Comparing associative arrays inside foreach loop laravel PHP

Question

Using eloquent, I am querying two sets of data like so:

$all_perms = Permission::all(); //all permissions
$role_perms = Auth::user()->roles()->permissions; //permissions belonging to a role

$role_perms is a subset of $all_perms and what I want is to loop both arrays and come out with a new array containing all permissions already assigned to a role together with those not yet assigned to a role.

What I have done is loop through both arrays in a foreach loop and if any one array belongs to both sets, I mark it by adding a check key with corresponding value 1 to the array so that I can identify is as a permission already assigned to a role.

foreach ($role_perms as $role_perm) {
    foreach ($all_perms as $key => $value ) {
        if (array_diff_assoc($all_perm, $role_perm)) {
            $all_perm['check'] = 1; 
        }
    }
}

but it keeps throwing the error:

array_diff_assoc(): Argument #1 is not an array

Are they better ways of doing this? Or what can I do on this one to make it work?

Thanks for any help

That's because it's a collection, not an array. If you want to get an array, try to use toArray():

$all_perms = Permission::all()->toArray();

Also, is this a typo here:

array_diff_assoc($all_perm, $role_perm);

It should be $all_perms

Try using the wonderful contains method that is available on all your collections:

foreach ($role_perms as $role_perm) {
   if($all_perms->contains($role_perm))
   {
      // do whatever is needed
   }
}

Checkout the docs for help with the contains method.
