方法一：HTTP函数发送方式

说明：$data为POST发送的数据：$key为参数名，$val为参数值

[php]view plaincopy

1. $URL = "http://pre.payment.sdoa.sdo.com/";

2. $data = $key1."=".val1."&".$key2."=".val2;

3. $PostResult = http_post_data($BGWURL,$data );
   
   
   方法二：Curl Post数据
   

   [php]view plaincopy

   
   

   方法三：fsockopen方式

   说明：$data为POST发送的数据：$data为数组形式

   [php]view plaincopy

   
   

1. function posttohost($url, $data) {

2. $url = parse_url($url);

3. if (!$url) return"couldn't parse url";

4. if (!isset($url['port'])) { $url['port'] = ""; }

5. if (!isset($url['query'])) { $url['query'] = ""; }

6. $encoded = "";

7. while (list($k,$v) = each($data)) {

8. $encoded .= ($encoded ? "&" : "");

9. $encoded .= rawurlencode($k)."=".rawurlencode($v);

10. }

11. $fp = fsockopen($url['host'], $url['port'] ? $url['port'] : 80);

12. if (!$fp) return"Failed to open socket to $url[host]";

13. fputs($fp, sprintf("POST %s%s%s HTTP/1.0/n", $url['path'], $url['query'] ? "?" : "", $url['query']));

14. fputs($fp, "Host: $url[host]/n");

15. fputs($fp, "Content-type: application/x-www-form-urlencoded/n");

16. fputs($fp, "Content-length: " . strlen($encoded) . "/n");

17. fputs($fp, "Connection: close/n/n");

18. fputs($fp, "$encoded/n");

19. $line = fgets($fp,1024);

20. if (!eregi("^HTTP/1/.. 200", $line)) return;

21. $results = ""; $inheader = 1;

22. while(!feof($fp)) {

23. $line = fgets($fp,1024);

24. if ($inheader && ($line == "/n" || $line == "/r/n")) {

25. $inheader = 0;

26. }

27. elseif (!$inheader) {

28. $results .= $line;

29. }

30. }

31. fclose($fp);

32. return$results;

33. }

1. function _curl_post($url, $vars) {

2. $ch = curl_init();

3. curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);

4. curl_setopt($ch, CURLOPT_URL,$url);

5. curl_setopt($ch, CURLOPT_POST, 1 );

6. curl_setopt($ch, CURLOPT_HEADER, 0 ) ;

7. curl_setopt($ch, CURLOPT_POSTFIELDS, "var=".$vars);

8. $data = curl_exec($ch);

9. curl_close($ch);

10. if ($data)

11. return$data;

12. else

13. return false;

14. }
