For finding duplicates count in array elements, I have coded to answer your question. Please find below program in PHP Language.


$array = array("one", "three", "two", "one", "one", "two", "three");

function parseArray($arr, $val2) {
    $count = 1;
    $finalArray = array();
    foreach ($arr as $ar) {

        if ($val2 == $ar) {
             ++$count;
        }
    }
    return $count;
}

function checkinArray($array, $val) {
    foreach ($array as $v) {
        if ($v == $val)
            return true;
    }
    return false;
}

$checkArray = array();
$finalArray = array();

foreach ($array as $k => $val) {
    $newArray = $array;

    unset($newArray[$k]);
    if (!checkinArray($checkArray, $val)) {
        $checkArray[] = $val;
        $finalArray[$val] = parseArray($newArray, $val);
    }
}

//print the values
foreach ($finalArray as $key => $val)
    echo "element $key occurs $val number of times" . PHP_EOL;
