我只使用1个数据插入我的json文件。
$data=$_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);
所以这就是我的json文件的样子。我只想在最后添加1个玩家。
{
"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":"*"
},
]
}
]
}
我的问题是，如何在最后添加播放器？我还想知道如何更新
player1id":"*",
"player2id":"*",
"winner":"
。

只需解码你的json字符串然后使用数组推送
$tempArray = json_decode($jsonstring, true);
array_push($tempArray, $your_data);
对于你的情况
$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);
只需检查print_r（$ arr）的值;我希望这就是你想要的。 ：）

添加其他玩家
$tempArray = json_decode($inp, true);
array_push($tempArray['players'], array('name' => $data['username'], 'image' => $data['userimage'], 'roll_over_image' => 'tank.jpg'));
更新匹配
第一个匹配数组
$tempArray['games'][0]['matches'];
第二个匹配数组
$tempArray['games'][1]['matches'];
现在是带有键player1id，player2id和winner的简单二维数组 - 应该很容易更新这些数组。
之后，您可以将$tempArray编码回json。

$arr = json_decode($str, true);//decode it
$arrne['players'] = "sadaadad";

在核心PHP中
如果要在JSON响应上放置数组。那么您可以使用此代码。
非常简单的方法，您可以使用以下步骤。
1）步骤，您必须使用 json_decode（）将JSON转换为数组。
2）使用array_merge（）方法添加新数组。如果您有兴趣添加数组。
$staff = json_decode($staffRes ,true);
$driver = ["helpers"=>[id=>1,name=>hep1],[id=>2,name=>hep2]]
$profile= array_merge($staff ,$driver );
在Laravel中
$staff = collect($staffRes)->toArray() ; // json() also work here.
$driver = ["helpers"=>[id=>1,name=>hep1],[id=>2,name=>hep2]]
$profile= array_merge($staff ,$driver );

使用此php代码
<?php
$message = '';
$error = '';
if(isset($_POST["submit"]))
{
if(empty($_POST["title"]))
{
$error = "<label class='text-danger'>Enter details</label>";
}
else if(empty($_POST["image"]))
{
$error = "<label class='text-danger'>Enter Posted By</label>";
}
else
{
if(file_exists('myfile.json'))
{
$current_data = file_get_contents('myfile.json');
$array_data = json_decode($current_data, true);
$extra = array(
'title' => $_POST['title'],
'image' => $_POST["image"],
);
$array_data[] = $extra;
$products['products']=$array_data[];
$final_data = json_encode($products);
if(file_put_contents('myfile.json', $final_data))
{
$message = "<label class='text-success'>Added Successfully</p>";
}
}
else
{
$error = 'JSON File not exits';
}
}
}
?>
