this code works fine

<?php

$arr1 = array(0=>5,1=>7, 2=>9, 3=>4, 4=>2, 5=>8, 6=>7, 7=>0, 8=>1);
$arr2 = array(0=>7,1=>2, 2=>4, 3=>5, 4=>9, 5=>8, 6=>5, 7=>0, 8=>6);

$arr = array_intersect_assoc($arr1, $arr2);
print_r($arr);

$duplicate=array(); $duplicateVirtual=[];

foreach($arr2 as $index=>$val)
{   
    if(in_array($val,$duplicateVirtual)){ $duplicate[$index]=$val; }
    $duplicateVirtual[]=$val;
}

print_r($duplicate);

You can even create a function to check for duplicate and pass array as variable.

You are looking for array_intersect_assoc()

$arr1 = array(0=>5,1=>7, 2=>9, 3=>4, 4=>2, 5=>8, 6=>7, 7=>0, 8=>1);
$arr2 = array(0=>7,1=>2, 2=>4, 3=>5, 4=>9, 5=>8, 6=>5, 7=>0, 8=>6);

$arr = array_intersect_assoc($arr1, $arr2);
