[{"Obj" :    
        { "ID":"11",
          "NAME":"XYZ",
          "GENDER":"M" 
        }
}]

How can i do this?

Answer 1

Try this,

<?php
    $json='[{"Obj" :    
            { "ID":"11",
              "NAME":"XYZ",
              "GENDER":"M" 
            }
    }]';
    $jsonArray=json_decode($json);
    echo $jsonArray[0]->Obj->ID;
?>

Answer 2

assuming that your json string is inside a post parameter:

$json_string = $_POST['json'];

using json_decode you can convert a json string to a php object:

$json = json_decode($json_string);

and then access to your ID:

$id = $json[0]->Obj->ID;

if you want to convert the object into associative array just do this:

$json = (array)$json;

and access to your id:

$id = $json[0]['Obj']['ID'];

Answer 3

Decode the json output using json_decode and put true as second parameter. It will give you array output.

$arr = json_decode($json,true);
echo $arr[0]['Obj']['ID'];
