Solution:

You must usejson_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>';
Copy code

Output

90
7.08

light rain

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