PHP Implementation of Getting the Most Repeated Elements in an Array

In this paper, the example tells the implementation method of PHP to get the most repeated elements in the array. Share it for your reference. The specific methods are as follows:

<?php  

/**  

 *   

 * Created on 2014-4-1  

 * @param   array $array  

 * @param   int [optional] $length  

 * @return  array  

 */  

function mostRepeatedValues($array,$length=0){  

    if(emptyempty($array) or !is_array($array)){  

        return false;  

    }  

    //1.  Calculate duplicate values of arrays   

    $array = array_count_values($array);  

    //2.  Based on duplicate values   Reverse sort   

    arsort($array);  

    if($length>0){  

        //3.  Before returning  $length  Duplicate value   

        $array = array_slice($array, 0, $length, true);  

    }  

    return $array;  

}  

$array = array(1, 1, 1, 54, 3,4, 3,4, 3, 14, 3,4, 3,7,8,9,12,45,66,5,7,8,9,2,45);  

$counts=mostRepeatedValues($array,5);  

print_r($counts);  

/* The output is: 

Array  

(  

    [3] => 5  

    [4] => 3  

    [1] => 3  

    [9] => 2  

    [45] => 2  

)  

*/  

?>
