我正在尝试列出 20,000 多个域名并检查它们是否“活着”。我真正需要的只是一个简单的 http 代码检查,但我不知道如何使用 curl_multi。在我使用的单独脚本上,我有以下函数,它同时检查一批 1000 个域并返回 json 响应代码。也许这可以修改为只获取http响应代码而不是页面内容?
(对不起,我无法将其粘贴为一个很好的代码块,而无需逐行添加 4 个空格...(也尝试跳过一行并添加 8 个空格)
$dotNetRequests = 域数组...
//loop through arrays
foreach(array_chunk($dotNetRequests, 1000) as $Netrequests) {
    $results = checkDomains($Netrequests);
    $NetcurlRequest = array_merge($NetcurlRequest, $results);
}
function checkDomains($data) {
// array of curl handles
$curly = array();
// data to be returned
$result = array();
// multi handle
$mh = curl_multi_init();
// loop through $data and create curl handles
// then add them to the multi-handle
foreach ($data as $id => $d) {
$curly[$id] = curl_init();
$url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
curl_setopt($curly[$id], CURLOPT_URL,            $url);
curl_setopt($curly[$id], CURLOPT_HEADER,         0);
curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);
// post?
if (is_array($d)) {
  if (!empty($d['post'])) {
    curl_setopt($curly[$id], CURLOPT_POST,       1);
    curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
  }
}
curl_multi_add_handle($mh, $curly[$id]);
  }
  // execute the handles
  $running = null;
  do {
    curl_multi_exec($mh, $running);
  } while($running > 0);
  // get content and remove handles
  foreach($curly as $id => $c) {
     // $result[$id] = curl_multi_getcontent($c);
// if($result[$id]) {
if (curl_multi_getcontent($c)){
    //echo "yes";
    $netName = $data[$id];
    $dName = str_replace(".net", ".com", $netName);
    $query = "Update table1 SET dotnet = '1' WHERE Domain = '$dName'";
    mysql_query($query);
}
curl_multi_remove_handle($mh, $c); 
}
// all done
 curl_multi_close($mh);
return $result;
}
