I am baffled by your selection as the accepted answer -- I can't imagine how it can possibly satisfy your requirements.

array_count_values() has been available since PHP4, so that is the hero to call upon here.

Code: (Demo)

$array = array("kani","yuvi","raja","kani","mahi","yuvi") ;

$counts = array_count_values($array);  // since php4
foreach ($counts as $value => $count) {
    if ($count == 1) {
        $uniques[] = $value;
    } else {
        $duplicates[] = $value;
    }
}

echo "unique values: " , implode(", ", $uniques) , "\n";
echo "duplicate values: " , implode(", ", $duplicates);

Output:

unique values: raja, mahi
duplicate values: kani, yuvi
