json_encode数组的特定部分

Question

$array = array("Real" => array("Alonso","Zidan"),"Inter" => "Zanetti", "Roma" => "Toti");
$json=json_encode($array);
echo $json

By this way I am reading all the data, but how can I read the data of only Real or Inter?

For example, if it is json_decoded I can do so:

1. For Inter:

   echo $array['Inter'];
   

2. For Real:

   foreach($array["Real"] as $real){ 
       echo $real."<br>";
   }
   

How can I do the same with json_encode()?

Answer 1

As I understand your question you need to output the json`d object.

Input

$input = '{"Real":["Alonso","Zidan"],"Inter":"Zanetti","Roma":"Toti"}';

In php:

// Second true is for array return, not object)
$string = json_decode($input, true) 
echo $string['Inter'];

In Javascript (jQuery):

var obj = jQuery.parseJSON(input);
if (obj != undefined) {
    echo obj['Inter'];
}

UPD:

If you need to get an json in all arrays you need to make follow:

$array = array("Real" => array("Alonso","Zidan"),"Inter" => "Zanetti", "Roma" => "Toti");
foreach($array as $key => $value) {
    $array[$key] = json_encode($value);
}

After this code all variables in array will be json`ed and you can echo them in any time
