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?
This sample code checks to see if the fsockopen() function is available. To check for another function, change the $function_name variable's value: <? php $function_name = "fsockopen"; if ( function_exists($function_name ) ) { echo "$function_name is enabled"; } else { echo "$function_name is not enabled"; } ?>
The function stream_socket_client() is similar but provides a richer set of options, including non-blocking connection and the ability to provide a stream context.
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.
