looping through multi dimension array - php

Question

I am parsing A JSON file in PHP using PHP Decode
$json= file_get_contents ("resultate.json");
$json = json_decode($json, true);
and then I am trying to loop through the results and display them
foreach($json as $zh){
$name = $zh[0]["VORLAGEN"][0]["JA_PROZENT"];
$JA = $zh[0]["VORLAGEN"][0]["VORLAGE_NAME"];
$kreis = $zh[0]["NAME"];
$kreis1 = $zh[22]["NAME"];
echo $name;
echo $JA;
echo $kreis;
echo $kreis1;
...}
but I receive only one element e.g. position 0 or position 22. I would like to receive all the results and display them in a list. Below you can see the array
Array
(
[GEBIETE] => Array
(
[0] => Array
(
[VORLAGEN] => Array
(
[0] => Array
(
[VORLAGE_NAME] => Kantonale Volksabstimmung über die Vorlage Steuergesetz (StG) (Änderung vom 1. April 2019; Steuervorlage 17)
[JA_STIMMEN_ABSOLUT] => 205
[STIMMBETEILIGUNG] => 28.11
[NEIN_STIMMEN_ABSOLUT] => 183
[VORLAGE_ID] => 2491
[JA_PROZENT] => 52.84
)
)
[NAME] => Aeugst a.A.
[WAHLKREIS] => 0
[BFS] => 1
)
[1] => Array
(
[VORLAGEN] => Array
(
[0] => Array

[STIMMBETEILIGUNG] => 26.15
[NEIN_STIMMEN_ABSOLUT] => 851
[VORLAGE_ID] => 2491
[JA_PROZENT] => 54.02
)
)
[NAME] => Affoltern a.A.
[WAHLKREIS] => 0
[BFS] => 2
)
[2] => Array
(

[JA_PROZENT] => 59.28
)
)
[NAME] => Bonstetten
[WAHLKREIS] => 0
[BFS] => 3
)
can you please tell me how to print all the elements of this array?

Answer 1

There is GEBIETE layer in your json, so change foreach($json as $zh) to foreach($json["GEBIETE"] as $zh) will works.

Answer 2

You can nest multiple foreach:
$root = $json['GEBIETE'];
foreach ($root as $elem) {
foreach ($elem as $key => $value) {
// VORLAGEN is an array of its own so if you want to print the keys you should foreach this value as well
if(is_array($value)) {
foreach ($value[0] as $k => $v) {
echo $k."\t".$v;
}
}
else {
echo $value;
}
}
}
