Re: Unique Array

and more practically your code get corrected to this: for ($i = 0; $i<100; $i++) { $a[$i] = rand(0,9); $test[]=$a[$i]; } $ra = array_unique($test); and your code get optimized to this: (mostly of the manual!;)) $numbers = range (0,9); srand ((double)microtime()*1000000); shuffle ($numbers); "Cc Zona" <cczona@nospam.invalid> wrote in message news:20010910114509.77443.qmail@pb1.pair.com... > In article <F135FwtuYS6VnL9wtlo0000a9f7@hotmail.com>, > mccanndee@hotmail.com (Deirdre Mc Cann) wrote: > > > for ($i = 0; $i<100; $i++){ > > $a[$i] = rand(0,9); > > $test=$a[$i]; > > } > > > > $ra = array_unique($test); > > > > I keep getting an error saying $test is the incorrect type.
