深入解析fsockopen与pfsockopen的区别_PHP

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:
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)."

";
}
$middleTime = microtime(true);
for ($index = 0; $index < $times; $index++) {
echo httpPost($host,$url,$data,!$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,$url,$data,$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/1.1\r\n";
$header.= "Host : {$host}\r\n";
$header.= "Content-type: application/x-www-form-urlencoded\r\n";
$header.= "Content-Length:".strlen($data)."\r\n";
$header.= "Connection: Keep-Alive\r\n\r\n";
$header.= "{$data}\r\n\r\n";

fwrite($conn,$header);

$count++;
echo $count.' '.$header."

";

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