i am using code from here:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.sample.com/demo.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar1=value1&postvar2=value2&postvar3=value3");
// in real life you should use something 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 ($ch);
if ($server_output == "OK") { ... } else { ... }
?>
how to add headers to the post requsst ?
