Does anyone know an efficient way to take out duplicate values in an array? I have a web page that queries a dtabase and get a long list of keywords to display in a . I don't want any duplicates, so maybe someone can help me out?

Try using a modified bubble sort (plenty of examples in this forum recently). Instead of doing the if n[j]]n[j+1]then swap
replace with if n[j]=n[j+1] then do nothing else n[j]=n[j+1]
You might have to fiddle with it a bit, but it should work (good idea to sort then too) regards, Elric

G'day,
I'm sorry about that: greater than doesn't work, so I use square bracket instead- now that doesn't work --- any ideas???????????
that first line should have read:
if n[j] is greater than n[j+1] then swap
those square brackets worked but the gtr than square bracket didn't??????????? hope I haven't confused you too much... regards, Elric

Why not clean the process at the beginning of the task? When you query the database, just use the DISTINCT keyword in your query (i.e., SELECT DISTINCT(LastName) FROM Employees). Then you will only get one occurrence of each returned value. Make sense?
