php中使用curl处理x-www-form-urlencoded类型的post

<?php
//
// A very simple PHP example that sends a HTTP POST to a remote site
//

$ch = curl_init();
$body = array('userName'=>'15555555555','password'=>'111111');
$postData = http_build_query($body);

curl_setopt($ch, CURLOPT_URL,"http://xxxxxxxx.xxx/xx/xx");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$postData);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));


// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);

curl_close ($ch);

// further processing ....
if ($server_output == "OK") { ... } else { ... }

?>
