深入解析fsockopen与pfsockopen的区别  

　　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=" D D BC FFFFFFFF"; // $host = ; $url = "/aa php"; $pffirst = false; $times = ; $startTime = microtime(true); for ($index = ; $index < $times; $index++) {  echo Post($host $url $data $pffirst) "<hr><br />"; } $middleTime = microtime(true); for ($index = ; $index < $times; $index++) {  echo Post($host $url $data !$pffirst) "<hr><br />";; } $endTime = microtime(true);  echo ($pffirst?"pfsocket":"fsocket") ":" ($middleTime $startTime);  echo "<br />";  echo ($pffirst?"fsocket":"pfsocket") ":" ($endTime $middleTime); $count= ; //发包函数 function Post($host $url $data $p) { global $count;  $func = $p?"pfsockopen":"fsockopen";  $conn = $func($host $errno $errstr );  if (!$conn)  {   echo "$errstr ($errno)<br />n";   return;  }  $header = "POST " $url " HTTP/ rn";  $header = "Host : {$host}rn";  $header = "Content type: application/x 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);  //}  //fclose($conn);  return $resp; } ?> lishixinzhi/Article/program/PHP/201311/20862
