The docs note that the keys are preserved. Thus: $orig_array = array("zero", "one", "one", "two"); /* $orig_array is now the following: $orig_array[0] = "zero"; $orig_array[1] = "one"; $orig_array[2] = "one"; $orig_array[3] = "two"; */ $new_array = array_unique($orig_array); /* $new_array is now the following: $new_array[0] = "zero"; $new_array[1] = "one"; $new_array[2] = ""; $new_array[3] = "two"; */ The key of $orig_array[2] was preserved. I've added some clarification to the docs. -Bop -- Brought to you from iBop the iMac, a MacOS, Win95, Win98, LinuxPPC machine, which is currently in MacOS land. Your bopping may vary.
