[PHP] Getting a value back from POST (not the built-in return)
Using a fairly simple fsockopen and POST I'm sending form data to a script which populates fields in a database. Everything works fine, however I've been trying to figure out how to send a value set on the other machine (database) back through the open socket (note: not the return value usually retrieved by fgets($fp etc...) which is then available to the sending machine. Searching via Google hasn't given me an answer. Is it possible? Can somebody help? Syntax would be very nice, I'm not a PHP guru.

Syntax would be very nice, I'm not a PHP guru. i never did use fsockopen, but reading a bit in the online user-annotated manual (http://www.php.net/manual/en/function.fsockopen.php) i found this link that may help you on the sending side: http://www.faqts.com/knowledge_base/view.phtml/aid/12039/fid/51 On the receiving side, if we're talking POST, then you HAVE to be aware of the change in handling them since PHP 4.10, before this version you could just try to read the POST variable directly, e.g. Name went to $Name, or better $HTTP_POST_VARS['Name']. But since then it is recommended to read it through $_POST['Name']. The old way only works if you set register_globals on in the php.ini file, if i remember well. Unfortunately for you i only have a Dutch link to explain this better. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Anything that the receiving Web server outputs is sent back to you just as it would be a Web browser. So, you can read this data just as if from a file (which is why fsockopen is so convenient). Thus, just echo whatever you want to send back. You make a statement that is very conflicting: I've been trying to figure out how to send a value set on the other machine (database) back through the open socket (note: not the return value usually retrieved by fgets($fp etc...) So, you want to send data back through the open socket, but you do not want read this data from the socket. I think you have a misunderstanding here somewhere that will make things difficult for you. What fgets() gives you *is* the data sent from the remote server. If you want to pass data back in a manageable way, you will probably want to output XML, because that is easier and more reliable to parse than HTML.

Re: [PHP] Getting a value back from POST (not the built-in return)
Okay, some clarification. I do indeed want to read what I get back from the socket. Using fgets($fp, 1024) on the sending side (where the socket is opened and the data sent) and return = $variable on the other end (oh yes, the variable has a value as of the return), all I ever get back is 'HTTP 1.1' exactly, or nothing at all in the return value. Can you fill me in on the syntax here? How would you write the fgets statement and how would you define and populate the return value on the other end?

Maybe this example will help. This searches PHP's site for
curl, outputting the HTTP content to the screen. When you
are making a socket connection like this, you get the whole
HTTP response, not just the content. This example uses an
explode() to separate headers from content, which isn't
very safe (if the content contains \r\n somewhere, it
screws up), but it will probably work for you:
base href=http://www.php.net/;
?
$content = php_post(www.php.net, /search.php,
lang=en_USpattern=curlshow=manual);
echo $content;
function php_post($host, $path, $data)
{
$http_response=;
$fp=fsockopen($host, 80);
fputs($fp, POST $path HTTP/1.1\r\n);
fputs($fp, Host: $host\r\n);
fputs($fp, Content-Type:
application/x-www-form-urlencoded\r\n);
fputs($fp, Content-Length: . strlen($data).\r\n);
fputs($fp, Connection: close\r\n\r\n);
fputs($fp, $data);
while(!feof($fp))
{
$http_response.=fgets($fp, 128);
}
fclose($fp);
list($http_headers, $http_content) = explode(\r\n\r\n,
$http_response);
# This only returns the content - modify if you want to
also return the headers
return $http_content;
}
?
