Sort array based on duplicate values

I have an array which contains duplicate values. I want to sort the array so that the values with the most duplicates appear first in line.

I want an output like:

Rihanna
U2
Becca
Taylor Swift

My file that contains data:

rihanna
rihanna
rihanna
rihanna
taylor swift
becca
becca
u2
u2
u2

My code as is which wont work:

$input = file_get_contents('files');
$input = explode("\n", $input);

$acv = array_count_values($input);
$acv = arsort($acv); 
$result = array_keys($acv);
print_r($acv); //Outputs Blank

Here is your solution your array is :

$arr = array('rihanna','rihanna','rihanna','rihanna','taylor swift','becca','becca','u2','u2','u2');

$acv = array_count_values($input);
// If need to remove element with count = 1

foreach($acv as $key => $value)
{
    echo $value;
    if($value == 1)
    {
        unset($nArr[$key]);
    }
}
//End
$fArr = array_flip($acv);

krsort($fArr);
print_r(array_values($fArr));

//output
Array
(
    [0] => rihanna
    [1] => u2
    [2] => becca
    [3] => taylor swift
)
