/* SORRY ignore my previous post, this code is updated */
// an easiest way to get unique AND duplicated items...
$unique=array("","A1","","A2","","A1","");
$duplicated=array();
foreach($unique as $k=>$v) {
if( ($kt=array_search($v,$unique))!==false and $k!=$kt )
{ unset($unique[$kt]); $duplicated[]=$v; }
}
var_export($unique);
var_export($duplicated);
// will output
array ( 3 => 'A2', 5 => 'A1', 6 => '', )
array ( 0 => '', 1 => '', 2 => 'A1', 3 => '', )
/* SORRY =P */
