出现错误“致命错误：最大执行时间超过30秒”

Question

我在github上发现了一个iplog垃圾邮件发送者，当我设置它时，我不断收到错误消息  “致命错误：超过30秒的最大执行时间”

<?php
set_time_limit(0);
$url = 'https://2no.co/2J9n55';

$proxylist = file("proxy.txt", FILE_SKIP_EMPTY_LINES | 
FILE_IGNORE_NEW_LINES);
foreach($proxylist as $proxy){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_exec($ch);
    echo "/";
}
?>

我正在使用XAMPP并通过localhost运行代码。
