Dane które będą pobranę chce nałożyć na obrazek (PHP + GD).

Niestety nie miałem żadnego kontaktu z json, który jest porównywalny do xml'a.
Jakby ktoś dał przykład w jaki sposób pobrać dane typu:
Kod
"place": 759270,
"value": 406
"spotted": 0,
"localized_name": "T-50",
"name": "T-50",
"level": 4,
"damageDealt": 0,
"survivedBattles": 0,
"battle_count": 31,
"nation": "ussr",
"image_url": "/static/2.1.2/encyclopedia/tankopedia/vehicle/small/ussr-t-50.png",
"frags": 0,
"win_count": 14,
"class": "lightTank"


Z góry dziekuję, nawet za nakierownia jak to zrobić.
Aktualnie mam skrypt PHP który wyszukje te dane z html'a, ale nie wszytskie dane są tam pokazywane.

ja uzywam jsona do pobierania danych ajaxem, np:

skrypt.php
[PHP] pobierz, plaintext 
  1. $godzina = date('H:i');
  2. echo json_encode($godzina);
[PHP] pobierz, plaintext


jakis inny plik, niekoniecznie js
[JAVASCRIPT] pobierz, plaintext 
  1. $.ajax({
  2. type : "POST",
  3. url : "skrypt.php",
  4. dataType : "json",
  5. data : {},
  6. success (json)
  7. {
  8.  alert(json['godzina']);
  9. }
  10. });
[JAVASCRIPT] pobierz, plaintext


przyznam ze nei interesowalem sie jak ich uzywac w php, ale mysle ze po prostu przelec po stringu z uzyciem explode albo cos podobnego.. zalezy ktorych danych potrzebujesz i co dokladnie zamierzasz z nimi zrobic

Każda klamra to kolejny array, więc mając np coś takiego:

{ "data": { "place": 759270, "value": 406... } }

pobierasz sobie json skąd tam masz i możesz zrobić

[PHP] pobierz, plaintext 
  1. $json->place; //output: 759270
[PHP] pobierz, plaintext
Piogola
14.11.2012, 20:58:22

  1. $tablica = json_decode(file_get_contents('plik_json.txt'));

Już Ci pisałem mniej więcej, najpierw pobaw się z tym co ja Ci dałem.

Dałem tak:
[PHP] pobierz, plaintext 
  1. <?php
  2. if(!function_exists("curl_init")) die("cURL nie jest zainstalowany");
  3.  
  4. $url = 'plik.json';
  5.         $curl = curl_init();
  6.         curl_setopt( $curl, CURLOPT_URL, $url );
  7.         curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
  8.         $result = curl_exec( $curl );
  9.         curl_close( $curl );
  10.         $return = json_decode($result, true);
  11.  
  12.         print_r ($return);
  13. ?>
[PHP] pobierz, plaintext

i teraz pod $return mam tablice.
