Loop JSON String response in PHP Foreach - php

Question

I'm trying to print values of a JSON response in PHP. Inside the contents are:
data
local
acao
detalhes
Codes:
<?php
header('Content-type: text/html; charset=UTF-8');
$url = "http://developers.agenciaideias.com.br/correios/rastreamento/json/RJ290474594CN";
$c_url = file_get_contents($url);
$c_url = utf8_encode($c_url);
$results = json_decode($c_url);
echo $c_url;
?>
I've tried using foreach but wasn't successful in implementing them in said JSON response.
Here is a JSON String Example:
[{"data":"07\/12\/2014 11:19","local":"CHINA - CHINA\/CN","acao":"postado","detalhes":"-"},{"data":"09\/12\/2014 12:03","local":"CHINA - CHINA\/CN","acao":"encaminhado","detalhes":"Em tr\u00e2nsito para Unidade de Tratamento Internacional - BRASIL\/BR"},{"data":"29\/12\/2014 12:34","local":"UNIDADE TRAT INTERNACIONAL PARANA - Curitiba\/PR","acao":"conferido","detalhes":"Recebido\/Brasil "}]

If you just want to print values just print them accordingly using foreach. After getting the response, use json_decode(). That ut8f_encode() is superfluous.
$url = "http://developers.agenciaideias.com.br/correios/rastreamento/json/RJ290474594CN";
$data = json_decode(file_get_contents($url), true);
foreach($data as $values) {
echo $values['data'] . '<br/>';
echo $values['local'] . '<br/>';
echo $values['acao'] . '<br/>';
echo $values['detalhes'] . '<br/>';
}
Sample Output
Or:
$url = "http://developers.agenciaideias.com.br/correios/rastreamento/json/RJ290474594CN";
$data = json_decode(file_get_contents($url), true);
foreach($data as $values) {
foreach($values as $key => $value) {
echo "{$key}: $value <br/>";
}
echo '<hr/>';
}
