<?php

$dupes = []; // keep track of duplicates
foreach ($users as $user1) { // iterate over all items
    $dupeCount = 0; // because we iterate over the same array, we always find at least the item itself (1 dupe minimum)

    foreach ($users as $user2) { // check the array again
        if ($user1 === $user2) { // if they are exactly the same: http://php.net/manual/en/language.oop5.object-comparison.php
            $dupeCount++;
        }
        if ($dupeCount > 1) { // because we always find at least 1, push only when we find more than that
            array_push($dupes, $user1); // add it to the result
        }
    }
}

However for you comment

I just want to check if detect secret_code same in array give me true else false

which should be in your question to begin with.

collect($users)->unique(function ($item) {
    return $item['secret_code'];
});

What is collect..? says undefined

online Thomas Over a year ago

collect is a function that creates a collection from an array: laravel.com/docs/5.6/collections

Ross Over a year ago

Bdw I'm using 4.2 this does not work, hope you understand my question if $users[0]['secret_code'] exactly match with $users[1]['secret_code'] should return true else false

online Thomas Over a year ago

@Ross you using v4.2 is something you should mention before, this way you do too little effort and the person(s) trying to answer you have to do too much guesswork.
