PHP Combine multiple arrays of objects and change array structure - php

Question

I have multiple separate arrays of objects that are imported (JSON-encoded) from MySQL that I need to merge and change structure. I basically need the combined [time] and [day] entries to be an array of [cycle] so I can loop over them. Currently after import/decoding the array of objects structure for each MySQL query looks like this:
(query 1)
stdClass Object
(
[day] => Array
(
[0] => stdClass Object
(
[day] => 1
[time] => 60
[name] => Running
[cycle] => 1
)
[1] => stdClass Object
(
[day] => 5
[time] => 30
[name] => Running
[cycle] => 1
)
)
[id] => 15359593
)
(query 2)
stdClass Object
(
[day] => Array
(
[0] => stdClass Object
(
[day] => 1
[time] => 55
[name] => Running
[cycle] => 2
)
[1] => stdClass Object
(
[day] => 5
[time] => 15
[name] => Running
[cycle] => 2
)
)
[id] => 36848901
)
The structure that need is:
stdClass Object
(
[day] => 1
[name] => Running
[cycle] => Array
(
[0] => stdClass Object
(
[time] => 60
[cycle] => 1
[day] => 1
)
[1] => stdClass Object
(
[time] => 55
[cycle] => 2
[day] => 1
)
)
[id] => 36848901
)
stdClass Object
(
[day] => 5
[name] => Running
[cycle] => Array
(
[0] => stdClass Object
(
[time] => 30
[cycle] => 1
[day] => 5
)
[1] => stdClass Object
(
[time] => 15
[cycle] => 2
[day] => 5
)
)
[id] => 1237465
)
I need the program to then iterate over the array using foreach [day] and then [cycle] to produce something like this:
name day cycle 1 cycle 2 cycle ..
Running 1 60 55 ..
Running 5 30 15 ..
..
It can only do it on a row by row basis. I don't have (much) control over this part of the process.
I have tried changing the structure by using foreach loops and array commands like this:
$newArray[] = array( "name" => $this->name, "day" => $this->day,
array("cycle" => $this->cycle, array("time" => $this->time, "cycle" =>
$this->cycle, "day" => $this->day)));
This gives me a structure that is almost right, per entry but not combined for all.
To combine them I've tried array_merge_recursive() and various variants but no luck.
So what I think I need is to merge the arrays of objects and then change the structure to have the values of each [time] and [day] to be nested inside the [cycle] so I can loop over them.
What is the best way to do this?
It is running on PHP 7.2.
More of my attempted code:
// get {data} part of JSON-encoded field for each mysql result
for ($x = 0; $x < $this->cycleCount; $x++) {
preg_match("/{.*}/",$this->tmpString[$x]['data'],$matches);
$this->data[$x] = json_decode($matches[0]);
foreach ($this->data[$x] as $day) {
$newArray[] = array( "name" => $day->name, "day" => $day->day,
array("cycle" => $day->cycle,
array("time" => $day->time,
"cycle" => $day->cycle,
"day" => $day->day)
)
);
}

Answer 1

$data = array();
$object = json_decode($querObject,true);
foreach($object as $day => $info)
{
foreach($info['cycle'] as $cycleInfo)
{
$data[$info['$id']]['name'] = $cycleInfo['name'];
$data[$info['$id']]['day'] = $cycleInfo['day'];
$data[$info['$id']]['id'] = $cycleInfo['id'];
$data[$info['$id']]['cycle'][] =array('time'=>$cycleInfo['time'],'cycle'=>$cycleInfo['cycle'],'day'=>=>$cycleInfo['day']);
}
}
