how to get elements from this JSON in php

How can i get the values of the field password from this json in php 

[  
   {  
      "rid":"#145:0",
      "version":1,
      "oClass":"Login",
      "oData":{  
         "Password":"hacker007",
         "role":null,
         "Name":"Nijeesh Joshy",
         "Email":"[email protected]"
      }
   }
]

this is my code

$json = '[  
   {  
      "rid":"#145:0",
      "version":1,
      "oClass":"Login",
      "oData":{  
         "Password":"hacker007",
         "role":null,
         "Name":"Nijeesh Joshy",
         "Email":"[email protected]"
      }
   }
]';

$json = json_decode($json,true);

echo $json[0]->oData->Name;

I am getting this error

Notice: Trying to get property of non-object

I see that after the json_decode() step, the properties are not protected anymore : 

$json_data = '[
    {
        "rid":"#145:0",
        "version":1,
        "oClass":"Login",
        "oData":{
            "Password":"hacker007",
            "role":null,
            "Name":"Nijeesh Joshy",
            "Email":"[email protected]"
        }
    }
]';

$data = json_decode($json_data);

So, you could access the data this way : 

$array['name'] = $data[0]->oData->Name;
$array['password'] = $data[0]->oData->Password;

var_dump($array);

Output : 

array(2) { 
    ["password"]=> string(9) "hacker007" 
    ["name"]=> string(13) "Nijeesh Joshy" 
}

note :

The classes used to build the original data array must give you methods to get the data in a proper way.
