Hi !
I'm searching a way to parse a json file with php and display the 'fcttext' value

...
	"period":0,
		"icon":"cloudy",
		"icon_url":"http://icons.wxug.com/i/c/k/cloudy.gif",
		"title":"mercredi",
--------->     "fcttext":"Nuageux. Maximales : 76 °F. Vents ENE et variables.",
		"fcttext_metric":"Nuageux. Maximales : 24 °C. Vents ENE et variables.",
		"pop":"20"
		}
...

(all the json output here :

http://api.wunderground.com/api/b99efd866a7db36a/forecast/lang:FR/q/FR/Castelnaudary.json

)

So i've this php code :

 $json_string = file_get_contents("http://api.wunderground.com/api/b99efd866a7db36a/forecast/lang:FR/q/FR/Castelnaudary.json");
 $parsed_json = json_decode($json_string);
 $location = $parsed_json->{'location'}->{'Castelnaudary'};
  
 $weather = utf8_decode ($parsed_json->{'forecast'}->{'forecastday'}->{'period'}->{'fcttext'});

But i've not the value of fcttext inside $weather !
I'm not familiar with json_decode function !

Thanks for your help

In the json you provide "forecastday" is a json array element, not an object, and the bit you're after is within "txt_forecast", not just "forecast". I'd imagine in the PHP output you'd need to deference the specific period element you want, so something like:

$parsed_json->{"forecast"}->{"txt_forecast"}->{"forecastday"}[0]->{"fcttext"}

Works fine now. Many thanks muddy_shoes.
