<?php // // simple php example sends http post remote site //  $ch = curl_init();  curl_setopt($ch, curlopt_url,"http://www.example.com/tester.phtml"); curl_setopt($ch, curlopt_post, 1); curl_setopt($ch, curlopt_postfields,             "postvar1=value1&postvar2=value2&postvar3=value3");  // in real life should use like: // curl_setopt($ch, curlopt_postfields,  //          http_build_query(array('postvar1' => 'value1')));  // receive server response ... curl_setopt($ch, curlopt_returntransfer, true);  $server_output = curl_exec ($ch);  curl_close ($ch);  // further processing .... if ($server_output == "ok") { ... } else { ... }  ?>
