导读：本篇文章是对fsockopen与pfsockopen的区别进行了详细的分析介绍，需要的朋友参考下

按手册上说,这两个函数的唯一区别是,

pfsockopen

是持续连接,而

fsockopen

不是.

我写了个代码了一下:

<div class="codetitle"><a style="CURSOR: pointer" data="85712" class="copybut" id="copybut85712" onclick="doCopy('code85712')"> 代码如下:<div class="codebody" id="code85712">
<?php
$data="1,721,73,1,43290000,60D81D509BC00451,3,FFFFFFFF";
//http://10.144.99.114/SANEX_NEW/modules/subscribemanager/test.php
$host = '127.0.0.1';
$url = "/aa.php";
$pffirst = false;
$times = 1000;
$startTime = microtime(true);
for ($index = 0; $index < $times; $index++) {
echo httpPost($host,$url,$data,$pffirst)."

";
}
$middleTime = microtime(true);
for ($index = 0; $index < $times; $index++) {
echo httpPost($host,!$pffirst)."

";;
}
$endTime = microtime(true);
echo ($pffirst?"pfsocket":"fsocket").":".($middleTime-$startTime);
echo "
";
echo ($pffirst?"fsocket":"pfsocket").":".($endTime-$middleTime);$count=0;
//发包函数
function httpPost($host,$p)
{
global $count;
$func = $p?"pfsockopen":"fsockopen";$conn = $func($host,80,$errno,$errstr,30);
if (!$conn)
{
echo "$errstr ($errno)
n";
return;
}$header = "POST ".$url." HTTP/1.1rn";
$header.= "Host : {$host}rn";
$header.= "Content-type: application/x-www-form-urlencodedrn";
$header.= "Content-Length:".strlen($data)."rn";
$header.= "Connection: Keep-Alivernrn";
$header.= "{$data}rnrn";fwrite($conn,$header);$count++;
echo $count.' '.$header."

";$resp='';
//while (!feof($conn)) {
//$resp .= fgets($conn);
/
