| Question : | How can I send variables from a PHP script to another URL using POST without using forms and hidden variables? | |
| | Answer : | You can open an HTTP socket connection and send HTTP POST commands. Here is
an example :
<?
// Generate the request header
$ReqHeader =
"POST $URI HTTP/1.1\n".
"Host: $Host\n".
"Content-Type: application/x-www-form-urlencoded\n".
"Content-Length: $ContentLength\n\n".
"$ReqBody\n";
// Open the connection to the host
$socket = fsockopen($Host, 80, &$errno, &$errstr);
if (!$socket)
$Result["errno"] = $errno;
$Result["errstr"] = $errstr;
return $Result;
}
$idx = 0;
fputs($socket, $ReqHeader);
while (!feof($socket))
$Result[$idx++] = fgets($socket, 128);
}
//-------------------------------------------
?>
Or you can use the cURL extensions for PHP (http://curl.haxx.se). Once you build it and compile their support into PHP, it is fairly easy to do posting stuff (even over https):
<?
$URL="www.mysite.com/test.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://$URL");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "Data1=blah&Data2=blah");curl_exec ($ch);
curl_close ($ch);
?>
This will have the net effect of posting your data to the $URL site, without any header hacking.
You can also do other nifty things with cURL, like retrieve the HTML into variables and scrape through it for neat functionality.
To use cURL you need to recompile PHP or check with your ISP to see if they support it (http://www.php4hosting.com does)
