Laravel Chunk to show thousands records of data? - php

Question

I want to show almost a hundred records from the database. But the process very slow. So I try to add a chunk in the blade
Here is my controller
$user= User::where('status', '>=', '2')->get();
Here is my view.blade.php
#foreach($user->chunk(100) as $chunk)
#foreach ($chunk as $data)
<tr>
<td>{{$data->name}}</td>
<td>xxxx<td>
<tr>
#endforeach
#endforeach
But I didn't find the difference between before and after-use chunks. I know I can use data tables serverside/vajra/larawire. I also try with paginating but the searching/sort function not working coz I use data tables.
Since this website already lives. is there any short-term solution for that? because I have planning to implementation the serverside for the permanent fix but can do it asap.
if I chunk like this in the controller
$user= User::select('status','date','id','name','xxx')->where('status', '>=', '2')->orderBy('date_assign_fa','DESC')
->chunk(50, function($user) {
foreach ($users $user) {
**what i put in here if in im blade i also have foreach?**
}
});

As you pointed out that you are using relationship in this case:
You should be using eager loading:
$user = User::with('Detail')->where('status', '>=', '2')->get();
https://laravel.com/docs/8.x/eloquent-relationships#eager-loading
Also you can do something like this to receive speficic columns from relationship:
$user = User::with([
'Detail' => function ($query) {
$query->select('column1', 'column2');
}
])->where('status', '>=', '2')->get();
This could be single solution to all the performance issues
Old answer
As arrays are less heavy then collections one thing you could try is:
$usersArray = [];
User::select('status','date','id','name','xxx')
->where('status', '>=', '2')->orderBy('date_assign_fa','DESC')
->chunk(100, function($users) use ($usersArray) {
foreach ($users as $user) {
$usersArray[] = $user;
}
});
And then loop $usersArray in your view.
Also it could be simpler / faster to just use raw query:
$users = DB::select(
"SELECT
status, date, id, name, xxx
FROM users
WHERE status >= 2
ORDER BY date_assign_fa DESC"
);
As this will return you array not collection and this should use less memory / processor
