PHP echo JSON nested array values - php

Question

I want to echo all expanded_url and urls. echo $name prints results . echo $value doesn't print anything because of nested array. How do I echo all values?
$json ='{ "results" : [ { "entities" :
[ { "urls" : [ { "expanded_url" : "http://www.google.com",
"url" : "http://t.co/WZnUf68j"
}, { "expanded_url" : "http://www.facebook.com",
"url" : "http://t.co/WZnUf68j"
}, { "expanded_url" : "http://www.twitter.com",
"url" : "http://t.co/WZnUf68j"
} ] } ],
"from_user" : "A-user-name",
"from_user_id" : 457304735,
"text" : "Ich R U #BoysNoize #SuperRola"
} ] }';
# $json_array = (array)(json_decode($json));
$data = json_decode($json,true);
foreach($data as $name => $value){
echo $name.'<br>';
echo $value; // NOT WORKING - HOW TO ECHO ALL VALUES
}

Answer 1

You can do that with
$data = json_decode($json,true);
foreach($data["results"][0]["entities"][0]["urls"] as $value){
echo $value['expanded_url']."\n";
echo $value['url']."\n";
}

Answer 2

Since it's a multidimensional array, you can loop through the various levels to reach where you want.
foreach($data['results'] as $item) {
foreach($item['entities'] as $urls) {
foreach($urls['urls'] as $element) {
echo "expanded_url: {$element['expanded_url']} \n";
echo "url: {$element['url']} \n";
}
}
}
Note: The reason I've done the various foreach loops is due to the fact that there may be different results or different entities, so it's better to loop, than to do foreach($data["results"][0]["entities"][0]["urls"] as $value)
