Have a look at the array_count_values() function.

Example:

$arr = array(2, 2, 2, 2, 2, 3, 4, 2, 1, 2, 5, 5, 68);

foreach(array_count_values($arr) as $value => $count)
{
    printf("%d x %d<br />\n", $count, $value);
}

Answer is array_count_values

$array = array(2, 2, 2, 2, 2, 3, 4, 2, 1, 2, 5, 5, 68);
print_r(array_count_values($array))

Check out the documentation

Output

Array
(
    [2] => 6
    [3] => 1
    [4] => 1
    [5] => 2
    [68] => 1
)
