没有输出形式URL与CURL

Question

嗨，大家好我使用我的代码从url获取文件数据我测试了curl函数的工作，但我不知道我的代码有什么问题，因为我没有任何输出请求可以有人告诉我该怎么解决，我想我有问题，本节：

foreach($serverlist as $line) { 
$line = trim($line); 

，但我不知道如何解决这个问题：

<?php 

function get_data($url) 
{ 
    $ch = curl_init(); 
    $timeout = 5; 
     curl_setopt($ch, CURLOPT_URL, $url); 
     curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0)"); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,false); 
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false); 
     curl_setopt($ch, CURLOPT_MAXREDIRS, 10); 
     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
     curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
     $data = curl_exec($ch); 
     curl_close($ch); 
    return $data; 
} 

$serverlist = get_data("http://185.49.84.109/iw5msl/serverinfo.txt"); 
$file_headers = @get_headers($serverlist); 

if(($file_headers[0] == 'HTTP/1.0 404 Not Found') || ($file_headers[0] == 'HTTP/1.0 302 Found' && $file_headers[7] == 'HTTP/1.0 404 Not Found')) 
{ 
    echo "The server list is currently being changed due to some upgrades and therefore not available. Sorry for any inconvenience."; 
} else { 

$odd = false; 
foreach($serverlist as $line) { 
$line = trim($line); 
list($name,$ip,$players,$map,$type,$mod,$country) = explode("|!|!|", $line . "|!|!|"); 
$ixp = explode(":", $ip); 
if(in_array($ixp[0], file("data/servers.banlist")) || in_array($ip, file("data/servers.banlist"))) continue; 
$type = parse_gametype($type); 
$map = @$_MAPS["mw3"][$map]; 
if(strstr($map, "<") > -1) $map = "Server by idiot."; 
list($players,$maxplayers) = explode("/", $players); 
$country = "<span style=\"display:none\">$country</span><img alt=\"$country\" title=\"$country\" src=\"".parse_flag($country)."\" />"; 
?> 
<tr style="height: 50px"> 
          <td style="text-align:left"><span style="display: none"><?php echo preg_replace("/[^a-zA-Z0-9\s]/", "", strip_tags($name)); ?></span> 
           <span style="font-size: 1.5em; font-family: 'Play', 'OCR A Extended'"><?php echo $name; ?></span><br /> 
           <span style="font-size: 1.3em"><?php echo $ip; ?></span> 
          </td> 
          <td style="text-align: right; font-size: 1.5em"><?php echo $players; ?></td> 
          <td style="font-size: 1.5em">/</td> 
          <td style="text-align: left; font-size: 1.5em; width: 50px"><?php echo $maxplayers; ?></td> 
          <td style="font-family: Electrolize; letter-spacing: 1px; font-size: 1.4em; text-align:right; display: color:white;background-size:100%;background-position:center center;background-image:url(<?php echo $map_thumb; ?>)"> 
           <div class="blackgradient gradient"><?php echo $map; ?></div> 
          </td> 
          <td><?php echo $type; ?></td> 
          <!--<td><?php echo $mod; ?></td>--> 
          <td><?php echo $country; ?></td> 
         </tr> 
<?php $odd = !$odd; ?> 
<?php } ?> 
        </tbody></table> 
<?php } ?>

试加

$serverlist=explode("\n", $serverlist); 

在FOREACH行之前。

Thx，应该是"\n"。

对于在尾部的空行，请使用在foreach附近：

$serverlist=explode("\n", $serverlist); //ADDED 
$odd = false; 
foreach($serverlist as $line) { 
$line = trim($line); 
if(empty($line))continue; //ADDED
