[Resolved] deleting an array element...?

[vaska]

I have this little "subscribe to thread" function and I need to have some means for deleting the user out of the subscription if they choose. What I believe would be ideal is for me to simply delete their ID from the subscription_array that I've created (which does some other little things too).

I don't believe I can do this with array_slice.

The best practice I can see is to basically use the subscription_string and do a str_replace, preg_replace or whatever to remove the ID.

The one issue with that though is if I had user 1 unsubscribing then the _replace functions would also effect any "1". Hmmm...

Is that right? Or, maybe I'm missing an array function that could do this little trick?

Thanks for any advice, v

Why wouldn't unset work?

It will work, but I wasn't familar with it.

This does the trick, but I have to unset the element then get the array back into a string for the database.

unset($arr["$user_id"]);
$subscribed = implode(" ",$arr);

Thanks very much!
