小编给大家分享一下php中curl异步并发请求http的示例，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
先来看下同步的代码以及请求时间。
$start_time=date("h:i:sa");
for ($i=0; $i <100 ; $i++) {
$urls[]="http://www.downxia.com/downinfo/2315".$i.".html";
GetTitle(geturl("http://www.downxia.com/downinfo/2315".$i.".html"));
}
function geturl($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
function GetTitle($output){
preg_match('/.*<\/title>/i',$output,$matches);
var_dump($matches[0]);
}
$end_time=date("h:i:sa");
echo '开始时间是：'.$start_time;
echo '结束时间是：'.$end_time;</pre><p><img src="/upload/otherpic41/2207.jpg" alt="php中curl异步并发请求http的示例"></p><p>最下面可以看到时间花了27秒。</p><p>接下来看下php curl 异步并发请求http的代码以及花费时间。</p><pre>$start_time=date("h:i:sa");
