Parsing this JSON file structure

i have a file with inside data formatted in json format:

{
   "data": 

     {

   "users": [


    {

        "ragione_sociale": "",
        "nome": "Annamaria Zaccariello",
        "indirizzo": "",
        "cap": "",
        "citta": "",
        "provincia": "",
        "telefono1": "",
        "telefono2": "",
        "fax": "",
        "cellulare": "",
        "codice_fiscale": "",
开发者_C百科        "newsletter": "1",
        "sesso": "",
        "username": "annamaria.zaccariello@libero.it",
        "scadenza_tessera": "09/08/2012",
        "tipo_tessera": "Red Carpet",
        "stato_tessera": "0",
        "user_id": "1",
        "punti": "0"
    },
    {

        "ragione_sociale": "",
        "nome": "Debora Chessa",
        "indirizzo": "",
        "cap": "",
        "citta": "",
        "provincia": "ge",
        "telefono1": "",
        "telefono2": "",
        "fax": "",
        "cellulare": "3494339496",
        "codice_fiscale": "",
        "newsletter": "1",
        "sesso": "F",
        "username": "debora_c85@hotmail.it",
        "scadenza_tessera": "05/10/2012",
        "tipo_tessera": "Membership",
        "stato_tessera": "0",
        "user_id": "968",
        "punti": "0"
    } 
    ]
     }

}

I need to parse all users one by one and extracting for each one some information "nome", "username", "scadenza_tessera", "tipo_tessera", "stato_tessera", "punti", "provincia", "cellulare"

Anyone can paste PHP code to do this operation ?

Thanks

If you save your json stuff in $myjson you will be able to do something like this:

$myjson = <<< EOT
{
   "data": 

     {

   "users": [


    {

        "ragione_sociale": "",
        "nome": "Annamaria Zaccariello",
        "indirizzo": "",
        "cap": "",
        "citta": "",
        "provincia": "",
        "telefono1": "",
        "telefono2": "",
        "fax": "",
        "cellulare": "",
        "codice_fiscale": "",
        "newsletter": "1",
        "sesso": "",
        "username": "annamaria.zaccariello@libero.it",
        "scadenza_tessera": "09/08/2012",
        "tipo_tessera": "Red Carpet",
        "stato_tessera": "0",
        "user_id": "1",
        "punti": "0"
    },
    {

        "ragione_sociale": "",
        "nome": "Debora Chessa",
        "indirizzo": "",
        "cap": "",
        "citta": "",
        "provincia": "ge",
        "telefono1": "",
        "telefono2": "",
        "fax": "",
        "cellulare": "3494339496",
        "codice_fiscale": "",
        "newsletter": "1",
        "sesso": "F",
        "username": "debora_c85@hotmail.it",
        "scadenza_tessera": "05/10/2012",
        "tipo_tessera": "Membership",
        "stato_tessera": "0",
        "user_id": "968",
        "punti": "0"
    } 
    ]
     }

}
EOT;

$obj=json_decode($myjson);
foreach($obj->data->users as $user){
        echo $user->username;
}

However if you insert invalid JSON $obj will be null. This is not covered by the snippet.
