title: PHP faster than cURL?
body: <p>what is the fastest way to get the http status code.
  I have a list within about 10k URL's to check. And in best case it checks them every 15 minutes.
  So i've a php script what uses simple curl functions and loop through them all. But it takes way too much time. 
  Any suggestions what i can do to improve that? What about parallel checks on multiple urls? how many could php manage? I'm very new to this whole performance thing. </p>
  
  <p>This is what i have:</p>
  
  <pre><code>public function getHttpStatus(array $list) {
      $list = array(…); // Array contains 10k+ urls from database.
      for($i = 0; $i &lt; count($list); $i++) {
              $ch = $list[$i];
          curl_setopt($ch, CURLOPT_NOBODY, 1); 
          curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE); 
          curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
          curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
  
          $c = curl_exec($ch); 
          $info = curl_getinfo($ch);
          echo $info['http_code'] . '&lt;br /&gt;';
      }
  }
  </code></pre>
  
  <p>Thanks in advance! </p>
