JSON decode toarray

Yii 1.1 General Discussion

When i use JSON::decode,it decodes to a string.How can i convert that to an array?

2

What is the string that you are passing to it?

3

my json file type:


{"AC":"Ascension Island","AD":"Andorra","AE":"United Arab Emirates","AF":"Afghanistan"....

Well i have tested that code




public function actionTest(){

	

		$cars=array("Saab","Volvo","BMW","Toyota");


		echo '<pre>';

		echo "Car:<br/>";

		print_r($cars);

		echo '</pre>';

		

		$encode=CJSON::encode($cars);

		

		echo $encode;

		

		$decode=CJSON::decode($encode);

		echo '<pre>';

		print_r($decode);

		echo '</pre>';

	}

And it generate This output




Car:

Array

(

    [0] => Saab

    [1] => Volvo

    [2] => BMW

    [3] => Toyota

)


["Saab","Volvo","BMW","Toyota"]


Array

(

    [0] => Saab

    [1] => Volvo

    [2] => BMW

    [3] => Toyota

)

And i dont think there is any prob with json encode/decode process with yii.

ok.The idea is to sort a json file.For that i use this code:




        $paises = file_get_contents(Yii::getPathOfAlias('webroot.assets') . DIRECTORY_SEPARATOR ."country.json");

        $jsondecode=CJSON::decode($paises,true);

       uasort($jsondecode, 'sort');

but i get this error on uasort

sort() expects parameter 1 to be array, string given

This isn’t a JSON::decode() issue. You are using uasort() wrong; the array gets converted to a string for the comparison and it’s not getting a comparison function.

You want to use asort() instead, like so:




$paises = file_get_contents(Yii::getPathOfAlias('webroot.assets') . DIRECTORY_SEPARATOR . "country.json");

$jsondecode = CJSON::decode($paises, true);

asort($jsondecode);
