Я использую только 1 данные для вставки в свой json-файл.
$data=$_POST['myusernamer']; $inp = file_get_contents('7players.json'); $tempArray = json_decode($inp); array_push($tempArray, $data); $jsonData = json_encode($tempArray); file_put_contents('7players.json', $jsonData); Так выглядит мой json-файл. Я просто хочу добавить 1 игрока в конце.
{ "players":[ { "name":"Moldova", "image":"/Images/Moldova.jpg", "roll_over_image":"tank.jpg" }, { "name":"Georgia", "image":"/Images/georgia.gif", "roll_over_image":"tank.jpg" }, { "name":"Belarus", "image":"/Images/Belarus.gif", "roll_over_image":"tank.jpg" }, { "name":"Armenia", "image":"/Images/armenia.png", "roll_over_image":"tank.jpg" }, { "name":"Kazahstan", "image":"/Images/kazahstan.gif", "roll_over_image":"tank.jpg" }, { "name":"Russia", "image":"/Images/russia.gif", "roll_over_image":"tank.jpg" }, ], "games" : [ { "matches" : [ { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":7, "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" } ] }, { "matches" : [ { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":7, "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, { "player1id":"*", "player2id":"*", "winner":"*" }, ] } ] }
Мой вопрос: как добавить игрока в конец? И я также хотел бы знать, как обновлять
player1id":"*", "player2id":"*", "winner":"
в массиве совпадений.
Просто расшифруйте строку json, а затем используйте push массива
$tempArray = json_decode($jsonstring, true); array_push($tempArray, $your_data);
Для вашего случая
$str = '{ "players":[ { "name":"Moldova", "image":"/Images/Moldova.jpg", "roll_over_image":"tank.jpg" }, { "name":"Georgia", "image":"/Images/georgia.gif", "roll_over_image":"tank.jpg" } ]}'; $arr = json_decode($str, true); $arrne['name'] = "dsds"; array_push( $arr['players'], $arrne ); print_r($arr);
Просто проверьте значение print_r ($ arr); Надеюсь, это то, что вы хотите. 🙂
Добавление другого игрока
$tempArray = json_decode($inp, true); array_push($tempArray['players'], array('name' => $data['username'], 'image' => $data['userimage'], 'roll_over_image' => 'tank.jpg'));
Обновление матчей
первый массив совпадений
$tempArray['games'][0]['matches'];
второй массив совпадений
$tempArray['games'][1]['matches'];
теперь являются простыми двумерными массивами с ключами player1id , player2id и winner – их должно быть легко обновить. После этого вы можете закодировать $tempArray на json.
