Merge 2 JSON Strings into one by different keys in PHP - php

Question

I am trying to combine 2 JSON objects from an API with 2 different id keys.
I have tried some code in php based on my working code in react native(javascript) but rebuilding the code did not work as expected.
sample first JSON:
[{
poiNumberWinter: null,
minAge: null,
maxAge: null,
minSize: 100,
maxSize: null,
minSizeEscort: 1,
id: 1,
titleImageId: 390,
titleImageWinterId: null,
createdAt: "2018-03-14T15:45:47.000Z",
updatedAt: "2019-03-26T10:58:44.000Z",
_titleWinter: null
}]
sample second JSON:
[{
open: false,
poiId: "1",
closing: null,
opening: "2019-08-15 10:00:00",
showTimes: null,
waitTime: null,
updatedAt: "2019-08-15T20:12:40.000Z",
}]
This is what I have tried:
$rideTimesconverted = json_decode($rideTimes);
$metaDataConverted = json_decode($metaData);
$fullRideData = array();
for ($i = 0; $i < count($rideTimesconverted); $i++) {
$test = array_filter($metaDataConverted, function ($item) use (
$i,
$rideTimesconverted
) {
return $item['id'] === (int) $rideTimesconverted[$i]['poiId'];
});
array_push($fullRideData, $rideTimesconverted[$i], $test);
}
based on my React Native code which works perfectly:
let rideTimes = await GetApiData.getRidesTime();
let rideMetaData = await GetApiData.getRidesMetaData();
let fullRideData = [];
for (let i = 0; i < this.state.rideTimes.length; i++) {
fullRideData.push({
...this.state.rideTimes[i],
...this.state.rideMetaData.find(
itmInner =>
itmInner.id ===
parseInt(this.state.rideTimes[i].poiId)
)
});
}
But the results get mixed up really weird:
{
open: false,
poiId: "1",
closing: null,
opening: "2019-08-15 10:00:00",
showTimes: null,
waitTime: null,
createdAt: "2019-08-15T22:18:03.000Z",
updatedRow: "2019-08-15T22:18:03.000Z"
},
[
{
poiNumberWinter: null,
minAge: null,
maxAge: null,
minSize: 100,
maxSize: null,
minSizeEscort: 1,
id: 1,
titleImageId: 390,
titleImageWinterId: null,
createdAt: "2018-03-14T15:45:47.000Z",
updatedAt: "2019-03-26T10:58:44.000Z",
_titleWinter: null
}
],
I want this result, merged on poiId and id being the same:
[{
open: false,
poiId: "1",
closing: null,
opening: "2019-08-15 10:00:00",
showTimes: null,
waitTime: null,
createdAt: "2019-08-15T22:18:03.000Z",
updatedRow: "2019-08-15T22:18:03.000Z"
poiNumberWinter: null,
minAge: null,
maxAge: null,
minSize: 100,
maxSize: null,
minSizeEscort: 1,
id: 1,
titleImageId: 390,
titleImageWinterId: null,
createdAt: "2018-03-14T15:45:47.000Z",
updatedAt: "2019-03-26T10:58:44.000Z",
_titleWinter: null
}]

This function should do the job if I read your question correctly.
$rideTimes = '[{
"poiNumberWinter": null,
"minAge": null,
"maxAge": null,
"minSize": 100,
"maxSize": null,
"minSizeEscort": 1,
"id": 1,
"titleImageId": 390,
"titleImageWinterId": null,
"createdAt": "2018-03-14T15:45:47.000Z",
"updatedAt": "2019-03-26T10:58:44.000Z",
"_titleWinter": null
},
{
"poiNumberWinter": null,
"minAge": null,
"maxAge": null,
"minSize": 100,
"maxSize": null,
"minSizeEscort": 1,
"id": 3,
"titleImageId": 390,
"titleImageWinterId": null,
"createdAt": "2018-03-14T15:45:47.000Z",
"updatedAt": "2019-03-26T10:58:44.000Z",
"_titleWinter": null
}]';
$metaData = '[{
"open": false,
"poiId": "1",
"closing": null,
"opening": "2019-08-15 10:00:00",
"showTimes": null,
"waitTime": null,
"updatedAt": "2019-08-15T20:12:40.000Z"
},
{
"open": false,
"poiId": "2",
"closing": null,
"opening": "2019-08-15 15:00:00",
"showTimes": null,
"waitTime": null,
"updatedAt": "2019-08-15T20:12:40.000Z"
}]';
function someFancyName($arrRideTime, $arrMetaData)
{
$hits = [];
foreach ($arrRideTime as $rTime) {
foreach ($arrMetaData as $mData) {
if ($mData['poiId'] == $rTime['id']) {
$hits[] = array_merge($rTime, $mData);
}
}
}
return $hits;
}
$arrRideTime = json_decode($rideTimes, true);
$arrMetaData = json_decode($metaData, true);
echo '<pre><code>';
var_dump(someFancyName($arrRideTime, $arrMetaData));
echo '</code></pre>';
