访问在JSON文件二维数组

Question

我只想把数据转换成JSON文件..

这是我的代码

$inp = file_get_contents('7players.json'); 
    $tempArray = json_decode($inp, true); 
    $arrne['matches']['player1id']="player1"; 
    $arrne['matches']['player2id']="player2"; 
    $arrne['matches']['winner']="winner"; 
    array_push($tempArray['games'], $arrne); 
    $jsonData = json_encode($tempArray); 
    file_put_contents('7players.json', $jsonData); 
    print_r($inp); 

它增加了JSON文件。但它也加入到最后结束..

{"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"},{"name":"Ukraine","image":"\/Images\/ukraine.png","roll_over_image":"tank.jpg"},{"name":"Uzbekistan","image":"\/Images\/uzbekistan.gif","roll_over_image":"tank.jpg"},{"name":"nisha5"},{"name":"nisha1"}], 

"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":"*"}]}]} 

但加入之后，这个文件是如何，在最后..

{"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"},{"name":"Ukraine","image":"\/Images\/ukraine.png","roll_over_image":"tank.jpg"},{"name":"Uzbekistan","image":"\/Images\/uzbekistan.gif","roll_over_image":"tank.jpg"},{"name":"nisha5"},{"name":"nisha1"}], 

"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":"*"}]}, 

{"matches":{"player1id":"player1","player2id":"player2","winner":"winner"}},{"matches":{"player1id":"player1","player2id":"player2","winner":"winner"}},{"matches":{"player1id":"player1","player2id":"player2","winner":"winner"}}]} 

任何帮助将对我很有用...预先感谢了很多！

/* last argument says for decode JSON as array */ 
$gameToUpdate = 0; 
$arrne = json_decode(file_get_contents('7players.json'), true); 
/* play with your JSON here */ 
/* lets suppose that there's lots of matches */ 
$matchToPrepend = array(
    'player1id' => "player1", 
    'player2id' => "player2", 
    'winner' => "winner" 
); 
/* this will prepend data to array */ 
array_unshift($arrne['matches']['games'][$gameToUpdate], $matchToPrepend); 
/* save your JSON */ 
file_put_contents('7players.json', json_encode($arrne)); 

file_put_contents

file_get_contents

array_unshift

json_encode

json_decode

我想你会需要在执行之前进行一些检查，如：检查文件是否存在。
