PHP implementation method of getting the most repeated elements in an array, php array

The example in this article describes the implementation method of PHP to obtain the most repeated elements in an array. Share it with everyone for your reference. The specific method is as follows:

Copy code The code is as follows:

/** 
 *  
 * 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 the repeated values ​​​​of the array
$array = array_count_values($array);
//2. Sort in reverse order based on duplicate values ​​
arsort($array);
If($length>0){
//3. Return the previous $length repeated 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 result is:
Array
(
[3] => 5
[4] => 3
[1] => 3
[9] => 2
[45] => 2
