How to Flatten a Multidimensional Array?

Closed 3 years ago.
I have an eloquent object with data from the model which I need to convert to an array and have all indexes from the relations at the same array depth.
I tried array_flatten(), map(), filter() and other PHP methods but couldn't get it working correctly.
How I get my relations:
$data = Person::whereIn('id', $this->id[0])->where('school_id', '=',
$this->school)->with(['personinfo'=>function ($query) {
$query->select(
'person_id',
'general_info',
);
}, 'trades'=>function ($query) {
$query->select('person_id', 'trade_id')->with('trades');
}, 'measurements'=>function ($query) {
$query->select(
'person_id',
'measuring_point_1',
'measuring_point_1_date',
);
}])->get();
return $data->toArray();
What results in the array below, this is as close as I could get using different methods.
This is the outcome of the return function:
array:3 [
1 => array:17 [
"school_id" => 6
"birth_date" => null
"sex_id" => 1
"phone_number" => 62452676867897
"mobile_number" => 62398356786787
"email" => "example#example.com"
"personinfo" => array:5 [
"person_id" => 21
"general_info" => null
"health_info" => null
]
"trades" => array:3 [
"person_id" => 21
"trade_id" => 2
"trades" => array:8 [
"school_id" => 2
"name" => "blablabla"
]
]
"measurements" => array:7 [
"person_id" => 21
"measuring_point_1" => null
"measuring_point_1_date" => null
]
]
];
I need the array to be like this:
array:3 [
1 => array:17 [
"school_id" => 6
"birth_date" => null
"sex_id" => 1
"phone_number" => 624176676867897
"mobile_number" => 649498356786787
"email" => "example#example.com"
"person_id" => 21
"general_info" => null
"health_info" => null
"person_id" => 21
"trade_id" => 2
"school_id" => 2
"name" => "blablabla"
"person_id" => 21
"measuring_point_1" => null
"measuring_point_1_date" => null
]
]
];
Basically, I need to convert the multidimensional array to a zero depth array.
Any help would be appreciated.

Answer 1

You can use custom of array flatten with merging the inner with array-merge as:
function arrayFlatten($array) {
$res = array();
foreach ($array as $k => $v) {
if (is_array($v)) $return = array_merge($res, array_flatten($v)); // add recursively
else $res[$k] = $v; // just add
}
return $res;
}
Now just return arrayFlatten($data->toArray());
Simple live example

How i made it work using dWinder's answer
$data = Person::whereIn('id', $this->id[0])->where('school_id', '=', $this->school)->with(['personinfo'=>function ($query) {
$query->select(
'person_id',
'general_info',
);
}, 'trades'=>function ($query) {
$query->select('person_id', 'trade_id')->with('trades');
}, 'measurements'=>function ($query) {
$query->select(
'person_id',
'measuring_point_1',
'measuring_point_1_date',
);
}])->get();
function array_flatten($array)
{
$return = array();
foreach ($array as $key => $value) {
if (is_array($value)) {
$return = array_merge($return, array_flatten($value));
} else {
$return[$key] = $value;
}
}
return $return;
}
foreach ($data as $value) {
$result[] = array_flatten($value->toArray());
}
return $result;
