如何重新编码我的 php 脚本以尽快运行? [英] How can I re-code my php script to run as quickly as possible?

问题描述

我正在运行一个脚本，该脚本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).

你能找到任何会减慢脚本速度的东西吗?如果您可以调整并重新发布或建议可以做得更好的地方，将不胜感激！谢谢.

';//print_r($line);//echo '</pre>';}//对每一行做一些事情.回声 $tmp[0];echo "
";回声 $tmp[1];//echo $tmp[2];echo "
";echo udate('H:i:s:u');echo "<br><br>";返回 $tmp;}while ($loops <= 10){$suffixes=urlencode("com.au");$domain = "sampledomain";$fuzzysearch = "0";$returnUrl="http://mydomain.com.au/test.php";$url = "https://apidomain.com.au/check.php?domain=" .$域."&suffixes=" .$后缀."&fuzzysearch=".$模糊搜索；$output = GetCurlPage("$url");++$循环；}?>
解决方案
慢，因为你需要使 10 curl 到外部站点
两个建议
更新您的 test.php/check.php 以允许在一次 curl 调用中检查多个域名(而不是逐一检查，传递一个数组)
使用 curl_multi_exec 允许并行 curl 10 个不同的 URL同时
我更喜欢建议 1
I'm running a script which will check the availability (10 times) of a domain name and output the domain, if available and a timestamp (with milliseconds).

Can you find anything which is slowing down the script even marignally?
If you could please adjust and re-post or advise what can be done better, it would be very much appreciated! Thank you.
<?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;
    }           
?>

解决方案
The slowness because you need to make 10 curl to external site

Two suggestions


update your test.php/check.php to allow multiple domain name check at one curl call (instead of checking one-by-one, pass an array)
use curl_multi_exec to allow parallel curl 10 different URLs at the same time


I would prefer suggestion 1
