问题
I'm trying to count integer value from JSON: https://pomber.github.io/covid19/timeseries.json and got what I expected.
{
"date": [
"22 Jan",
"23 Jan",
"24 Jan",
"25 Jan",
....
],
"total_confirmed": [
555,
653,
941,
1434,
....
],
"total_deaths": [
17,
18,
26,
42,
....
],
"total_recovered": [
28,
30,
36,
39,
....
],
"max_value_of_total_confirmed": 272166
}
Here's my controller:
$client = new Client();$request = $client->get('https://pomber.github.io/covid19/timeseries.json');
$response = $request->getBody()->getContents();
$posts_dates = json_decode($response, true);
$confirmed_array = array();
$deaths_array = array();
$recovered_array = array();
if ( ! empty( $posts_dates ) ) {
foreach ( $posts_dates as $country => $data ) {
foreach ( $data as $dataKey => $dateData ) {
$date = new \DateTime( $dateData['date'] );
$day = $date->format( 'd M' );
if ( !isset($confirmed_array[$day]) ) {
$confirmed_array[$day] = 0;
}
$confirmed_array[$day] += $dateData['confirmed'];
}
foreach ( $data as $dataKey => $dateData ) {
$date = new \DateTime( $dateData['date'] );
$day = $date->format( 'd M' );
if ( !isset($deaths_array[$day]) ) {
$deaths_array[$day] = 0;
}
$deaths_array[$day] += $dateData['deaths'];
}
foreach ( $data as $dataKey => $dateData ) {
$date = new \DateTime( $dateData['date'] );
$day = $date->format( 'd M' );
if ( !isset($recovered_array[$day]) ) {
$recovered_array[$day] = 0;
}
$recovered_array[$day] += $dateData['recovered'];
}
}
}
$output = [
"date" => array_keys($confirmed_array),
"total_confirmed" => array_values($confirmed_array),
"total_deaths" => array_values($deaths_array),
"total_recovered" => array_values($recovered_array),
"max_value_of_total_confirmed" => max($confirmed_array)
];
return $output;
What I'm trying to get is grouping those data not by date, but by week of the month (W3 Jan, W4 Jan, W1 Feb, W2 Feb, etc). Any help would be appreciated :)
Thank you.

I would recommend using collection. You can easily manage using the methods provided by Laravel.
Group By Day
$client = new Client();
$request = $client->get('https://pomber.github.io/covid19/timeseries.json');
$response = $request->getBody()->getContents();
$posts_dates = json_decode($response, true);
/****** Here we go ******/
$posts_dates = collect($posts_dates)
->flatten(1)
->groupBy('date')
->map(function ($item, $key) {
$item = collect($item);
$date = \Carbon\Carbon::parse($key);
$key = 'W' . $date->weekOfMonth . $date->format(' M');
return [
'date' => $key,
'total_confirmed' => $item->sum('confirmed'),
'total_deaths' => $item->sum('deaths'),
'total_recovered' => $item->sum('recovered'),
];
})
->groupBy(function ($item, $key) {
return collect($item)->keys()->all();
})
->map(function ($item, $key) {
return $item->map(function ($item) use ($key) {
return $item[$key];
});
});
$posts_dates->put('max_value_of_total_confirmed', $posts_dates['total_confirmed']->max());
dd($posts_dates->toArray());
Result
