如何获取没有密钥的json值

Question

i am using php to get the json values and have no problem looping though the data and echoing the SteamName, Level, Experience and more. However I do not know how to echo the steamid number 7656119801319... per proile.

    },

        "UseBlinkArrow": true,
        "AutoToggleBlinkArrow": true
      }
    }
  }
}

My PHP Code:

$url = 'C:\Users\plosey\Desktop\GameServers\Rust\steam\server_syn1\server\syn1\oxide\data\Hunt_Data.json';  //Url to the cars api
$content = file_get_contents($url);
$json = json_decode($content);
    foreach($json->PROFILE as $user) {
          echo $user->SteamName;  
          echo $user->NEED STEAM ID HERE;  // This is the line that is not correct.
} 

so in short i would need to not only echo the SteamName but the Steamid number from the same profile.

Answer 1

Instead of

foreach($json->PROFILE as $user) {

use

foreach ($json->PROFILE as $steamid => $user) {

Answer 2

Try below code to print id. $stremId will print your ID. You can replace it with any variable name.

$json = json_decode($json);
foreach($json->PROFILE as $streamId => $user) {
          echo $user->SteamName;
          echo $streamId;
} 

Answer 3

try this

foreach($json->PROFILE as $key => $user) {
        echo $key .' => '.$user->SteamName."<br/>";
}
