I need to post some XML to an external web address (Java servlet on another web server) from within a shopping cart written in php. I need example code for how to do this. I also need to know if it can be done to an SSL address.

try this code:
<?php
$url = parse_url('http://somesite.com/path');
$requestData = 'some xml text';
$port = 80;
$requestString= "POST ".$url['path']." HTTP/1.1\r\nConnection: close\r\nHost: ".$url['host']."\r\nContent-type: application/x-www.form-urlencoded\r\nContent-length: ".strlen($requestData)."\r\n\r\n".$requestData;
$fp = fsockopen($url['host'], $port, $err_num, $err_msg, 5);
if ($fp)
{
 fputs($fp, $requestString);
 $response='';
 while (!feof($fp))
 {
      $response .= fread($fp, 1024);
 }
 fclose($fp);
}
else
{
  echo 'ERROR :'.$err_msg
}
?>

I used it a while ago to make an XML-RPC application

I recommend the CURL method, as it has built-in SSL capabilities.

Just leave the usessl/user/pass lines commented out if you don't need to use them.

This script assumes the original data is coming in via a standard x-www-form-urlencoded HTML post method.

<?php
$host = "www.example.com";
$path = "/path/to/script";
// $usessl = 1;
// $user = "myuserid";
// $pass = "mypassword";

      $fp = fopen("php://input", "r");
      $rawpost = fread($fp,9999999999);
      fclose($fp);

      $ch = curl_init() or die("Cannot initialize database connection.");
      $authstr = ;
      curl_setopt($ch,CURLOPT_FAILONERROR,1);
      if ($usessl) {
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,0);
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,0);
            curl_setopt($ch, CURLOPT_URL, "https://${host}:443" . $path);
      }
      else curl_setopt($ch, CURLOPT_URL, "http://${host}:80" . $path);
      curl_setopt($ch, CURLOPT_HEADER, 0);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
      $curlheaders[0] = "Authorization: $user . : . $pass";
      if ($user | $pass) curl_setopt($ch,CURLOPT_HTTPHEADER,$curlheaders);
      curl_setopt($ch,CURLOPT_POST,1);
      curl_setopt($ch,CURLOPT_POSTFIELDS,$rawpost);
      $response=curl_exec($ch);
      $curlerrno = curl_errno($ch);
      curl_close($ch);

      if ($curlerrno) die("Unable to connect to database. Error #$curlerrno.");
      echo $respnse;
?>

whoops, typos! remove the line:

$authstr = ;

it shouldn't be there.

and the last line, $respnse should be $response.

Other than that, it should work, because I am currently using practically the exact same script.
You MAY need to modify this line if the host requires authorization:
$curlheaders[0] = "Authorization: $user . : . $pass";

If that doesn't work, you'll have to figure out the appropriate header the host is expecting on your own.

I forgot to mention that the xml data that you wish to send has to be urlencoded so instead of this:
$requestData = 'some xml text';
so this:
$requestData = urlencode('some xml text');

While I'm around...

$rawpost = fread($fp,9999999999);

just looks prettier by doing:

$rawpost = fread($fp,$_SERVER['CONTENT_LENGTH']);

either one works. the second one is recommended as it is probably more efficient.


This place really needs an edit function, eh Cosmin?

Thanks to both for the help. The curl method looks good but I don't have the module installed. One last thing. I do not want to post as  x-www-form-urlencoded so I changed the content-type to text/xml and it worked fine. However, I am getting all the HTTP response headers back. Can I avoid that and just get the XML response that is coming back to me?

You'll have to strip the headers on your own ... remember that there is a blank line between the headers and the content

compiling/reinstalling php is pretty darn easy itself as long as you saved the old source tree.

make a php script that just contains <?php phpinfo(); ?>

open it via the web, and it will say something like:
Configure command:
'./configure' '--with-apxs=/usr/local/apache/bin/apxs' '--with-xml' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-magic-quotes' '--with-mysql' '--with-pear' '--enable-sockets' '--enable-track-vars' '--enable-versioning' '--with-zlib'

just add "--with-curl" to the end of that.

cd php-4.3.4
#] rm config.cache
#] make distclean
#] ./configure ......
#] make
#] make install

all done.

hey, if i can do it, anyone with an IQ of 146 can

:)

so you're supposed to have 145 ?? :)
... i didn't say it's hard for me to install php on linux or other os but for someone with no background on linux it can be a little difficult.

I suppose it comes down to a compromise between the user using sockets versus the easier method of using curl but reinstalling php. I don't know jack about linux, really. I just have a test box that I mess around with and have apache set up on. If I mess something up and have to reinstall, then it's no big thang.

VMware would be great for someone without a spare box, but then again it costs more than it would to buy a celeron-based pc.
