here is the simple solution, I have get the count of each duplicate and then remove the ones whose having a single count

<?php
// just replace your array here
$array = [1, 2, 3, 1, 2];
$output = [];
foreach ($array as $key => $value) {
    $output[$value] += 1;
}

$array = [];
foreach ($output as $key => $value) {
    if($value > 1)
    $array[] = $key;
}

echo '<pre>';
print_r($array);
?>
// output
Array
(
 [0] => 1
 [1] => 2
)
