}

ERROR: 'Array to string conversion'

If I use the :

$diff = array_diff(array_map('serialize',$request->product), array_map('serialize',$product));

Then it will return the following result:

 array(2) {
        ["name"]=>
        string(15) "s:6:"samsung";"
        ["slug"]=>
        string(25) "s:15:"product-samsung";"
      }

The results above are correct for what I need. But it shows "s:6: and "s:15: inside the result. Is there a way for these two to not appear. I just want to get the correct result eg name is samsung. Thank you.

If you want to check which fields were updated, you can use isDirsty method. For example, you want to check if the user has changed the email, send an email verification:

if ($user->isDirty('email'))
{
    // Do something
}

try this

$diff = array_diff(array_map('serialize', $request->product), array_map('serialize', $product));

$multidimensional_diff = array_map('unserialize', $diff);

print_r($multidimensional_diff);
