php模拟socket一次连接,多次发送数据的实现代码

 代码如下: 
//post.php
function Post($host,$port)
{
//$host="127.0.0.1";
//建立连接
$conn = fsockopen($host,$port);
if (!$conn)
{
die("Con error");
}
//循环发送5次数据
//
for($i = 0;$i<5;$i++)
{
$data="user_name=admin".$i;
WriteData($conn,$host,$data);
echo $i."
"; 
} 
fclose($conn); 
} 
function WriteData($conn,$host,$data) 
{ 
$header = "POST /test.php 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"; 
//Keep-Alive是关键 
$header.= "Connection: Keep-Alive\r\n\r\n"; 
$header.= "{$data}\r\n\r\n"; 
fwrite($conn,$header); 
//取结果 
//$result = ''; 
//while(!feof($conn)) 
//{ 
// $result .= fgets($conn,128);
