Make associative array from array structure build with JSON and Simple XML - php

Question

I read an XML file and want to get the values from the output array. This is the code to write the array:
$xml = simplexml_load_file('http://www.xyz.be/meteo');
$json_string = json_encode($xml);
$result_array = json_decode($json_string, TRUE);
The output array has the following structure:
Array
(
[STATION] => Array
(
[0] => Array
(
[#attributes] => Array
(
[ID] => 6407
[NAME] => Kust
)
[DAY] => Array
(
[0] => Array
(
[#attributes] => Array
(
[ID] => 20161110
)
[TMAX] => 10
[WEATHER] => 11
[DD] => NW
[FF] => 25
)
[1] => Array
(
[#attributes] => Array
(
[ID] => 20161111
)
[TMAX] => 8
[WEATHER] => 2
[DD] => ZO
[FF] => 8
)
)
)
[1] => Array
(
[#attributes] => Array
(
[ID] => 6479
[NAME] => Kempen
)
[DAY] => Array
(
[0] => Array
(
[#attributes] => Array
(
[ID] => 20161110
)
[TMAX] => 9
[WEATHER] => 6
[DD] => ZW
[FF] => 11
)
[1] => Array
(
[#attributes] => Array
(
[ID] => 20161111
)
[TMAX] => 5
[WEATHER] => 3
[DD] => NO
[FF] => 6
)
)
)
[2] => Array
(
[#attributes] => Array
(
[ID] => 6476
[NAME] => Ardennen
)
[DAY] => Array
(
...
I reayly tried a lot of things but I don't find the right solution.
** Question **
How can I put it all together in an associative array like this:
Array (
[0] => Array
(
['STAT_INDEX '] => 0
['STAT_ID'] => 6407
['STAT_NAME'] => Kust
['DAY_INDEX'] => 0
['DAY_DATE'] => 20161110
['DAY_TMAX'] => 10
['DAY_WEATHER'] => 11
['DAY_DD '] => NW
['DAY_FF '] => 25
)
[1] => Array
(
['STAT_INDEX '] => 0
['STAT_ID'] => 6407
['STAT_NAME'] => Kust
['DAY_INDEX'] => 1
['DAY_DATE'] => 20161111
['DAY_TMAX'] => 8
['DAY_WEATHER'] => 2
['DAY_DD '] => ZO
['DAY_FF '] => 8
)
[2] => Array
(
['STAT_INDEX '] => 0
['STAT_ID'] => 6451
['STAT_NAME'] => Centrum
['DAY_INDEX'] => 0
['DAY_DATE'] => 20161110
['DAY_TMAX'] => 10
['DAY_WEATHER'] => 11
['DAY_DD '] => W
['DAY_FF '] => 16
)
....
)
I get a lot of errors (notices): Array to string conversion, Undefined offset: 0, Undefined offset: 1...
Does anyone know a solution?
Thanks in advance!

I think I found it.
Maybe not the best code but it works.
$data = array();
$i = 0;
foreach($result_array['STATION'] as $station) {
$dag = 1;
foreach($station['DAY'] as $day) {
$data[$i]['ID'] = $station['#attributes']['ID'];
$data[$i]['NAME'] = $station['#attributes']['NAME'];
$data[$i]['DATUM'] = $day['#attributes']['ID'];
$data[$i]['DAG'] = $dag;
$data[$i]['TMAX'] = $day['TMAX'];
$data[$i]['WEATHER'] = $day['WEATHER'];
$data[$i]['DD'] = $day['DD'];
$data[$i]['FF'] = $day['FF'];
$i += 1;
$dag += 1;
}
}
gives me the result:
Array
(
[0] => Array
(
[ID] => 6407
[NAME] => Kust
[DATUM] => 20161110
[DAG] => 1
[TMAX] => 10
[WEATHER] => 11
[DD] => NW
[FF] => 25
)
[1] => Array
(
[ID] => 6407
[NAME] => Kust
[DATUM] => 20161111
[DAG] => 2
[TMAX] => 8
[WEATHER] => 2
[DD] => ZO
[FF] => 8
)
[2] => Array
(
[ID] => 6451
