Loop trough and modify JSON response - php

Question

I am making API request to Google Sheets and I receive this response:
Array
(
[0] => Array
(
[Title] => Hours
[January] => 1
[February] => 2
[March] => 3
[April] => 4
[May] => 5
[June] => 6
[July] => 7
[August] => 8
)
[1] => Array
(
[Title] => Days
[January] => 3
[February] => 5
[March] => 1
[April] => 6
[May] => 3
[June] => 7
[July] => 4
[August] => 2
)
[2] => Array
(
[Title] => Weeks
[January] => 3
[February] => 5
[March] => 3
[April] => 4
[May] => 0
[June] => 0
[July] => 2
[August] => 6
[September] => 0
[October] => 0
[November] => 1
[December] => 0
)
)
How could I loop trough and modify this array to something like this so I can use it with HighCharts JS library?
series: [{
title: 'Hours',
data: [1, 2, 3, 4, 5, 6 .......]
}, {
title: 'Days',
data: [4, 6, 3, 6, ........]
}, {
title: 'Weeks',
data: [1, 9, 1, 3, ........]
}, {
....
}]
I tried this way:
if ($response->status) {
$rawData = json_decode(json_encode($response->data), true);
}
$series = [];
foreach ($rawData as $index => $rawDatum) {
if (!isset($rawDatum['Title'])) {
continue;
}
foreach ($rawDatum as $columnKey => $value) {
if ($columnKey == 'CvA') {
$series[$columnKey]['Title'][] = $value;
}
}
}
What I got as result:
Array
(
[Title] => Array
(
[title] => Array
(
[0] => Hours
[1] => Days
[2] => Weeks
)
)
)
Also is there a way to get all names of the months saved in $months array for example without doubles?

Answer 1

The following piece of code will create an array with title and the values for each respective subarray Hours, Days, Weeks.
We will also collect the union of the months in an array named $months.
$series = [];
$months = [];
foreach ($rawData as $subarray) {
$title = $subarray['Title'];
// Remove title key
unset($subarray['Title']);
$series[] = [
'title' => $title,
'data' => array_values($subarray),
];
// Union operator to keep unique months.
$months += array_keys($subarray);
}
echo '<pre>';
print_r($months);
echo '</pre>';
echo '<pre>';
print_r($result);
echo '</pre>';
Result $months:
Array
(
[0] => January
[1] => February
[2] => March
[3] => April
[4] => May
[5] => June
[6] => July
[7] => August
[8] => September
[9] => October
[10] => November
[11] => December
)
Result $series:
Array
(
[0] => Array
(
[title] => Hours
[data] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
)
)
[1] => Array
(
[title] => Days
[data] => Array
(
[0] => 3
[1] => 5
[2] => 1
[3] => 6
[4] => 3
[5] => 7
[6] => 4
[7] => 2
)
)
[2] => Array
(
[title] => Weeks
[data] => Array
(
[0] => 3
[1] => 5
[2] => 3
[3] => 4
[4] => 0
[5] => 0
[6] => 2
[7] => 6
[8] => 0
[9] => 0
[10] => 1
[11] => 0
)
)
)

Answer 2

Given this data:
$data = [
[
'Title' => 'Hours',
'January' => 1,
'February' => 2,
'March' => 3,
'April' => 4,
'May' => 5,
'June' => 6,
'July' => 7,
'August' => 8,
],
[
'Title' => 'Days',
'January' => 3,
'February' => 5,
'March' => 1,
'April' => 6,
'May' => 3,
'June' => 7,
'July' => 4,
'August' => 2,
],
[
'Title' => 'Weeks',
'January' => 3,
'February' => 5,
'March' => 3,
'April' => 4,
'May' => 0,
'June' => 0,
'July' => 2,
'August' => 6,
'September' => 0,
'October' => 0,
'November' => 1,
'December' => 0,
]
];
You should be able to do this:
// Store everything here
$result = [];
foreach ($data as $item) {
// Grab the title
$ret['title'] = $item['Title'];
// Remove it from the source dataset
unset($item['Title']);
// Take the remaining values, join with comma
$ret['data'] = implode(',', array_values($item));
// Append to main array
$result[] = $ret;
}
You can skip the implode if want an actual array
