php 发送url 方式

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 plain copy

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 plain copy

   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. }

   
   

   方法三：fsockopen方式

   说明：$data为POST发送的数据：$data为数组形式

   [php] view plain copy

   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. }
