三种方法教你如何用PHP模拟post提交数据

php模拟post传值在日常的工作中用到的不是很多，但是在某些特定的场合还是经常用到的。

1. <?php
2.  
3. function file_get_contents_post($url, $post){
4.  
5. $options = array(
6. 'http'=> array(
7. 'method'=>'POST',
8. 'content'=> http_build_query($post),
9. ),
10. );
11.  
12. $result = file_get_contents($url,false, stream_context_create($options));
13. return $result;
14.  
15. }
16.  
17. $data = file_get_contents_post("http://www.a.com/post/post.php", array('name'=>'caiknife','email'=>'caiknife#gmail.com'));
18. var_dump($data);

1. <?php
2.  
3. function curl_post($url, $post){
4.  
5. $options = array(
6. CURLOPT_RETURNTRANSFER =>true,
7. CURLOPT_HEADER =>false,
8. CURLOPT_POST =>true,
9. CURLOPT_POSTFIELDS => $post,
10. );
11.  
12.  
13. $ch = curl_init($url);
14. curl_setopt_array($ch, $options);
15. $result = curl_exec($ch);
16. curl_close($ch);
17. return $result;
18. }
19.  
20. $data = curl_post("http://www.a.com/post/post.php", array('name'=>'caiknife','email'=>'caiknife#gmail.com'));
21.  
22. var_dump($data);

1. <?php
2.  
3. function socket_post($url, $post){
4. $urls = parse_url($url);
5. if(!isset($urls['port'])){
6. $urls['port']=80;
7. }
8.  
9. $fp = fsockopen($urls['host'], $urls['port'], $errno, $errstr);
10. if(!$fp){
11. echo "$errno, $errstr";
12. exit();
13. }
14.  
15. $post = http_build_query($post);
16. $length = strlen($post);
17. $header =<<<HEADER
18.  
19. <span class="Apple-tab-span" style="white-space:pre"></span>POST {$urls['path']} HTTP/1.1
20. <span class="Apple-tab-span" style="white-space:pre"></span>Host:{$urls['host']}
21. <span class="Apple-tab-span" style="white-space:pre"></span>Content-Type: application/x-www-form-urlencoded
22. <span class="Apple-tab-span" style="white-space:pre"></span>Content-Length:{$length}
23. <span class="Apple-tab-span" style="white-space:pre"></span>Connection: close
24. <span class="Apple-tab-span" style="white-space:pre"></span>{$post}
25. <span class="Apple-tab-span" style="white-space:pre"></span>HEADER;
26.  
27. fwrite($fp, $header);
28. $result ='';
29. while(!feof($fp)){
30. $result .= fread($fp,512);
31. }
32. $result = explode("\r\n\r\n", $result,2);
33. return $result[1];
34.  
35. }
36.  
37. $data = socket_post("http://www.a.com/post/post.php", array('name'=>'caiknife','email'=>'caiknife#gmail.com'));
38. var_dump($data);
