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

    <?php

    */

    $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 how I can display the other values.

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

Below you can see the formatted JSON file to better understand and also its link Online

php json api

  • I do not understand very well what you want. You want to display in your php the day of the week, min temp and max?

  • Exact would like to take the minimum, maximum and the day of the week. I don’t know much of JSON, like tried in the following ways. &#xA;<?php echo $dados['results']['max']; ?>&#xA;<?php echo $dados['results']['forecast']['max']; ?>&#xA;<?php echo $dados['forecast']['max']; ?>&#xA;

    No json { means object and [ array, then to access this information you will have to go through the forecast array. Example: <?php echo $dados['results']['forecast'][0]['max']; ?> <?php echo $dados['results']['forecast'][0]['min']; ?> <?php echo $dados['results']['forecast'][0]['weekday']; ?>

  • I did a test going through the array and really returned me the data of it very straight ! Thank you so helped a lot.

If you want to get the minimum and maximum today do this! 

//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 transform this into an array you can use: array_search('value(dia)', $array) to find the day you want

  • Correct, that way also returned me the data correctly, if I do the @Jessika way will also work, I am grateful to have also helped.

  • If I helped, upvote :D, now that you have the notion of how to go through the loop, you can create your own codes.

  • Since I have the current day data running through the array, is there a way I can display the data for the next 3 days ? Today is Thursday Here I display the data of the day, temp, max, ?

    On parole if(date('d/m'....) you realize that there is a function date('d') she’s inside the mktime(), just insert two more if's thus: if(date('d/m'), mktime(0,0,0,date('m), date('d) + 1), date('Y)) //essa condicional pega o dia de amanhã if(date(), mktime(0,0,0,date('m), date('d) + 2), date('Y)) //essa condicional pega o dia depois de amanha, observe the date('d')+1 //significa dia de hoje mais 1 and the other is worth the same.

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

$dados->results->city_name;

Follows here an example of Json in sandbox.
