PHP模拟socket一次连接,多次发送数据的实现代码

代码如下:

1. <?php
   
2. //post.php
   
3. function Post($host,$port)
   
4. {
   
5. //$host="127.0.0.1";
   
6. //建立连接
   
7. $conn = fsockopen($host,$port);
   
8. if (!$conn)
   
9. {
   
10. die("Con error");
    
11. }
    
12. //循环发送5次数据
    
13. //
    
14. for($i = 0;$i<5;$i++)
    
15. {
    
16. $data="user_name=admin".$i;
    
17. WriteData($conn,$host,$data);
    
18. echo $i."<br />";
    
19. }
    
20. fclose($conn);
    
21. }
    
22. function WriteData($conn,$host,$data)
    
23. {
    
24. $header = "POST /test.php HTTP/1.1\r\n";
    
25. $header.= "Host : {$host}\r\n";
    
26. $header.= "Content-type: application/x-www-form-urlencoded\r\n";
    
27. $header.= "Content-Length:".strlen($data)."\r\n";
    
28. //Keep-Alive是关键
    
29. $header.= "Connection: Keep-Alive\r\n\r\n";
    
30. $header.= "{$data}\r\n\r\n";
    
31. fwrite($conn,$header);
    
32. //取结果
    
33. //$result = '';
    
34. //while(!feof($conn))
    
35. //{
    
36. // $result .= fgets($conn,128);
    
37. //}
    
38. //return $result;
    
39. }
    
40. Post('127.0.0.1',80);
    
41. ?>

代码如下:

1. <?php
   
2. //test.php
   
3. $fp = fopen('result.txt','a');
   
4. $data = $_POST['user_name']." -- ". date('Y-m-d H:i:s')."\r\n";
   
5. fwrite($fp,$data);
   
6. fclose($fp);
   
7. ?>
