I found a solution and figured I would share with the everyone.
I was able to switch my request method over to POST (instead of GET). I
am now doing testing to make sure that this will meet my needs, but so
far it seems to work well.
This function accepts the data to post and then returns the resulting
page. the response page does not have to be html, but I have only tested
with text. I don't know how data would work. Data to be posted should be
in name=value&name1=value1 format.
//###################################################################
// post_and_retrieve function
//###################################################################
function post_and_retrieve($host, $path, $data_to_send) {
$errno = 0;
$errstr = '';
$conn_timeout = 30;
$headers = '';
$content = '';
$flag = false;
$lc = 0;
$content_len = 0;
$fp = fsockopen($host,80, $errno, $errstr, $conn_timeout);
if (!$fp || $errno != 0 || $errstr != ''){
return "FAIL errno: $errno, errstr: $errstr";
}
fputs($fp, "POST $path HTTP/1.1\n" );
fputs($fp, "Host: $host\n" );
fputs($fp, "Content-type: application/x-www-form-urlencoded
\n" );
fputs($fp, "Content-length: ".strlen($data_to_send)."\n" );
fputs($fp, "Connection: close\n\n" );
fputs($fp, $data_to_send);
// remote script will now process the post and return a result
while (!feof($fp)) {
$res = fgets($fp,8192); //read 8k/line from remote host
if ($flag) {
if ($lc == 0) {
// first line contains the content
length in hex
$content_len = hexdec(trim ($res));
} else {
$content .= $res;
}
$lc++;
} else {
$headers .= $res;
if (strlen(trim($res)) == 0) {
$flag = true;
}
}
}
// trim our content to content_len
$content = substr ($content, 0, $content_len);
if ($headers === FALSE || strlen ($headers) < 1) {
return "FAIL could not read response content: $content";
}
fclose($fp);
//$return = array('headers' => $headers, 'content' => $content);
$return = $content;
return $return;
}
Thanks,
James
