you can group them, but what you're asking in the end is a template engine such as Smarty, which can't be "summarized" in a single answer here in Stackoverflow, you'd need to build the engine before you can use something like {catArray}.

Answer 2

Here you go:

$cats = array();

while (mysql_fetch_assoc($mycategory))
{    
    $cats[$cat_title] = array();

    while (mysql_fetch_assoc($mysubcategory))
    {
        $cats[$cat_title][]  $subcat_title;
    }
}

This will give you an array of arrays. The first array contains the category titles as keys and they will contain an array of all the sub category titles.
