从 json 中的子行中删除方括号

Question

I am trying to display the following data on a website:-

"daily":[{"dt":1593864000,"sunrise":1593834201,"sunset":1593894929,"temp":{"day":18.47,"min":17.83,"max":18.71,"night":17.83,"eve":18.71,"morn":18.47},"feels_like":{"day":16,"night":13.09,"eve":16.54,"morn":16},"pressure":1006,"humidity":77,"dew_point":14.37,"wind_speed":5.51,"wind_deg":244,"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}],"clouds":90,"uvi":7.08}

I extract any of the entries except the ones in the weather section as the code I'm using thinks that the weather data is a separate array.

The section of code relevant to displaying the data is:-

<span class="min-temperature">&nbsp;Minimum Temperature&nbsp;<?php echo $data->daily[0]->clouds; ?>&deg;C</span><br>
  <span class="min-temperature">&nbsp;Pressure&nbsp;<?php echo $data->daily[0]->weather->id; ?></span>

The first line displays data fine but anything within the weather section fails to display anything.

I've seen solutions to remove all the square brackets but its only the brackets surrounding the weather section that is needed.

Thanks in advance

Answer 1

the code below json_decodes and echoes cloud and the weather array. 'hope it helps. please comment. thank you.

<?php 

$data=json_decode( '{"daily":{"dt":1593864000,"sunrise":1593834201,"sunset":1593894929,"temp":{"day":18.47,"min":17.83,"max":18.71,"night":17.83,"eve":18.71,"morn":18.47},"feels_like":{"day":16,"night":13.09,"eve":16.54,"morn":16},"pressure":1006,"humidity":77,"dew_point":14.37,"wind_speed":5.51,"wind_deg":244,"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}],"clouds":90,"uvi":7.08}}'); # define $data as a stdClass Object
echo $data->daily->clouds;
echo "\n";

# below, weather array is converted into a string
$wa=(array)$data->daily->weather[0];
foreach($wa as $key=> $val){
    echo $key."=".$val."; ";
}

?>

Output:

90
id=500; main=Rain; description=light rain; icon=10d;

You must use json_decode in this case to convert a json string to associative array.

$data = '{"daily":{"dt":1593864000,"sunrise":1593834201,"sunset":1593894929,"temp":{"day":18.47,"min":17.83,"max":18.71,"night":17.83,"eve":18.71,"morn":18.47},"feels_like":{"day":16,"night":13.09,"eve":16.54,"morn":16},"pressure":1006,"humidity":77,"dew_point":14.37,"wind_speed":5.51,"wind_deg":244,"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}],"clouds":90,"uvi":7.08}}';
$decode = json_decode($data,true);
echo '<pre>';
//print_r($decode);
echo $decode['daily']['clouds'].'<br>';
echo $decode['daily']['uvi'].'<br>';

echo $decode['daily']['weather'][0]['id'].'<br>';
echo $decode['daily']['weather'][0]['main'].'<br>';  //These three are from weather array. 
echo $decode['daily']['weather'][0]['description'].'<br>';
echo '<pre>';

Output

90
7.08
500
Rain
light rain

If you want to know how the array indexes works you can make use of print_r from the code just remove it from comments.
