Is there a way to optimize the mapping of users? - sql

Question

I've created a method to call this getUserIdsByAllBranches() and the return would be an array. If array is not empty, I'll be doing another process. But I have a problem here in mapping or getting all the users with all branches.
Here's the code:
/**
* Get all User Ids of Branch Permission User
* By All Branches
* #param Array
* #return Array
*/
public function getUserIdsByAllBranches($override = [])
{
if (count($override) !== 0) {
foreach($override as $property => $value) {
${$property} = $value;
}
} else {
$branchLength = App::make(BranchRepository::class)->get()->count();
}
$userIdsWithAllBranches = [];
$userIds = $this->getUserIds();
foreach($userIds as $userId) {
$identical = true;
$userBranchIds = array_values($this->get()
->where('user_id', $userId)
->pluck(['branch_id'])
->unique()
->toArray());
if(count($userBranchIds) === $branchLength) {
$initialPermissions = [];
foreach($userBranchIds as $index => $userBranchId) {
if(!$identical) {
continue;
}
$branchUserPermissions = $this->get()
->where('user_id', $userId)
->where('branch_id', $userBranchId)
->sortBy('permission_id')
->pluck(['permission_id']);
if($index === 0) {
$initialPermissions = $branchUserPermissions;
} else {
if($initialPermissions != $branchUserPermissions) {
$identical = false;
}
}
}
} else {
$identical = false;
}
if($identical) {
array_push($userIdsWithAllBranches, $userId);
}
}
return $userIdsWithAllBranches;
}
/**
* Get all User Ids of Branch Permission User
*
* #return Array
*/
public function getUserIds()
{
return array_values($this->get()
->sortBy('user_id')
->pluck(['user_id'])
->unique()
->toArray());
}
This method getUserIds(), will be returning all the user ids for branch permission user table.
Branch Permission User Table:
branch_id
permission_id
user_id
