Array problem

[Skudd]

I am using a multi-dimensional array to hold various things for a small CMS I am writing. Here is an example of my array:

$foo['config']['time_zone'] = '-6';
$foo['config']['admin_email'] = '[e-mail]';

I need to be able to retrieve the names of the items under the config level, which I will later use to retrieve the values. Is there any way to do this. The less lines of code the better.

Thanks in advance!

$names_of_items = array_keys ($foo['config']);

foreach ($names_of_items as $key => $value) {

print ($value);

}

Warning: First argument to array_keys() should be an array in /var/www/html/cms/index.php on line 19

Warning: Invalid argument supplied for foreach() in /var/www/html/cms/index.php on line 21

Edit:
I tried that with my actual code and it didn't work, but with the code I posted here, which is virtually identical, it threw the error above. 😕

I am an idiot. I forgot to include the file containing the variables. Thanks for the help! 😃
