Get data from Json by php

Navigation
-1

People need to get data from a JSON file (I'm not the fuck in the business). This api below is for displaying temperature via JSON + PHP, remembering that on the same site I can not get the maximum, minimum or display days of the week, but this data is in JSON, but how do I display them? 

    <?php

    /*
     * Obtendo dados do HG Weather API
     *
     * Consulte nossa documentacao em http://hgbrasil.com/weather
     * Contato: [email protected]
     * Copyright 2015 - Hugo Demiglio - @hugodemiglio
     *
    */

    $cid = 'BRXX0198'; // CID da sua cidade, encontre a sua em http://hgbrasil.com/weather

    $dados = json_decode(file_get_contents('http://api.hgbrasil.com/weather/?cid='.$cid.'&format=json'), true); 
// Recebe os dados da API

    ?>

Below I'll leave it to you how I can display the other values. 

<?php echo $dados['results']['city_name']; ?>
<?php echo $dados['results']['temp']; ?>

More below you can see the JSON file formatted to understand better and also his link Online

If you want to catch the minimum and maximum of today do it! 

//para pegar as temperaturas use o objeto: $obj->results->forecast

$json = file_get_contents('http://api.hgbrasil.com/weather/?cid=BRXX0198&format=json');
$obj = json_decode($json);

foreach($obj->results->forecast as $k):
    if(date('d/m', mktime(0,0,0,date('m'), date('d'), date('Y'))) == $k->date):
        echo $k->date.' - '.$k->weekday.' - '.$k->min.' - '.$k->max;
    endif;
endforeach;

If you can turn this into an array you can use: array_search('value(dia)', $array) to search for the day you want

json_decode transforms json into a std_class object, that is, to retrieve the desired information use as follows: 

$dados->results->city_name;

Here's an example of Json in the sandbox.
