[RESOLVED] Comparing Array Values

[denzlite]

Ok. Now I know what I need to do. Instead of comparing I need to remove.

Let's say I have a list of IDs in an array - how do I remove those array values from a subsequent array/query before I start to do stuff with the query...

unset($array[id]);

I'm not entirely sure as I'm not clear on how the two array are structured, but it might simply be a case for [man]array_diff/man.

So I have an array of id values that I don't want to echo that I know are in the table... stored in a variable $id_array... let's say there's three...

When I go to query the table for all the id's how do I remove the id's from $id_array before printing my links?

               //query db.table for all id's
               //but first remove id's from $id_array....
		while ($login = mysql_fetch_array($logins_set)) {		
			echo '<option value=' . $login['id'] . ' > ' . $login['name'] .' </option>';

	}

I've tried using unset - and I think that would work if my query were already a complete array?... but I'm using a while loop... ?

Thanks much

        while ($login = mysql_fetch_array($logins_set)) {        

if( !(in_array($login['id'],$id_array)){         

  echo '<option value=' . $login['id'] . ' > ' . $login['name'] .' </option>';
}
        }

MANY THANKS!

I'm going home now. Spending that long on a problem... I don't know if I'm cut out for this 😉
