我的php代码如下所示：

<?php
$fgc = json_decode(file_get_contents("https://api.kraken.com/0/public/Trades?pair=XXBTZEUR&since=0"), true);

$contents = $fgc["result"];
  foreach($contents as $details){
    echo "".$details["XXBTZEUR"];
    echo PHP_EOL;

  }

?>

Answer 1

以下PHP示例代码可能有助于您入门。

$fgc = json_decode(file_get_contents("https://api.kraken.com/0/public/Trades?pair=XXBTZEUR&since=0"), true);

// Was there a problem getting the data?
if ((! $fgc) || ($fgc['error'])) {
    echo 'Error getting the data';
    exit;
}

// We have data. Dump some to see what we have
echo '<pre>';
foreach($fgc['result']['XXBTZEUR'] as $k => $v) {
    var_dump($v);
}
echo '</pre>';

这会吐出1000个这样的条目：

array(6) {
  [0]=>
  string(8) "97.00000"
  [1]=>
  string(10) "1.00000000"
  [2]=>
  float(1378856831.546)
  [3]=>
  string(1) "s"
  [4]=>
  string(1) "m"
  [5]=>
  string(0) ""
}

所以看起来每个条目都有六个元素。我假设元素在某处记录。

Answer 2

你可以尝试这个，得到你期望的答案：

$fgc = json_decode(file_get_contents("https://api.kraken.com/0/public/Trades?pair=XXBTZEUR&since=0"), true);

$contents = $fgc["result"];

foreach ($contents['XXBTZEUR'] as $details) {

    echo"<pre>";
    print_r($details);
    echo PHP_EOL;
}

php文件获取Kraken API的内容json
