After a $single_array = array_reduce ($new_array, 'array_merge_recursive', array ());
I get this result
array (size=9)
'key1' => string 'value1'
'key2' => string 'value2'
'key3' => string 'value3'
'key7' =>
array
0 => string 'value7'
1 => string 'value13'
'key8' =>
array
0 => string 'value8'
1 => string 'value14'
'key9' =>
array
0 => string 'value9'
1 => string 'value15'
'key19' => string 'value19'
'key20' => string 'value20'
'key21' => string 'value21'
but i would like that
array
'key1' =>
array
0 => string 'value1'
'key2' =>
array
0 => string 'value2'
'key3' =>
array
0 => string 'value3'
'key7' =>
array
0 => string 'value7'
1 => string 'value13'
'key8' =>
array
0 => string 'value8'
1 => string 'value14'
'key9' =>
array
0 => string 'value9'
1 => string 'value15'
'key19' =>
array
0 => string 'value19'
'key20' =>
array
0 => string 'value20'
'key21' =>
array
0 => string 'value21'
It's probably very simple, but I've been blocking for a few hours.
In short, I would like my array_merge_recursive not to add a key only to the same values, but to add an array[0] also to those which were not the same.
EDIT
The code at the start, the goal being to simplify it and knowing that the values generated as well as the order of the structure can be random.
<?php
$array = array(
'sensors' => array(
'0' => array(
'data' => array(
'0' => array(
'key1' => 'value1',
'key2' => 'value2',
'key3' => 'value3',
)
)
),
'1' => array(
'data' => array(
'0' => array(
'key7' => 'value7',
'key8' => 'value8',
'key9' => 'value9',
)
)
),
'2' => array(
'data' => array(
'0' => array(
'key7' => 'value13',
'key8' => 'value14',
'key9' => 'value15',
)
)
),
'3' => array(
'data' => array(
'0' => array(
'key19' => 'value19',
'key20' => 'value20',
'key21' => 'value21',
)
)
)
)
);
$new_array = array();
foreach ($array as $element1) {
foreach ($element1 as $j => $element2) {
foreach ($element2 as $element3) {
foreach ($element3 as $element4) {
$new_array[$j] = $element4;
$single_array = array_reduce($new_array, 'array_merge_recursive', array());
}
}
}
}
var_dump($single_array);

You can use array_walk_recursive
on the original array:
$result = [];
array_walk_recursive($array, function ($value, $key) use (&$result) {
$result[$key][] = $value;
});
After running this on the example array you provided, $result
will be:
[
'key1' => ['value1'],
'key2' => ['value2'],
'key3' => ['value3'],
'key7' => ['value7', 'value13'],
'key8' => ['value8', 'value14'],
'key9' => ['value9', 'value15'],
'key19' => ['value19'],
'key20' => ['value20'],
'key21' => ['value21']
];

Thank you, I found, I was just confusing in_array and is_array. My bad
$array2 = array();
foreach ($single_array as $key1 => $value1) {
if (is_array($value1)) {
foreach($value1 as $key2 => $value2) {
$array2[$key1][$key2] = $value2;
}
}
else {
$array2[$key1][] = $value1;
}
}
var_dump($array2);
