I have an array such as the following:

$inventory = array(
     "Blue Lampshade (US)" => 15,
     "Blue Lampshade (JP)" => 18,
     "Cushion" => 7
);

And I want to be able to test if a string I have is contained in the array as an element, then do something, if not, then just keep executing. I have a foreach() loop I'm running through, and want to highlight an item if it is found, if not, then it still needs to do more processing. Thus, it needs to fail silently, when it does.

Pseudocode:
.......
foreach($k $v){
     $item = "Cushion";
     .........
     if $inventory[$item] exists{
          highlight item (i have this code already)
     }
     .........
     rest of code
     ........
}

Can I do that? if($inventory[$item]))? Or would this throw an error or warning on my output?

And, yes, I know that data should be stored in mysql, but it is not an option for this particular script.
