How to use offset & limit in laravel - php

Question

I am facing issue to fetch records using offset and limit.
Currently I have 73 records in my database
My body request look like below.
{
"email": "",
"name": "",
"role_id":"",
"pageNumber": 8,
"pageSize": 10
}
Here pageNumber 8 means 7 page because it starts from 0
and page size is 10 means want to show 10 records in page and expected output should be 3 records because there is 3 records between 70 to 80 as my total records is 73 and it should display 3 records.
But its displaying 10 records:
My Code:
$pram = $request->name;
$email= $request->email;
$roleId= $request->role_id;
$pageNumber= $request->pageNumber;
$pageSize= $request->pageSize;
$UserResultQuery = User::with('userBasicInfo','userFacility','roles');
if (!empty($pram)) {
$UserResultQuery->where(function ($query) use ($pram) {
$query->whereHas('userBasicInfo', function ($query1) use ($pram) {
$query1->where('first_name', 'like', '%' . $pram . '%');
$query1->orWhere('middle_name', 'like', '%' . $pram . '%');
$query1->orWhere('last_name', 'like', '%' . $pram . '%');
})->with(['userBasicInfo' => function ($query1) use ($pram) {
$query1->where('first_name', 'like', '%' . $pram . '%');
$query1->orWhere('middle_name', 'like', '%' . $pram . '%');
$query1->orWhere('last_name', 'like', '%' . $pram . '%');
}]);
});
}
if (!empty($roleId)) {
$UserResultQuery->where(function ($query) use ($roleId) {
$query->whereHas('userFacility', function ($query1) use ($roleId) {
$query1->where('role_id', $roleId);
})->with(['userFacility' => function ($query1) use ($roleId) {
$query1->where('role_id', $roleId);
}]);
});
}
if (!empty($email)) {
$UserResultQuery->where('email', 'like', '%' . $email . '%');
}
$results=$UserResultQuery->offset($pageNumber)->limit($pageSize)->get();
$results=$results->toArray(); // here using offset and limit
$totalRecords=count($allUsers);
return response(['status' => true, 'data' => $user_array,'totalRecords' => $totalRecords]);

Answer 1

Pass offset row amount to offset() not page number.
$offset = ($pageNumber - 1) * $pageSize;
$results=$UserResultQuery->offset($offset)->limit($pageSize)->get();
You can also use this forPage(int $page, int $perPage = 15) doc.
$results=$UserResultQuery->forPage($pageNumber, $pageSize)->get();
