This example describes how php uses socket post to send data to other web servers. Share it with you for your reference. The specific implementation method is as follows:

Function post_request ($ url, $ data, $ referer = '') {// Convert the data array into URL Parameters like a = B & foo = bar etc. $ data = http_build_query ($ data); // parse the given URL $ url = parse_url ($ url); if ($ url ['scheme ']! = 'Http') {die ('error: Only http request are supported! ');} // Extract host and path: $ host = $ url ['host']; $ path = $ url ['path']; // open a socket connection on port 80-timeout: 30 sec $ fp = fsockopen ($ host, 80, $ errno, $ errstr, 30); if ($ fp) {// send the request headers: fputs ($ fp, "POST $ path HTTP/1.1 \ r \ n"); fputs ($ fp, "Host: $ host \ r \ n "); if ($ referer! = '') Fputs ($ fp," Referer: $ referer \ r \ n "); fputs ($ fp," Content-type: application/x-www-form-urlencoded \ r \ n "); fputs ($ fp," Content-length :". strlen ($ data ). "\ r \ n"); fputs ($ fp, "Connection: close \ r \ n"); fputs ($ fp, $ data ); $ result = ''; while (! Feof ($ fp) {// receive the results of the request $ result. = fgets ($ fp, 128) ;}} else {return array ('status' => 'err', 'error' => "$ errstr ($ errno) ");} // close the socket connection: fclose ($ fp ); // split the result header from the content $ result = explode ("\ r \ n", $ result, 2 ); $ header = isset ($ result [0])? $ Result [0]: ''; $ content = isset ($ result [1])? $ Result [1]: ''; // return as structured array: return array ('status' => 'OK', 'header' => $ header, 'content' => $ content);} // usage // Submit those variables to the server $ post_data = array ('test' => 'foobar ', 'okay' => 'yes', 'number' => 2); // Send a request to example.com $ result = post_request (' http://www.example.com/ ', $ Post_data); if ($ result ['status'] =' OK ') {// Print headersecho $ result ['head']; echo'

'; // Print the result of the whole request: echo $ result ['content'];} else {echo 'a error occured :'. $ result ['error'];}
