I am kinda new to PHP however I used JSP a lot before (I have quite information) and everything was easier with Java classes. So, now, I want to perform a POST request on a HTTPS page (not HTTP) and need to get returned cookies and past it to another GET request and return the final result. Aim is to make a heavy page for mobile phones more compatible to view in a mobile browser by bypassing the login page and directly taking to the pages which are also served in an ajax user interface. I am stuck, my code does not work, it says it is Bad Request.

Bad Request

Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please.

<?php
$content = '';
$flag = false;
$post_query = 'SOME QUERY'; // name-value pairs
$post_query = urlencode($post_query) . "\r\n";
$host = 'HOST';
$path = 'PATH';
$fp = fsockopen($host, '443');

if ($fp) {
fputs($fp, "POST $path HTTP/1.0\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Content-length: ". strlen($post_query) ."\r\n\r\n");
fputs($fp, $post_query);
while (!feof($fp)) {
$line = fgets($fp, 10240);
if ($flag) {
$content .= $line;
} else {
$headers .= $line;
if (strlen(trim($line)) == 0) {
$flag = true;
}
}
}
fclose($fp);
}
echo $headers;
echo $content;
?>
