Sending very large string via HTTP POST in PHP

I have a mail address on my server which receives emails and pipes them to a php script - piper.php This script then parses the email and retrieves from, to, subject and message parts correctly. Once that is complete, I'd like this script to post this information to a remote CakePHP website to be stored in a MySQL database. I have all of this working except for the posting part.

To post, I use the code given at this link using cURL but I have two questions (code is below for reference only)

function curl_post_async($url, $params)
{
    foreach ($params as $key => &$val) {
      if (is_array($val)) $val = implode(‘,’, $val);
        $post_params[] = $key.’=’.urlencode($val);
    }
    $post_string = implode(‘&’, $post_params);

    $parts=parse_url($url);

    $fp = fsockopen($parts[‘host’], 
        isset($parts[‘port’])?$parts[‘port’]:80, 
        $errno, $errstr, 30);

    pete_assert(($fp!=0), "Couldn’t open a socket to ".$url." (".$errstr.")");

    $out = "POST ".$parts[‘path’]." HTTP/1.1\r\n";
    $out.= "Host: ".$parts[‘host’]."\r\n";
    $out.= "Content-Type: application/x-www-form-urlencoded\r\n";
    $out.= "Content-Length: ".strlen($post_string)."\r\n";
    $out.= "Connection: Close\r\n\r\n";
    if (isset($post_string)) $out.= $post_string;

    fwrite($fp, $out);
    fclose($fp);
}

  1. The code uses URL encoding - I am concerned that this may not work if , for example, my email message exceeds 1MB in text - arent there limits on the size of data that can be sent via URL encoding?

  2. Is there a better way of doing this? Should I establish a PERL script to directly connect to the Remote MySQL database and write? Suggestions are welcome

It's not the CURL.

  1. RFC 2616 does not specify any requirement for post length.

Server has its own post restrictions(Apache for example: http://httpd.apache.org/docs/2.2/mod/core.html#LimitRequestBody). And your php instance could have other options http://php.net/manual/en/ini.core.php#ini.post-max-size.

  1. You could write php(or perl, or python, or bash -- it does not matter) script to connect to mysql directly. But you have to open connections to your database from outside. Remember, that mysql has restriction too: http://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_max_allowed_packet.

It's up to you to deside what to do. Both ways seems legit.
