If the array values match each other, shuffle again - PHP

I have a form , Users can go to 7 Enter numbers in different fields , And then use

shuffle($_POST);

Mixed numbers , Then compare them with the numbers originally entered , So the output is as follows ：

1 12 43 64 25 76 37 5

This is the code I'm using .

<?php error_reporting(0);if ($_SERVER['REQUEST_METHOD']== "POST") {$array = implode("",$_POST);shuffle($_POST);}?><div class="box"><?php echo $array[0]; ?> <?php echo $_POST[0]; ?></div><br><div class="box"><?php echo $array[1]; ?> <?php echo $_POST[1]; ?></div><br><div class="box"><?php echo $array[2]; ?> <?php echo $_POST[2]; ?></div><br><div class="box"><?php echo $array[3]; ?> <?php echo $_POST[3]; ?></div><br><div class="box"><?php echo $array[4]; ?> <?php echo $_POST[4]; ?></div><br><div class="box"><?php echo $array[5]; ?> <?php echo $_POST[5]; ?></div><br><div class="box"><?php echo $array[6]; ?> <?php echo $_POST[6]; ?></div><br>

How to check the value of two arrays , To make sure they don't match . If they do match , Then I want to use it again shuffle（）, Until there is no match . I might use if else Statement to run the code again , Until the numbers don't match , But I'm not sure how to deal with .

Reference plan

stay while Check in the loop array_intersect_assoc($array,$_POST);, Until an empty array is returned , Random broadcast ！

Use array_intersect_assoc()：

$array = $_POST;do {    shuffle($_POST);} while ((count(array_intersect_assoc($array, $_POST))) !=0);
