| Extraer datos de json con PHP
Necesito extraer de un json que tiene la siguiente estructura, period 0, period 1 los nombres de icon y luego de day 14 las conditions,
Como podria hacerlo tengo el siguiente php, pero no lo consigo, estoy probando con icon.
$json_string = file_get_contents("http://.json");
$parsed_json = json_decode($json_string);
$temp_c = $parsed_json->{'forecast'}->{'forecastday'}->{'icon'};
?>
<?php
echo $temp_c;
?>
//JSON
