Question

我使用Google财经API，当我点击表单中的转换时出现此错误：

<br /> <b>Warning</b>: file_get_contents(https://finance.google.com/finance/converter?a=SDG&amp;from=CAD&amp;to=+1): failed to open stream: HTTP request failed! HTTP/1.0 503 Service Unavailable
 in <b>convert_api.php</b> on line <b>12</b><br /> <br /> <b>Notice</b>: Undefined offset: 1 in <b>\convert_api.php</b> on line <b>14</b><br /> <br /> <b>Notice</b>: Undefined offset: 1 in <b>C:\xampp\htdocs\c\convert_api.php</b> on line <b>15</b><br />

convert_api.php

<?php
$params = $_REQUEST;
//print_R($params);die('fff');
if(isset($params) && isset($params['amount']) && isset($params['from']) && isset($params['from'])) {
    currencyConverter($params['from'], $params['to'], $params['amount']);
}

function currencyConverter($amount,$from_currency,$to_currency) {
    $amount = urlencode($amount);
    $from_currency = urlencode($from_currency);
    $to_currency = urlencode($to_currency);
    $get = file_get_contents("https://finance.google.com/finance/converter?a=$amount&from=$from_currency&to=$to_currency");
    $get = explode("<span class=bld>",$get);
    $get = explode("</span>",$get[1]);
    $converted_currency = preg_replace("/[^0-9\.]/", null, $get[1]);
    echo $converted_currency;
}
?>

我尝试将urlencode（）用于网址，但它无效。

我读过curl是更好的情况但不想使用curl。

我知道如何让它发挥作用？

警告：file_get_contents，未定义的偏移量：
