dthable's Journal: [PHP] Working with Arrays

I've been working on this application that requires adding a key value pair to an existing dictionary. The quick solution I found was:

$one = array( 1 => "one", 2 => "two");
$two = array( 3 => "three", 4 => "four");
$new = array_merge( $one, $two);

Is there some way to just append without the merge? While array_merge works in this case, what if I just want to append a single item? Also, is there an OO implementation of an array? I'd like to be able to say $new->sort() instead of using a function.

what if

you just did something like:

if (! array_key_exists("key",$array)) {
    array_push($new_key_value,$array);
}

have i overlooked something?

That's what I've ended up doing, but it just doesn't sit well with me. It' doesn't seem like a natural operation, plus I haven't found a method to insert into the middle of an array.
