PHP cURL不会发送适当的标头

Question

I'm trying to send some headers with cURL in PHP and the headers are not sending.

The code is:

$header = array('Referer: xxx',
        'Origin: xxx',
        'Content-Type: application/x-www-form-urlencoded',
        'Connection: keep-alive',
        'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3',
        'Cache-Control: max-age=0',
        'Except:');

and using this:

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
$t = curl_exec($ch);

$sentHeaders = curl_getinfo($ch);

var_dump($sentHeaders);

and in the dump I didn't see Origin, content-type, referrer and nothing... I'm trying to send a POST and it isn't sending.

What I am doing wrong?

edited: Now POST isn't sending:

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, $url);
$t = curl_exec($ch);

Add this option to see the request headers in the getinfo call:

curl_setopt($ch, CURLINFO_HEADER_OUT, true);
