How do I get SSL working in fsockopen?
fsockopen, openssl, php, ssl
Solution
This may sound obvious, but have you tried this instead?
if ($fp = fsockopen('ssl://'. $host, 443, $errno, $errstr, 30)) {
I'm not sure if the `//` is required or not, but the `ssl` and `tls` examples on the PHP Internet Transports page have them.
P.S. I also have a "thing" about included variables in strings, in case you're wondering why it uses string concatenation now.
Problem
I'm running PHP 5.2.6 on Windows, I have `extension=php_curl.dll` and `extension=php_openssl.dll` uncommented in php.ini; as such I can see the following in `phpinfo`: ``` curl cURL support enabled cURL Information libcurl/7.16.0 OpenSSL/0.9.8g zlib/1.2.3 openssl OpenSSL support enabled OpenSSL Version OpenSSL 0.9.8g 19 Oct 2007 ``` I'm not sure that having cURL enabled is vital to this, but since it mentioned OpenSSL I thought I'd include it here anyway for completeness. What I want to do is simple: make a POST request to another server over SSL using `fsockopen`. My code so far is this: ``` $host = 'www.redacted.com'; $data = 'user=redacted&pass=redacted&action=redacted'; $response = ""; if ( $fp = fsockopen("ssl:{$host}", 443, $errno, $errstr, 30) ) { $msg = 'POST /wsAPI.php HTTP/1.1' . "\r\n"; $msg .= 'Content-Type: application/x-www-form-urlencoded' . "\r\n"; $msg .= 'Content-Length: ' . strlen($data) . "\r\n"; $msg .= 'Host: ' . $host . "\r\n"; $msg .= 'Connection: close' . "\r\n\r\n"; $msg .= $data; if ( fwrite($fp, $msg) ) { while ( !feof($fp) ) { $response .= fgets($fp, 1024); } } fclose($fp); } else { $response = false; } ``` This works fine of course if I just pass in `$host` and use port 80. But I really need to send this over SSL, and right now it's not working. `$response` gets set to `false`, `$errno` stays at `0`, and `$errstr` gets set to `php_network_getaddresses: getaddrinfo failed: No such host is known.`. I know that it's not an issue of the server being down, or a typo in the host name, etc., because it DOES work if I go over port 80 unsecurely. The problems only start when I try to switch to SSL. What do I do to get this working?
