 post.php
function Post ($host, $port)
{
$host = "127.0.0.1";
Establish a connection
$conn = Fsockopen ($host, $port);
if (! $conn)
{
Die ("Con error");
}
Send 5 data in a loop
//
for ($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/1.1rn";
$header. = "Host: {$host}rn";
$header. = "CONTENT-TYPE:APPLICATION/X-WWW-FORM-URLENCODEDRN";
$header. = "Content-length:". strlen ($data). " RN ";
Keep-alive is the key
$header. = "Connection:keep-alivernrn";
$header. = "{$data}rnrn";
    
Fwrite ($conn, $header);
    
Fetch results
$result = ";
while (!feof ($conn))
//{
$result. = Fgets ($conn, 128);
//}
return $result;
}

Post (' 127.0.0.1 ', 80);
    
?>

 
      test.php
    $fp = fopen (' Result.txt ', ' a ');
    $data = $_post[' user_name '). "--". Date (' y-m-d h:i:s '). " RN ";
    Fwrite ($fp, $data);
    Fclose ($FP);
?>

Then imitate post to realize user login
