获取此错误

[Tue Aug 18 14：41：57.614006 2015] [：error] [pid 21389] [client 67.90.138.68:5794] PHP警告：file_get_contents（http://steamcommunity.com/market/priceoverview/?appid=295110&currency=1&market_hash_name=BR：Vigilante Crate）：无法打开流： HTTP请求失败！ HTTP / 1.0 500内部服务器错误\ r \ n

<?php
foreach($json2['rgDescriptions'] as $i){
$item = $i['market_name'];
$icon = $i['icon_url'];
$fetchdata = 'http://steamcommunity.com/market/priceoverview/?appid=295110&currency=1&market_hash_name=' . $item;
$grab = file_get_contents($fetchdata);
$id = json_decode($grab, true);
echo '<img src="'. $imgurlbase . $icon . '/64fx64f">' . '<a class="btn btn-primary btn-lg" href="#" role="button">' . $item . '</a>'. '<a class="btn btn-primary btn-lg" href="#" role="button">'. $id['lowest_price'].'</a>'.'<br>';
}

出于某种原因＆amp;在基本网址中传递的是＆＃39;＆amp;安培;＆＃39;每次都在网址中而不是＆amp;

我不是最好的PHP，但我正在寻找的任何东西都没有提出原因。它与json_decode有关吗？这是我唯一的猜测。

你需要对字符串进行编码：

$fetchdata = 'http://steamcommunity.com/market/priceoverview/?appid=295110&currency=1&market_hash_name=' . urlencode($item);

适合我：

php > $fetchdata ='http://steamcommunity.com/market/priceoverview/?appid=295110&currency=1&market_hash_name='.urlencode('BR: Vigilante Crate');
php > $grab = file_get_contents($fetchdata);
php > print_r(json_decode($grab));
stdClass Object
(
    [success] => 1
    [lowest_price] => $0.07
    [volume] => 4,994
    [median_price] => $0.07
)

PHP json url没有正确传递替换＆amp;与＆amp;
