Query Count Monthly of this year - Laravel 5.8 - php

Question

Today is 9/25/2019
I'm trying to query my visitor with in this year of 2019 only.
Then, I want to know how many are on
1,2,3,4,5,6,7,8,9
I've tried
$raw = Visitor::query()
->whereYear('created_at', now()->year -1)
->get()
->pluck('created_at');
$data = [];
foreach ($raw as $i=>$date) {
$data[$i] = Carbon::parse($date)->format('m');
if( Carbon::parse($date)->format('m')[0] != 0 ){
$data[$i] = Carbon::parse($date)->format('m');
}else{
$data[$i] = str_replace('0','',Carbon::parse($date)->format('m'));
}
}
// dd($data);
$dataValues = array_count_values($data);
dd($dataValues);
I got
array:5 [▼
8 => 314
9 => 916
10 => 764
11 => 827
12 => 765
]
Why would I get anything in the future since this month is only September (9) ?
How can I correct it?
I was hoping to get something like this
array:9 [▼
0 => 314
1 => 916
2 => 764
3 => 827
4 => 165
5 => 225
6 => 565
7 => 65
8 => 1265
]
I would like to get an array-like above output.

Answer 1

There are a couple of things you might try.
Laravel automatically makes created_at into a Carbon object, so if you create your query like this:
$raw = Visitor
::whereYear('created_at', \Carbon::now()->year) <<-- Note 2019, not -1 for 2018
->select('created_at')
->get();
Here you get an object with the Carbon date field, created_at. You then won't need to use parse in your if-checks.
I suspect perhaps the answer to your question, though, is that it looks like you are pulling items from 2018, when you want 2019. You have subtracted a year off of this year in your original query.

Answer 2

you should extract month from date then groubby ,and don't forgot select count :
Visitor::whereYear('created_at', Carbon::now()->year)
->select(DB::raw("MONTH(created_at) month"),DB::raw("count('month') as vistors_count"))
->groupby('month')
->get();
