$countValues = array_count_values($myArray);

echo $countValues[Ben];

try the array_count_values() function

<?php
$array = array(1, "hello", 1, "world", "hello");
print_r(array_count_values($array));
?>

output:

Array
(
    [1] => 2
    [hello] => 2
    [world] => 1
)

You can do this with array_keys and count.

$array = array("blue", "red", "green", "blue", "blue");
echo count(array_keys($array, "blue");

Output:
