试图将 json 文件解码为变量,但它只返回 null

trying to decode json file to variable but its only returning null

我正在尝试将 json 文件解码为 PHP 变量,但 PHP 变量仅为空。这是我的 PHP:

$champions['names'] = json_decode(file_get_contents("file://D:/Xampp/htdocs/lol-champions.json"),true);
echo $champions['names']['champions'][1]['name'];

这是我的 json 文件:

"champions":[
{
  "id" : 103,
  "name" : "Ahri",
},
{ 
  "id" : 84,
  "name" : "Akali",
}]

正如@Paul Crovella 所说,这是正确的版本:

{
"champions": [{
    "id": 103,
    "name": "Ahri"
}, {
    "id": 84,
    "name": "Akali"
}]
}

另外如果你想调用它;

echo $champions->champions[1]->name;
