如何在我的数组中重复计算值？

Question

I have already try like this

<?php
echo '<pre>';
$arrayName = array(1,2,3,4,5,6,2,3,1 );
$arr= array_count_values(array_column($arrayName,'5'));
print_r($arr);
?>

I just want to counting of repeated value

Answer 1

Why are you using array_column if you only want to count repeated values you can do this

<?php 
  echo '<pre>';
  $arrayName = array(1,2,3,4,5,6,2,3,1 );
  $arr= array_count_values($arrayName);
  print_r($arr);
?>
