            [game] => bf4
            [plat] => pc

            [country] => 
            [countryName] => 
            [rank] => stdClass Object
                (
                    [nr] => 73
                    [imgLarge] => bf4/ranks/r73.png
                    [img] => r73

                            [name] => Chief Warrant Officer Five IV
                            [needed] => 5030000
                            [curr] => 5022060
                            [relNeeded] => 110000

                        )

                )

            [score] => 5025100
            [timePlayed] => 862027
            [uId] => 2832659368608119092
            [uName] => HeLLTiMe
            [uGava] => 0b8b00021ebfb32414e5a6051c2c9a40

            [adminable] => 
            [linked] => 
        )

    [stats] => stdClass Object
        (
            [reset] => stdClass Object
                (
                    [lastReset] => 0
                    [score] => 0
                    [timePlayed] => 0
                    [timePlayedSinceLastReset] => 0

                    [numWins] => 0
                )

How can I fetch this data?

Here is my code:

<?php
$url = "http://api.bf4stats.com/api/playerInfo?plat=pc&name=HeLLTiMe";
$json = file_get_contents($url);

$data = json_decode($json);
echo "<pre>";
print_r($data);
?> 

Answer 1

to get the name you should do this:

echo $data->player->name;

You need this because you have a stdClass Object

You can also change the out to just a array, you have to change this:

$data = json_decode($json);

to this:

$data = json_decode($json, true);

When you make this chagne you can get the value by this:

echo $data['player']['name'];

Edit

Below you can see the example, this works for me with no error.

$url = "http://api.bf4stats.com/api/playerInfo?plat=pc&name=HeLLTiMe";
$json = file_get_contents($url);

echo 'Using stdClass Object option<br>';
$data = json_decode($json);
echo $data->player->name;

echo '<br><br>Using Array option<br>';
$data = json_decode($json, true);
echo $data['player']['name'];

exit;

Answer 2

$result = array();

$result['name'] = $data->Player->name

var_dump($result);

Answer 3

不确定通过已获取的数据来获取数据是什么意思，但是如果您询问如何访问字段，则可以这样做。

print_r($data->player->name);
