If you know nothing about Wordpress but know how to display everything stored in an php array (at least in my case) - please answer. I'll appreciate!

I've an PHP array that keeps lists of categories. But I have no idea how to display its contents.

This code:

$category = get_the_category(); 
echo $category;

Outputs:

Array

What I want to do is to display first item in the array.

I've also tried:

  1. echo $category[0]->cat_name

  2. echo $category[1]->cat_name

Where the cat_name was "cat_name", "Folio" (my custom post type name), "type", "types" and "my_folio_cat". Everything outputs nothing (even not "Array" text).

I'm registering taxonomy like that:

register_taxonomy("my_folio_cat", array("folio"), array("hierarchical" => true, "label" => "Type", "singular_label" => "Type", "rewrite" => true));

from what I recall of get_the_category, $category[0]->cat_name should do it. Try var_dump($category) to see the structure of the variable, and it would help to edit your post and add that info here. It's not just arrays here, just to note - some of this info is stored in a PHP object. –  JAL Dec 6 '10 at 16:57
    
You should use name instead of cat_name (which is deprecated, and only currently implemented for back-compat) –  TheDeadMedic Dec 6 '10 at 18:36

var_dump I do believe.

Note that var_dump() prints variables, whereas print_r() is intended to be a human readable representation of the variables –  Rafe Kettler Dec 6 '10 at 16:57
    
var_dump is cool if you have xdebug installed –  ish1301 Dec 6 '10 at 16:57
    
Oh I've only ever used var_dump but then again I may not be human. –  cfeduke Dec 6 '10 at 17:01
    
@Rafe Kettler I don't find var_dump to be unreadable. It only provides more detail than print_r. –  JAL Dec 6 '10 at 17:38

try var_dump($category); instead echo $category;

array access is echo $arrayname[0];

make var_dump($array) and you can see what is there.

print_r($array);

You can also take a look at var_dump() (not intended for reading) and var_export() (even less so).

If you'd like to print things nicely, you could iterate over the array:

foreach($array as $key => $value) {
    echo 'Key is '.$key.' for value '.$value.'<br />';
}
