如何重新编写我的PHP脚本以尽快运行？

Question

我正在运行一个脚本,它将检查域名的可用性(10次)并输出域(如果可用)和时间戳(以毫秒为单位).

你能找到一些甚至在婚礼上放慢脚本速度的东西吗？如果你可以请调整和重新发布或建议可以做得更好,这将是非常感谢!谢谢.

<?php

    date_default_timezone_set('Australia/Brisbane');
    $loops = 0; 

    function udate($format, $utimestamp = null) {
      if (is_null($utimestamp))
        $utimestamp = microtime(true);

      $timestamp = floor($utimestamp);
      $milliseconds = round(($utimestamp - $timestamp) * 1000000);

      return date(preg_replace('`(?<!\\\\)u`', $milliseconds, $format), $timestamp);
    }

    function GetCurlPage ($pageSpec)
    {
      $ch = curl_init($pageSpec);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
      $tmp = curl_exec ($ch);
      curl_close ($ch);
      $tmp = preg_replace('/(?s)<meta http-equiv="Expires"[^>]*>/i', '', $tmp);
      $tmp = explode('<br>', $tmp);
      foreach ($tmp AS $line) {
        //echo '<pre>';
        //print_r($line);
        //echo '</pre>';
      }
      // Do something with each line.
      echo $tmp[0];
      echo "<br>";
      echo $tmp[1];
      //echo $tmp[2];
      echo "<br>";
      echo udate('H:i:s:u');
      echo "<br><br>";

      return $tmp;

    }

    while ($loops <= 10)    
    {
$suffixes=urlencode("com.au");
$domain = "sampledomain";
$fuzzysearch = "0";
$returnUrl="http://mydomain.com.au/test.php";
$url = "https://apidomain.com.au/check.php?domain=" .
$domain . "&suffixes=" . $suffixes . "&fuzzysearch=" . $fuzzysearch;
$output = GetCurlPage("$url");

    ++$loops;
    }           
?>

因为你需要对外部网站进行10次卷曲,所以速度很慢

两个建议

• 更新你的test.php/check.php以允许在一次curl调用时检查多个域名(而不是逐个检查,传递一个数组)
• 使用curl_multi_exec允许同时并行卷曲10个不同的URL
