                                 udm_cat_path

   (PHP 4 >= 4.0.6)
   udm_cat_path -- Get the path to the current category.

Description

   array udm_cat_path ( resource agent, string category)

   Returns an array describing the path in the categories tree from the
   tree root to the current one, specified by category. agent is the
   agent identifier returned by a previous call to >udm_alloc_agent().

   The returned array consists of pairs. Elements with even index numbers
   contain the category paths, odd elements contain the corresponding
   category names.

   For example, the call $array=udm_cat_path($agent, '02031D'); may
   return the following array:
$array[0] will contain ''
 $array[1] will contain 'Root'
 $array[2] will contain '02'
 $array[3] will contain 'Sport'
 $array[4] will contain '0203'
 $array[5] will contain 'Auto'
 $array[4] will contain '02031D'
 $array[5] will contain 'Ferrari'

   Example 1. Specifying path to the current category in the following
   format: '> Root > Sport > Auto > Ferrari'
   <?php
     $cat_path_arr = udm_cat_path($udm_agent, $cat);
     $cat_path = '';
     for ($i=0; $i<count($cat_path_arr); $i+=2) {
       $path = $cat_path_arr[$i];
       $name = $cat_path_arr[$i+1];
       $cat_path .= " > <a
   href=\"$_SERVER[PHP_SELF]?cat=$path\">$name</a> ";
     }
   ?>
