Conditional based Wordpress functionality

Hey Experts!!

We have a Wordpress blog that has hundreds of different categories.  What I need to do is based on one specific category and it's child, I need to display an image.  I'll try to illustrate it to make it a little easier.

•      Category Main
   o      Subcat 1
   o      Subcat 2 <---I need to show the conditional on this subcat
   o      Subcat 3
   o      Subcat 4  

I did dump the category using the code below and the category ID, I'm seeking is in the 2nd part of the array.  I'm guessing because it's the 2nd category in line.

Any help is appreciated with points! :)



<?php
global $post;
$categories = get_the_category($post->ID);
var_dump($categories);
?>

you would add code to say

if($categories == "cat2")
  $showImage = true;



on the page that you want the image to display add check which page you are on. If you are on the page where you want to show the image display it. if not display nothing.

Still no joy.  

Here is the complete category dump results.  Maybe this will help
array(2){ 
[0]=> object(stdClass)#619 (15){ 
["term_id"]=> &string(4) "1883" 
["name"]=> &string(8) "Articles" 
["slug"]=> &string(8) "articles" 
["term_group"]=> string(1) "0" 
["term_taxonomy_id"]=> string(4) "1703" 
["taxonomy"]=> string(8) "category" 
["description"]=> &string(0) "" 
["parent"]=> &string(4) "1881" 
["count"]=> &string(2) "80" 
["cat_ID"]=> &string(4) "1883" 
["category_count"]=> &string(2) "80" 
["category_description"]=> &string(0) "" 
["cat_name"]=> &string(8) "Articles" 
["category_nicename"]=> &string(8) "articles" 
["category_parent"]=> &string(4) "1881" } 
[1]=> object(stdClass)#618 (15) { 

["term_id"]=> &string(4) "1116" 
["name"]=> &string(8) "MATCH THIS" 
["slug"]=> &string(8) "match-this" 
["term_group"]=> string(1) "0" 
["term_taxonomy_id"]=> string(3) "936" 
["taxonomy"]=> string(8) "category" 
["description"]=> &string(8) "match-this" 
["parent"]=> &string(4) "1115" 
["count"]=> &string(4) "2090" 
["cat_ID"]=> &string(4) "1116" <--NEED THIS ONE

This gives you an array:
$categories = get_the_category($post->ID);

You want to access the object in array position #1
$obj = $categories[1];

The assuming the property is public, you can do this:
$cat_id = (string)$obj->cat_ID;
echo $cat_id;

Got it.  

Final code is below:
<?php
			$category = get_the_category(); 
				echo $category[1]->cat_ID;
			?>

That works great for echo (echo does not care), but you might not want to depend on the data type being a string.  That is why I used explicit typecasting in my example.

Anyway, thanks for the points and good luck with the project, ~Ray

Thanks Ray.  I didn't think of that.  I'm going to be opening a new question in a moment regarding what I'm trying to do exactly.
