深入解析fsockopen与pfsockopen的区别

我写了个代码了一下:

复制代码 代码如下:

<?php

$data="1,0,721,73,1,0,0,43290000,0,60D81D509BC00451,3,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)."<hr><br />";

}

$middleTime = microtime(true);

for ($index = 0; $index < $times; $index++) {

echo httpPost($host,$url,$data,!$pffirst)."<hr><br />";;

}

$endTime = microtime(true);

echo ($pffirst?"pfsocket":"fsocket").":".($middleTime-$startTime);

echo "<br />";

echo ($pffirst?"fsocket":"pfsocket").":".($endTime-$middleTime);

$count=0;

//发包函数

function httpPost($host,$url,$data,$p)

{

global $count;

$func = $p?"pfsockopen":"fsockopen";

$conn = $func($host,80,$errno, $errstr, 30);

if (!$conn)

{

echo "$errstr ($errno)<br />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."<br /><br />";

$resp='';

//while (!feof($conn)) {

// $resp .= fgets($conn);
